I'm looking to get this shock pump and was wondering if it would attach to a normal schrader valve?

it should, practically all shock pumps I've seen screw on to schraders.

Thanks JSR. Now I can take my copper pneumatic up to high pressures without braking my bike pump every time i try to fill it up.

yeah i have that exact one, it screws right onto shrader valves.

depends how big your chamber is, if it's bigger than a couple of cubic inches then going beyond 250 psi becomes a bit of a chore.

I was going to use the shock pump to top it off to higher pressures. Chamber is only ~4-5 cubic inches. As off right now i can get it up to roughly 200 psi or more with a bike pump. Gauge goes to 160 psi but i can still pump it 5-6 more times and each pump puts between 15-20 psi in.

Edit: HDP how hard is it to pump at higher pressure like between 300-400 psi?

It's a bit of an effort but it usually doesn't take me more than 2 minutes to reach 400 psi.

Why not build your own pump?
I hear BTB has a good design for you.
Should at least go up to 79.9 bar....

I would but i can't locally find a pressure gauge that goes past 200psi. I just found one on ebay that goes to 600psi for only $10. Now to find some hose that can withstand up to 600psi and has an i.d. of i think 1/4" so i can attach a screw on valve depressor.

I'm thinking of shnaffling the schrader connector off the hose on my shock pump.

It vents the hose before releasing and is a nice solid screw-on one.

Looks like a 3-4mm hose tail crimped into the hose though and the compressor hose I've found doesn't have an ID that small

Pressure washers have gauges that go up to 1000 to 2000+pressures....I think they can be used on cannons????

I mean 1000 to 2000 + psi

yes but tht is pressure with water. so 2,000 psi air would need a much better seal on the pressure washur gun. and would need a lot of modding.

Most pressure washer bits won't seal at their rated pressure with gases. I found out the hard way

Still eating at you isn't it! Don't worry, i am sure that you will find a good way to use your immense power (pressure).
