I’m sure most of you have seen jigs for flattening with a router. It always involves a sled resting on rails that are set perfectly parallel with each other. It’s a great idea and it works but it takes a long time to flatten a large surface. Has anyone ever seen a jig based on the same idea but uses a belt sander instead? If you don’t need to remove much material this could be much faster. Sound feasible?

If you don’t need to remove much material, a hand plane would be faster still.

But the idea does sound feasible. You’d have to take care to make sure the sander’s platen was leveled.

The very best process for accomplishing what you want to is to take your project to a cabinet shop and have them run it through their 24” belt sander a few times. You will spend more time and money on gas to get to the shop then you will paying the guy a few bucks and waiting ten minutes while he does it.

Thanks. This top is 42” wide and 78” long. I got the boards all within 1/32” of flush with each other, even closer in most spots. A huge belt sander would do a great job. I am looking into hand planes. I sure wish I had a try plane, but haven’t spotted the right deal on one.

Yeah, a router contraption like the one you were discussing does work fine, but it takes time, I have done a few 20-30” wide slabs like that, but in order to save you some headache for this case you should deifnitely go with a regular handplane.

A router jig is more useful where you have big differences like 1/4 or so, in which case you still need the handplane to take of the bulk of the material, but for a 1/32 or less of a difference just get yourself a no7 or something of the sort and at 78” it should not take you more than half an hour to get flat.
