Re: Dum switch to motor (HELP)

Need a better picture, the flash is obscuring the nameplate "reverse leads xxx & T8 for CCW".

Re: BXA toolholder

You can take a guess from the toolpost exterior dimensions, but you really need to measure the dovetail with pins. Unfortunately... while AXA/BXA/etc. are sort-of-standardized by lathe size (tool height), it seems like every manufacturer uses a bit different dovetail dimensions for the same size cla...

Re: LED Shop Lighting

Well... as luck would have it, Sunday evening I flipped on my HD high efficiency 4' workshop fluorescents and after a few minutes one of them blinked, sizzled, and was dead. The electronic ballast was kaput. I reread the thread and ran over to the HD before they closed and looked at LED retrofits. U...

Re: Where to find large morse taper drills?

Yeah, I've looked at those, but most with a MT3 shank only go up to 1-3/8" insert diameter and cost twice that of an equivalent HSS drill in the same size. There are some combo sets (pilot drill, a shank, and multiple insert sizes) that go up to 4", but they start at about $700 per set. I had though...

Where to find large morse taper drills?

Why do drill bits with taper shanks only come in a limited diameter range per taper size? My lathe has a MT3 tailstock and it is very hard drill bits more than slightly over 1" in size (mostly a maximum of 1-1/16", occasionally 1-1/4"). The absolute largest I could find in MT3 was a 1-1/2", and that...

Re: Where can I buy this thread checker

A few places have them.. but not real common. I haven't bought one yet, but I think I would prefer the wire cable type for storage and portability reasons.

Re: Need to remove a broken tap in cast iron

Tig weld it!

Tig weld a button on the top of the HSS tap. Heat cycle, dab a bit, and repeat until you have enough of the shank built up to grab and back the tap out.

Re: How to indelibly mark plastic oil bottles?

I have the same bottles and have found labeling a piece of masking tape that goes around the bottle works great if you use some clear tape after to cover the masking tape, going above and below and all the way around. Hmmm, yeah, maybe. I had previously done the masking tape thing with permanent ma...

Re: How to indelibly mark plastic oil bottles?

How do you get the labels to stick to the bottle long term? I tried a stick-on Dymo label (thermo-print tape, not the embossed stuff) and it loosened and fell off after a bit from the oil. I had thought about printing a label, sticking it to the bottle, and then putting some clear heatshrink over th...

How to indelibly mark plastic oil bottles?

I use a set of HF plastic (polyethylene) bottles at the lathe and the mill for easy dispensing of all the needed fluids, way oil, cutting oil, coolant, WD40, etc. as I work. The bottles themselves hold up great, easy to dispense and get down into holes, easy to see how much is remaining in the bottl...

Re: What is this Mystery Attachment/Tool

Agreed, its a ball turner. The setting pin is at the center of the pivot axis allowing one to zero the cutting tool at 0 ball radius. Then setting pin is removed and the tool is back off with the graduated handle to the desired finished ball radius.

Re: Rockwell 21-100 Spindle Lubrication

You can't really, not without removing the spindle. You can drop the spindle down and squirt in side oiling port, which will coat the top of the spindle body, but the top bearing usually has a seal. The bearings are supposedly suppose to be oil bath, but there really isn't anything to retain it. Kin...
