Auxiliary Top

[Kevin12]

There are lots of ways to cut circles - bandsaw, scrollsaw, router (as mentioned) - I've even seen jigs to cut circles with a table saw. Seems like it would be a question of size. I once needed to cut circles about 1 in in diameter - that called for scrollsaw, of course, but I didn't have a jig. Did it freehand with a "pattern" - came out ok enough.

I like the idea of auxilary tops - jigs, close to 0-clearance, etc. I also like the idea for extending the size of the table. I've done some door-toppers and other lengthy (pun intended) things and a bigger table would have been great. For me, though, my saw is SO OLD the metal insert fits less than perfectly in the metal table and no matter how I file and diddle and futz and file some more, I'm always left with a burr or edge that will scratch the bottom of my wood. Ergo, an alternate table top.

I've thought of all kinds of materials for an alternate table top -- thin ply, thick ply, melamine, UHMW PE (ultra-high molecular weight polyethylene) - all kinds of stuff. But it never dawned on me to use "tabs" to hold it on the table !!! Now I'm thinkin' not just tabs but tabs that will wrap around and grip the table -- thinking counter-sinking and thumbscrews and ...(How can I feel so tickled and so stupid at the same time!?!)

Thanks a ton!
