« Part 8: Fitting the Lazy Larry Bearing Part 9 of Circle cutting series Part 10: Arc cutting like Patron does. »

With the big clean up and purchase of new equipment, I decided that the old ratty jigs had to go… and I have now built both a cutting jig and a sanding jig…
Started with some Melamine… and then cut a dado in some Camphor for the sides… this will also help support the material…

The lower part of the sides wraps around the table on the Bandsaw… and on the Disc Sander… using t-nuts and star knobs I attached cleats under the table to hold it in place…

The material to be cut and sanded it placed on a bolt inserted into a sliding dovetail… another t-nut and star knob are use to hold the sliding centre in place [from underneath].
Turning the star knob pushes the centre up against the two side capturing pieces…

The material is then turned on the bolt… very quick, very simple…

This jig can accommodate circles up to 800 mm… or 32 inches… in diameter..
The sanding jig uses the same principle…

I noticed on the original sanding jig that the circle was sanded on one part of the sandpaper only… so I made the centre slider wider to enable me to insert to bolt at alternative positions to use all the paper…
Next on the list, a Patron Jig and a Curve Cutting Jig..
Any questions or comments… feel free…

Let’s face it, those are production jigs, and you have to make them much more robust than a jig I might make for the same purpose. Even storage would be a problem for me. That said, they tell us amateurs what it takes to make a robust jig that will stand up to abuse. I have a circle cutting jig for my bandsaw, and it does work, however I don’t think it would take much abuse. So thanks for setting the high bar, sometimes the construction of something more robust or flexible influences the plebian jigs we amateurs make.

Very resourceful and you made life easy. The sliding dovetail you constructed is angled at 45 degree. It is same as lathe (machining lathe) compound rest. That is a nice idea that I can copy for my incoming manual thicknesser using portable planer. Thanks for the idea.

Great looking jigs but more important very useful jigs. You should get a lot of work out of these bad boys.

Hi Larry.

Here’s an idea: cut a slot for the bolt that acts as the center so it can be moved side to side, allowing the use of the entire sanding disk with less trouble changing than the idea you mentioned.

Why is it the more intelligent a wood worker is, the simpler his jigs are? :)
