Pressure Casting Equipment

One side of the garage. It required a day of cleaning up and a dump run to get it to this state of usability. Note the big red compressor that is actually older than I am.
workshop2.jpg
And here's my area. Pressure pot in the middle. Vacuum pump on the left. Casting supplies on the right.
workshop3.jpg
Here's the pressure pot connection details. It's a bit of a Heath Robinson as the fittings were mostly scrounged from the depths of Dad's store room. But it does the job. The reason for the complexity is because of the dual use for both pressure and vacuum.

Top of the pressure pot. See the pressure and vacuum gauges (left and right respectively).

Whilst I was feeling snap-happy I decided to take a picture of my modelling workbench. It's pretty messy but I blame that on the fact that there's always plastic dust and crap everywhere. We can't all model without sandpaper and have a spotless work desk like Seb does!

I think the steel pipe is better to use in the fitting because it is more durable compared to the copper pipe. I tried this at home and it is effective. I commend you try it too.

Copper is most likely going to be fine for this - IIRC most cheap fittings are brass anyway (chrome plated).
Oh yeah I can make that....

Love the post! thanks for the info!
how did you block up the suction tube from the original paint setup by the way?

if i bought a similar pressure pot from ebay would there be any way i could get more info on how to rig up the dual setup from you? i.e. what parts/valves are needed etc? or would you sell a kit for that setup?

Thanks so much! sorry im totally new to this!

haha dad jokes!

sorry yep! so it sort of directs the air up to the top of the pressure pot instead of blowing it straight down!

a cpu baffle might work well can pick them up very cheap on ebay


so is the gauge at the top of the yellow hose air or vacuum?

I cheaped out and did things a little weird with that gauge. That is the pressure gauge - it's on the same line as the yellow pressure line coming in. I did this because I didn't want to pay for an expensive 2-way valve to select which gauge to use (vacuum or pressure). It's not the best position for it as it gets cut off when the air in valve is closed.
