Hi everyone!

My name is Loren, and I'm from south central Wisconsin. I recently purchased a 1979 SS Mark V from a guy on Craigslist. Cosmetically it's in really good shape, and it came with quite a few accessories. Unfortunately, it runs fairly rough and is noisy. I'm comparing it to my Dad's late 80s Mark V. I've been browsing this forum and soaking up all of the awesome info on here. I think I could spend a couple of days filling my brain with all things ShopSmith.

I will be spending most of my time in the Maintenance/Repair forum, as I would like to give it a complete cleaning and lube. I think the speed control is a little damaged, as it wobbles a little bit with every revolution of the control sheave. I also think I have a siezed bearing on the idler shaft; I can't see it moving when the shaft is rotating. :/

I plan to watch the Sawdust Sessions on "Shopsmith Reborn", as it seems to cover the kind of work I need to do on my machine. I've already learned about the little burr that can happen on the shaft for the speed control, and my machine has it. I think I will be busy for a while! Any tips/tricks/suggestions would be much appreciated.

Loren

Welcome to the family, Loren. Once you get the M5 up to spec's it will last you for years to come. And hopefully provide you with some equipment you don't already have.

I'm in Hartland, WI and have resurrected one to usefulness and am now eyeing it to go to the "MickyD Standard". I'm just a little concerned that will lead to a new hobby of metal polishing.

If you need a extra set of hands, hopefully I'm near enough.

Oh, and put up pictures. Everyone hear LOVES pictures.

Welcome to the group. I have found people here to be very helpful and glad to point me in the right direction when I hit a rough spot. I'm sure it will be the same for you.

Pictures are worth tons in trouble shooting issues and finding solutions so I will reiterate that posting pictures is a good thing:D .

Have fun and feel free to ask for direction. Just be aware that a search my yield a lot of answers before the questions get asked.

I am not sure what you expect to see rotating on the idler shaft! The nudging (wobble) of the bearing which butts up against the speed control quadrant arm MAY be caused by the belt(s) varying width. You really need to take the motor belt off, the speed control 'out' and remove the 'control' sheave pulley half. From this state of disassembly you should be able to determine what if anything needs replacement/adjustment. You will also learn MUCH regarding how this beast 'works' and what can cause it to 'complain'!

Thanks for the welcome, tips, and offer of help; it's much appreciated. I'm well aware of the search function, and plan to use it often. This forum really reminds me of the Suzuki M50 (motorcycle) forum I found - a wealth of knowledge and great people; everyone there is always reminding everyone of the search function.

I plan to take pictures to assist where my words fail. I want to get acquainted with the inner workings of my machine before I start tearing it down myself, but that is one part I am excited about.

Thanks again!

Loren

Well I couldn't resist... After watching the first half of the teardown video during my lunch break, I removed my speed control and the idler shaft. I don't have the headstock removed from the base, and I wasn't able to pull the shaft out of the headstock (is it possible to remove with the headstock still on?).

There is a lot of wear on the speed control quadrant and on the bearing that the quadrant pushes on. In fact, that bearing looks... destroyed. I'm sorry, I'm probably not describing it correctly, but pictures will follow, hopefully when I get home tonight.

The good news is that after removing the speed control, most of the noise I heard has gone away.

The motor belt needs to come out first b4 the control sheave can come off the idler shaft. Then the idler shaft can be removed(from the outside) AND ALL the screws etc. holding it 'in'. Do NOT overlook the set screw holding the bearing in the eccentric collar! The eccentric collar should be rotated to relieve pressure on the poly-v belt. ALL This needs to occur, not it the order stated here! Be patient. If it doesnt move or 'gets caught', just look to determine WHY? If you cannot tell, HOLLER!
