doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Help With Manson Wall Thickness Gauge

Hi all, I just got (used) a Manson WTG, but with no instructions. I know that Mike posted some pics on this, but I was wondering if I could get some instructions (in plain english). The e-mailed instrctions from Manson, are not the best without the pics.

So......help please!

All the best!

I can try to help you if you want to use it in the horizontal position.

Put the assembled gun upside down on a table. Extend the barrels about 18" over the end of the table.

Hang one tyne of the fork in the barrel. Hang the tyne that goes in the barrel, not the one with the dial gauge. Adjust the dial gauge until it reads zero.

Push the gauge into the barrel and read the wall thickness on the dial gauge as it goes down the barrel.

This is how to do it with the Truth Tool. The Manson may be different in some details.

Best,

Mike

This picture shows the tyne hung in the end of the barrel: Notice that the left end of the gauge hangs from my thumb so that I don't torque it and mis adjust the zero point.

This picture shows that the gauge reads zero after it is adjusted. This is before you start taking measurements:



Then you slide the forks down the barrel and read the thickness:


Clear as mud I am sure. Good luck.

Mike

I like to hang the outer end on a string or wire to ensure that I don't torque the setup in any way.
AND the prong inside the barrel must NOT touch the barrel except with the ball on the end!

Does anyone know where if there is a stand up wtg that is as reasonably priced as the mason?

I just can't see why this can't be done with lasers, mass produced and sold inexpensively. Or......ultrasound. I may work on that.

Hi all, Thanks Mike!!!! I think I got it, but I do have a couple more questions.

When you put the fork in the bbl to read, do you let it touch any of bbl wall? From the pic it looks like you don't.

Also, I have the model with the plastic reinforcer. What's the right way to use this device?

OSF, great tip on the string!!! My unit weighs a ton and this idea sure helps.

Thanks again for all the help!

Greg

No, only the ball.

I don't know what the plastic reinforcer is.

And you are very welcome.

I hang mine on a heavy cord, from the ceiling, hanging over two screw-in hooks. The dial indicator is down. By sliding the barrel(s) up the ball and shaft, this puts very little side pressure on the gauge. Gives the most accurate readings, IME. I also added a wire tensioner to help maintain tension against the probe. Rabbit has one similar to mine. Maybe he will post some pictures.

Are you talking about the white bock that slips over the two rods? That is only used in shipping to prevent damage to the rods.
