    Just picked up a horizontal Mill, what kind is it?

    That looks like a Rockford horizontal mill to me. Look them up on lathes.co.uk

    Help With Shaper Repair

    I only welded the galled areas. This left a few inches of untouched way on each end of the ram. My idea was to indicate off of those areas and the other way to make sure the cut is straight.

    Help With Shaper Repair

    I am looking for someone with a planer or large shaper that could resurface the ways of my Havir 8 inch shaper ram. The length of the ways is about 20". The ram had extreme scoring (~1/16") across nearly the entire way pictured. I built it back up with RCI-b, so it is soft & homogenous...

    Carbon Steel Cutting Tools

    The tooling with the 16 inch shaper for sale (here:https://www.practicalmachinist.com/forum/threads/antique-16-metal-shaper-for-sale.415780/#post-4105175) looks like it may be forged, and the machine seems to be of the right vintage. If anyone here winds up buying it, it would be interesting to...

    Carbon Steel Cutting Tools

    Indeed. I've got a lot of books for 5$, and then paid 10$ for shipping. For the knowledge, it's still a good deal I think.

    Carbon Steel Cutting Tools

    On a similar note, does anyone know how carbon steel and hss slab milling cutters were produced? I can imagine they were turned on a lathe or planer, but I can't find any actual info on their manufacture on google.

    Carbon Steel Cutting Tools

    I've read that, for shaper and planer work, high carbon tools will give a better surface finish than hss. I intend to test that out someday. In my older books, they mention 'emery wheels', are these the same as sandstone wheels? I had assumed they were emery paper pasted to a metal wheel for...

    Carbon Steel Cutting Tools

    Animal, stellite and other 'cast alloy' cutters should be non-magnetic. Easy way to check. Another interesting bit mentioned in a very old (1875 or so) planer manual I read, listed using white cast iron as a cutting tool. I'm trying to find that manual now and grab some more info from it.

    Carbon Steel Cutting Tools

    I have a 1907 copy of "Hardening, Tempering, Forging, and Annealing of Steel" by Woodworth. It is intended for toolmakers and makes mention of self hardening (i.e. air hardening) tool steels. So apparently they had air hardening tool steels fairly early.

    Carbon Steel Cutting Tools

    So then the old carbon steel tools would be the equivalent of W, O, and perhaps A & D as well?

    Carbon Steel Cutting Tools

    In the days of yore, there was no HSS; all cutting tools were of forged and quenched carbon steel.... Or so I'm told. Does anyone here make and use their own carbon steel cutting tools? In a couple of my old planer & shaper manuals, there are data tables for carbon steel cutters. They seemed...

    Small Horizontal Mills

    A quick Google says the Abene VHF3 is ~2900, and bridgeports usually around ~2200. Not a humongous difference. For all the Bridgeport fans in this thread, you can rest easy knowing that I also plan to get one at an upcoming local auction.

    Small Horizontal Mills

    TheOldCar - I think that mill is a little too small for me, but I will keep it in mind, thank you. Knowing now that the Abene mill spindle pivots like that, perhaps I will call about the one in the craigslist ad posted earlier. The trick will probably be finding a way to ship it from there to...
