Hi, The motor is from a washing machine, so around 1/2 HP. The tank has a diameter of 15" going to a 2" pulley on the midshaft with a washing machine motor pulley of 14" which then terminates at the motor's 1" pulley. I think the motor is running full speed at 1400 rpm, dropped down to tumble the drum at 30 or so rpm.
I rotated for 2 hours horizontal (1hr each clockwise, 1hr anticlockwise) Then tipped one side up so the level of the water reached just below the end holes and ran for an hour for each side.
@@bootsowen a shame one of the large ends had been cross threaded in it's previous life. New fitting couldn't get a seal even after cleaning threads with a thread file. New tank bought which I want to have galvanised before putting into service. Lots of people say just use it and replace when necessary, but these people have large disposable incomes.
@@bootsowen certainly a possibility. The end caps at this size (1.5" BSP) are cast steel/iron so not sure about welding. Perhaps braze it on. I've since bought a new tank (150L £360) and had it galvanised (£100).
Hi Larry, used some pea gravel as shown in another video on TH-cam: pSFr4hJZPn0 Seemed to clean quite well inside but showed some pitting in places that appeared to be 50% of the thickness of the tank. I think the tanks are likely to slow leak rather than explode. I couldn't reuse this as one of the end caps had been cross threaded and wouldnt seal when pressure testing it.
@@ianhelsbyservices They don't slowly leak., they explode. There are plenty of videos about compressor tanks explosions. Check this one out... th-cam.com/video/sm_FJ6Pat4I/w-d-xo.html
Hahaha yeah bro totally, I love rust contamination in my air, and buying expensive filters to frequently replace, just to remove the rust contamination coming from the tank itself!! Probably no one exists using compressed air for anything that requires clean air because I don't!!
NICE!!!! I LOVE THE ENGINEERING!!
Tricky as you've gotta use wheels/rollers with a large diameter to clear the swinging bits!
Looks like a good way to apply a rust barrier inside.
That's some Fred Flintstone engineering there works excellent, You like me probably had the master tinker toy set

Pretty Cool! Love the ingenuity.
What kind of motor did you use?
HP?
RPM?
Good job.
Thanks.

Hi,

That's good for cleaning the sides, what about the ends?
I rotated for 2 hours horizontal (1hr each clockwise, 1hr anticlockwise) Then tipped one side up so the level of the water reached just below the end holes and ran for an hour for each side.
This is a pretty epic device Ian. Space and time are the only things that we need in life! The rest falls into place.

@@ianhelsbyservices if it’s a choice between throwing it out because of the crossed threads why not just weld it? Or have it welded?
@@bootsowen certainly a possibility. The end caps at this size (1.5" BSP) are cast steel/iron so not sure about welding. Perhaps braze it on.

What media did you use?

Probably an idea to screw the new end on as far as I can to the bad threads then braze it in place permanently.

You could roast some nuts in it.. otherwise it is the dumbest thing ever haha
