Cheap 'n Dirty Chamber Gauge
Another potential Cheap 'n Dirty Chamber Gauge can be made using plastic hulls; RST's, etc. Check out the pictures below.
Make a nice, square cut just in front of the metal base and square up and trim as necessary. If possible, end up with a finished length of 2.0" +/- 1/16" for easier measuring.
Just slide the trimmed, squared off end into the chamber until it stops. Likely, just where the forcing cone begins. The other folded, crimped end will be seen in the chamber.
Then with a machinist's scale, measure how deep into the chamber that hull rests.
Add that measurement to the length of your gauge and you'll have your chamber length.
Works great.
Some pictures below and you can see what they look like. Make set for each gauge. Yeah, Cheap 'n Dirty.
You'll notice that I have my set of 4 threaded on a piece of line. If you'll look real close, it's not an ordinary piece of line. It has a collar crimped at each end.
For you Old Navy Salts, you'll recognize that as a Navy clothes pin. They were issued to us in Navy boot camp back in the early 1950's.
In boot camp, we did our laundry be hand and hung them out on a clothesline to dry. It was required you used as many of those Navy clothes pins as necessary keep your laundry tied to the clothesline.
And it had better be tied on with a square knot. If not, and the company commander found your laundry tied on with a Granny knot, you can expect to see your fresh washed clothes on the ground and stomped on.
Also, for those interested, I show a picture of the Galazan/Jolliff chamber gauge as discussed above. The one shown is Serial Number 1 made back in the 1970's.
