    Lucas 41 HBM head alignment issue

    I'm not sure if I understand correctly your description, but to me it looks like the problem is in the ways and gibs of the table and saddle, allowing it to twist when moving it back and forth. Try pushing the table toward the spindle on the operator side and away from the spindle on the...

    source for cannode blue and yellow (or red)

    My understanding is that Canode inks are discontinued. I am getting good results using Charbonnel Aqua Wash etching inks (available from many suppliers, I have take one randomly for the link). They are a little thick and need to be diluted with a couple of drops of water/Windex, but the Prussian...

    how do you measure the fit of a collet?

    On the top of Bakafish suggestions, I would cover the outside of the collet with sooth, insert a pin very close to the collet nominal size, and tighten the collet in the holder: observe where the sooth transfer to the holder. If you have an equivalent number of "spots" in the front and the back...

    evaluate flatness of a surface plate with a level, straightedge and a pencil.

    I think that putting shims under each end of the level would work just fine (hopefully you expect imperfections much smaller than the thickness of even the thinnest shim at hand). One consideration about moving only half the length of the base of the level at each time: doing so, you end up...

    Better handle for Sandvik hand scraper

    Here is my solution for Sandvik and other scrapers (e.g. Anderson): I made a few of them for the scraping class that we hosted at Tuckahoe a few years ago. The prototype was bored out from a bar. The production series was made by two pieces loctited together: the cap from the same bar and...

    Weight of Cinci #3 combination mill

    John, If you really want it, you might consider renting a larger forklift for offloading it. If it comes with 20-25 arbors as the only tooling, I don't know if it is really such a great deal. all you would ever need is a couple of straight ones. If, instead, it comes with 20-25 tool holders...

    Got some bits and pieces , need ID help

    Clearly a South Bend cross-slide and compound (not sure if for 9", 10K, or 10L). The stamping under the compound casting should help you identifying what model it is for. You can check if the follow rest bolts to the cross-slide (i.e. comes from same model lathe). No clue on that sort of...

    DIY Metal shaper questions

    I believe that you need a minimal cutting speed in order to achieve a certain finish and not to prematurely destroy the tool. On Youtube you can find several close-up high-speed video of lathe tooling cutting at various speeds: there is a lot going on and, at optimal speed, the very cutting edge...

    Strongest rod available

    Maybe I am guessing wrong and, of course, I don't have any clue about how much free space you have around the pin inside the receiver. However, if spatially possible, my solution would be to have a tight clearance hole in your pin and have the pin passing through a bushing which has a threaded...

    #4 morse taper sticks in spindle?

    The taper of many MT drill bit is interrupted by a rebated band roughly in the middle. This reduces significantly the contact surface between the male and female taper. Perhaps, you might do the same with the taper of your chuck. Paolo

    Newbie scraper in Japan

    Definitely, in order to make curved scraping marks like, I believe, is rather popular in UK, you need to do "brute force" pushing just with your arms. And, I guess, for that type of scraping, you would rather use a fairly rigid scraper. I am just an hobbyist. true, I don't have to put bread on...

    Newbie scraper in Japan

    A few general considerations about scrapers, blades, etc. I started experimenting scraping with tools that are far from ideal: very stiff and short carbon steel scrapers sold by Enco (before getting swallowed by Grainger), Anderson scrapers and, finally both 20mm and 30mm Sandvik ones. At the...

    Newbie scraper in Japan

    Homemade scraper - cheaper and better than most of commercial ones Finally, today I managed to go to Tuckahoe and take a few pictures of my scrapers. Here is the one I made (my favorite) At one end there is a piece of 1/4-20 brazed-in to attach the flapper disk Whereas at the business...

    Newbie scraper in Japan

    Welcome on board, Bakafish! Regarding the radius of the blades, especially at the beginning, it is easier to use sharper radii, since they are more forgiving if you do some mistake in controlling the lateral tilt of the blade. Sharpening: for cast iron you generally use approximately between...
