Interesting approach,Mark and well done.Thank you.
Glad you enjoyed it. I've used this drill press a lot and it works fantastic.
Great build thanks for sharing.
Thank you for the video. Very well thought out, and very well built.
Thanks!
Great build, really like that you care about cost and using whats on hand.
Another great build. Enjoy your ability to think outside of the box .Thanks for the post.
Thank you sir!
You Sir, remind me of my Uncle who has passed now....but, he was a machinist & a perfectionist as you are. Thanks for this Great Video and showing us the "How-To's" of your build. I enjoyed this👍🏼
Great build , and you can still swing the head for off the side drilling of the table.
Looks good . Ill put this on the back burner for myself . The hand crank will be fine for occasional use but you could always chuck the shaft into a cordless drill if you were going to be going up and down a lot with odd jobs .
Winky's Workshop that is one of the best ideas I've seen thank you for sharing
Thanks, it's really working out great. I should have thought of this years ago!
Great idea, and video!
excellent job,I love how smooth it works!!!
Thanks. Every drill press needs to be made like this. It works great!
Great Job.
I like your beef up drill press project, I noticed that your lead screw support bearing assembly is almost the same as the spindles on my mower deck that am working on right now. However your bearing configuration is 100% better with tapered roller bearings and I will be redesigning the 3 of them to improve their longevity. Thanks for the Idea.
Glad you liked it. It really is a lot better than a round column. Tapered bearing are great... and not super expensive. $12 buck for a pair on Amazon (LM11949 LM11910).
Very cool
Looks like it turned out great!
Ingenious! I like my drill press but hate the table height adjusting mechanism. Your project provides a perfect solution!
Thanks, I'll have to say I have used the heck out of it! I love it. The only thing I might change later is to add a motor to the lift screw but really it isn't bad as is
I enjoy your videos
awesome build.....another project now on my bucket list.
Go for it! I also added a motor to the lift. It was basically a harbor freight drill. An easy upgrade. See the video.
Thanks for this idea and project, definitely on this list for a build for myself.
This is one if the best ideas I’ve seen, the way you have made this is quite simple but very affective turn the normal drill press into a much user friendly drill press, I will probably end up doing this to my own as mine has only got the half size/ height post, I really like your cross slide table which i think is a must have, I’ve looked at mine many times thinking of a way to build one, thanks very much for videos mate, very enjoyable to watch, Cheers Matty in Australia 🇦🇺
Hmm? 2 years ago. I stumbled on this old comment that I apparently overlooked. Thanks for your kind words. I hope you are doing well.
that's a great idea. with the x y table, you could use that set up for light milling too
I have a mill now but I tried the table for milling and it was nowhere near solid enough. My table is very accurate for light work but even drilling large holes is a problem. I have however used it in wood with a router bit and it worked fantastic!
Very nice, I've been watching your videos for months, i didn't realize I wasnt subbed to your channel till now... i fixed that..
Good job....and very clever thinking, not many people would think of re-inventing their drill press this way..........that mill looks like it could do with a similar upgrade too.
Yep... I just posted one o the mill. Thanks for watching!
Very interesting fix. But I do agree with you about the bigger sprocket , it appears that it is 1 to 1 right now you could cut your number of turns in half with that one change. Very good job.
I may do that... it's easy to try.
Really nice work thinking outside the box!
Thanks! I've used the heck out of this drill press,
Great video, thank you for sharing!
Your welcome
Awesome video, love your ideas, gave me some good ideas on converting a drill press to a small milling machine, thanks for posting.
Thanks you sir. It really isn't solid enough to mill but it rocks for accurately drilling.
Great job! Good project!
Thanks, I'd love to find a motor for the screw for under $50 bucks
Amazing job!
Thank you!
Great build, great idea.
Thanks, it really does work great. If you are interested the drawing are available. Search for "Measured Drawings for the SQUARE COLUMN DRILL PRESS" (youtube video)
Great job. Got to build mine now.
Thanks! The most critical aspect is getting the top tube welded on straight. You could also simplify the bearings at the top of the lift screw. Just use a sleeve bearing with a thrust bearing under the sprocket. Good luck!
Very clever.
good build...we all have that drill press issue.
Good build, good video. I did notice the stand has some shake to it. I am in the process of building a vise stand with a regular vise on one end and a blacksmith pole vise on the other. If you want stability, I used an 18 wheeler truck brake drum, welded a 1/2" plate on top and welded a 4" pipe to it with another 1/2" plate on top with the two vises on either end. This brake drum makes a real firm stable base... enjoyed, good idea..
Thanks Tommy, Yes I need to address the wobble. I undersized some part of the stand. A brace will resolve the problem. It's on my list... and there are lot of things on my list! But i will get to it. Thanks again and thanks for watching
I love the idea of adding that precision to a drill press... And I have a Wrong-Fu (round column mill like yours) I have tried many things to increase it's accuracy - and I believe that a square column would work... But clearly the installation details would be much different... Maybe you might take on such a project 🤔
Here ya go! th-cam.com/video/_2JXRt3_4qw/w-d-xo.html
I enjoyed your build on the drill press. I may do similar to mine. Thanks for the great vidio.
Thanks. If you make something like this keep in mind the top tube alignment is super critical.
Dear Winky, this is a very useful idea and a great solution to a problem that anyone with a drill press faces. Thirteen turns per inch is a little slow, but a fine adjustment. If you doubled the diameter of the handle sprocket, your table will rise more quickly for each turn, ie 6.5 turns per inch. Thanks for showing us how to make an elegant piece of hardware.
I actually tried that but after making the crank longer for additional leverage it slowed things down. I now have a HF drill motor attached. It works fantastic! At some point I'd like to find a little gear motor (hard to find at a good price) but for now the drill works great.
And thanks. I use the heck out of m drill press. Very very handy.
Fantastic problem solving inproving to make something work for you yousing a hole range of skills and salvaged materials in the home shop inviroment a joy to watch and a inspiration for this throw away society we live in many thanks all the best
Thanks... and I agree about the throw away society.
By darn I watched both parts , I subbed to ya long ago . You come up with the best ideas .. ENJOYED !!
I LOVE Tapered Roller Bearings! When needed, they are the best! Great build, Winky. (I just added you to the Dictionary. Now EVERYONE will know who Winky is. Well, at least how to spell your nickname. :-) ).
Yes, I know, it is only in "my" Dictionary. Well, darn it, it should go directly to Webster!!
I watched this when it came out but had to watch again... Nice build!!! Thanks!!!
Thanks Danny, this video is not as popular as some of my other videos but in my mind this is my best project. I use my drill press almost daily and love it. What I can not figure out is why companies like Jet and Grizzly have not made drill presses like this. They make drill presses that cost close to $5000 but they retain the round column. It doesn't make sense!
@@WinkysWorkshop Lots of things don't make sense these days. This is the way we have done it for years and enough sheep continue to buy it so why change.... A mind set way to prevalent in our world!!!
@@dannywilsher4165 - I worked for a printing company for 39 years up until I retired in 2019. In 1985 they got rid of 10 engineers (reduced to 2) and said we are going to rely on press manufactures to provide the machines we need. The plant was huge and employed 900 people! In 1995 they moved me from running a press into a job designing machine improvements. I'm not an engineer but I do have a good imagination. Generally speaking, people would rather live with the certainty of a bad situation than to experience the uncertainty of any change even if the goal is to improve (but NOT me). The first 2 years I was in this job I had to prove myself but after that everyone wanted me to make changes. Nice to be trusted but also overwhelming.
@@WinkysWorkshop Sounds like an interesting job. Designing machine improvements seems like what you excel at. You are very talented and an awesome designer. I have 2 engineering degrees and like you, I love to make things better. I never look at anything and think it is ok like it is. There is always something that can be changed to improve on the original design. Thanks for the comments, I enjoy the conversations!!!
@@dannywilsher4165 - Thanks for the compliment. That means a lot coming from an engineer. The engineer I worked with never had much good to say... although he occasionally he was helpful. To be honest, I think he saw me as a threat. I fixed quite a few problems he should have been addressing plus I fixed a couple of his designs errors. Big egos are hard for me to deal with.
nice!!!
Great job. Anything to make the job easier but stay accurate is a winner. I think a small electric motor will make the job even easier. :)
Clever build - lots more work than it was appearing at first; but I can't see how it would be made much simpler without compromising its operation.
Thanks. I'm sure there are shortcuts but not many. Thrust bearings on the lift screw might be easier than the tapered.
good work
Beautiful sir! Very nice build! :-)
Thanks!
Great Idea Winky. When you do draw up some plans, I would be interested in a copy.
I have them mostly drawn. I drew it all before building but they are not complete. I'll post a link in the description below the video. Actually... Maybe I'll make a 20 second video and post it in the description. That way those that watched this video will be notified... Or those that are subscribed will (be sure and subscribe!).
@@WinkysWorkshop Thank you, I am a subscriber and also I get notified when you do post anything.
Hello Frank. I posted the drawings with a short video. You can find it on my channel or run a search. The video title is: Measured Drawings for the SQUARE COLUMN DRILL PRESS. THANKS!
Nice job, you can sure make yourself a lot of useful items if you have access to a lathe and a mill.
Thanks, yeah, especially the lathe!
Very very good 👍👍👍
One of the things i really like about this project is it allows someone to modify one of those cheap stubby bench mount drills up to a pedestal drill cheaply . Those cheap asian made drills come up on ebay and craigs list all the time so with a bit of work and some scrap steel you end up with a half decent pedestal drill . One issue with those drills is how bad the table arm flex is and your system looks like it fixes that ! I would just use an old electric drill to drive the table lift , i did this on my mill and the whole set up with a new cheap drill cost me around $30.au .
Excellent video Winky !
I actually used a drill motor on a wood lathe (made like a metal lathe) that I built. It worked okay except for the fact that it coasted to a stop... which would not be a problem with the drill press. Yes you are right about the small cheap dill presses. You could make a nice drill press without spending a bunch. Although sometimes they have other issues. I had one for years and the quill travel was only 3.5-inch plus is had a lot of movement. there was no way to tighten the quill. Thanks for the great comment.
So many videos here on TH-cam are talk talk talk talk and when they get to show machining they put horrible music on and go fast forward I hate it, but not yours, you're video is perfectly put together, just the right amount of talk and machining, I love it especially the small clips where you put things together and say nothing the only thing we hear is the sound in your shop, it great 👍 I clicked the subscribe button.
It's a really great invention you have made, I have the same problem. Hi from Denmark.
Thanks for the great compliment! Some my older videos show too much detail. I try to learn from my mistakes.
awesome vids
Thanks!
That is gorgeous. I also re task bits of metal. People throw them away. (Free).
Very Nice! Could put a bigger sprocket on the hand crank to speed up adjustments.
True, although I now have a harbor freight 3/8 drill connected. It works fantastic. - Thanks
Nice build, suggestion though. Make a nice T-handle to lock the table to the column instead of using a wrench.
I agree. Done, thanks
VERY impressive build. This has been one of the best projects I have watched in a while. One suggestion I would make concerns the table locking bolt. It might be an idea to set the bolt in a locked or almost locked position, then weld an "L" shaped handle to the head so as to do away with the wrench. Thank you for sharing.
i guess Im randomly asking but does anybody know of a tool to get back into an instagram account..?
I somehow lost the account password. I love any tricks you can give me.
@Ricardo Jon Instablaster ;)
@Drew Preston Thanks for your reply. I found the site thru google and Im waiting for the hacking stuff now.
Looks like it's gonna take a while so I will get back to you later with my results.
@Drew Preston It did the trick and I finally got access to my account again. Im so happy!
Thank you so much, you saved my ass!
@Ricardo Jon You are welcome :)
This is a great build and I am glad you did it. I have never been a fan of the off the shelf cheaply made aluminum table lifts. I have thought about this for some time. However I did not put pen to paper. In addition though proud of my shop you have way more tools at your disposal than I do.
Any idea of when the plans will come out? If they are out please provide link.
Keep up with the great ideas....
Thanks Will from Akron, Ohio
Thanks, Currently I have a cheap 3/8" drill driving the lift screw. It works fantastic. Very quick. The fact that I never lose my horizontal position when I move the table is a huge plus. I also added the X Y table so I can do some very accurate drilling. I love it.
Impressive..
Thank you sir. I've been looking for a gear motor to replace the crank but never found one cheap enough. Last week I mounted a harbor freight 3/8" drill in place of the hand crank. It works great! I can't imagine why they don't make drill presses with square columns commercially. It's very useful!
Gear ratio opportunity with larger driving sprocket. I think the most interesting part of this project was how you aligned and jigged the tube to the column for welding. No easy undertaking.
I agree, perhaps double the size and go back to the longer crank.
Milling the notch in the tube made the alignment fairly easy although I never dreamed I would get it aligned so perfect. I think working with thick wall tubing helped a lot... much less distortion when welding.
Great lift. For a drive motor I did see where one guy used a wind shield wiper motor in the "low" speed. More torque in low speed and 12v-but I don't I know if you can reverse it. And they are cheap.
Thanks! Yeah, I've thought about those... but the voltage requires a power supply.
Job well done sir, alsome
Thanks, it was a lot of work but in my opinion, well worth the effort.
Nicely Done ! Very interesting project. Out of curiosity do you think there would be any vibration dampening benefit to filling the column with sand or some other material ?? It's a pretty stout piece of equipment already .... just thinking out loud.
If you look on eBay under windshield wiper motors you can find some new ones kinda cheap. They will lift your table and work with no problem. They are 12 volt and reversible.
Here’s a fun idea💡 You could get an old corded still from a garage sale and hardwire it into the drill press. And then that would be your up and down motor! 🤔
Thanks, great minds think alike! th-cam.com/video/3p5AD3kFqTY/w-d-xo.html
Did you use a small sprocket for the hand crank to allow motor use in the future? If not why not go with a large sprocket like on a bicycle, would raise and lower much quicker? That is an outstanding drill press!!
It was related to the amount o effort needed to turn the crank. I ended up putting a HF drill on it with an even smaller sprocket. It worked great although it looks kind of funny with a drill hanging off the side.
Why they bild this things likes this? Fantastic job.
I think the round column is cheaper but the round column also has a few advantages... although I don;t often need to swing the table out of the way.
What a great idea. If you're still considering an electric motor to adjust the height, how about a motor from a power window used in most cars?
I'm glad you like the video. Thanks for the suggestion, I ended up using a HF 3/8" drill. Aside from looking funny it works great. It's variable speed, reversible 110 V and has plenty of power. I used the smallest sprocket I could find (I think 9 tooth). Full speed on the drill is about 4500 but for a big move it's nice to have the speed. The window motor is a great idea for all kinds of projects, I just wish cheap power supplied were easier to find. Thanks for watching.
I have seen a lot of machinist on here use a windshield wiper motor for lifting and for automating their cross slide tables. They are DC motors so you can add a double pole double throw switch and a 12-volt power supply to run and to reverse the motor.
I've been looking for a good power supply for a while... one large enough is high priced.
I agree the drill press needs a motorized lift. I'm thinking a HF 3/8" drill for 20 bucks
@@WinkysWorkshop That would work as it did on your wood lathe. I use dc motors from treadmills to power most of my stuff. You can also get the ac to dc 12 volt controller from the treadmill that will handle up to a 4hp dc motor.
@@capman911 - Thanks for the tips. I need to look for these!
@@WinkysWorkshop I am working on a project now that I am using 12volt dc wheelchair motors that are gear reduced. I am building an off-road wheelchair to hunt from. Ebay about 60 or 70 dollars apiece. Your welcome for any help I can give.
Brilliant job Winky mate.. I bought a cheap drill press, a bench top model. It's my 1st ever one but I'm struggling to use it atm. It has those daft round columns and it has a real tendency to move on me even when locked down.. I might take it apart and try and key one side of it in the future to be able to lock it and keep it locked on tight.. The problem is I'm not sure how sturdy/thick the metal column is so I might look to get a better one in the future. It has the belts and pulleys system on it.
Old school way but I like that about it which means I can change speeds when I need to..
So is it possible to use a small bench drill as a milling machine or is a dedicated machine needed?
Thanks for another great video mate.. Great job and the column and winch..
Even a large industrial drill press should not be used to mill although they do work well for wood.
I really like that! How did you square up round tube with the square column at the top where they are welded together so that the chuck is parallel the square column?
Thanks, this part of this project was very critical but apparently I got it right. Also the guy that welded it for me is the best welder I've ever seen. It didn't move at all when he welded it.
Are you an engineer by trade? Very well executed. Thanks.
Ha... thanks but no, I'm not an engineer. I'm retired now but I used to tell my boss "if I'm doing an engineers job I should be paid like one". I think I'll copy your comment and send it to him.
love the idea and the execution I am half way through building a bench top version mine about 48 inches high and being in the UK im doing it metrically lol one question did you fit any form of bottom bracket on your threaded rod ? I have an old treadmill motor i am thinking of fitting to mine
Thanks. After making the video I actually put a cheap hand drill in place of the hand crank. I put a small sprocket (11 tooth I think) in the drill chuck so the threaded rod turns about half speed. It's still a little fast but the speed is nice at times. I need to put a bracket with a bushing on the bottom of the threaded rod now. It tend to wasn't whip around (wobble?) at higher RPMs You will love the square columb. I have another video on building an X Y table that you might want to watch. The square column and x y table make a great pair.
Sweeet! Consider hex connection on top of the crank shaft, hook up battery drill for the odd occasion when you need speed up or down...
Thanks, I've used the drill press a lot lately and I'll have to say, it works fantastic. The table is a little slow but most often you don't move it very far, maybe 5 or 6 inches. For this about the crank is not a problem at all.
I solved the alignment problem by screwing the elevator rack to the column. I always push the table clockwise against the rack to take up any slack. It may not be an alignment that I can measure in thousands, but it always ends up close enough.
Thats outstanding! I thought about doing the same with my round column mill. My drill press didn't have a rack. I considered a bar out to the side but I had to build a lift anyway. I currently have a harbor freight drill motor running the lift screw which is amazingly convenient! If you use your drill press much you might consider a motor on the lift. Thanks for your input. This is the best option considering yours have a rack.
How about a counterweight for the table?
Ya do know about double drilling,it is as good as a reamer,drill a couple of thou under size and then run right size drill,be hind it,
If you round the Corners even a chamfer on the very edge of the lip length on second drill and slow speed down ,can obtain mirror finish on a sized hole,,and yep plenty of lub.
Cool... That makes sense. I'll keep that in mind for future reference.
Nice build Sir! Wondering how the top tube you made was aligned to the square tube when welded on..I'm thinking that would be a very critical placement..
Thanks! Yes the top tube alignment is absolutely critical. Even .010" off would be hard to tolerate. I milled half the diameter off for about 4 inches. When clamped against the column one axis is aligned. Then I used a 2 foot straight edge against the side of the column with spacers to align the other axis. When welding (which I had a friend do) was spot welded in 4 spots to stop movement before welding the whole length of the tube.
Πολύ καλό φίλε Καλημέρα
Ευχαριστώ πολύ
hi Wink,
,i was just thinking instead of you using the hand crank,how about placing a windshield wiper motor from a hyundai,,nice an small in size.with a small wall wart power supply or cheap ac to dc power supply. a momentary double pole double throw switch and you will not have to crank it up or down,just thinking out loud.
That's a great idea but I bought a harbor freight 3/8" drill and used it. It cost me $14 bucks with a coupon. It was super easy to mount. I just made a clamp that fits around the area behind the chuck where an axillary handle would mount and then clamped a shaft and sprocket in the chuck. It look funny but works great.
What is the brand and model number of your mill? I like it!
I love my mill but it really isn't a very good one. It has a round column much like the drill press did although now that I use my drill press for all drilling it's not much of a headache. The mill was sold by Enco but it's an RF-30. They are no longer made but they were very popular for small shops so there are many out there. There are several variations out there and they were sold under many names.
All that nice work and you used a 1/2 13 TPI lifting rod instead if a 3/4 10 TPI?
Haha... It seems to be totally adequate although IF I was concerned with measuring a table move the 10 TPI would have been handy. I was a little concerned about it acting like a torsion spring when the table was low but it seems to work perfectly. Of course if I was going to go all out I would have used Acme threads.. ... just didn't want to pay for the threaded rod and tap... also I had 2 sticks of 1/2" on hand.
@@WinkysWorkshop Use what you have for sure.
ACME taps dont fall out of the sky for free but I wish they did.
Thanks for the reply.
could you not power it with a drill like people do om the knee on mills maybe easier then cranking
Yeah... I build a wood lathe built like a metal lathe and powered the cross feed with a hand drill. The crank actually works pretty easy so I might not get around to putting a motor on it.
Looks good. Now, blow it apart and give it some lovin' and some paint. Or better yet, some powder coating.
Great project! Wouldn't it be nice if they put a square tube on the drill press in the first place? I've found you can us an ACME thread with a more coarse thread and move the table with about the same effort.
Thanks... and yes, I probably should have used acme threads but I had 8 foot pieces of 1/2" on the rack. Since making this video I added a Harbor Freight 3/8" drill powering the lift. It's fast and easy. YOU ARE EXACTLY RIGHT! Why in the world don't drill press manufacturer at least offer a drill press with a dovetailed column? You know I wrote both Jet and Grizzly and sent them a link to this video and asked them why. Only Grizzly responded... and they simply said, we have mills that do this. Grizzly makes a nice dill press with a beautiful mill table and "ROUND COLUMN" with a 4.5 inch quill travel. They only thing I can figure is they like to frustrate people.
@@WinkysWorkshop Thank you for the reply. I was an engineer for GE and we had a term for the response(s) you received from the manufacturers; NIH ( Not Invented Here). If WE didn't think of it, we didn't like it :-). The only mill that will keep in alignment is a knee mill. Even Grizzly's small mill doesn't stay in alignment.
@@simguns8388 - Yeah... grizzly has some knee mills. I have a drill mill with the round column. It's a joke. Needless to say I seldom use it for drilling. Occasionally for a very large hole but that's it.
@@WinkysWorkshop I had one of those for years and HATED that it wouldn't stay in alignment when changing the Z axis. I bought a Sharp knee mill with a power table feed and never looked back :-)
What's planned for your next project?
I'd be curious to see how much that table moves, when its lowered like that
I made a follow up video on the accuracy.
@@WinkysWorkshop wow, I'm impressed
@@EitriBrokkr - I was a bit shocked myself
Can I use a piece of my existing column instead of turning down something new?
I'd say that is a good option as long as it is thick enough to get a good weld. My column was less that 1/8" thick.
I enjoyed the video. So do you have any plans to put a square column on your drill/mill?
Just put a motor to the raising mechanism.
Spacers underneath the bolt (suggestion)
The clamping bolt? I put an extended T-handle on there after I made the video. Thanks for watching.
Why does your power machinery run rough and noisy? Bearings?
The drill pres is normal, the grinder has a bad bearing, the mill has a vibration in the motor that is not bearings (no idea) but... I suspect you are mostly talking about the lathe. The lathe is a 1943 Logan with manual change gears. These gears are manually changed to set the feed rate. I might be able to make them a little more quiet by adjusting the backlash but really this noise is normal for straight cut gears. If you go to 5:28 in the first video you will see a rack of gears on the wall. To be honest, I've had several people with older lathes ask me how i got my gears to run so quiet.
Great idea. I just bought a 20" Drill press with 2HP motor. Has a 4" round mast which is barely 1`/8" thick wall,
Pathetic. Did you ever draw up plans? I will pay whatever you want for them. Thanks again.
Yes sir, here you go. drive.google.com/open?id=1YfY...
cool . just use an electric drill to power the table
Thanks! Yes i have considered that. I used a drill for my wood lathe feed (see Wood lathe made like a metal lathe)
Great example of old school ingenuity...

Winky,
After drilling a hole that you want to tap simply put the tap in the chuck, turn on the off the motor and guide the tap into the hole to start it.
That works but ultimately you will have to use a tap wrench. If you are talking about the lathe, my lathe doesn't really go slow enough to do that.... or at least it's risky. I've taken the risk a few time but I didn't want to break a tap on the video :o)
Sounds good! All the best to you.
Eric @@WinkysWorkshop
Winky...Could I obtain a copy of your plans for this build? If there is a cost, I'd be willing to Paypal you the funds. Tried to find contact info from your channel page, to email my request. No-go. Great project, and I def. need to modify my d/press column....Subbed!
Search for this video or you can find it on my channel: Measured Drawings for the SQUARE COLUMN DRILL PRESS
Say goodbye, counterweight. ;-) (That did serve you well, but the "unbridled" mass sucks. Am I right?).
Are you speaking of the table weight? My x y table weights about twice what the original table weighed but the lift screw easily supports the weight and even without the lift screw the clamp would easily stop the table from sliding down the column. The effort involved with moving the table is minimal although significantly more going up vs down. I've got some ideas for a better x y table. I love the one I made and it's very accurate unless you put it under a large load like drilling over 1/2". Hopefully I can keep the weight down too.
Nice build but 13 turns for an inch of travel... 78 turns for 6'' put a motor on it lol
I totally agree.... still looking for the right gear motor. I think 600 rpm would be nice although I could go slower and make the drive sprocket larger. I could also go higher rpm and make the drive slightly smaller.
An easier fix is just to add a second column
I'm not sure that would be any easier but certainly it's a good option. I ready can't imagine why drill press manufacturers don't offer this as an option. I know a round column can be a plus at times but many have no need for it
Fill that column full of cement
That might stabilize it a bit but it really needs better bracing at he bottom.
@@WinkysWorkshop some of those commercial columns are 1/2 thick walls. Nice build however, and that concentric cam and roller bearings was a nice touch .
@@mikemullenix6956 I think mine is 3/8"... but I may be wrong, still heavy.
A drill press is NOT to be used as a press. Other issues with his techniques. Drill and reaming speeds to mention a couple more.
Yep... you make do with what you have. I don't have an arbor press and my drill press and mill don't go slow enough. Lots of oil and hope I don't burn a reamer. Obviously a little common scene helps. I don't press 2 tons and I have never burned up a reamer. You got me on drill speed... to lazy to change the speed.
First
