Air gun perhaps, I can't envision the threads supporting 'spin'.

Sorry, I was trying to help an individual who could not afford a new tank, If the screw does let go its going down and then hitting the wall, when your trained to improvise its amazing what you can do in life. I was not offended, to old for that. Still enjoying the site and helping where possible.

The stars, the employment schedule, and the weather were all in my favor today, and I finally got a coat of grey on Tony Wells air receiver!

It's sitting under the A frame waiting on him now.

And pick it up I did, that evening. Jake also pitched in some expanded metal and angle to build the belt guard. Many thanks for the great job!

Now all I have to do is put all the bits and pieces back on it. Jake was kind enough to toss in the one piece I had that was missing (more or less) the air cleaner. The one that was on it was kludged together by one of the PO's. This is an older compressor, marketed by Sears commercial division probably back in the 60's. It is a Kellog American pump, 2 stage, old and slow 5 hp. I have the original motor, but am updating to a newer more efficient TEFC 1.15 SF 3 phase 5 hp. About the only think I will have to track down is the dual, matched drive belts.

Just a word of caution on repairing a rusted out air tank. When I was still working I had to go through routine inspections on all of our air vessels and have them certified by a state inspector. He told my a story about a good friend of his whom was also an inspector for the state.
About two months short of his friends retirement, he was killed. He was doing an inspection at a plant in Minnesota and while walking by an air tank, a patch which had been welded on let go. The projectile went right through his head, killing him on the spot.
After I went home that day, I went to my sons home and proceeded to drill a series of holes through a tank that I had repaired, rendering the tank useless. Guys, do not repair an air tank. It is not worth risking your life over the price of a tank.

I knew a guy who drove an old rusty (brand doesn't matter) pickup, with holes in the fuel tank. He worked at an industrial fastener house, and used self tapping sheet metal screws with sealing washers, common on roofs and metal building siding, etc. to "patch" it. I think in 2 years, he had about 10 of them in the bottom of the tank. Worked great.......for a gas tank. For a pressure vessel, different deal totally. If you think that pinhole is the only thin spot, you are probably fooling yourself. It just happens to be the thinnest spot. Chances are, the mode of ultimate failure would be simply to eject the screw (bad enough if you happen to be in the "line of fire"), but putting a screw in a rusted out tank can't be a wise idea. The second thinnest spot, even if the screw holds, could be in a critical area that could fail in a catastrophic manner. I'm usually not opposed to calculated risks, but some risks are not so simple to calculate, and the consequences are potentially deadly in this case. I will add my voice to condemnation of the tank.

I fabricated some brackets for mounting a better air filter to my mower. The normal ones tend to be "good enough", but with adding a bagging system that is directly in front of it, a lot more dirt/dust will get thrown in the air right by the filter. The filter is a Donaldson 2-stage filter, that I bought for my Gravely Zero Turn mower, which I'll probably sell now.

I bought the air intake off ebay, it's for the version of this Kohler engine that comes with this Donaldson-style air filter setup, just had to make some studs to mount it on (it sticks out about 2" more than the original air filter intake did).

The original bits that now go into cold storage:


The new bits on the mower drive unit (this is the same one that I made a plow attachment for):


As a bonus, this will also prevent me from stupidly using the top of the engine as a brace while it's running. The screen isn't too bad, but there are 4 bolt heads that both remove skin and damage the muscles underneath...

The brackets are now in the paint booth.

Very nice! Should be easy to get out of the way if needed.

For the last two days I have been making piles of HDPE chips.

Making these fishing rod holder brackets for a customer. These start out as a 48 x 96 x 1 sheet of HDPE, takes about 13 hours per sheet to carve them out on the router. There is one operation that takes 8 hours, so I start it at night, then just go to bed. It's done in the morning when I get up. Nothing like getting paid to sleep. Around $1000 per sheet for the material.

Yes, the adjust-ability is a nice feature. I've never used a shield on mine, but I could see something like that being used under certain conditions. Have tried looking through a windshield on motorcycles, and could never get used to it. Mike
