I haven't found another youtube channel I enjoy as much as yours. Your easy to listen to and very educational. Thanks for another great video.
Thank you very much, I appreciate the encouragement. Keep watching
I agree 100 percent with that statement great work as always
Loved it! With as crazy as things are getting..sitting here having coffee and watching your videos sure takes a person's mind off of the "news" of the day. Thanks, Mr. Pete! :-)
Thanks, it’s business as usual usual here
We will be ok :)
That Clausing mill is such a great size for the home shop, looks great cutting that gear rack, quality job Tubalcain
I watched just for the pure pleasure of it. I was not disappointed. Thank you Tubalcain.
"...Just dropped in to see what my condition was in"... A big thumbs up, as usual.
Thanks
Cutting a rack looks like a job for Mr.Re-Pete, crank the handle and Re-Pete then crank the handle and Re-Pete.
Please keep up the awesome work!
Yes lol
Hello from Spain. I follow you since some years ago. Great videos. All what I know about lathes and milling machines is thanks to you.
Thank you very much keep watching
Thanks for sharing Lyle.
I was just watching your video where you were unloading sand. That’s a mighty big job that you under took. When I was younger, I did a lot of heavy work like that even though I’m not very big. The weather is still cold here
@@mrpete222 Yeah, Its a big job for sure. I put it off for years. The weather here is up and down. 73 on Friday and 40 on Saturday :-)
Glad to see the old machine getting the job done, its always nice to wake from sleep and have some Mr Pete in the morning.
👍👍
9:03 camera angle & focus was fantastic! TY!
Thanks Mr. Pete. I appreciate all of the various camera angles while cutting the part. I know it is a pain to move the camera around.
Thank you very much, you’re right it is a pain in the neck. I’m glad someone noticed
Great Video ,I Have Made A Couple Thousand Racks This Way ,No Read Out Needed ,Used To Build Rack And Pinion Steering Boxes ,Built A Fixture ,To Hold Eight Pieces ,Mounted A Piece Of Purchased Rack To The Fixture ,Then Used A Last Word To Pick Up Each Tooth On The Purchased Rack ,Then Cut Each Tooth ,Move Over .157 ,Repeat ,Then You Don’t Have To Go Nuts, Remembering The .157 Number ,Worked Great Till I Bought A Rack Cutter To Cut Them All At Once ,On A Number 2 ,Browne & Sharpe ,The Good Old Days !!!
Thank you, that is very interesting and a wonderful solution to the task
Thanks for sharing! It's good to see your horizontal Mill again.
👍
8:28 Well isn’t that just the cutest thing in the world
At that angle it looks like it is a robot
Just thinking the exact same thing!
I cracked up when i saw that lmbo
Enjoyable as always. Look forward to my Saturday coffee with Mr Pete. Thanks!
Thanks
Thanks for the video! Keep ‘EM coming!
All your videos are so easy to follow along with! Thank you!
Great rack teach. Lol . Good series Lyle enjoining the way to gears. Been a long time since my vokie days but we had it good many machines in two shops. Machining n then tool & die technology. We built a gear box with slip type change gearing . But great learning 15 - 17 years old.thanks for renewing my memories.
I've cut dozens of rack and pinion gears. I always used a dial indicator to make sure there was no runout on the arbor. That's important.
Thank you for posting another great video.
👍
Thanks Lyle. Stay safe
Thank you as always for the fine teaching and the effort you make in these quality productions!
Many thanks!
Thank You Mr Pete.
Thanks for sharing, I really enjoy horizontal mill videos! Stay safe.
Thanks
Hello Mr. Pete, I learn everyday when I watch you excellent videos. Cheers from Quebec city Canada.
Thanks
Thanks for posting this, I'm learning how to use my horizontal mill by watching your videos.
👍
Thank you Lyle, I learned something new!
I'm amazed you got that spindly little arbor running as good as you did !
THANK YOU...for sharing. Watched and very much enjoyed.
Thanks
Thanks for doing this series Mr Pete, fascinating stuff. I just love watching your horizontal mill, whatever work you are doing on it. I guess that you could also use the shaper to cut a rack, assuming you had the patience as it would probably take about a week to cut a rack that size 🙂
Thanks for keeping up the edutainment while we're stuck inside!
Maybe think about it in this way. How would you hold a straight razor as you shave your face
Brilliant job. 👏🏻👍
Always enjoy your videos keep them coming
👍
Great video! Always great content! Thank you!.
Thanks
Sitting here sick and watching videos and wanting a manual mill to play with, but next big buy has to be a sawmill so it will have to wait. The ding you talked about is tooth 6 counting from the right. Even with that, on a manual machine I would be ecstatic about the results.
Good video.
I am so inclined to ring the bell and I did. Out doing chores today and practicing what you preached. Look forward to the gear episode. Thank you.
Thanks
Good morning Mr. Pete, Nice job on gear. Can't wait for next installment. Coffee time now.
👍
The only parts i made on that horz. mill was bad parts...never got the hang of it, yours are perfect nice work !!
Thanks
Great vidjeo as usual Mr Pete. The old Videos will be very welcome, that way i wont have the trouble of going back to watch them, lol. Big thumbs up and take care, we want to keep seeing your videos for a long long time.
Not much longer, I’m getting too old
Enjoyed thanks for the video.
How is the weather in Texas?
@@mrpete222 sort of crazy. One day is nice and warm in the mid to lower 70's and then back to the 60's the next. Yesterday was short sleeve spring perfect today is 62 in the afternoon.
Years ago when I was young & foolish(er) I made 20 off 3' long by 1"sq. racks & matching pinions for dumpster sliding hatches.... not exactly precision work 🙄😂
I used my Elliot shaper & hand-ground a piece of 3/4" HSS ... using an original rack as a template... (the end teeth with no wear )...
The M.S. pinions were milled on my Van Norman mill using a homemade dividing head. The racks were marked out for each tooth ... I'm not sure if any REAL profit was made on this job but they worked fine and I enjoyed the challange.
As a self-taught machinist from textbooks (no youtube back then 🙄) I learned "on the job" making tools & accessories for my machines. I limited my self to jobs not requiring super precision as I couldnt afford accurate machines & much in the way of metrology... a few mics & verniers ... but I "got 'er done"for a lotta farmers with broken stuff & made a living. I ended up being self-employed for 35 years & loved every minute of it. I was born with machining in my blood...& I still do it !!
😎👍☘🍺
You were very inventive and creative, thanks that’s a good story
They have the Oscars, the Emmy's, People Choice Award, but no You Tube Shop School Teach awards, darn!
👍👍
"Arbor not running as true as I hoped for."
In my experience, even commercially made ones seldom run true.
You are so right, there always seems to be a little bit of a lope In the cutters. I first noticed that 45 years ago
@@mrpete222 It wouldn't be so bad, if you could index the cutter to present different teeth at the high point of the run-out, but with an arbor running out of true, most of the teeth do no work, meaning only a few go blunt, and you throw away a cutter with 90%+ of the teeth still sharp.
@@BedsitBob if the cutter gets removed often enough it couldn't be remounted too consistantly..
Is this a tool that stays on the machine long term?
Just thinkin..
I guess thats irrelevant if the arbor is where the error is...
@@imagineaworld The cutter will always be mounted consistently, with the same tooth running high, because the cutter is keyed onto the arbor, so is always fitted in exactly the same position.
I like it!
Thanks
Lyle just for fun if you want something else to do. How about a single point tool and do it on your shaper ?
Just saw your comment Dave ... after posting my comment about doing just that !! ... 30 years ago ... the racks I made were 3 FEET long !! 😂😂😂
I think I grew a couple of grey hairs on that job .... even tho I was only in my 20's ... 😂
😎👍☘🍺
I always enjoy your videos. M
Thanks
nice!
Thanks
Woo another Mrpete222 vid! I heard of you through This Old Tony and I love your stuff!
Thank you, he’s a good guy
@@mrpete222 I'm loving your channel. I watched all 10 of the Floatlock Vise videos in one sitting and I was impressed! I'm in school for Drafting/CAD right now and I'll be graduating soon. Maybe one day I'll send some prints your way haha
I doint know how but every time i start a project you .upload a video about this .👍Many thanks from Spain
Hope you and your Family are Virus free. Take Care and Stay Safe. I am in Australia.
@@daveticehurst4191 thanks me and family are well .at home for 10 days now.
Still 2 weeks to go. totall lock down
Be care full god bless you .Best regards
That vise really takes up a lot of room on that mill table! Seeing that rack cover that whole Bridgeport table was really amusing. Totally the other end of the scale of what I usually work on.
You could make a rack 12 in.² and 10 feet long
Only one like allowed. :(
I imagine that climb milling on that job could be disastrous!
Great stuff Mr. Pete, thanks again for sharing!
Yes
Very enjoyable video Mr. Pete. I think your arbor is beautifully made. I think I'm sometimes overly critical of myself too, because I just can't like when I have Bubba moments.
lol
I love you man 🥰
I see you invested in Dr. Farnsworths FingLonger device.
Must be a bad moon arising, because I have seen rack-age and ruin? Cheers Lyle, stay healthy!
Nice video. Thanks for making these videos. Don’t know if you own a metal shaper, but if you did you could make a rack of practically any length, just grind a tool bit with the proper tooth form. Also, for those viewers who might need a rack and/or pinion, www.mcmaster.com has a nice selection. I remember running the horizontal mill in high school machine shop class 1973-1975, think it was a decent size Milwaukee.
Mr. Pete - we (at least I) would love to hear your machine doing it work, we could always turn it down if too loud - just sayin'. Anyone else-?
When I speed a video up to 2x, The sound is automatically deleted
Seems like a shaper would be a good choice for a large rack
Great way to start Saturday morning - can't go anywhere, anyway. Hope you are well.
This seems obvious but do you use the same cutter to make the pinion?
No
Looks like you could paint a couple eyebrows on the clausing's over arm support. Good video.
I had thought about that, and I might do it someday
How would you go about making features that let you assemble multiple small racks into a longer one?
🔧😊👍
Hard to tell , but with smaller dia. arbor , might it be deflection ?
Could you increase the maximum width of cut by moving the cutter on the arbour? or would you lose some accuracy.
Nice job on the horizontal mill. Could the shaper be used for a longer rack? Obviously it would take quite a while. Thank's for the great video.
Yes, provided the parts of the machine clear the work-piece.
Indeed, a longer rack could also be cut on the horizontal mill, provided the machine parts (eg. the overarm support) clear the work-piece.
To that end, larger diameter cutters (the larger the better) would help.
Absolutely yes, as long as you need. As far as time wise, we have a time punch card clock !
Should have been climb milling imho!
how would you cut the pinion on the horizontal mill. ? [for the benefit of doubt & them that have never. cut one on such a mill]. les show us. please. thank you.
I just have to wonder ... could you do double rack and would it provide more stability or would it bind up easier ?? Something I'm going to try when I run out of other projects.
If I get corona virus can someone tell me where to get lime disease because I can’t have a corona without lime 😜
You actually have my wife and I cracked up. That’s the best thing I’ve heard all day
What procedure do you use to set up the arbor to run true? I’m having some problems getting my Bridgeport arbor to run true. No wobble.
Where can I get a little aluminum mill like that 😊
Give me a double rack , extra sauce ....lol
Are usually order a half rack
Anyone know if that style of gear indicator gauge is available in north America at a reasonable price? The leaf style that seems to be available are far over priced for me.
that mill looks like walle
Looks like a lot of radial runout on that shaft, mrpete. I’m supposing radial isn’t critical, but excessive axial runout will widen the dimension between teeth?
Umm, did that intro screen say "Horisontal"?
Good video as always :)
Whoops
en.wiktionary.org/wiki/horisontal
Mr. Pete, why don't you just use the shaper to cut the rack? It would seem ideal to eliminate the clearance issues you show with the horizontal and vertical mills.
I may try it someday. My Shepherd is too low powered. It’s stalls on a plunge cut
Did this video have huge gaps of silence?
Mr Pete, I don’t have a right angle attachment. Would adjusting the head on my mill 90degrees work for this kind of job?
It might, but the big head might get in the way. Go ahead and tilt it and you’ll see what I mean
Looks like you're climb milling. Or maybe the video is playing tricks on me. Isn't it better to be cutting down, into the vise for heavy cuts? In any case, thanks for posting the videos about the horizontal mills.
I'm not a machinist, so sorry if this is a dumb question. Would it be possible to do twice the length by using a piece of stock double the length and turning it round?
Yes, if you actually mean double the width
For us non-machinist, how do you tell which direction the cutter should run?
You can cut left to right or right to left depending on which way round you install the cutter. Obviously if you cut the other direction the cutter has to rotate the other way too. If the cutter rotates the wrong way, it won't cut and the sound of it will tell you something's wrong pretty quick.
Sometimes things strike me funny. I was looking at your oil can on your horizontal mill. I thought it said Tubalcan. Could that be so?
Use that rack to make an arbor press
are you going to make something with these parts?
Yes, watch for it
The problem with A rack is there is no exit stratagey
lol
Something just occurred to me. Is it possible that after cutting something like this that warping/twisting/bowing could pop up? And if so is it likely to even be enough to be any problem for more precise tolerances?
That was a big problem years ago at school. But I checked one of these little racks with my brown and sharp straight edge. I could not detect any bowing
It happened to me when I cut a new rack for the surface grinder I'm restoring. 1 inch cold rolled, 14" long, 12DP teeth cut one side only. It bent about 50 thou. I had no choice but to remake it but using hot rolled stock.
@@ThePottingShedWorkshop you couldn't straighten it? Just a question. The commercial rack i used in the weld shop was never straight
Hi Mrpete, can you stack the racks in a line to make longer ones? how to do that ?
Mark, YES you can, often lathe carriage racks are done this way. You would have to ensure that the end of each rack is accurately machined square and the distance from the end to a tooth is 1/2 a pitch, so that when they are joined together, the pitch is correct. You would also be advised to Dowel each piece of rack down to where you intend to use it so that any force from the pinion does not try to push adjacent rack parts apart and give you binding.
Of course it is still preferred to use a continuous one, on the lathe I have the rack has 2 pieces, the other piece is in the bed gap piece and the rest 1,5m is continuous.
Freeze this video at 8:32 and try to convince me the mill does not look like a surprised alien robot. . .
Maybe I was fooled by different camera locations, but were all the teeth cut in the same direction?
Yes
I need a new toy
I love cutting gears.
It's interesting that for both DP (imperial) and metric gears there are 8 cutters to the set, that do the same number of teeth range, but the cutters are numbered in the reverse order.
I miss not having a universal mill to be able to cut helical gears, other than plunge cutting them to fit a worm drive.
With only a 5/8" shaft, if any of the spacers are not perfectly parallel on the ends it will bend heavier shafts when tightened up.
Do you have a keyway in the shaft, that would further reduce its strength, even if it was only 4 mm or so.
My key, just a little hardened pin
The daimetral pitch is almost the same as the metric module pitch. I was just figuring out the pitch of a couple metric gears that I need whenTubalcain started this series. I found the conversion in the same Brown & Sharpe catalog that Mr.Pete has on page 336. A module 1.25 = 20.32 daimetral pitch. It turns out that the depth of cut between a 1.25 or 20 DP are only a couple of thousands different. I found this interesting anyway. Yes I lead an exciting life!
@@andyZ3500s The mathematics for metric module gears is simpler than initial DP.
For metric module:
PCD = module # x number of teeth,
OD = PCD + 2×module #
Depth of cut = 2.25 × module #
With imperial gears DOC varies with pressure angle and reference standard.
Do arbors ever run true? I have Cincinnati, Kearney and Trecker, Brown and Sharpe, etc and I don't think ANY of them run perfectly true.. Cheers! Mike in Louisiana (Ramsay 1)
I’m glad you asked that. I never had an arbor on my milling machines at school that ran true
Great little public domain animated GIF showing a pinion acting on an endless rack here: en.wikipedia.org/wiki/Pinion#/media/File:Rack_and_pinion_animation.gif
Thanks, I will check it out
At 5:30, video goes silent.
Mr Pete thanks yesterday I made my first Percision
Tool I made a optical punch set so thanks for your videos and what you do
👍👍
Is this still considered hobbing, Lyle?
No
Well now that we know how to make a rack when are you going to show how to make a ran?
🇺🇸
But I wish you were my teacher.
But I was a very bad pupil.
My metal work teacher. Sed mop up that water by the forge.
So I did with the oxiocetilin torch.
I know that's not how you spell oxiocetilin.
For all my hard work. I got a smack on the back of my head. Mmm
When I left school. I worked in a tool making shop. 50 years ago. But all I wanted to do was to punch my manager.
So I left.
Better than going to jail.
But now I miss metalworking. M
Yes, I had a lot of kids like you at school. But some of them liked being in the shop. And they sure liked it a lot better than being in math or English, LOL. And actually, some of them were really nice kids, they just needed a little growing up
