Thread: 1/2 x 28 UNEF tap to borrow

Anyone got a 1/2 x 28 UNEF tap i could borrow please ?

Lots the thread protector for one of my rifles, and would like to make another out of acetal / deldrin.

Happy to pay postage etc.

Should have one, will check in my toolbox in the morning

I got one if he dont

Or $11 on ebay for a cheapo chinese one, I don't borrow many tools for small jobs when you can buy them so cheap, good enough for the small jobs

$7:99us on aliexpress and free international shipping.

By the time something from aliexpress or dealextreme arrives I would have finished the job and sent it back (by severel weeks)

If I was going buy one it would be a decent quality tool from mscdirect or enco etc. Don't really see the point in buying something like that for a job that I am likely to do once in my life.

internal screw cut on that sweet lathe of yours mate

That tiny a hole and such a fine pitch, no thanks

Using a boring bar and HSS cutter, don't have carbide tooling for threading yet, so there is a limit to how small a diameter I'd look at doing.

Do you want it or are you going to have a 3 page discussion about it?

All done



Thanks @marky123, tap is on its way back to you, much appreciated

Ended up having to single point it after all, turns out the gunsmith that did the barrel threading left it oversized for a tighter fit on the supressor...

What lathe have you got?
Mines a Boxford 11-30,11" swing,30" BC and a 34mm bore.
Swing a barrel blank no worries.

Myford ML7

Spindle bore is too small for barrels, probably a good thing

I'd blame the silencer maker for the loose internal thread!��
