Gear cutting. Making gears in the home workshop.

[@SimulationNPC]

I enjoyed watching this process. Thanks for sharing!

[@edsmachine93]

Nice work. I like the super glue trick. Amazing how it held up. Thanks for sharing. Have a great week.

[@MetalMachineShop]

Thanks, the superglue does work well as long as you give it time to set fully and don’t overload/overheat the work.

[@mmnyako]

Gears are amazing. Thank you for sharing!

[@jimsvideos7201]

Speaking of mod 0.6 gears, a set where one has 200 teeth and the other 189 will almost perfectly convert a 1.5 mm pitch leadscrew to 16 TPI or vice versa. At mod 0.6 they'll also more or less fit on the common imported 7" mini-lathes; this is a project I look forward to tackling this winter. Thank you for the video; there's no way to have too much insight into the practice.

[@darryllcrook376]

The exact (not approximate) conversion needs 120 and 127 tooth gears. Why would you cut two gears with a total tooth count 70% higher than this only to achieve an approximation? 86 and 91 work as an approximate pair and the total teeth on the two combined is less than just one of the gears suggested above. If you are feeling lazy, 34 and 36 are good enough.

@@darryllcrook376 good info, Darryll... 😎👍☘️🍺

[@UncleKennysPlace]

Interestingly, I have one such mini-lathe which I just removed (yesterday!) from the shelf, to put back into service. It has an imperial leadscrew, but I most make parts in metric. Then I found a "new in the box" metric leadscrew/half nut/change gear/thread dial conversion set, which I had forgotten about! It will be a dedicated threading machine.

Great video. New to channel...have to start from beginning.. I have only 2 years on the machines , mill and lathe.. folk like you give me motivation.. thanks ..

[@MetalMachineShop]

Thanks, I agree, background music can be annoying!

[@Workshopfriend]

Enjoyed your video - presentation & content. The centre height off the lathe cross-slide for the tailstock seemed a happy coincidence until I realised you had probably also made the dividing head with the same set up.

[@MetalMachineShop]

Yes I did!

[@peterfitzpatrick7032]

If you don't have a milling machine, line boring the dividing head on the lathe saddle is an easy way to get the bores true AND dead-on lathe centre height, which will be useful for milling with a cutter in the lathe chuck... keyways or cross drilling is a simple process then... I made an identical dividing head in this way, I also made 2MT spindle nose collets for milling cutters or "barstock"...the increased rigidity was huge !!... 😎👍☘️🍺

[@BrucePierson]

You have a very well equipped workshop with lots of custom made tools and equipment. You are very well set up for doing what you want to do.

[@MetalMachineShop]

You can never have enough tools but I’ve built up a reasonable collection!

[@BruceBoschek]

Very admirable craftsmanship! Excellent video, too. Thanks very much.

Neat setup. Gears are fun.

[@terjalgame4763]

I once made a gear with an M1 Z 38 module with a diameter of 50 mm, but it was damaged because the module was worn out and why did I get a low score🤣

[@ObixMT]

I enjoyed this video, nice clean gears. I would like to see more on the custom dividing head that you made. It appears relatively simple in design while still quite effective.

[@MetalMachineShop]

I’ll try to make a short video about it at some point,.

[@mickgentry8128]

Brilliant, and Great video cheers

[@MetalMachineShop]

Thanks!

[@Festivejelly]

cool contraption. Looking at the finish on your parts it looks like you have some serious rigidity issues on your lathe. Might be worth checking the bearings and gibs.

[@peterfitzpatrick7032]

Its a Myford Super Seven lathe with an adjustable conical front bearing... I have an ML7 version, they aren't the most rigid of lathes but are popular in small workshops due to their small footprint... 😎👍☘️🍺

[@charlieromeo7663]

Nice work

[@MetalMachineShop]

Thank you! Cheers!

[@GaryPArmstrong]

I like the skills you exhibit. I will follow your creativity. Question: how do you work out what gears to use when finding the odd gear teeth number?

[@MetalMachineShop]

Thanks! Assuming I don’t already have a gear with the same number of teeth, or a multiple thereof, I use a spreadsheet and a bit of trial and error to work it out. Here’s a link to an Excel file calculator on my website. www.amdengineer.com/resources/

[@samimas4343]

Thanks a lot.

[@angelramos-2005]

Great video.I would like to know the diameter and TPI of the threaded part of your Myford lathe spindle.Thank you.

[@MetalMachineShop]

According to Google, the Myford Super 7 lathes have a thread of 1 1/8 in x 12 tpi. The large bore machines have M42.5 x 2mm thread.

[@angelramos-2005]

@@MetalMachineShop Thank you for your answer.My chinese combo import has a spindle about 1 5/8" and 2 mm thread.I was thinking if a Pratt Burnerd chuck might fit since I don´t find chinese type chucks or adaptors any more.I love your videos.ATB.

[@MetalMachineShop]

@@angelramos-2005 you can get adaptors for big to small threads but not vice versa as far as I know.

[@angelramos-2005]

@@MetalMachineShop Thank you.I keep trying

[@gomountaintriking8460]

VERY GOOD! bro is cool😆😆😍

[@Idontdohandles]

Awesome, do yo know any whee that can make a set of steel gears for a RC ClodBuster truck? 32 pitch gears pretty small but in the range of what you were making in this vid.

[@MetalMachineShop]

HPC Gears in UK sells a very large range of gears so you should be able to find something to suit. They can customise gears if you have the budget for it. You can find them online.

[@peterfitzpatrick7032]

Whats the cutting fluid ? ..looks like Rocol RTD.. (Stinky stuff but great for tapping, milling & turning) nice job... I made a dividing head like that many years ago using the Myford banjo... the design was in a book I still have somewhere... I'm running an ML7 myself, couldn't afford the Super Seven at the time...🙄 😎👍☘️🍺

[@MetalMachineShop]

It's drilling and tapping fluid that I got from Machine Mart years ago. Doesn't smell too horrific or maybe I've got used to it! The S7 was second hand but still quite an investment. The gearbox is a great timesaver.

[@peterfitzpatrick7032]

​@@MetalMachineShop yeah, I have the QC gearbox too..also with the metric manual setup gears .😎👍

[@MetalMachineShop]

Nice - mine is imperial, I’d love to have a metric lead screw kit but I just use the nearest imperial TPI and adjust the design on the rare occasions I do screwcutting.

[@peterfitzpatrick7032]

@@MetalMachineShop I left a comment just an hour ago about a downloadable pdf regarding the metric changewheel kit and whats in it... but the comment disappeared (YT probably deleted it because of the link 🙄) google search "haythornthwaite Myford metric changewheels pdf" and it will pop up.. 😎👍☘️🍺

[@johnutting9615]

May I ask a silly question ,how do you determine the diameter of each gear depending on the number of teeth you need ?thanks

[@MetalMachineShop]

You can either do it from look-up tables or by calculation. The gear diameter is normally expressed as the pitch circle diameter which is the effective diameter of the gear. The outer diameter of the gear blank is greater and depends on the gear module (how big the teeth are).

[@gmcevoy]

Hello! Fascinating video! If I may ask, how did you turn that taper so perfectly, at 4:44 ?

[@MetalMachineShop]

I used the lathe's top slide set over at the required angle.

[@gmcevoy]

@@MetalMachineShop Of course. I had the impression you where doing it freehand. Thank you. Your videos are highly interesting, full of tips and tricks I would never have thought of. That superglue trick for example. Quite useful. Keep up the good work! Thanks again, all the best!

[@kieranh2005]

I use a battery drill with a very slow speed and a big socket with cutouts for the spokes of the compound slide handwheel (topslide in USA) to get a smooth feed.

[@MetalMachineShop]

@@gmcevoy I got the superglue trick from the Clickspring channel.
