Re: New Controller?

Just to update the thread, I found a Dell OptiPlex with WinXP. The driver test runs "excellent" up to 100kHz. This PC only runs the CNC with Mach3 and a few test runs worked just fine. Now I'm going to install the old PCI parallel port card and try to configure the pendant again. I forgot what happe...

Re: New Controller?

I was explaining the situation to a friend and he asked, "can't you just turn the knobs?" :lol:

Re: New Controller?

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 M...

New Controller?

I was still running Mach3 on my Boss3 Bridgeport with the original stepper motors. Has always worked well enough for me, and I use the blue screens with probing feature. That is until last week when the PC locked up and would never boot again, no POST and all supply voltages measure in spec. I recal...

Re: Taking Chinese 3 Jaw Metal Lathe chuck apart for cleaning

I solved my problem by attaching a shop vac to the back side of the spindle. Easy on my Graziano---just duct tape a triangular attachment to the gear cover. The results were exceptional. No dust in the shop, with virtually all the chips ending up in the shop vac. I recommend against the idea of int...

Yeah, the worst is boring cast iron or cast steel where the back of the bore drops right in on the scroll. What a mess... I've tried pugging, but that usually just causes pile-up and recut problems for me.
Blow air into the back side of the spindle?

Re: Material for Small Vise

Thanks for sharing, and that is a more efficient use of material than what I was considering.

Re: Material for Small Vise

I've never played with 4140, so maybe just for the experience...

I've had great finishes with 1018. OK, I sanded the table but the rear faces are off the end here. I was just thinking it would get all beat up in no time.

Thanks :)

Material for Small Vise

I was considering making a small machinist/grinding vise set. ~2x2x4" long. I considered some 1018 scrap I've had laying around, but figured something like 4140 would be better. Turns out, since I've not been playing much machinist lately, I don't remember steel prices being as high as they are and ...

Re: Bare Metal Protection

I bought one of those Sure Shot sprayers and mixed up some ATF, kero, and bees wax. I tried that this past winter and all seems fine. Of course most everything already has a patina. The few new bits still shine though.

Published Caliper Accuracy Specs (Mit)

I see Mitutoyo 8:" digital caliper accuracy spec is 0.001" and 0.01 mm. Metric measurements are published as being more than twice as accurate and equal to resolution. Why is that? Mitutoyo 500-475 Digital Calipers, Solar Powered, Inch/Metric, for Inside, Outside, Depth and Step Measurements, Stainl...

Re: High Flow Shower Hose

WoW! I didn't know they made a shower sized Waterpik! You guys take clean seriously... My shower head is like 5" diameter and has about 50 rubber nipples that shoot water. That is fine but the valve is a single handle that you twist more for hotter, so it just goes on full blast. Sometimes I like to...
