Re: Shop Uses for Scuba Tank?

A lot of high end air rifles are called PCP for pre-charged pneumatics and operate at quite high pressures, around 3000 psi. Sometimes they use scuba tanks as a portable refill source. You can even get hand pumps that go north of 3500 psi. They look like old fashioned bicycle pumps, but I'm guessing...

Re: Storing End Mills

So I ordered the ice trays I mentioned yesterday, and thru the magic of Amazon (love em or hate em) I got them today. They have a silicon insert, the blue part, that is flexible to enable pushing out the ice sticks, and it has a greasy feel to it. Although it feels greasy, I can't detect any residue...

Re: Shop Uses for Scuba Tank?

Steve, don't know about where you live, but in a lot of places you can't even get the tanks re-filled without a cert card.

Re: Storing End Mills

For folks that live where amazon operates, I found these that are pretty darn cheap. https://www.amazon.com/gp/product/B07HQYG9TY/ref=ox_sc_act_title_1?smid=AZA0I12YMQNES&psc=1 Ironically they don't get very good reviews because of some residue on the silicon that can affect the taste of the ice, bu...

Re: Determing the size of a lapping tool

Sorry for a late reply, been away from the cmptr for a while. Thanks Pete, and RSG, sensable advise from both of you Pete the rifle is a Savage model 10 and the scope is something I haven't tried before, from Primary Arms, a PA3-18X50 Silver Series. I bought it because it has a 6.5 Creedmoor specifi...

Re: Determing the size of a lapping tool

Steve, the rings should be fairly close as built, so not much needs to be removed. I suspect a 30 mm reamer would cost way more than i'm interested in. LoL This is a common thing for shooters, and several folks, such as Weavers and Sinclairs sell tools for the job and all of them are lapping tools. ...

Determing the size of a lapping tool

Hey All, I want to make a tool to lap a 30 mm bore and I'm wondering what diameter it need to be. Some of you probably guessed from the 30 mm, it's for rifle scope rings. The rings are steel, and the purpose of the lapping is not so much to bring them to size, but to insure the two rings are aligned...

Re: How to Make a Patient Lift Roll up to Low Machines?

Not something I have personal experience with, and not useful for a shop, unless it's a large one, you might consider what harbor freight calls a "truck crane". Others sell them as well, but seem to be good for about a half ton or so. For your original issue with moving rocks, it would seem to be us...

Re: craftsman 15-1/2" drill press - buy or not?

Yep, that works well, if you keep the column clean, and a little dry lube helps a lot.

I've added a motorized table lift mechanism to mine with hardware from an old hospital bed. I also switched to a DC motor with speed control and a tach readout.

Re: craftsman 15-1/2" drill press - buy or not?

P.S. I forgot to mention, just as a reminder, that this drill press is like most consumer presses in that era, and does not have a cranking system to raise and lower the table, just a clamp to loosen, then gravity and muscles take over. Usable, but not nearly as handy as newer machines, and the pote...

Re: craftsman 15-1/2" drill press - buy or not?

I have a similar Craftsman drill press, mine has a more industrially oriented table, with tee slots and coolant channels, but it shares the 8 speed pulley system with a 1/4" wide vee belt. I bought mine new in 1970, and can truthfully say it has never given me the first lick of trouble. The most ama...
