Manson Gauge Question?

[Bob Brown]

Thanks for the info, Bill. I found the threads and links to the YouTube videos on the Double Gun site that you mentioned. Great info and answered questions I didn't know enough to ask yet. I googled the ProCheck model 502702 and didn't find any matches. Couldn't even find the ProCheck company website. One answer that I may have missed from your threads was "is the gauge a 0.0" to 1" or 0.0" to 0.5"?" Looks like a 1" stem but I'd like to be sure before I order a gauge.
I also picked up a four gauge Custom Shooting Products bore diameter micrometer, so more to play with and learn from. Too bad they didn't make those in 10, 12, 16, and 20 gauge kits. I don't have or run into many 28s or .410s.

A Manson wall thickness gauge is a Manson wall thickness gauge. I'm sure the travel on the mic is way less than an inch. I apologize for the doublegunshop.com threads where I tried to be helpful to people who did not understand the use of the instrument. I met some of the most impolite and nasty people I have ever met in the gun world or on a website. To be honest, the worst of them were posting from the UK. They had their own agenda and did not want anyone to help them. To this day, I know that they are buying bad guns and are trying to hang their Manson gauges from the rafters of auction houses because "John Hosford can't tell me how to use a WT gauge." The conversation on the PGCA site was much more intelligent.

A more accurate assessment could not be stated. You have my second Mr. Murphy. The PGCA site is in a class by itself. And I do mean class.

I think you will find that almost all 1" travel dial indicators will work. The barrel diameter is pretty much standard. Ordinarily you wouldn't even need a 1" travel gauge, except the barrel length is proportional to the travel, and a shorter barrel won't work.

Edgar, we're talking wall thickness gauges. No wall thickness needs anywhere near 1/2" or 1" travel. Thanks so much to John Campbell and others for recognizing that Mr. Murphy is trying to assist other posters and the doublegunshop posters were not receptive and in fact quite impolite. Yup, PGCA is a friendly group. Bob Brown is a man of my own taste. He can't own enough measuring devices. My favorite bore mic is the five gauge set that Galazan sells, or did sell, for about $500. With a little modification, it will measure 28 to 8 gauge. In its factory condition, it will measure 28 to 10. I bought one at a gun show for much less, but it beats a pair of Skeet's micrometers, which won't measure a ten gauge. However, I still own my pair of Skeet's mics which I bought from Tony.

Bill, You obviously misunderstood my post. Let me try again, and I'll go slow for you.
Please see the picture, and notice the barrel length of these two 1" travel dial indicators. IF you use a gauge with a shorter length of travel, the barrel will also be shorter, and when clamped into the head of the wall Thickness gauge, the probe tip will not reach the ball. There are long probe indicators available, but much more money than the standard, off the shelf gauge.
YES, BILL, I understand you don't need the 1" of travel, but you need the 1" gauge to fit the rest of the fixture.
