Hi All,

Here is the steel launcher almost finished and the PVC launcher repaired after the 120psi sch30 oops.

Please be careful of shcedule 30 past 80psi. This is what happened to mine at 120psi. It held the pressure until just before I was pushing the trigger switch. I had accidently purchased sch30 instead of sch40 and didn't realize until the expolsion. Thankf

Someone had mixed the sch30 in the sch 40 pile, still my fault for not double checking. Luckily no injuries.

Not really sure. It can handle all my 5hp shop compressor can push in it, 165psi. I need to get a scuba tank and test it.

Yeah, I will use a reg from one of the argon tanks on the welders. I do appreciate any saftey tip wether I know it or not. High psi is extremely dangerous, even if everything is 100%.
