Good job
Thanks for watching!
Thanks for sharing your order of operations. Definitely opened my mind on how to apply precision when needed, and just as importantly, when not needed. 👍😎👍
Thanks for watching. I’ve struggled to know what to show in these videos. I could do lots of setup videos or how yo approach a specific job and things like that, but I was afraid people would find it boring.
Machinist for about 40 years. I wouldn’t have done anything different on this project. If I was worried about concentricity I would turn between centers or run the end you turned for threading in the four jaw. What you did was plenty good enough for this project.
Thanks for the feedback! I mentioned it only because I expected someone to complain about it, so I figured I’d explain it in advance haha…. You know how arguments on the internet go!
I want to do a video soon showing people turning between centers. The first project I ever did was when I was 15 years old and I had to turn between centers for a high school vocational project.
Good times!
Better than new. Good to see you rebuild it better than new and not throw it in the trash even though it was a lower quality Chinese component. This should provide many hours of service to some lucky mini bike or gocart owner. Great video... Joe
The choice really came down to A) Buy another Chinese unit or B) rebuild this one with a stronger shaft and better bearings
I think B was the better choice
Thanks for watching!
Late getting to watch. I have replaced whole chains, that the Pin came from. Love to see you make a set of seal and or bearing drivers. I know this can be bought for cheap, But then that's what we end up with " Cheap " : ) Has always Sir Liked and shared. I am happy to see your channel growing. All my best.
Thank you! I appreciate it! They have some really big mill chain out at the forest products mill nearby. Pretty cool to see the big sprockets and everything
Jeremy good video! It's funny as I searched an hour ago about key seats and then boom your short showed up! I have to cut a key seat on a 3.25" aluminum tube so this was helpful. Thanks!
Wow! What a coincidence. If you want any specific advice, let me know! I have another shaft video where machine both a woodruff keyseat and square keyseat using a lathe milling attachment. Same principle.

@@MaineMachinist I'll check it out! TY
@@MaineMachinist Thanks I think it should be pretty straight forward... Famous last words! I plan to just clamp it to the table using the t-slots to stabilize it. I am planning to indicate it along the X after getting it clamped down. It's only about 2" long so if I'm close it should work well. It's closed on both ends so it's a plunge cut then cut the slot.
@@ScottDube1 sounds like a solid plan! I actually prefer working off the table instead of in a vise for a lot of jobs.
Great videos but was hoping to watch how you actually got the shaft in !
I recently put a new cvt on my bike, and i drilled and tapped a zerk fitting onto the housing so i can grease the shaft and bearings.
It’s amazing to me that they don’t have open bearings in the inside and provide a grease fitting
Hey man good work.
I don’t understand how you made it fit, the bearings have a ID of 17mm but your shaft is at 17.5mm? Are both bearings sitting on the thicker end of the shaft?
Nice. Is the new jackshaft 16mm and uses a 5mm key, or is it 5/8" and uses a 3/16" key?
Some sellers will get you either 16mm or 5/8". It's best to have 5/8" if you plan on a gearing change. Aftermarket sprockets are 5/8" bore and 3/16" key or keyway.
The last torque converter I got the seller had 5/8" jackshaft in the description. I was pissed when it came as a 16mm jackshaft.
