Yes.

I haven't tried anodizing yet but from what I've read you can't simply trade off time for current because the finish depends on the current density. That one looks suitable to me. I recently scored a couple of big honk'in programmable supplies (one 0-20 V 0-20 A, the other 0-60 V 0-60 A) so I may gi...

Are the cast iron parts that come from Allen, Little Engines, Mercer, Etc made from grey iron or ductile iron? I have read in several places when recommendations are made to make things from ductile iron but ideal -vs- economical or expedient or even availability are different things so I would lik...

I have a set of "coated" drill bits purchased at a yard sale that are like that. My guess is that they are high carbon steel that never got heat-treated due to a manufacturing screwup.

Fortunately the index they were in was worth the $2.

If you simply cast ceramic around your electrode differential thermal expansion will almost certainly cause a failure unless you match the coefficients of expansion. There is also a risk of a smooth electrode being blown out when the cylinder fires (the insulator can also blow out of the shell: I ac...

It was the Centroid Acorn system that I was looking for. Reading more, I see it requires Windows 10. Somehow I thought it was a fully contained controller and would just need a monitor and HID. I also see it wont support my pendant - which I never got set up anyway. I guess I'll have to read about ...

The link belts do have a direction, and they don't give a "this is what will happen if you run it in reverse" comment, so I don't know what the effect would be. I have run my atlas in reverse with a link belt, but since I have a threaded chuck, it was only very slow to remove a tap or die from a pa...

I read 280 but it looks to me like it's been restamped and then scraped. I think I see the remnants of a "1" to the left of the "2".

Star connected 480 is 277 phase to neutral. That makes no sense to me on a motor nameplate, though.

Mr Ron writes: Before the use of polarized plugs became standard on all electrical devices, the return leg of the device could be wired to the return leg of the power source. Reversing the plug in a receptacle, would make the entire device hot. I don't believe that it ever has been permissable to se...

In standard notation the axis that the cross-sllide runs parallel to is X. Z is the axis of rotation of the spindle. Y is what you are calling Z. When turning a small movement of the tool up or down results in very little change in depth of cut so a tiny tilt to a part being turned between centers c...

Under the current code GFCI is not required in a shop for 220 outlets, hardwired machines, or dedicated outlets. I know a number of people who have had bad experiences with the outlets with built in GFCI. One of them had the outlet catch fire. I have no GFCI and have no plans to install any but if I...

If you are cutting threads with a pitch of 1.75 mm and your leadscrew has a pitch of 3 mm each turn of the leadscrew will cut 1.7143 threads. Thus your threading dial has to account for that ratio by moving one full interval for every .58333 turns of the leadscrew.
