    Anyone willing to share their designs for shop made thickness calipers and pros and cons on the subject? I believe there was a thread some time back but I haven't been able to locate it in archives. Thanks!

    Iíve posted this before but hereís the one I made. I used a Sears depth gauge (about $30) and some scrap Mahogany. It works great and Iíve made many tops and backs with it.

    I have made one as well, from scrap maple, but it really doesn't have any benefits over Gail's, so I'll be lazy and skip the pictures. I did, however, get the dial from Harbor Freight for $6.99, and it's been plenty accurate (100th).

    We just use old loop style calipers, with inscribed lines only to the thicknesses we normally use.. it helps not having to look at all those little lines, although I like the look of the sewing machines all you ladys made..

    Thanks guys, and you too Luther! I'm always entertained by your levity. By the way, I used to own a Randy Wood A model back in 74-75 when my 24 Loar had been stolen and later returned. Was a great little mando.

    I don't know Darryl...there's something about making your own that just seems like good karma...

    Hi,
    Here's a caliper that I just made yesterday. #It's made out of 3/4 in. plywood and has a detatchable base. #Total cost, about $13 for the dial gauge and the rest was scrap laying around.

    Just picked up dial guage at Harbor Freight for $13. Official name is '1" Travel Machinist's Dial Indicator'.
    Now I can go to work and throw something together. Thanks for everyone's input!

    Craig, that dial indicator is probably in thousandths of inch. Most plate maps I know of are in mm. It's easy to convert in your head, keep in mind that 1 mm = .040"

    Hey Michael,

    What's up with your site? I tried to steal a pickguard image to post in another forum here under my favorite pickguard but couldn't get the site to come up...

    That's a sad thing for me as I look at several times a week for inspiration...

    I did mine out of dumpster scrap, and a desire to not look at ugly plywood.

    Ellie, An irrepressible sence of style just can't be hidden.

    Enjoyed seeing the Jessica Rabbit mando in Tacoma.

    If you want to build one really cheap and 1/32nd of an inch is accurate enough then you could build one like I did. This is just a 3' Lufkin tape measure that measures to the 32nd of an inch.
    1 inch is my starting point instead of 0. The spring action of the tape measure is enough to return it to zero (one).
    Cost was $2.07 for the tape and my time and some scrap maple, glues and screws

    Thats great, when I first looked at it I thought it was a joke. Then I looked closer and thought "it probably works".

    I purchased the Harbor freight dial for $6.99 that will measure the thickness of paper. I made my whole device in half an hour. Stew-Mac can keep their $159 one.

    Jim, hopefully that will take you to the dial gauge.
    If not let me know.

    Strange, but I can't get on the Harbor Freight site at all, now. They must be having some sort of problems. I will try again later or tomorrow.

    Great thread! Thanks a million to all, this answered a lot of questions for me as far as planing/sanding accurately the top and bottom.

    I was finally able to get on the Harbor Freight site. There are two dial indicators both for $13.99 (none that I can find for $6.99):

    1" Travel Machinist's Dial Indicator

    1" Dial Indicator

    Then there is this Jeweled Dial Test Indicator for $29.99.

    Any clue as to which one is better?
