tired of hearing me swear, whine and wail about small stones falling off the dopsticks, hubby made me these: two sizes, 3/16" and 5/32", they work GREAT!!!! KD

So how did he flare out the ends like that and are they concave? I've been using golf tees and if I need one with a little less diameter, I just sand it down. That's great to have someone to keep you from yelling-I mean taking care of your needs.

"a fairly large center punch hammered into the tube", Ed....he said. deburred on a band sander.
did the toothpick work, Sands? do you use wax or epoxy?

I gotta have some of those, I hope your hubby won't mind me copy catting!
BTW KD,
When you put them in the freezer to remove the stone, does the wax come off the dop, or does the rock come off the wax? I hate the plier job crunching the dop wax off my dop sticks! I always pinch my fingers!

Fatrichie, the stone usually comes off the wax, to get the wax off the stick (work on something like a sheet of paper where you can pick it up easily and put the wax back in your container) take your dop stick with the wax on it - wax side down - and push down on the stick on the table in a kinda circular motion, most of the wax will crack off the dop and you may have nearly nothing left on the stick

Hi , Another way to bell out pipe is to run a screwdriver round the lip pressing down to get the required bell.
Some times if you hammer a center punch into a pipe end it will rupture it.

Fatrichie, the ideal result is the the stone comes off the wax. this happens occasionally! what also happens to me (too often) is that the entire "ball of wax" (couldn't resist that) adheres to the stone and comes off the stick entirely or mainly. i've damaged finished stones trying to pry the wax off the back and have started to reheat stone and wax in hot water in a small pan (thus ruining the pan for any future culinary function) on the stove to remedy this situation.
conversely, most of the time, the wax is still stuck to the dop and while you can break most of it off with fingers, there is always some that tenaciously adheres to the "mouth" of the stick. i try and heat the stick on the electric dop pot that i use and most of the time it will come loose....but it's a fiddle.

KD Are those hollow? I can get all the aluminum solid stock I need (at least I think I can still get it) but It appears that those ones are hollow- Hmmmm

With wood sticks, I put them in the freezer for five minutes and the rock pops right off the wax. But I was curious how it worked with the metal dops. I tried super glue and a nail as a dop and that was a complete failure, the rock that didn't break is still on it's nail... in the garbage! BTW, I bought some of the tubes at a hardware store today, the first one split when I tried to flare it I'll try again tomarrow when the beer wears off!

neat! Any vibration when you're grinding?

Those are cool, I don't have my grinder up and running yet, but that helps me know what I need, when I am able to grind. Your husband is like my father if we need something or he needs a special tool he will either use an old tool to make it out of or he will totally make it from scratch. Tami

I'll check KD- My dad gets it from work- they do a lot with riviting and use a lot of solid alum. stock- What diameter do you need? RIch- you gotta work that tubing S....L....O....W...... It will split real easily- I can't remeber if heating it will cause it to split easier or not-

I will try to behave! Heating worrys me a bit with aluminum, the heat transfer is terrible. I thing a slow rotating movement will give the desired result. Or maybe a flaring tool. I was trying a bit too hard!

With crazy glue as dopping medium, heat it up. Same with epoxy. It doesn't take much heat to loosen the glue and as soon as it is loose, the stone pops off, and, the glue will peel off the finished stone. As usual, moderation in the heat is a good thing. Heat slowly Aluminum doesn't anneal like steel. It flares, but, only to a certain angle. The AN flare tool is almost all the way. The standard tubing flare can crack the flare on aluminum, but, with dops, so what? With heating, also, heat the dop, not the stone. Try it, you will see what I mean.
