ferret! dude! I think that just might be what I needed. we'll all find out before too long. thanks!

that's what I tend to do when I have the time and materials for it. I'm better at thinking that way than semi-abstract 3d type stuff.

not good at multi-tasking? I have enough probs single-tasking! *L*

Drac, there is a formula for this, what it is I don't know, but a friend of mine who is an engineer did some patterns for me a few years ago told me all about it but of course I forgot! I do remember he said that you need a set of trammels to do the drawings.

Hey Drac,

For some reason I thought it was something like this.

Have your top dimension's straight line (24) find the center and draw a line 1/2" down. Draw your bottom line (17 1/2) find the center and draw a line 3/4" down. The end of the lines you drew down will be your midpoint for your radius'. I think I saw this on a tut. for making arm bracers. What do you think?

Should be close enough for most purposes. It all depends on how precise you need to be.

just a thought, do you have plastic plant pots over there? could save doing all that jometree stuff

yeah, that would work IF you can find 2 of the right size. put them bottom to bottom, then cut off one bottom to make the height correct, glue together & you have the proper top & bottom curvatures. wrap the cardboard around the top & bottom, tape, trim top & bottom & then scribe the center joint line & cut down the middle. good one, ferrett!

Alternative B: Go down to the local Motorcycle Shop, buy a pair of gauntlet gloves that are close to if not what you what, disassemble and use as a pattern.

only problem with that is I'm not doing gauntlets. just used 'em as a reference to be more clear about what info I needed. it's for a special project. and nope! not gonna say what until it's done. you can't make me. nosiree bob! my lips are sealed!

[Beaverslayer]

I'm pretty sure with a few well placed electrical devices we could get some info outta ya....LOL

It's stuff like this that makes you shake your head for not paying more attention in math class. I'm with Bill, I've spent a fair bit of money on things just to tear em apart, I've got a "Long Riders" coat that I payed $350.00 for, and still have not found the time to make it out of leather...one day soon.

well, the one site didn't help after all. couldn't figure out where they got one value. did find this one though! http://jwilson.coe.uga.edu/EMT725/CarlCone...utionPaula.html

at the bottom of the page is a link to a spreadsheet that figures it out once you put in certain values which you'll have already if you're gonna do one of these. looks like it'll work. I should know in the day day or two. w00t!
