All Replies on Using a Craftsman 113 top as a wing for a 315 saw?

It could work, but the holes may not line up. That’s not a huge issue, however, since cast iron is quite easy to drill holes in. Just drill some new holes and bolt it on.

You’d be better off if you have a pretty beefy fence/rail combination, since the angle steel from the fence rails will help hold everything together. If you have the OEM fence, you might end up with a lot of sag.

That should work. I have purchased a few extension wings off of ebay, you just have to get lucky and find solid ones that don’t cost a fortune. I got lucky once and scored two wings for about $30 and then $50 for shipping.
More recently I put an ebay Craftsman wing on the right side of my Grizzly and it bolted right up, no drilling. (I have the G0651 and I substituted part of the MDF right extension for cast iron)

-- Two thumbs and counting

Have you thought about installing a cast iron wing with a router table cut out like the benchdog or MLCS? It’s a pricey upgrade, but a good one if you have limited space. I was lucky with my 315 saw it had a solid cast iron wing on one side with a router mount and a stamped wing on the other that I replaced with the Benchdog, I now have 2 routers mounted on my saw. I’ve also seen where people filled in the webs of the standard CI wing with wood.
