  • Rookie PCer JOB #1

    OK boys & girls, I have just completed Job #1 in my hobby PC operation.
    I have been lurking on this forum and it has been a huge help in getting going.
    HARDWARE:
    Air compressor - 3HP
    Blast booth -home built w/ pressure pot sand feed.
    Gun - Eastwood hobby.
    Dust collector - 2 HP
    Oven - 36x36x52 useable inside -home built.
    JOB #1 Reese hitch parts for my car trailer.
    Procedure:
    Blast to white with 80 grit alum oxide.
    Coat with gloss black powder.
    Cure at 375 PMT for 20 min. (I am catching on to the TLAs (3 letter acronyms))
    Results:
    Generally pleased with things.
    The warts and pimples on the cast and forged steel parts show clearly.
    The chains had areas of no coverage. 'bout what I expected.
    With all the high amperage stuff going, the lights in the village did not go dim. I will need to rewire the shop so I don't need to run a stout extension cord to the wife's clothes dryer receptacle.
    This was the first time for the oven and I believe it worked as intended.

    Now for some things that you may be able help with:
    1/ I get moisture in the air lines that frequently plugs the sand feed. I will review the posts on the coiled copper tube system that looks like a mountain still. Has anyone tried the air dryer from a transport truch air brake system?
    2/ The plastic protectors for the glass in the blast booth dull quickly and are relatively expensive from Princess Auto locally (similar to Harbor Freight). Any suggestions?
    3/ I used approx. 1/4 lb powder on these hitch parts. It looked like ~50% - 80 % did NOT hit the parts. I have no feel for the actual thickness. Any suggestions for a thickness tool?

    Here are some pics. ('hope they load properly)

    I am really slow on the keyboard, so when I get some time I will post details on my home built oven and related hardware.

    Best regards / Bob

          Welcome looks like you got it pretty much
          that thickness guage is a good investment if you can afford one.
          and i think you want a ferrous and non-ferrous guage.

Has anyone tried the air dryer from a transport truch air brake system?Theres good info in those post to help. Do you have any dryers or water traps in you air lines now?
                  2/ The plastic protectors for the glass in the blast booth dull quickly and are relatively expensive from Princess Auto locally (similar to Harbor Freight). Any suggestions?Unfortunately this happens. When blasting try to blast at an angle that will cause your media to deflect anyway from the glass this will make your films last longer.
                  3/ I used approx. 1/4 lb powder on these hitch parts. It looked like ~50% - 80 % did NOT hit the parts. I have no feel for the actual thickness. Any suggestions for a thickness tool? I too have a EW hobby gun it's what I started with. For the parts you did I would say thats not a bad amount of powder to go through. Makes sure your parts are grounded good for best powder attraction.

                      Everyone, thanks for the warm welcome to the forum...'really appreciate it.
                      Whistler & Crimson, yes, Canadian, just outside Woodstock Ontario.
                      zx10, thanks, a good gauge is on my list. In a pinch I can use one at my 8-5 but it is ferrous only.
                      Harley, thanks for the data. I have a simple moisture trap but I believe I need a real dryer.

                      A few more questions:
                      I want to get going on several sets of wheels, steel & alum.
                      1/ Anyone use iron phosphate treatment? Spray? Dip? Warm?
                      2/ Anyone use de-ionized water rince?
                      3/ Is PBTB bio-degradable stripper the best bet? 'probably need half a drum.
                      4/ For brake calipers, can I cheat and leave the seals in? They should be high temp material that would readily survive 400F.

                      Thanks again / Bob

                        Question 4: I'll answer yes. Most guys on here don't recommend it, but I've done Brembos that way with no problems. If you plan on rebuilding them anyway, I would definitely leave them in and do the rebuild after coating.

                        Best of luck.
