Topic tags/keywords: resource tip question trick pine douglas fir carving tool angle grinder carbide rasp carving shaping sanding rustic arts and crafts

Not sure if this is the right forum in which to ask this question, but didn’t see much else that might be applicable. So, here goes.

I’ve been working on two fireplace mantel columns made from Douglas Fir root balls that have aged and weathered over the years.

In trying to get down to bare wood, I’ve been using my angle grinder with a 4 1/2” carbide rasp wheel I bought at Harbor Freight. It works really well on most woods, but I’m finding that the resin build up on this type of work and wood is beyond anything I’ve had to deal with previously.

I’ve used wire wheels on my drill to try and remove the resin with limited success.

My question to those LJ’ers in the know is whether there’s something else I might be able to use to get more of the resin off? This stuff is nasty!!! At certain points, the resin actually starts to smoke as it builds up due to friction and heating.

Thanks, in advance.

Thanks, guys, for the advice. I tried oven cleaner first, and am probably not going to have to go any farther than that (see photo below).

A couple hours in a “bath” of oven cleaner really did a nice job with minimal wire brushing to take the final little bit of residue off.

This grinding wheel is about at the end of its life, but I don’t want to throw it until after I’ve got the rough grinding done on the fireplace mantel columns I’m currently working on.

Thanks, again.

soak it in acetone .. for blades and bits try Krud kutter .. Lowes sells it .. works great .. but resin is different .. naphtha will also remove it just not as fast, resin you have to dissolve

Citrus degreaser like Zep will dissolve it quickly. It’ll clean a saw blade in about 60 seconds, might take a bit more for that amount of resin.
