I don’t have a shop, i have a shed and a carport into and out of which i roll my tools when i work. I’m going to be receiving two 12’ long walnut slabs soon (about 10/4) and I’d like to level them with a router sled. I’m not really sure how to do this on such long pieces. I’m most likely going to cut the slabs down to 8’ as that’s the full length i will need (bar top), but i don’t have a workbench to rest them on while i level them. I haven’t measured it, but if the concrete slab that is the carport floor is one piece, should it be level enough to work on? Also, I’m wondering what I should use for the runners upon which the sled will ride.

-I was thinking of angle irons, but I can’t find an angle iron that’s long enough and wide enough (was looking for 3”x96”).

-Maybe 4×4s? I have a 6” jointer with a bed about 4’ long and a 13” benchtop planer. Would i be able to get true sides with such a long piece of lumber?

-I had a brief notion of building a sled with casters to forgo the need for runners, but i don’t imagine i can get the carport floor clean enough that the casters won’t be rolling over little bits of debris and screwing up the level.

I’m mainly commenting to see other people’s input since I’m kind of in the same situation. Of course I have a shop, but only have one table and it’s my outfeed table and not big enough for a couple slabs I have. Thought about getting a 4×8 3/4” piece of plywood. then true up some 2×4’s and build a big box to lay the plywood in, then add rails for the sled perhaps. My next project is going to be a live edge coffee table, luckily it’s only 4×3 but still going to be a challenge since I’ve never done it before. Of course the main thing holding me back is trying to figure out what I want to do about legs, go with pre made steel ones or try and make my own base from wood.

If you make something like this using 1”-2” pipe with cross sections attached via T-connectors, then you can lay the slab right on top of the rails for leveling. The four corners can be long enough to serve as corner legs.

My suggestion is to spend the time and money to build a assembly table,it can even start out on saw horses.Make it wider than your slabs.Then build a contraption that will hold a router to slide across and down the lenght of the slab.
Use winding sticks to make your assembly table flat and free from twist.
Don’t be surprised if it takes several days to make the whole thing your first time.And a half a day to machine the slab flat.
Many videos on router rails.Theres really no short cuts.

Have your say...
