So I need to remove these components from the blank.  I’ve never had to do anything like this.  What kind of tools do you guys suggest to get it off the blank? Thanks in advance!

What is that ribbed thing made of.  For most materials one can CAREFULLY use a Dremel saw, cut longitudinally part way through, don't touch the blank, then try to split the part off.  Depending on how well it was epoxied on initially, it will be fairly easy to get it all off, or it could be very hard.  Be careful with heat-some heat will soften the epoxy, will never melt it, and if you get the blank too hot, it will fail.  So count more on cutting/sanding/splitting/etc than heating.

Dremel with a cut-off wheel, then pry apart with a flat screwdriver.

Okay thank you

Finally finished the reel seat repair
