Confession, I am an OCD tool whore who believes that the guy who dies with the most tools wins. I have and have used alternatives to Shopsmith, but I really like the platform. I own 5. 2 510's that I use regularly and 2 more plus a greenie that I'm converting to dedicated shorties. Looking for another as wall mounted drill press. Yes, I have a metal working floor drill press too.
So, after scouring posts everywhere, and talking to Incra, the Incra customized fence was discontinued due to insufficient volume. I didn't like that it didn't lock down on the ends.
So here's what I'm pondering. Why couldn't the Shopsmith rail system be mounted in tandem with the Incra? And the Incra is only real sensitive about left right alignment, it doesn't ride the rails or rely on them except to lock. Cut the rails in chunks per table. Then you preserve table system expansion/flexibility and can remove the Incra easily to default to the Shopsmith fence for those setups Incra can't do. If you need to lengthen the Shopsmith fence, hit Grainger for a piece of t track framing extrusion and thread a rod for a longer rear lock rod. There are stock extrusions the right size with t tracks to sub for either 510 or 520 fence. I'm going to experiment when the desert weather cools.
Trying to think modular like Shopsmith designs. Thoughts? Suggestions.
