Does anyone roughen up the edge and clean it up with denature alcohol to help with the bonding? I saw a video from boardcrafter that he roughen the edge and clean with denature alchohol.
I usually wipe them down thoroughly with a cloth. If there's any corrosion I'll lightly sand and wipe down. I try not to use any chemicals unless absolutely necessary.
My edges from skilab were sandblasted and rusty. Rather than sand blast them again (I have a blaster) I wire brushed them with a wire brush cup attachment on the grinder and then hit the tangs with a flap disc 40 grit to rough them up.
I dont like a sandblasted finish because it is actually impregnated with tiny pieces of garnet.
I have garnet in my sandblaster that what I was talking about. I wire brushed to remove the rust and then used a flap disc to rough up the tangs so they bond better.
Thank everyone for the Reply. I have some rust on the edge. So I would have to sand some down. Another Question : I use Hot Glue to keep my core down while using planer to profile. after I use the Hair dryer to soften up the glue to take off. but there still some sticky left. How do you complete clean of the hot glue? I read that isopropyl alcohol can be use to remove the glue. What your method of removing the hot glue after profiling?
I put some Hot glue under the core and around the perimeter . It definitely stick on really good. Had a hard time getting it off under the core that why I heat it up to make it easier
I've always just cleaned the rust off with methylated spirits. Seems to bond fine. I vaguely remember reading or someone referring to a test someone did with bonding rusted edges and they found the rust actually helped pit the surface and improved bond (as long as you clean the powdered rust off).
