Re: Size of Grinder Pedestal Platform?

Steve, I find some space in front of the wheels useful for clamping on temporary accessories, such as jigs for grinding long woodworking chisels and such.

Re: Upgrading Harbor Freight 20-ton Press to Air

Liveaboard,
I added a HF 20 ton air over hyd jack to my press, and it has the standard jack handle style pump as well as the air system. I use that, as you suggested, for fine control.

Re: Huanyang VFD 2.2

I believe you are correct about attitudes for combo machines in the US. Our experience over the years was that machines claiming multiple capabilities rarely performed any of of them well and were cheaply constructed. An exception may be the Shopsmith woodworking machines. I've never used one, but t...

Thanks for the clarification guys, I hadn't realized what type of machine an X 31 was.

Re: Huanyang VFD 2.2

Liveaboard, I'm far from expert on VFD's, but I thought I have read here and other places that the typical VFD doesn't work well with multiple loads. If that is true, and I hope someone else can confirm or rebutt, a VFD might not be the best choice for your friend's 3 motor machine. Perhaps a phase ...

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...
