    Powder painting a flywheel

    And yes boys and girls---Even the old and the lame can build a fixture to hold flywheels for powder painting. Nothing has been cleaned up or ground smooth yet, even the flywheel is dirty---but---It gave me something to do this afternoon.

    Powder painting a flywheel

    dsage---read my whole post. I cover the issue of masking one end of the exposed shaft in my previous post. I would hang the flywheel from a piece of wire as you suggest, but then the wire itself would mask the powder paint, leaving a line on the side of the flywheel. These flywheels are quite...

    Sandblaster!!!

    I am very happy with my sandblaster. One thing that I may change sometime in the future is the angled cone in the bottom. On this sandblaster, the cone is very shallow, meaning that the sand settles on the sides of the cone but doesn't slide down to the bottom of the cone very well. I may make...

    Powder painting a flywheel

    Items painted with powder paint should be painted "everywhere" in one go. There may be a way to powder paint and bake one side, then after the part has cooled off, flip it over and powder coat and bake the other side, but I'm not sure you can do that successfully. The model below shows what I...

    Powder painting a flywheel

    Right at the moment I have no plans for powder coating cast material. However, powder painting is so new to me that anything is possible. I'm still having problems with my good leg, but I think it is getting better. If I'm lucky, I may be well enough to make the stands that these two flywheels...

    Powder painting a flywheel

    dsage---Thank you. I did know most of that. I've read a lot of write ups about the application of powder paint, what it sticks to, what it doesn't stick to, and what screws up the finish. I didn't do anything today. Today my left knee, the one not operated on was giving me all kinds of...

    Powder painting a flywheel

    Okay---we'll try something different. These flywheels are one piece, and I'm sure of that because there is no paint on them to hide things. They will not have to be sandblasted, but will be wiped down with thinners and cleaned up with a lint free rag, then straight into the powder paint booth. I...

    Powder painting a flywheel

    This is the flywheel after sandblasting. 99.9% of the paint is blasted away. I didn't realize it, but this flywheel is made up from three different pieces which have been pressed or Loctited together. Powder paint has issues with this as any oil trapped between the pieces tends to "boil up"...

    Powder painting a flywheel

    A few years ago I designed and built this i.c. engine, and at the time I painted the gas tank and the flywheel with red spray on enamel. As time went by, the enamel paint on the flywheel got chipped, scratched, and generally buggered up. To redo this flywheel with powder paint, the enamel paint...

    Powder paint for model engines

    Well Sir---There is fast, and there is "damn fast". Considering that I only ordered this thing four or five days ago from California, this oven was delivered "Damn fast". I just received it and unwrapped it ten minutes ago and I still have to read the literature that came with it. I am...

    Sandblaster!!!

    I've had a lazy day today---mostly. One thing I will mention---the light for use inside a sandblaster cabinet as sold by Princess Auto in Canada isn't bright enough to do the job it's intended for. I just added a simple light fixture with one 60 watt bulb in it shining down thru the glass to...

    Powder paint for model engines

    Today I sucked it up and ordered a powder paint curing oven from Eastwood. I have tried one used toaster oven and it doesn't consistently go up to 400 degrees. There are many used full size electric kitchen stoves with large ovens for sale in the buy and sell newspapers, but they are all...

    Sandblaster!!!

    This is the other side of the antique wrench sandblasted at 50 psi air pressure. It seems to have taken the same approximate time as the first side and cleaned up very well.

    Powder paint for model engines

    After half an hour, my toaster oven finally got up to 320 degrees, but I don't think it's going to go up any higher. I may have bought a "pig in a poke" here.

    Powder paint for model engines

    Now it's time to give this toaster oven some more attention. First off, I don't think I should use the timer (bottom dial) at all. The timer has a maximum of about 10 to 15 minutes and then it turns everything off. The second dial/button down from the top has 10, 20, 30, 40, 50, 60 increments...

    Cyclone dust collector

    I ran at 70psi. Didn't try anything lower. Will try at lower pressures as I figure this thing out.---Brian

    Cyclone dust collector

    COMPLETE SUCCESS!!! Sandblaster is awesome. This is an ancient wrench that my father inherited from his father and passed on down to me. I sandblasted the handle in no time flat. It's a bit early to tell how well the cyclone dust collector works, but I will find out as I get more stuff sandblasted.

    Cyclone dust collector

    IT WORKS!!!----Today I installed the sand delivery hose and loaded 5 pounds of media into the sandblasting cabinet. Everything works more or less the way I had hoped for. I have to find something to sand blast now. I haven't tried the dust collector nor vacuum yet but I definitely have a strong...

    Cyclone dust collector

    Today I bought a 50 pound bag of 30-60 Greengrit recycled glass. My choice was influenced by the fact that this particular grit was on sale for $10 per bag. I also finished plumbing in the air pressure line. Tomorrow I will plumb in the sand supply line and hopefully try this system out.---Brian
