Default Wear time?

To the OP -- brilliant idea! How quickly do they wear. I am long past this point, but still curious for any remaining small area demurring.

Re the Cratex points, I used these too, but found that they wear really quickly.

Default Scotchbrite DIY longevity!

I have had great success with this tool. The first pie piece lasted me both LH/RH Horizontal stab ribs, and still have enough to to the VS. I believe I can make 5-6 pieces per wheel, so one wheel should do all wing ribs as well. I think it is safe to say that I have saved at least 40% of time spent on rib deburring.......

Thanks for sharing! Especially because I planned to do the wing ribs this weekend. Just in time!

Erik how did you cut the pieces out? Did you just use a band saw? I ask because I have tried to cut these for a different reason and they are always tough on things.

Default Cutting scotchbrite wheel

The best way I found to cut the wheel, was to change my bandsaw blade (which comes standard with all purpose blade) to a metal cutting blade. And then just two cuts to the center of the wheel....Wah La !

Cool idea, Erik! How did you shape the Scotch-Brite into a cone?

Thanks!

Thanks!
I have shaped entire scotchbrite wheels (to get rid of grooves) by doing the following which will work in this case too. I put small wheel on die grinder (in this case it will be dremel) then take it to my rotating scotchbrite bench grinder wheel and shape the small one. I make sure they are spinning opposite directions of each other. This works extremely well but definitely make sure you are wearing eye and lung protection as a lot of dust flies! It also did not make any dent what so ever in the big scotchbrite wheel on the bench grinder so you don't have to worry about spending that $78 bucks again.

Perfect timing. I just laid out all the wing ribs yesterday in advance of starting to prepare them, and I might try this method.

This is indeed a great idea. Made my own right after seeing this thread, and using this technique a LOT for all the scalloped fuselage parts. I found the scotchbrite wheel easy to cut with a hacksaw and used the bench grinder and dremel to shape. I go through them fairly quickly... but definitely the right tool for the job.
