Anyone know if it's possible to make the guide bearings work with a .025 blade? There is an adjustment for tilt, but none I see for blade width.
Any help? .020 blades are not as readily available, compared to .025.

Im not exactly sure what you need. But when I need a guide bearing or bushing I call these guys. http://gobeilco.com

They are in St. Paul MN and have been making and selling them for over 50 years.

My horizontal Rong Fu bs says .020 blades , I’m using .025 blades but my roller guides are a little adjustable and the thicker blades work fine.

One guide bearing on each side is adjustable per the manual that can be found here.

Thanks. When I loosened the guide bolts, and turned the shaft, the bearing didn't seem to move. I'll dig deeper. I was thinking of drilling out the bearing shaft hole, to allow adjustment. .020 blades are hard to find. I would like to use the .025 blade I now have.

It says the roller with out the flange is adjustable. You may have to take it off and clean it up.

I took the bearing shafts out, and the one hole is oversized to allow some adjustment.
I adjusted them as wide as possible, and it still bends the blade.
I don't see anything to do, but, drill the hole s bit more oversized. Sounds drastic, when, somewhere, I read someone said they used .025 blades on their 108.22921.
Wishwas me!

I drilled the holes out for the guide axels and all is good. Went from .43 to .50" Now I can use the .025 blades.
Saw cuts very nice.
