    Video showing how a mold for a lathe bed is made.

    That planer is awesome! I have only operated big ones.

    Budget HSS lathe tool grinder

    Stanstocker I agree with you about the home shop thing. Not everyone has a team of engineers and metallurgist available at home. We work with what we have and we learn by trial and error. If some dude a 1,000 years ago can sand cast weapons and tools in his bare feet by a river then I can...

    Funny you brought the glue thing. Any foam castings in aluminum where I use glue had flaws. Tried several types none worked well. The foam disappears instantly while the glue gasses off ruining the piece. I just went to bigger foam. This was one of the first questions I was going to ask this...

    I have had good success casting with lost foam. I built several machines to cut the foam. I have some videos but they are too large to upload here. I coat the foam with a product slurry called Beadex Silver Set 90. The cannon barrel was cut using an old Buggo track burner for oxy/acet. cutting...

    Threading and the compound angle.

    Got my journeyman's card in 1980 after serving an apprenticeship of 4 years, and 2 years machine shop school as an aircraft machinist. I retired last year after 40 years repairing industrial valves. Have cut thousands of threads over the years. I am not rethinking ****, chuck up a part and cut a...

    Threading and the compound angle.

    Drill size is the thread major diameter minus the pitch. The attached chart shows drill size for a 5/8-11 at 75% will be 17/32 (.531) 11 threads per inch has a pitch .091 (1 divided by 11) .625 minus a pitch of .091 is .534 Chart says drill size is .531(very close). So if your are at "home"...

    Threading and the compound angle.

    Another advantage of having your compound at 29 deg. is you feed the compound until you reach 75% of the pitch of whatever thread you are cutting. (60 deg threads only) Your cross slide will always be returned to zero. A lot of older lathes you can set the cross slide to mechanically stop at...

    Hello Dave I was lucky to find a SB Model A at auction for 500$. It had every option including follower rest, steady rest, collet set, 3 and 4 jaw chuck and the original milling attachment. Was very lucky find.

    I live in Castle Rock, born in Yakima. One of my customers was in Moses Lake. Was Union Carbide but they changed their name after the e Bhopal disaster.

    Threading and the compound angle.

    I have always fed the compound @ 29 degrees. That way you are only cutting on the leading edge. Also your cross slide goes back to zero every time if you feed with the compound. But I have also seen machinist just plunge cut with no top rake and still make excellent threads.

    I am new here. I am interested in lost foam casting and have built several contraptions for cutting the foam. Attached is the spokes to a flywheel being cut on a router table with a hot wire. E. Davis

    Not in Kansas, in Washington state. Retired machinist/welder. Send me what files you got and I will look at them. I use Autocad 2024 for all my drawings. E. Davis
