On eBay there is currently a thickness gauge that looks simple enough to build. Does anyone have a drawing for making one?

There are a bunch of homemade ones in various threads here, Jim, but I don't know that anybody every broke a thread out about them, so this is good - You might look here for starters:

Also, Grizzly has many variations from manual to gauge that are cheap and work quite well - I got a caliper style thingus from them that has around 5" of reach...

Bob Benedetto has a homemade one in his book that looks pretty slick.
Doesn't look like it would be very hard to make.

Hi Jim,

I made one that looks kinda like that one on Ebay, but simpler. Same 2 pieces of wood, but then I put a T-nut in the wood directly below the gauge arm, and used a (round headed) stove bolt. I cut a slot in the bottom of the bolt, so I could turn it with a screwdriver, and I purposely damaged the bolt threads a bit so the bolt would not move on its own. Once you spin the bolt to barely make contact with the gauge arm, (and zero out the gauge), you're ready to measure. It's easy enough to pick up the gauge arm and slide the wood in, so I don't think the fulcrum lift lever to raise the gauge arm is necessary.

Here is the thickness gauge I have been using.

This one is simple - easily made and easy to use.

And here is mine.

The dial guages are very inexpensive to buy. I prefer this system where the instrument is stationary and you manipulate the top through it as opposed to a hand held. To each his own!

I've seen very good prices for those little guys at MSC, Grizzly, and the Iturra catalogue - Might just have to spring for one - That's very elegant, Greg, and looks downright sturdy, too!

Sometimes I get inspired. It didn't take any longer to make it look nice than it would have to do it basic. It's interesting though, it is very sturdy but the dial guage will vary by 15-20 thousandths throughout the year due to changes in RH.

Greg,

We are working with wood ! laugh.gif

I like the dial guage type read-out but would much prefer it to have much courser calibrations.

I do like the idea of not needing to pick the guage up for each reading though.

Someone here on the Forum showed us a shop made guage that was mounted on the wall. That one looked interesting too.

Thanks for all the help and suggestions.

Steve's and Greg's look great for thicknessing carved top and backs. My newbie concern is that once I get my top and back to the proper thickness, what is happening to their thickness when I sand them after joining them to the sides? I had to do a lot of scraping and sanding on my first guitar, and I worried about making it too thin. I need something to slip into the soundhole. I don't have the Benedetto book and I couldn't find anything in the jigs forum that Eben mentioned. I guess I better buy the book. huh.gif

Jim,

I remember seeing a magnet based rig that will work on assembled instruments.

Found it is a recently expired catalog -

Hacklinger Thickness Guage - WOW ! Ain't cheap either ! $385.00.

Guess we could live without that one.

Eben,

Thanks, think I'll take you up on your generous offer. I will follow Steve's suggestion as soon as the Lottery check comes in!!! laugh.gif

You can PM me or post if for everybody, which might stretch the copyright laws.
