    Inspect the boom on that think carefully before using it.

    I almost bought one for insurance salvage after it rolled off trailer and over. The booms on them are over-reinforced on bottom for the...

    I know a shop that scrapped a $5000 piece because they were too cheap to make a boring bar.

    Good job!

    If the problem is the circumferential crack I see in the elbow, I'd fix it in ten minutes with 5-minute epoxy and torn bedsheets. Rip 2" wide strips of sheet, soak in liquid epoxy, and bandage the...

    I, too have done quite a bit of cast iron welding over the years.

    Exhaust manifolds and grate bars IME are the worst to weld. Manifolds tend to be thin and large, and both often act barely...

    Thanks for all the thoughts.

    The stone my son got is a long ellipse, with a nearly square cross-section. Looks like Al2O3. The oval-section scythe stones I have used, like the ones Joe...

    Wet or Dry Sharpening

    My son bought himself an Austrian-style scythe. Brought it here for help setting it up. I have a fair bit of experience with American-style scythes, and find them more rugged than the Austrian, but...

    You might make a couple of special fixtures that you can use with many different parts.

    One would be like a vise with very shallow jaws. The fixed jaw has a sharp edge the cuts into the work, top...

    I have soldered and brazed quite a few fuel tanks. The old ones were terne plate...a lead-tin coating, easy to solder where not rusty. Aluminized steel would be hard or impossible to solder or...

    Thanks for all the kind and helpful suggestions.

    I may have misled with my assumption that it is a universal motor....Armature and windings appear to be in series.

  17. Brush-type universal motor question

    I have a Master Appliance heat gun. Old, heavy duty, American-made. I love to fix and use such things.

    Won't run.

    Field windings show around 30 ohms each. Sounds like a probably okay range....

    I'm probably not the only one here who lies awake regretting the things I did not buy.
