G'day Bob,
' Shop made jigs ' is always an interesting thread . Thanks to all who have posted .
These are just a few I've come up with:
Here's my version of the " Robo Sander ".Made the bottom " Robo " part out of Tas. Myrtle ( not Tiger

). Gives a bigger table than the Stewmac ,and living in Australia (postage ),saved a small fortune , although I did buy their slide vise pictured.
The drum is wood . which I have trued up ( I removed it's original soft covering ,,,,don't enjoy rounded over corners and edges etc. ). It has a very clever and convenient sandpaper clamping system.
I don't often use the ' Robo ' system , but the drum sander gets a good work out. The drum can be lowered into a hole in the bench top when the Myrtle plate is removed.

This is a pic. of my Saftey Planer set up. I find I don't use all that much either , but is handy for reducing down the back of headstocks , thicknessing bridge blanks ,headplates etc . .I thinned down those Tas. Myrtle slats to give just the right amount of hold down flex , although the bearings are adjustable foe height anyways . They can be turned to suit your direction of cut also .

I made this quite some time ago and is my favorite so far . I've posted pictures of it before , so apologies to those who are probably sick of seeing it !
Made from scrap Aluminium ( Aussie spelling

), Brass , Bronze, Copper and Steel. It's in metric . The needle bearing spindle is from a record player turntable . The upper bout of the little guitar becomes the cam , while the lower bout acts as a counterweight . There is also a counter/counter weight on the indicator arm. The lower anvil ( below the measuring probe ) is radiused at it's base and sits in a bronze bushed hole and can move around quite freely This radius is of the same radial tangent as the probe's tip giving a consistant reading no matter what angle the wood is presented to the jig , whereas A conventional rounded domed anvil can give a higher reading unless presented at the exact 90 degree angle to the probe
