Me too! In 40 years of BP type mills, 2 with power on all 3 axis, probably no more than 6 with x and y power feeds. What a simple solution! Lol! Shame on me!
If you add a perpendicular length of rod, you can spin the now T-shaped adapter with the same powerfeed tool as the X and Y handles. That way you don't have to rechuck different tools into the drill. You might also have enough leverage to fine-tune the knee height at the end of the move.
I used a similar style drive for my z axis. I've since changed it to engage in three places instead of just one after a freind of mine broke one of the teeth on his Bridgeport style mill (off shore copy). I don't believe it would have happened on a real Bridgeport though, mine was fine for 6 plus years driving in one place before I changed designs. The way the tooth sheared off on the copy suggested the steel was very brittle. Thought this was worth sharing for any Bridgeport clone owners.

Another great video. I would love to see a video tour of your shop. I love how you gear your videos to the diy people. You are truly the finest craftsman out there. For new people learning the trades you need to do a bio with pictures and past and present projects.
I'm glad you liked my latest video, and a few people have requested a shop tour. I may do that at some point. You bring up another good point - TH-cam has given me a worldwide audience, but people just getting to know me through short videos often don't realize I've been doing this work for over 50 years, and that I have some 'cool' projects under my belt!
@@RonCovell you really do have some amazing projects. I think those 50 plus years and your progression will inspire people. I got my first book from you when I was 16. I'm 47 now and my career progression is do to people like you and hard work.
I do own a rotary table, and I considered making a 9 pin collar - but after imagining a drive with a single dog, I went that way, and I don't regret it.
But I just LOVE lowering the knee down to drill a pilot hole, only to bring it right back up to use and endmill in the hole! Fantastic idea Ron, keep it up!!
Great one. I've been wanting to make one of these adapters for my mill but didn't want to spend the time setting up the mill to cut the slots. A fabricated adapter is now on my list of things to do (after this weekend). Jere
Jere - One of my commenters informed me that you can buy these for about $34 - in hardened steel.

I have never seen such beautiful chrome handels on a mill or lathe. You sure love your equipment and clearly takes pride from what you do (hope this translate well, English is not my first language)
Well, thank you for the compliment. For what it's worth, my milling machine is an import copy of a Bridgeport, and I think most machines of this style come with chrome handles. Your comment reads perfectly in English, so your translation is superb!
I've done a similar thing for my Pallas mill, but I use an Allen key to fit in the drill chuck, I've dozens of odds and sods of Allen keys, I've collected/picked up over the years 😊😊👍
Great, simple solution, Ron! That odd-ball face groove was a "too difficult", read time consuming, to take time out to make. 👍😎. Thanks for your time and sharing!
One project I have my apprentices do is to make a dog clutch adaptor for the Bridgeport knee. It is actually quite simple. With an indexing head or table. I think it is a good instructional project.
Enjoyed….simple/smart…add/weld a nut on the tube then you can use a wrench to make small adjustments without removing the drill and installing the stock crank (liptonized)
Great tip! And this is the first time I've heard the term 'Liptonized' - presumably named after Tom Lipton. I've known Tom for 20 years, and he's a great guy - on many levels!
As a Mechanic I have Broken Sockets and Extensions. Just Weld one to the End. On your Drill use a Adapter for whatever Drive Socket or Extension. You can make All over them the Same Drive.
that's excellent! is there any disadvantage to having only one dog? as for adding more, I assume that would risk distorting the tubing a bunch from the extra weld heat?
Attach a similar device to the lead screw on my lathe- and cut any thread know to man. Although some serious synchronizing would have to be achieved! HA! Good idea- I will use this idea in my shop. Thank you!
@@RonCovell How about a thread that starts out fast, then torques with finer threads when reaching the cinch-down final torque. Perhaps an ultimate sheet metal screw! I am only trying to think out of the box. Nothing ventured, nothing gained. Here at ODD Parts Fabrication- this sort of thinking has earned daily receipt of parts for restoration for over 85 Ferrari Maserati dealerships around the world. We are very busy. The only thing that we do not fix is marriages! HA! Thanks for your help and Inspiration. IE- we repair Vacuum canisters using a bead roller.
Just imagine all the shoulder and elbow strain that could have been prevented! I've never actually seen how slow the knee moves on those mills, and I think I would go insane if I had to do routine work with one.
power feed means its going to be a constant feed rate vs load, not some guy doing the elvis on a de-walt that has a 256 position digital pot hooked to its trigger .. as far as knee adjustments if its a bridgeport compatible castle nut arrangement, they already make them for peanuts on the usual sites ... we don't have a welder at our ship and its like 30 bucks online
You are correct that this really shouldn't be classed as a power feed, because it's too fast for most cutting, and the speed isn't consistent enough. I didn't know that a ready-made adaptor was available for the knee. That's pretty interesting!
Could you put a cup on the outside of that new one, with some long fingers and make it "universal", so you don't have to swap between the traverse and knee tools?
Nice one Ron. I would suggest that you need to lubricate your mill ways though as they look a bit dry, and that certainly lessens the amount of effort needed. I use Shell Tonna myself although there are plenty of other suitable oils out there. Especially for machines that are not used often there is a temptation not to lube that often, relying on 'I did that last time' but dust (especially wood dust) will dry the sliding surfaces out. I use dust covers for that reason too.
You bring up a very good point. My machine has a 'one shot' lubricating system, but I suspect that some branches of it have clogged up, because even after pushing the handle, some of the ways remain dry. Thanks for the tip, and I'll look into it!

demonstrating "beauty in simplicity" very well.
Thanks - often simple is good!
I can’t imagine working on mills for decades and then just now learning this. Glad TH-cam is here while I’m young
You know, I had this idea for years before I actually made it. Now I wish I had done it years ago!

@@RonCovell and add U formed ends to the T-rod for a less backlash version of the table driver
Pretty handy, easy to make, and I've got all the materials to do it, thanks Ron! Now... time to get a mill to use it on... 😉
Yep, you'll need a mill to make this project worthwhile!
Ron you are such a brilliant man, yet such a patient teacher
I'm so glad you enjoy my videos!

Wow - I'm shocked to hear that. Thanks for reporting this incident - we certainly don't want people shearing teeth off their machines!
Definitely the simplest solution I've seen so far. Very easy to make. Thanks for sharing Ron, take care!
You bet!
We are also honoured that you want to take the time to show us the tricks that took you a lot of years to learn.

Glad you liked it!
Nice simple method for mill owners who don't have a rotary table,I like it.
I do own a rotary table, and I considered making a 9 pin collar - but after imagining a drive with a single dog, I went that way, and I don't regret it.
Really just amazing. Then you have someone that really take pride in his job. And simplicity is everything. Pure gold. Keep it up sir.
Thank you! Will do!
Great idea, Ron. Simple and works perfectly. 10/10
Glad you like it!
The world is better because of your videos. A+ Ron
Wow - that's a high compliment, indeed!
But I just LOVE lowering the knee down to drill a pilot hole, only to bring it right back up to use and endmill in the hole! Fantastic idea Ron, keep it up!!
Well, it is good exercise to work that knee up and down manually!
Now I know what I'm making tomorrow. I don't have tube so I'll turn it on the lathe. Thanks Ron
You could do an even better job by turning the hub on a lathe.
Great one. I've been wanting to make one of these adapters for my mill but didn't want to spend the time setting up the mill to cut the slots. A fabricated adapter is now on my list of things to do (after this weekend).

Great point! I haven't broken any handles yet, but it could happen!
@@RonCovell I always had extras around, we would use air drills and impact guns back before batteries got so good.

Glad you liked the video!
A very wholesome ending!
Thanks!
Shoot, we're honored to learn from a master.
Thanks so much!
I machined mine. It was fairly straightforward forward.
Great!
I'll be making one of these tomorrow. Thanks for the idea!
You won't regret it.
Nice work. We shared this video on our homemade tools forum this week :)
Awesome! Thank you!
I guess I know what my next milling machine project will be. Thanks Ron!
Go for it!
That's a great idea! I get tired raising and lowering the knee on my mill every time I want to change a collet or end mill and it takes so long...
Glad it was helpful!
As usual an excellent idea and and an excellent execution of the idea, nice 👍.
Thank you! Cheers!
Thank you Ron - kind regards from John Spargo in Cape Town

I just bought a drill adapter that has all cogs for $35 on eBay, quality was fantastic
Thanks for letting me know. Honestly, when I made this video, I didn't know that product was available!
Awesome...now all I need is a Bridgeport mill to stick it on. 👍
Maybe one will fall in your lap!

My mill has 3/4 nuts that hold the x and y handles to the screws. I welded a dog to the side of a 3/4 socket and made a all in 1 feed piece.
Great!
nice work,Great video
Thank you very much!
Awesome work!! Thanks for the content
Glad you liked it!
Outstanding!
Glad you like it!
Thanks
No problem!
If Ron says “this is fantastic “, then who am I to argue?
Yes - it sure beats hand-cranking the knee up or down a significant amount!
Great job!
Thank you! Cheers!
I've gotten an extra nut or handle and welded a 1/2 drive junk socket to them. Works about the same.
Great idea!
So cool how make more easy to mill
Glad you liked it!
that's excellent!
is there any disadvantage to having only one dog?
as for adding more, I assume that would risk distorting the tubing a bunch from the extra weld heat?
Of course more dogs would make the driver more robust, but it's pretty hard to imagine anything breaking, even with only one dog.
Thanks, very useful idea!
Glad it was helpful!
Very nice
