Re: all-thread studs for clamping

I can't imagine tightening anything to the mill table so tightly as to threaten even the worst threaded rod. I have seen table slots broken from over tightening. Including table slots that take a 7/8" stud. The big reason for me on the of B7 is they last so much longer than the ones you get in the ...

Re: Good practice question

I like these tracer point/extended point live centers. https://www.travers.com/revolving-tailstock-center/p/63-301-787/ Of course the old standard live center is really nice to, but often times to large to get the tool close on smaller diameters. https://www.travers.com/revolving-tailstock-center/p/...

Wait, I thought you were supposed to hold the tip in your left hand and the round part in your right?? Or is that just in the western hemisphere? :)
I have always done it like the video, only I use a 6" wide belt sander on large drills. I prefer an 8" grinder though for most drills.

Re: Layout dye

I did have a can of white at one time. I find that different colors work well for different materials and lighting.

Re: Lathe setup question(s)

First off, my old Enco lathe isn't much but at this moment it gets what I need done. Specifically, that is how to understand the operation of a lathe, tooling and materials. Not proud but it works. It is a good machine to learn on I believe. My first question is, when I put a piece of 1/2" drill ro...

Re: lapping internal taper?

I would cut the bore with a cermet insert at a high RPM. It will give a nice finish. I made an adapter for a cylindrical grinder that had an ID attachment built on the back. They wanted me to make it for a 1/4" shank. I had suggested making something with that had the male taper for the grinding spi...

I was hoping you could cut V slots.
Looks like it would.

Re: What are these?

Actually these can be used in the mill to cut an angle on the side of a part as well.

Re: What are these?

Taper reamers. No I can't use them in the past. I used them on injection molds although maybe not the same taper.

Re: Wheel Press

this press was designed for 200 ton capacity and used water as the power fluid, explaining the copper liner and brass pump and pipe fittings. I have actually used one of these in a shop. They call it a water press, but really they mixed soluble oil in the water. When it ran low due to evaporation y...

Re: Tightening a chuck

The idea is that the chuck wrench provided is the max tightening need for a particular size chuck. While on small diameter chucks being tight is not as critical. However on larger 12 and 14" and bigger chucks if you are not tight enough, the scroll will loosen when turning on the spindle. Reason bei...

Re: Spindle collet grub screw

The pin/screw to is not meant to be a driver of the collet. But is there in case the threads are tight to keep the collet from spinning while removing the collet. This rarely happens and then you would need a collet wrench if the screw/pin is missing. I have only had this happen once that I can reca...
