Holding thin round stuff
I've got a situation where I have to drill 3 holes, then accurately
cut out a slot in the lid of a small cookie tin. I made the fixture pictured here to do the deed: http://www.flickr.com/photos/steambo...57624880649814 --The trick I came up with: I layed the thing out with a measuring tape, making certain that the center of the round thing was a little over some nice round numbers in X and Y, relative to a reference corner. Once everything was drilled, tapped and fastened in place I put the fixture in the vise with a part mounted. Using a dial indicator that touched the outer rim I found the exact center of the part. I reset my DRO to 0,0 here and then went looking for the edge of the fixture with an edge finder. I marked down the numbers, then milled those two edges to 'round out' the distances. Next time I use the fixture I know the center of the round thing is exactly 6" in X and 2" in Y, instead of some weird number I'd never remember. --Still and all I'm not real happy with the fixture and I'd be interested to know what others may have done in similar situations. I didn't want to go overboard on design since I'm only doing maybe 50 of these and the 'customer' is me. ;-) -- "Steamboat Ed" Haas : Steel, Stainless, Titanium: Hacking the Trailing Edge! : Guaranteed Uncertified Welding! www.nmpproducts.com ---Decks a-wash in a sea of words--- |
