Hey Wayne, when this happens to me (for the same reasons), I usually do what you did.

I basically use a scraper on the blade, except I spin the top wheel by hand. Main thing is to avoid hitting any of the teeth, otherwise its no big deal and you wont be harming the blade.

For the bearings, I usually use a razor blade and spin the bearing by hand. The razors finer edge seems to do a better job at scraping the polished bearing surface (which really seems to stick well to wood gunk).

For prevention, there are a number of things you can put on the blade/bearings to reduce/eliminate sticking. Use non-silicone based lubes if you are cutting veneers or otherwise worried about getting some stuff on a surface that will be directly finished, otherwise even WD-40 will help greatly. (non-stick cooking oil spray also works well)

Have ya ever thought about tryin’ a quick spritz of Pam pan spray? I use it when cutting heart pine. Wanna talk about high resin and build up on blades?
In a production mode, some use a soap/water emulsion, but I find that too messy for my small work.
Just a thought.

I replace them frequently. Less than $2/each. Look them up from the bearing number:

PLUS: WD40 or PB-Blaster works well as lubricant.

I started out by turning the wheel by hand backwards, but it took forever. Even when using something with a sharp scraping edge. That gunk is REALLY stuck on there. I realize that doing it with the saw running is not the greatest idea in the world, and probably not for the safety conscious either for that matter. But it is a lot quicker.

For the bearings, that is pretty much all you can do. I finish off with a quick hit with some 320 or higher grit sandpaper.

Cooking spray! That sounds like a winner and I will try that next time.

I just did about 3 seconds ago.

I bought a bunch of new bearings recently, but the bearings don’t go bad when they get gunky. It’s just that the bearings are so close to the blade that when some gunk comes along it gets smooshed HARD into the blade and sticks like I don’t know what to both the bearing surface and of course, the blade. Take the time to clean them up and they are fine until more wet wood comes along.

Thanks for all replies.

Yep, and having spares to rotate in and out of service, makes for a good day every day, IMO! I often use PBBlaster (a solvent lubricant) to clean the bearings. Much better than WD40. Also lightly hitting them with compressed air helps.

I guess I haven’t cut any green wood that has a sticky sap yet because I’ve not seen this problem. Has anyone tried coating the bearings and blade with paste wax or something like Boshield to help prevent the buildup? Just wondering if this would help or if it would have any negative affects.
