C Series Clutch Shaft Frame Bearings

[ri702bill 10,642]

There was a fair amount of wear on the ends of the C81 Clutch Shaft where it goes thru the frame. Metal on metal, no bearings & not easily lubricated.

I installed the bronze bushings on the 502 frame a while back, using the milling machine. The C Series has two sets of welded 3/4" diameter rods to hold the foot rests, the rear ones were in the way - could not do this in the milling machine. There were 3 choices - cut the rear rods off & reweld them later, do the work by hand, or - break out the 1950's ShopSmith 10E and use it.

I went with option #3  - while the assembly & setup are extensive, it gives the best results. Pictures are for the RH bearing: the setup needs to come apart and be reassembled opposite hand to do the left.

nice work!

Looks like you have some nice tools to get the job done. A big

Very nice work here Bill. 

 

That's the type of lathe I'd like to have someday.

Eric, I’m sure if you found one it would be big dollars. But like you said it’d be nice to have one. Enjoy your weekend.

Thanks. Google "ShopSmith" - it is a clever versatile tool. Setup horizontally, it can be a lathe, a horizontal drill, a table saw, or a disc sander. Set up vertically, it is a drill press with a 3 foot throat opening! Later versions modified the tilting saw table to become a small bandsaw too. The three motor speeds as supplied are achieved with stepped pulleys. This application has a larger driven pulley to slow it down... Latest version has a built-in variable speed control. It does a lot, but with compromises... and the components are heavy!

"Big Dollars"?? Maybe not.... this one, although not complete, was FREE - I had to get the Jacobs chuck & key, the 3 quill handles were missing too.

I use it mostly as a vertical drill to touchup small engine valve seats using tapered mounted stones. Works well for that.

If a person is well organized and has limited space the Shop Smith is a good alternative to a well equipped woodworking shop. The biggest drawback is setting everything up for the next operation, can take an hour of setup to do a ten minute job, but it got the job done for you.

@ri702bill  good idea / nice work , always after  any repetitive  problem  , and how to eradicate it , regularly  look at a change , as to  function , needs a tweak ?  or good to go ?  my first thought at looking at your frame ?  perfect time to lay in a frame length  5/16  steel break line ?  tucks right into the upper  inner corner  of  frame , eliminating  a lot of  fuel hose break down debris  , extend out each end of frame , and cap off  ?  then its just a short run from tank  , and to carb with a fuel resistant hose .  BTW  have also experimented with  bronze lube , obviousely  lucas green , but also super lube hydraulic oil . extreme temp range and loading  makes this stay with tough spots , every inch of my cables has super lube as well as a  spring pull assist to close / stop ?  that spring set up assists every move . might also add a  small  perforated  metal  pull point  for that spring assist , your shop set up  is easy to see  a what if  ?  type of experiment , regularly do that , pete

That's a patience struggle for me at times. But I've been learning to invest in my own time instead of bringing work elsewhere  - when it's practical. 

I figure the drive time I've occasionally saved along with whatever learning experience I encounter is a win.

That is what makes it all worth it. Remember, it's a hobby. If you don't finish it today, it'll be waiting there tomorrow.

It's a hobby...yes... but more than that to us here. 

It's our independence. Our acreage management. Our future. 

 

Sometimes we need things done that day and can't wait til the next. Snow plowing to leave the yard for work for example. 

Thats why we keep multiple tractors for different tasks.  

If/when repairs or maintenance is needed we still have a backup. 

 

Having the proper tools and skills has been an absolute game changer for us at times.

I'll add that there Shopsmith system was designed to be primarily a wood working tool.  But with proper tooling, feeds, and speeds, light metal work is possible.  The ridigity of the machine limits the metal working capability.

Agreed. I'm not trying to be a hero and plow thru the frame in one pass. Drilling in progressive small steps - first .531 diameter, then .547, then .562, and .591. Then ream to .625 diameter. All light material removal & small chips.

That is the best way I've found to turn an oval back into a round hole.

And there is always the question of where should the center actually be? Sometimes it matters little and sometimes a lot!

Funny you mention that. Two reasons. While sweeping the bore for the best lineup, the existing hole is elongated. Gotta go slow.

 

The next task is to drill & ream the Axle pivot & spindle holes for bushings. All show elongation of the original bores. One of the spindle holes looks to be centered on one end of the casting - the exit is off center by almost 1/8", partially due to wear - leaving a very thin wall. The plan will be to move the hole away from the thin wall using a boring head in the milling machine to reestablish a round bore

The second time I worked at Brown & Sharpe I was in the Validator Department. First assembling, then calibrating the CMM's.

A lot of folks used a CMM (Coordinate Measuring Machine) to reverse engineer damaged parts when there were no drawings available to repair / remake that part. The CMM program could determine the original center of elongated or wallowed out holes digitally!

I got one of those. I use it mostly for drill press and disc sander. The wife uses it for storage. Lol.

At Bill’s mention, and curious, I did searched CL for ShopSmith in my vicinity. A Mark 5 with only table saw and jointer for $75 and another with “the works” in upgrades asking $6,000.

Then flip it up to the Vertical post position so that things will fall off!!!

So... somewhere between almost worthless and "priceless"... Including a new V belt, I've still got way less than $100 invested in mine.

[ri702bill 10,642]

Got me curious - here's one in nearby CT - a newer version with lots of toys. Under $400... Others nearby priced for even less.

So comparing a Peloton bike or treadmill or ShopSmith as a coat rack/storage system, which is better?! 🤣

It's obvious - the ShopSmith!
