I finally got around to putting my Mark VII back together and this replacement idler shaft is working fantastically! Thanks again for the fantastic work making this new design of shaft. Haven't used the machine with anything attached yet, so I'll provide updates if anything goes awry with this shaft...

Wow! Can’t wait to get my parts out to you Mike!

JPG, what were the eclips you sent him? I have two different sizes which doesn’t exactly make sense and one is beat up.

The control sheave bearing seems to have some wobble in it with the part that comes out the end. Is it normal? Bearing seems to spin fine besides that. Probably a non-issue since it’s held in place by the nylon speed controller part. I’ll check with Motion with the info provided to see what they can...

I need to order new bearings to go into the eccentric so I can send Mike the parts he needs and the ones in there now are KOYO S375Z bearings. These appear to be no longer made. Does anyone know a suitable substitution? While I'm at it, I'm going to try and replace all my bearings because... why not...

The threads seem skippable if you can retain everything like the Mark V does. Not sure what the secret is (if there is any). I'm in talks now with Mike to give this a go.

Miken, if you think it'd be easier to simply remake this shaft, I do think it's the better option. Sounds like you have the tools necessary to make this happen. I'll send you a PM.

Yeah, adapting it to a Mark V speed controller setup crossed my mind when I found that post. I'll have to pull the idler shaft out of my Mark V and see just how different they are. It seems like a new (used) Mark VII idler shaft would be ideal but I've not found a source for one yet. If I had a meta...

I'm rehabbing a Mark VII unit I purchased recently and one of the issues I found was that the idler shaft that holds the eccentric bearing had a lot of play in it. Disassembling it I found the shaft has worn away from where the bearing is supposed to ride. Idler Shaft Bearing Surface.jpg Does anyone...

Oh, I’m working on the Forward/Stop/Reverse switch at the moment. Though I think the bearings in the motor could use a replacement. I’ll post a video here when I have a chance to get y’all’s opinion on that. I could be overthinking that one. I carefully pulled the cover off the switch and was able t...

Okay, so the case and the male connectors aren’t attached to each other directly? It looked like the connectors were sort of pressed into the case. I have not noticed any screws that can be removed besides the one that holds the lightbulb post. I was thinking about graphite or something similar too ...
