That sounds like a great tip, I will try the on the one I have left to do.

I have heard that chalk works too to reduce pinning as well. ("Pinning" being the name of the clogging of the file teeth.)

Question! Is this discussion about an aluminum file. Do they clog when used on aluminum?

The file is not aluminum. The file is hardened tool steel.

The hardened tool steel file is being used to file an aluminum balance tube. Gummy cast aluminum can sometimes clog the file teeth and mess up the finish.

Sorry poorly asked. Aren’t there files made specifically for aluminum?

Haha! I get it now. Sorry.

I'm no file expert, but not that I've seen.

I guess it's quite conceivable that certain file teeth shape would be less prone to pinning in certain materials, but I've not run across discussions about such features. Interesting idea.

I recently spent time helping a friend in his Vintage repair shop. He had two sets one for aluminum and one for steel and very particular how they were used.

You're absolutely right. I just took a quick look at McMaster and they have files listed "for use on aluminum and other soft metals".

I never got that specialized. I just reached in the drawer and grabbed the on that was the best shape and hoped it was sharp!!

Wonder what 240dkw used?

I want one of these but no way have the patience to DIY.

I'm assuming he used a general purpose file. Just like all the files in my drawer.

BTW - Thanks for making me look into that. I learned something today. I'm still too cheap to buy material specific files, but it's nice to know they're out there!!

You are correct, I have been using a selection of general purpose files. As well I learned something today.
