    Probably would mount it on a rotating fixture to do that. My last comment was trying to ask: Should I walk a red spot down the length? It seemed obvious to me that I would never be able to get the...

    Thank you for info.

    For a 3 or 4 foot length, just run torch down the length at a pace to keep the surface red?

    Preparing copper tube for bending?

    Type K - OD = 0.875 ID = 0.745
    Type L - OD = 0.875 ID = 0.785
    Type M - OD = 0.875 ID = 0.811

    I have bent Type K annealed tube with a bending jig. The 7/8 tube was...

    Shrinkage will be more in one direction than another depending on grain orientation.

    If there was doubt about the wood used, scrap Douglas Fir that was dry.

    I rented a drop bed trailer for a day. $25. You can roll it on pipes but I used a dolly with a wheel on each end. The bar of metal looked like this: |_______|, with each upright end having a wheel....

    Thanks guys.

    Maybe a sheet of plastic with over-sized holes as the inside part. And a strip of aluminium on the two sides. Of course it has to look good. :D

    I will leave the wood for now. Might...

    If you look up the price on a new vise swivel base it's about $350. The price for the package deal is low enough for anybody.
  9. Will this copper coil support cause the tubing to fail?

    Rolled a 50 foot long 7/8" diameter tube into a 10.5" diameter coil. The wood pieces are 1" by 0.5". I calculated the incline for each hole to be 2 degrees. The coil has 18 turns and is 2 feet tall....

    Have you seen the size of the cup that is sold with your spray gun? It's huge. Your arm will drop off from fatigue before anything else.

    There is no argument. My points are:

    - Dr. Devilbiss and Joseph Binks came up with spray gun technology in the 1800's. What did furniture makers use before that? LOL

    Most people would run a service line from their main box to a disconnect switch in the garage.

    If you look into getting a magnetic base to hold indicators recognize that some hardware that works with Brown & Sharpe will not work with Starrett and the other way around.

    I built my dining room table in 1990. It has a hand rubbed finish. I'm not sure what you mean by "upkeep" besides periodic dusting. I have done a few touch-ups for scratches without moving the table...

    Most have their own definition of "fine". They would not know the difference between a hand rubbed finish and a spray can coat of Deft.

    Just clean them see how they work. If deemed unsatisfactory then a points job may be ok to quiet down a 12V relay. A higher voltage relay will eventually get no better, maybe even worse. In the...

    Make a RPC. Figure out or ask how to make a good one, not one of those skimpy designs floating around on the internet.

    I like stainless too, until it galls out on me.

    A side issue is how did those screws deform. If the end is mushrooming then the hex head must not look so great.

    Have never seen one of those up close except in a picture. What you propose would make you massage the inside electrics so that everything works. For me, no thanks.
