ShopSmith owner of 50 years with some comments . . . .

Y'all remember MickyD referring to 'the gentleman wearing a trench coat' who was wearing a shop 'coat'.

And those turn of the century(no not the last one) pictures showing workers wearing Sunday go to meeting clothes in a furniture factory?

Times have changed. IMHO mostly for the better.

I agree in some JPG, but when I go out to dinner at a nice restaurant on a Saturday night, and I got a guy sitting at the table next to me with a baseball cap on, and some sloppy slogan T shirt on in blue jeans, where is the eloginst??
Agree we dont have to dress up to work in a factory.
I know this a bit extreme, at least up here in WI, but I am sure very common in Wild Cat Country.

ERLover: Besides not being related at all to any Shopsmith discussion...I really do not understand why you would post trash like this to the forum.

Welcome to the forum, Jacob! Wow! your first post was yesterday evening and already we are on page three!

Your name has been mentioned many times on this forum - In a good way! Your ability to repair Shopsmiths has been mentioned as one of the very best places to go in Southern CA.

As a hero (you probably don't realize your fame) of Shopsmith knowledge, You are VERY WELCOME to this forum.

Well, thank you Charlese for those nice comments. However, I am not the Jacob you refer to. I live in the San Francisco Bay Area and don't do repairs of ShopSmith machines (commercially).
That is not to say that I couldn't, with all the extra parts I have. Take a look at all the new bearings I have and tons of other spare parts.

I mentioned that many of the items were not made by Magna (or the other companies since). The tag on one of the belts in the picture says 'Matched Set by Gates Belts". Gates is still in the business of making belts.

Would it be possible to tell from some of these bearings who the various OEM's were for them back then? Some of the more experienced here know far more in that arena than I do, but I know my oldest Mark 5 that is an early A Series Chassis has bearings that have lasted and are still functional today. Most of that I am certain is aided by proper maintenance and cleaning through the years preventing things that would tend to deteriorate them.

Thanks for your willingness to share and post, and welcome home to the forums here. I hope you find it as rewarding as I have. There is great wisdom, experience and patience here that I trust. I know we are all glad you have joined us.

On older parts (bearings and others) that are marked with manufacturers numbers, it would be "possible" to determine the OEM, however, that would require documentation that you and I do not have. That documentation may even be "trade secret" now. I have been away from the manufacturing floor for far too long to know.

This number, 205KDD6, is the Fahnir number for the 10ER spindle bearings. SKF might mark that bearing either 88016 or G88016.

The bearings I showed in the picture above are predominantly from Fafnir (although there are three from Norma Hoffmann, same size as the 29 I have from Fafnir).

Some are in the original boxes (wrapped in wax paper) and have serial numbers that I can give you if you are really interested. In addition I have the ID, OD and width for the five different sizes.
I do not know where each of them were used on the ShopSmith.

I am sure Shopsmith knows where they now come from and where they are used. So, ask them.

I totally agree Dusty. However lots of manufacturers put their name as well as a P/N on the bearing. Also from what I have seen each manufacturer has their own numbering convention that they use so it might be possible in some cases to figure out who the OEM is from the way the P/N is constructed. Fafnir for one imparts a lot of the bearing properties in the P/N if you know the code. You can get that information on the Timken/Fafnir web site.

Just to avoid confusion in the future the bearings for the 10ER spindle/quill are indeed Fafnir but the P/N is 202KLL3 and not 205KDD6.

Perhaps I missed something about what Dusty said.
When bearings have a serial or part number marked on the race and you know who made them, I cannot see how buying the bearings again (or from another vendor) would constitute a violation of a 'trade secret'.

It would, perhaps, be different if I were to take the engineering drawings I have of all or most of the ShopSmith parts and started to manufacture and sell them.

BTW I found it interesting that two out of the five bearing sizes were metric (the others were in inches). I wonder if that was a carry over from the inventor Dr. Hans Goldschmidt. The large bearings, for example, measure 25mm ID x 52mm OD.

Dusty was talking about the documentaion connected to the P/N which would identify the OEM. That would be the print for the part and that is proprietary usually. The print number is usually the same as the P/N. That is what we don't have access to.

[dusty]

I do believe that "metric" is more or less standard for the mechanical world. Especially for precision measurements.

Here is a little trick that my father-in-law used.
He welded a handle on a allen-head wrench. That made it nice to hold and he could hang it on the front edge of the table.
I made one a couple years ago with a wooden dowel. I milled a slot half way down the length of the dowel and epoxied the wrench inside of that. Of course, I lost it somewhere and should make another one.

Sorry about the camera angle. The welded part is really square with the rest.

JS that maybe true a lot of times, but there are engineering drawings that specify the components to be used, but not necessarily the manufacturer. That prevents the engineer (or draftsman) from getting involved with procurement and possible sole-source situations.
I'll take a look to see what Magna did with their drawings.

Nevertheless, the part number on bearings are not necessarily the same as the part they go into.
