sand blasting cabinet, go big or go home

[pjtoledo]

standard sized cabinet, 16"wheel is difficult to do.

I have a 48x36x24 cabinet you can have if you pick it up...

Time to build your own cabinet.....
One you can walk around inside.....
A couple of BB 460's with half the cylinders used for compressed air.....
A dump truck to haul the sand....

I once saw a gravity flow grain wagon that had been converted in to a sand blaster cabinet. It was really kind of ingenious. He could fit nearly all tractor parts in for his restorations. Had a platform around it to walk on, and gloves on all sides. Extension sticks to get the blaster nozzle closer to all the parts, and some nozzles that were very long. The sand poured out of the bottom to reuse.

thanks for the offer, don't think the logistics will work out. I'm at the western end of Lake Erie.

kind of working on it.

I'll stay outside.

problem is the valves. need exhaust valves that don't open until full tank pressure or the tank will "refill" the cylinder
before the cylinder fills the tank.

Hmmm,, hinges easy to do. can use the ram from an engine hoist to raise it. throw on some cobbled up duallies
and swap in a 2.9 for MORE POWAA

Just find a 1st gen with a bad 2.9, remove interior, cut glove holes in a door and blast away. Easy peasy

Semi-serious?...how about a belt driven supercharger with the outlet feeding your compressor tank?

May or may not help but some marine engines spin the wrong way, the cam may help your cause.

or maybe messing with the cam to crank timing

make sure it isn’t an interference engine though...

You jest, but GWAII did it. Might have been a 2.8L, but it was same basic engine he converted to an air compressor for his tarp garage. Wander how the GT-12 is coming along.

I suspect there is a big difference in sealing between 15-20 lbs of boost and 150 lbs of boost.
a standard piston compressor has very low loss.

recently I thought about doing that with a 3.0
since the compression and power strokes are wasted you should add lobes on the other side of the cam to kind of convert it into a 2 stroke.
and get rid of valve overlap.
then there is the issue of opening the exhaust valve when there is no pressure in the cylinder. the already pressurized tank isn't gonna waste any time back filling the cylinder. some check valves should fix that. but those would be outside of the head. which means you would have to pressurize the cylinder and the exhaust port before any air would get past the check valve.
of course you could get a pseudo head torque plate (a thin one) and affix the check valves and plumbing to it.

all this considered, it was much easier, and probably cheaper, to buy a 3.7 hp compressor.

It's somewhat common to turn engines into compressors, or it used to be, I have a Grimmer Shmidt or something like that in my driveway that I got for $50 at an auction... it's a 302 Ford set up to run off of propane on one side of the engine, half the spark plug wires are grounded, the compressor head connects to the engine block and blocks off those 4 intake ports on the intake manifold, there's 4 reed valves on that side and it has it's own air filter. I believe it is rated for 75cfm at 90psi if I remember right, it has an air governor on the throttle.

We've done similar at work, engines care much less than you would think when you cap off half their cylinders... If you get bored sometime, unplug half the fuel injectors and take off half the push rods and rockers from an engine, leave the spark plugs in, it'll shake a little at first but once the air volume in the cylinders figure out what they want to do they run smoother than you would think... much better if you had just taken out one push rod or pulled the spark plugs out.
