DIY Cycloidal Gear Cutter: Part 4 Making the Lantern Pinion

[@antstephenson9497]

Nice work well done, I need to get busy.

[@JourneymanRandy]

All that in under 9 minutes, wow. Thanks. Nice work

[@robertt-cs8fe]

Thanks...I did speed it up a bit...kinda like a Benny Hill episode (:

[@ActiveAtom]

I am not new to you Tube machinist videos but I am new to your channel, you do nice work, as fellow micro machinists we are happy to watch your videos also the time you shrink your videos to makes them really nice to watch, I am glad I found your channel.

[@robertt-cs8fe]

Tnx guys...I've been enjoying your channel as well...keep posted...next week new video on cutting the escape wheels and making the collet.

[@AdventureswithaVerySmallLathe]

Thanks! I learned a lot from this video, and really enjoyed watching it!

[@robertt-cs8fe]

Thanks a lot...I just looked over your channel and subscribed...I look forward to start watching your stuff later tonight!

[@samcoote9653]

Ohhhh funny seeing you here AwaVSL :) hope that chinese lathe isnt posing too much trouble!

Very good videos and informative. I have 2 questions with a problem I have been having and that is when you used lighter fluid to clean up the loctite on the lantern pinion how is it not breaking down the loctite and causing a week point. And when you took it to the belt sander to grind off the remainder of the pins how does the heat generated then not break the loctite down. I have done some projects lately where I have had problems with booth. Heat and cleaning up breaking the loctite down and not holding. With that being said I used loctite 638 high strength. Any help on these 2 problems I have been having would be greatly appreciated. Thanks and keep up the good videos.

[@robertt-cs8fe]

Anthony thanks for asking...the green Loctite is like plastic when it cures...using lighter fluid does not get into the press fit where Loctite is holding trundles...just the overflow...and most times I still have to go in the next day with a dental pick and clear Loctite from the edge of the trundles. When I clear the end of the pinion on the sander I peck at the sander carefully not to heat the trundles much...it only requires a couple of seconds to do the job...go slow and be aware of the heat...bob

عالی بود تجربتون.ممنون

[@robertt-cs8fe]

Thanks Karo

[@1pilotsteve]

I think the trundles are supposed to be free to spin.. See James Martin YT channel.. Nice job sir..Steve

[@jessestrum]

hi bob what did you form the taper with for you collet blocks is it 30 deg thanks for all your work on the videos cheers john

[@6NBERLS]

Most excellent.

[@robertt-cs8fe]

Thanks a lot...bob

[@pgs8597]

Quite fiddly work, well done. Cheers Peter

[@robertt-cs8fe]

G'day Peter...Thanks a lot...it is just a bit fiddly, but it's fun too...Cheers

[@mainarbor8416]

Hello, great video! I am a Horologist. Please forgive me for saying so but your trundles are supposed to be able to rotate individually. This ability reduces friction.

[@mainarbor8416]

@Craig I don't know the actual answer to that other than the ease of making them and old technology. Modern clocks use modern spur pinions. Another guess is the rarity and cost of steel in the early American days. Side note the rarity of steele for springs is why antique American clocks were weight driven.

[@mainarbor8416]

@Craig also the technique to retain the trundles is to put crows feet in around the outside of the hole the trundles are in.

[@georgeblack589]

Really? The only trundles I've seen spin are ones where the entire assembly was coming apart and waiting to fail. Nearly all the American clocks I've worked on had them staked in place. What kind of clocks have you seen with rotating trundles?

[@mainarbor8416]

@@georgeblack589 I've seen the same clocks as you. Next time you see some look at the wear pattern on those who havent been fixed into place compared some that have been fixed.

[@georgeblack589]

@@mainarbor8416 I'm not arguing with you, I've seen the worn teeth and deeply grooved trundles, I'm asking which ones tended to have them rotate. The average American mantle clock was made for economy, so I figured you've seen something much nicer and had some insight. To be fair, I don't think you've seen the same clocks as me, unless you live in my part of Colorado and work on the tower and street clocks there.

[@RPMechanics]

Very well done. You do awesome work.

[@robertt-cs8fe]

Thanks a lot

[@brianwarburton4482]

Thanks for the video. Very informative and well presented as usual.

[@robertt-cs8fe]

Thanks a lot

[@TheJohndeere466]

im a machinist but know nothing about clocks but why cant you use involute gears for a clock

[@thebaron44]

Looks good ...almost traditional...too bad you used Loctite

[@carlspencer4024]

Been restoring antique clock works for quite some time an am having a problem understanding the reason for putting in trundles in the lantern with locktite. I have never experienced trundles that didn't float. the crud may need to be cleaned out or just unstuck. as one of the best clock repair authors said "quote" putting a trundle in with glue or solder is not professional and makes it very hard for the next repairman to make a trundle repair.

[@gispel7058]

Yes. A clock lantern pin in many cases does float. It can be captured within the lantern housing useing a cap or by stakeing the holes. I have seen both in the 45 years that I have making a living at clock repair. Dont think the masters used locktite in 1870. Good machine work though.

[@phobos977]

works like a clock,

[@robertt-cs8fe]

OMG maybe someday it will tell time! Tnx Bob

[@jimmyhawkins7696]

Do you make clocks as a business. Im starting in as a hobby myself.
