Gluing Rings

[Facundus Cues]

I made a few of these out of all thread and machined some hdpe blocks. I had even considered making a bunch of them to try and sell

You're kidding with that price, right?
I bought the pipe clamp components off HF for like $4-5 a set and supplied my own pipe. Total cost, under $10 for a 30"+ pipe clamp.

I use a similar device to what SK is showing, mine only cost $15 each at Lowe's and they are 32 inches long. I use mine for everything from tips to all projects that require adhesive and pressure they work great all the way around. But I agree that the ones above are pretty expensive.

The clamps shown are parallel clamps, not just generic clamps, and are widely used in woodworking when clamping big - flat - stuff, i.e. cutting boards, doors, etc. and they are worth their weight in gold in that capacity.

The problem with typical bar/pipe clamps is they flex easily so if you're clamping an 11" x 17" cutting board and use pipe clamps you will need to put them on both sides to prevent the board from bending. With parallel clamps you don't have to do that.

I would personally not use a pipe clamp to a 30" long piece of wood as the flex on the clamp would be bad enough I would actually worry the angle of clamping surfaces would distort enough to pop the piece of wood out.

Those are awesome, but I can't lie, I'm OCD enough I would consider putting 4 rods (1 every 90 degrees) so it compresses it evenly around all sides. Keep in mind - I'm the guy who lets perfection get in the way of progress - but that's ok with me as I only do projects for fun.

A couple of screws and a box of various delrin rings, tubes and such keeps things handy and out from under foot if you need to clamp something.

If you like to pre build your ring packs these little delrin jigs work pretty well. Just clamp them in a vice.

Yes I agree Chili that 4 rods would be better. These seem to do well though. Here is an idea that I was working on for shaft rings. I 3d printed these and the male threaded part has a reinforced taper at the bottom to lock it onto the shaft while the female (nut) presses the ring down

With a metal lathe and threader, you can even thread the collars on joint protectors. No clamping needed and the bottom looks clean and you won't have gaps.

You can live thread on a hightower lathe with a couple of simple jigs a person can whip up in short order.

That must be fun .
Takes me a few seconds to switch thread pitches .

Me too but for those without a metal lathe it's not that hard to live thread on a hightower and you can switch thread pitch in a few seconds once you have built your jigs. One for each pitch you would like to use. 3 or 4 should cover it.

On a more anal note. Threading those high stress JP collars? Really? Had some explode in use before you started doing that?

Have not made many of them. Why clamp if you can just thread it quick and let it dry overnight ? Makes for cleaner lines too imo.

That's why your JP's cost more than my cues.

on your

what kind of lathe are you threading on?
