Anybody any ideas how I can clean out an internal thread on one of the sidecar fittings - I have just had them powdercoated but forgot to tell them to protect the threads. It is approx 20 mm dia but the biggest tap I have is an M12. I thought of a small wire brush in the drill. Anybody better that? :bow:

Get a bolt of the correct size and use a hacksaw to cut a 'v' shaped slot in it. Use this to clean up the thread.

Only thing I can come up with apart from buying a correct tap for the thread is to file two flats on a same sized bolt and try running that down the thread.

:dunno:

Put some masking tape round the outside of the hole and then use paint stripper to soften the coating. Then do as IanR said "Get a bolt of the correct size and use a hacksaw to cut a 'v' shaped slot in it. Use this to clean up the thread." That will do it I used this technique last night when I was putting my powder coated engine casings on and the dipstick hole was coated on the inside. :beer:
