Anyone know where you can purchase a go-nogo plate thickness gage? You slip it over the edge of the plate or bar stock and can quickly verify the thickness(ie verifying 1/4 vs 5/16, the plate won't slip into the 1/4" slot if the plate is 5/16" thick)
The one I have says Robinaire - USA on it.
Here is a pic to help explain what I have.
I have a couple of those except they are round. I believe I got them from my local steel supplier. I think I have seen them in MSC catalog as well.
I'll see if I can find a name on it when I get to the shop tonight.

I looked in the McMaster-Carr cat. and found something similar but not exactly like it(they called it an all-in-one gage and checks pipe/bolts/other items).
This one is made of metal so that you wouldn't wear it out by checking alot of plate with it. I'd be hesitant to buy a plastic one because it might not last very long.
When I visit my local steel warehouse, they break out a set of dial calipers to check with. Not even going to go there...a set of those wouldn't last a few hours in the shop. I keep my set in my file cabinent where it is safer....LOL
I'm pretty sure mine go from about 22 gauge all the way to 1/2". If I need to be real precise I use the dial calipers but usually either a tape measure or the slip gauge.

I've seen the round tool for gage materials in McMaster-Carr, only problem with that one is that it stops before it gets into flat bar sizes that we often use. Quickly ID'ing a piece of 5/16 or 1/4 is my main goal, with a tapeline they both measure 1/4" and difficult to tell quickly at a glance.
As for the other suggestion, I have a UT machine with straight beam transducers already and it would work, but I wouldn't trust the guys on the floor to take care of it like I do and that thing is about $10K new.
I may have to just make a few of them on an end mill, if I can't find them in production any longer.
>Us old timers just pinch the steel and feel how thick it is
LOL, I was one of those oldtimers until I was fooled yesterday.....
One of your friends with a laser table must owe you a favor ??
Have them make you a batch :)
We make a lot of transition gages etc with our lasers
John just how long have you had this gauge, if you fine another one like that one I would like to know where I could get one myself.
I'm not sure when we received it, it has been in a desk drawer here in our detail material department for several years.
I've look for one on the internet last night for a little while and couldn't fine one, but I well keep looking the one I have goes to .3125 or 5/16 but the one you have went up to a .500 didn't it.
