Thanks to DSloop's idea, and seeing pics of the Consew 226B lift arm which has a similar bearing on the end, my dad and I decided to make our own. I included some pics of the machining process for those interested. Seems to work well. 

Also added its own tire on the wheel 

Mine looks like crap now.  Too bad I don't have a machine shop.

 Not at all, Yours is still a simple, elegant solution my friend. 

I kinda wish I had made it wider now and put a real bearing in it. I think the larger surface area as seen in the posts above when rolling helps it out.

Bobbin tension kinda stays the same unless you go from light to very heavy thread. Did you set it where the thread is resisting being pulled from the holder? It should not be loose, but offer good resistance.

Check ALL of the guides and little holes where the thread runs thru.If there is even a small groove for the thread to catch it will mess everything up. Get a good magnifying glass and check those out, along with the tension discs. I don't run the thread thru the small guide at the foot, it runs just fine with out going thru it.

I adjust the part in image 4 so it lets the thread thru freely, it don't require a lot of attention. (I think).

Remove the take up discs off as a pair, but leave the spring on the machine.

Wind the thread take up spring around clockwise 1 turn then put the discs back on. This can be a pain, make sure you don't trap the little spring with the discs, there is a shoulder back there for it .

Good luck.

How do you adjust the bobbin tension?

How exactly do you adjust the bobbin tension ?

There is 2 small screws holding tensioner to bobbin case. Tensioner is basicallly flat metal piece. When thread goes between this plate and bobbin case - it rubs creating tension. You need to adjust using center screw in very small 1/4 increments. Opening - will open gap decreasing tension, closing - will close gap increasing tension. You need to rotate hook in a position where you see those screws on a side.

You should feel tension when pulling bottom thread. And you should feel difference after making adjustments. Sorry, I can't find any pictures

That does not need to be adjusted unless you go from a large diameter thread to a very small one. Usually. Top thread tension seems to regulate the bobbin thread tension good enough.

It appears the tension spring is missing.

thank you for the responses
