Re: Caliper for Marking

I do as you do with my old vernier caliper. Some previous owner did that so much with my Helios dial caliper that it won't scribe a line any more.

Re: Talk tractors

> No doubt many of us were. I dabbled into restoring until they worked, then used them. Same here (except that mine ran as purchased). My first was a JD60. I now have a Ford 8N, an IH544 utility, and a Farmall 560. Current focus of efforts in my shop is the JD lawnmower, but I need to do quite a bit...

Re: MT3 tang issue

Perhaps some of these tailstocks that standard Morse tapers with tang seem too long for are designed to take a stub taper.
