.40 Cal 2

<div align="center">.40 CAL 2
Provided By - dmt4595

I have my version of robbie's .40 cal gun almost finished and working. I still need to make the stock, and i still need to find a good schrader valve - the one i have is from a bike tire epoxied in - it works fine, but the pressure guage has a pinhole leak. I also need to finish modding my sprinkler valve - it works fine, but i forget how to make it work without leaving the solenoid screwed in - something about epoxy in the holes, but i dont remember which holes to fill lol. I should have pictures up in a little bit if my brother is nice to me..

I also went out and bought a 4' long steel rod today at lowes to use as a ram rod... i just found out that the tail of the metal tipped stun darts is a perfect fit for the rod, so naturally i made some darts. (the rod was 1/8" steel welding rod) right now i only have 2, i dont want to waste too many of the stun darts that i bought, so until i buy some more tails for them, i will only have maybe 5 hunting darts tops. (and when i say hunting, i dont mean i am going to shoot them at living things - im not that stupid) i tested one of the darts out at a cardboard box filled with old magazines at 25 psi - went through 4 and the tip was lodged in the 5th - with plenty of shaft not even into the first magazine yet.

you'd have to use calipers to measure the OD of the blowgun pipe, all of them are different

Never use DWV, it has to be SCH40, DWV (drain waster vent) are for gravity flow, they aer not stable for a air gun AT ALL. Really noce gun, very clean.

Check a hardware store, I believe I have seen schrader valves before at one near where I live. It had a very nice screw connection on the end, will definitely be better than one salvaged from a bike tube.

I've found that auto parts stores are the best source for the threaded schraders. They are typically used in higher pressure applications than standard automotive and therefore a bit of a speciality item. They hold pressure well without being jb welded in the hole so they're very reusable from project to project. Around here they run about $6 each so recycling is important to tightwads like me.

People also seem to not to know how to spell WHAT!! Unless "WAT" is a new short form of the word. Looks stupid, though.

BoomerGer said that.......(Watch out...I'm gonna fart!)
