Re-tapping threads

[willsy01]

Suggestions on who to take a frame to to have the ISCG holes tapped after the powdercoater filled the threads with powdercoat despite me saying they will be used?

Please don't say Gripsport. I'm not sending it interstate to have three holes tapped.

Thank you.

Go to repco and buy the $10 hand tap kit and do it yourself. Its just powdercoat so it will re tap easy as

 

[willsy01]

$10 you say......interesting.

can you use a pin/sewing needle or prescription glasses/ jewelry screw drivers and carve the paint out?

What cooki said, not what Chops said. Take the M4 or M5 (whatever it is) bolt with you to make it easier.

Bunnings to the rescue.

check pitch of threads........

 

[willsy01]

They're M6......Bunnings has a test panel thing with all the different thread pitches as well.

lol, re-tapping a thread hardly requires the expertise of a toolmaker!

Yeah your right but ide be buggered if I'd let just anyone with a set of taps touch my frame.

Fair point!

Gymea I believe....

That's a decent drive just for 3 thread taps but if you want to come this way just let me know.

 

[willsy01]

Thanks dude......i'll keep that in mind. I'm not too ham-fisted so i'll cautiously have a go with the tap kit provided the pitch is right.

Im sure your LBS will help you out

they are M6x1.0. buy the tap and you can use it on the caliper mounts as well.

This.

Willsy, running a tap through it I reckon there's a really high probability of cross threading the tabs. I've got the taps and a proper tap holder and I'd still be doing it the way Chops suggests.

If you can get most of the powder coating out, you can make a ghetto tap out of a M6 bolt, with a couple of groves filed perpendicular to the threads, and use it to clean the rest out.

Edit: Pro tip for next time, put some bolts in the tabs before giving the frame to the powder coater.

I recently had a similar problem with a stubborn pivot bolt. I took it to this small shop in the industrial zone that sells nuts and bolts as well as making custom nuts and bolt etc,
asked them nicely and had a professional do it in 30mins for $15. I can't say everyone would do this and I am fair way out of the city and managed to find a place that would
but asking never hurts.

Professional re-tap + 30mins + $15 = win

I rounded out Allen head in rear axle pinch bolts in my old 222 back in the day. I took it into an engineering place to seek assistance. They had never seen anything like a Dh bike, and were fascinated. 10 guys including the boss stopped work, looked at the problem, had a round table, worked out the best way and got it done, just for the challenge and novelty, didn't charge a cent (I think they decided to tack weld an Allen key into it, and even gave me a new bolt)
It was Friday arvo, so I returned with a slab for them.
Ask nicely, be genuine, and people are more than willing to help out.

Hey! Who hacked my account with all these helpful comments and positive sentiments???
