remove powdercoat from threads, How?

[Hollister_Hitman]

I bought some +3+1 arms for my Gf for x-mas. I just bought the bare metal ones and had them powdercoated but some of the powdercoating got inside where the heim joints go. The heims won't screw in now. I removed the heims when i got the a-arms so I know they work. The pc is about 1-4"-1/2" inside on the threads. Any suggestions?

Try to chip out enought to see a thread or two or the actual metal at the beggining of the thread and jam a tap in there to clean it up. You could also use a pilot bit throught he hole to give you a pathway for the tap.

Ahhh. reminds me of the day a coater gave me back my spindles 100% coated...Threads, races, everything...

 

A tap is the only way to go here.. If you wanted to, file the very inside of the edges with a small file. That way when the tap goes in, there will/should be no "chip" on the exposed areas.

you dont have to buy a thread cutting tap either. if you use a thread chasing tap, or even a tapered tap, those would all be better than a plug tap, and i wouldnt even try it with a bottoming tap. there are a few different kins o' taps.
