My models are more realistic than your memory! :D :D :D

Where should I post the 1 inch QDV?

Do you want it in this posting and the sketchup library?
The locations sound great. I'm sure others will be interested in the fine details. I'm glad you found the exact tank so you got the model correct.

This will be added to he library once Tech approves dimensions.

Edit; removed attachment.

I am glad you requested verification. The flat end is the breech end. The rounded end and the end with the recess are the same end, the muzzle end. Other than that minor detail, it's fantastic.

The bevel is to narrow the edge between the ring and end of piston and provide a smooth transition from the chamber to the barrel.

Here is the revised drawing.
The previous one will be deleted to prevent confusion.
This is a 2D version (top view). Use for accurate dimensions.

Tech can give approval.

I am very impressed. One comment on the tank. I wanted everything serviceable without cutting. The Schrader is only a 1/4 inch close nipple. The schrader or quick connect for rapid fire is screwed onto the nipple.

That can done!

1/4" nipple brazed/welded.

The disconnect, is it ARO or Industrial?

I could put a 3/8 to 1/4 hex bushing in, then it is completely changeable to any combinations. It can be Schrader or any disconnect the builder wants.

Seem like a better option to me.

The coupling is industrial. You could put in a bushing, but the original is simply a galvanized 1/4 inch pipe nipple. Well it was galvanized until I got it to brazing temperature. :D

The schrader is simply a tire valve with the rubber cut down some and then put in a brass 1/4 inch pipe cap and screwed on. With the rubber, no tape or other sealer is needed.

When I went to Arlington with the full size, they used another coupler so using their compressor was a mater of simply borrowing a fitting to fit. I later bought one. They are under $2 for the male. I keep a selection in my bag for traveling.

I took the fill valve measurements. See photo. The tire valve was turned down in a drill press to fit the hole in the cap. I left a shoulder on the valve just small enough to fit inside the 1/4 inch cap with a little pushing. The shoulder is only about 1/8th inch long. The rubber was trimmed flush with the end of the brass tube inside the rubber. The brass tube overall length is in the picture. This rubber shoulder provides a seal on the 1/4 inch pipe nipple without requiring any Teflon tape on the threads. It screws on airtight.

I bumped this so dewey would get the measurements for his library.

Whoa, those are awesome. They beat the hell out of the dummy models I faked in. Those could be used for some sick renderings.

Thanks. I try to model as close as possible to the real thing.
Damn near wear out my dal calipers with all these models!

I will e-mail you the sat files later.

Here is a tire valve stem TR 413 for those of you that use this type.

The modified one is Tech's version. 3/8 inch hole in 1/4 inch brass cap.
The rubber is trimmed to fit cap thus giving it a compression seal when tightened onto pipe/fitting.

I will be adding other types later. (Metal Clamping Type TR 416B)
