I was making some inletting pins for glass bedding three different systems. One end is threaded to match the target system and the other end 1/4' UNC for a wing nut , both sets are 1/4". The 1/4"x 32tpi, a special fine, went great. Both dies are KBC house brand made in Poland. However, KBC...

My 7" Wissota brand grinder only has general purpose wheels, a 46 and a 80. They are slow and hot for grinding bits. I gather to achieve both the surface finish and tight tolerance these parts are going to require, I should use HSS bits on my Taiwanese DF1224g . CBN wheels unlike soft A/O wheels...

This is way outside my expertise, but my question should be fairly simple . I have a Mach Tach on my lathe which is giving erratic readings . Now that it's running ! The manual says VFD interference on the power, so they suggest common mode filter EH28-1.0-02-75M-X T0836R and two capacitors...

Good Morning, I hope this finds you well after last night's victory. A question at the pointy end for experts.. Yesterday I was looking for a grind that gave a good surface finish .(aren't we all) So I honed a bit carefully.I was happy enough with the sharp. It wasn't one I had ground, rather...

Finally after 10 years my metal lathe works ,sorta. The VFD and I have come to terms. It still doesn't do Jog or E-Stop. But it does do Forward,Off, Reverse and the speed adjustment pot works. To me, this is huge victory. I had used it on the power up setting for a while. It was awkward going...

I noticed on a forums couple of times guys had overcome one of the mill/drills weaknesses , the lack of power down feed. They had powered the downfeed with an adapter to their cordless drill. Their adapters went on the handle like oil filter sockets, with a couple of prongs over the edges. A...

I'm rewiring my VFD controls . This time I'm using 18ga 4wire shielded. Getting the sheath off is a struggle, is there a trick ?

I used it again today, a couple of times. It's Lufkin, that should date it. I bought off long retired Boeing machinist in Seattle . A Craig's List find that I got him to ship to the border. When I talked to him , he told me it wasn't much use, as he had rarely used it. I'm finding it pretty handy.

My mill is a RongFu-45, a square column mill/drill. It had been CNCed and was well worn when I started working on it. On your machines what kind of accuracy do you expect ?

I'm just playing around as much as dialing in. I'm very familiar with Starrett #196 button back and the common 1" dial indicators. But dial test indicators were never part of our work . So I have question . When I bought a guy's milling machine tools a couple of things were a cheap 1/2 thou and...
