    trailer painting

    Depends on the appearance you want and how long you want the paint to last. If you want it to really last strip the paint down to the bare metal and use an epoxy primer. Then topcoat with automotive paint. If you just want to spruce it up a little wash it good and then use a knotted wire wheel...

    Valve spring question ??

    It would be the wrong spring for the engine. I would think the spring pressure could be wrong would affect how the spring would function. Too weak and the valve would leak or too strong and it would add additional wear on the camshaft.

    Another junk tool?

    Do you think it's a good sign?, the oil in my vacuum never got cloudy.

    Another junk tool?

    At least the electric pump I purchased is pulling more than the pneumatic pump I had. The best it could do is 22 inches where the electric one is pulling 29 inches. I had no idea they run that hot and I think the one I bought runs hotter than most so I'm limiting the run time to about 10...

    Another junk tool?

    The micron gauge would be nice but at that price pretty forbidding for the DIY. The most I could do is empty a bottle of argon and have it charged with nitrogen. I still wouldn't have the micron gauge to manage it.

    Another junk tool?

    There is a fan in the back of it but there is little or no air blowing. It's just flat fins parallel to the motor shaft. The body of the motor is all solid with the pump on the front. There isn't a way air could pass through it anyway. Nothing like a typical electric motor.

    Another junk tool?

    I've been working with air compressors and machinery all my life. Usually when a tool gets excessively hot the motor locks up and quits. I don't have a way to measure the temperature but I suspect after running it 15 minutes it's in excess of 200 degrees.

    Another junk tool?

    I tried the dye first and it didn't reveal the leak. On one of the vehicle I added a couple ounces of fluid directly to the compressor. The other one I installed a new compressor which had oil added to it when it was installed. I know the system is now sealed, both vehicles I charged with 50...

    Another junk tool?

    I had a very minor leak I couldn't find. Using the vacuum pump only let me know I had a leak which I already knew. I was having to charge the system every couple weeks. Using compressed air I was able to put soapy water on all the joints until I found it. I don't have the equipment to flush the...

    Another junk tool?

    That's some system. I think in my case, one car there wouldn't be enough R-12 left in the system to hurt anything. The AC hadn't been used in 10 years or more because the compressor went out. I had to install a new compressor and convert it to 134. I found the evaporator had a leak so I had that...

    Another junk tool?

    I never heard of the word micron in refrigeration before. The gauges I have show both vehicles I'm working on a negative 28. According to google that is 7,112 microns. I think I have it ready to charge, for the first time since I've worked on it, I think I've found all the leaks. I put 50 psi...

    Is it plumb or is it level

    I just moved the hose to a different spot on the wall and back. No water was lost and the hose didn't get pinched.

    Is it plumb or is it level

    I thought so too but I put the water level up against the wall I was building and took it down and put it back in the same spot later and it showed almost a quarter of an inch difference. I thought it would be better than the transit level I was using because I was having a difficult time...

    Another junk tool?

    That is what I have. The problem I had is the cycling switch needed to go on the port on the back side. There is less than 2" space between the accumulator and the firewall so I had to cap that off and put the cycling switch on the front where the charging port is shown. I had to have a...

    Is it plumb or is it level

    I bought a water level to double check a block wall I was building and found it wasn't within a quarter of an inch of level. I went back to using a transit level. Of course under a house you couldn't use a transit level.
