ive had the dry build line up fine on the steering then sent bits off for powder coating
the problem comes when ive gone to put it all back together
the extensions are coated and now the rack carnt screw in to them far enoght

is there anyway of getting the powder out of the threads inside the extension
I know tap but buy the time the taps in its hittings the bottom
I carnt get the bottom half clean ??????????????????

is there a chemical I can por in to melt the powder ????????

Scrap bolt, cut some slots in the thread like a tap and use that to clean the threads up.

I was going to suggest a bottoming tap, but considering it's just to clean up the threads rather than cut them the cut bolt idea seems like the best approach to me.

Probably the dust is adhering to the part due to electrostatic forces.
Water and degreaser or spirits should do the trick.

Pop some nitromors/paint stripper in there very carfully, then use the old bolt.

You can be thread cleaning kits from the likes of snap on,if you've got any m8's work in a garage they might have a set,like a tap but not made for cutting new threads.

Just use the plug tap, ie the one with the fullest amount teeth on it, it will on take out what isnt supposed to be there

Fill with acetone or nail polish remover? That should soften up the powder coat...

Next time, leave some old bolts in the inserts!

It is much quicker to remove them, than re-tapping!

nope, that tears the powdercoat as you remove them.
silicon plugs could be used.

Next time use a decent powder coat firm who mask the holes!

Bolts are fine as log you remove them before the coating goes hard/cools
