my home made boost comtroller (pics)

ok so i read around and saw that everyone was using 1/4" connectors but my hose was 3/8" so i went with 3/8" MIP, this thing is massive.

Parts list:
1 'T' with all connections female
2 male fittings
1 3/8" MIP to 1/8" FIP connector
1 1.5" 7/16 fine thread bolt (i think it was a 20 pitch)
1 Nut to match above bolt
1 thing, i don't know what exactly it is but i think it came from a closet door. it is spring loaded and supposed to have a plastic piece around it to insert into a hole in the top of the door. the door folds in half.

the last three were free. compliments of laziness at home depot. i found the thing on the floor and the lady was not motivated enough to look up the prices for the nut and bolt. even though i told her the price of them.

what i did, that is not really explained in the pics (in this order).

1.Drilled and tapped the 3/8" MIP to 1/8" FIP connector to accept the bolt.

2.Drilled a hole the size of the door thingie in the center of the bolt.

3.With the door thingie's spring removed, chucked it up in a drill and beveled and tapered the end that goes into the pressurized side. and made the shaft thinner. I made the shaft thinner so i would not bind in the almost centered hole in the bolt.

if you have any questions feel free to ask.

AWESOME thanks!
We have BINS of misc brass fittings at work so I'll rummage thru that and see what I can come up with. as for YOUR controller, are you sure that spring is weak enough to allow that pin to raise at a specified pressure?

my calibrated mouth can push enough pressure to blow though it. and the regulated air on the air compressor can be held back to 30+ psi.

so i would say yes
