I use a NAPA "SpeedBlaster". It was about $45 several years ago and may still be available.
At the time I had limited space and it seemed the way to go. It is a gun with a mounted
canister similar to a paintball gun. The hassle is the regular filling when blasting large parts.
I also use "fine" sand in 80 lb. bags found at any lumber yard. It runs about $8 a bag compared to more expensive media. At that price, I didn't care about recovering for reuse.
I have been into this for three years now. I am home only about 4 months a year so it will take a while. I saved a lot of time by having the engine overhauled ($388.00) and just picked up my overhauled transaxle ($400.26) The transaxle needed some gears, seals, bearings, gasket, etc., all of which were eventually located. Costly, but confident the Jake will be around another 45 years!
I began wanting to only make the tractor mechanically sound but thought at the extent it was dismantled I would regret not putting "lip stick" on it! The original paint is available but at $12.00 per can...it was not an easy decision.
It's just taken determination and an understanding wife!
