Was just rummaging around on the Schmelke site, they have one as well. 1/2 13 outer, says 5/16 14 inner, I'm assuming it's the qr version. They are pretty inexpensive too.Okay, was wondering if you had a way to make an allen wrench fitting on them, like cuefits had on their POM fittings.
I have to ask, what did you cut the .550 head off with? Maybe, my speed or feed were too fast it got hot and hard to get a nice clean finish cutaT At any rate, i don't know why you would need an alignment barrel. Just cut the head off and face it off. Paul Huebler handed a friend of mine one of his inserts, nothing but a piece of nylon threaded on the inside and out no alignment barrel etc That friend just showed this to me a day ago he still has it.Let me clarify, I was speaking solely about the Huebler repairs. When I did those yrs ago, I didn't think to use a threaded nylon bolt as an insert. On regular shafts, I bore approx. .420" hole, tap at 1/2x13 and then bore the end to fit the .550" head. The dowel was a test run, and got tapped for 3/8x10.

I do the same. i was just curious how Huebler could have threaded those uninstalled. Seems like it would have been a lengthy process, nylon is more flexible and gets hot if machined too fast. The nylon does offer a quick economical insert optionJust my choice
I do the internal threading after the insert is installed. I do all my inserts like that.
He could have bought them like that, just like they sell the brass inserts.I do the same. i was just curious how Huebler could have threaded those uninstalled.

I use an insert cutter made to cut aluminum and run it about 900 rpm. Cuts smooth. Then I center drill and drill/bore and tap.I have to ask, what did you cut the .550 head off with?

I'm sure we are both using the same index cutter, i may have just been going a little to fast. i don't see any reason for that cap,, since the threads are cut in a .420 bore That cap serves no purpose. I just took a challenge and wanted to be able to make an insert from anything. i have the nylon, hydex, ,phenolic, brass inserts and brass plug blanks There shouldn't be anything i can't plug.I use an insert cutter made to cut aluminum and run it about 900 rpm.

I like those no threads just a glue relief. Are you using west system on those I do use Bob Sitith slow cure on most?As someone that would like to, but cannot currently live thread, I understand wanting to run all the way down all at once. With a quick change post I get a good rhythm going and it doesn’t take that long to make a batch advancing the rod an inch at a time.
I use phenolic but I like a 3/4 inch insert and the rest of the pin threads into the shaft wood. If I am plugging a wood threaded shaft I add a Katalox plug first and then the phenolic.

Been using Max but almost out. Thinking about T-88I like those no threads just a glue relief. Are you using west system on those I do use Bob Sitith slow cure on most?
the .550" cap is so when done, you don't see a spiral from the threads. It's a full circle. if doing a fully threaded plug, it will look lopsided and will show the epoxy line which, performance wise is not an issue, but from a professional side looks horrible.I'll post a video next.I'm sure we are both using the same index cutter, i may have just been going a little to fast. i don't see any reason for that cap,, since the threads are cut in a .420 bore That cap serves no purpose.
