If you follow me on Instagram you would have seen that I am currently making a live edge dinning table. I have filled all the voids with epoxy and now I need a way to flatten that top. In this video I am going to show you how I built a router flattening jig.

Wes, thanks for the info. I used your plan and made a jig to flatten a 10.5 ft by 22", 2" thick live edge walnut top for a sofa table. All of the parts came from left over pieces of plywood and melamine. Since I am much older than you at 83, I put the jig up on three 18" tall wooden saw horses that I bought from Home Depot many years ago. As you suggested, the entire jig was carefully shimmed and leveled. This gave me a higher platform to more easily flatten the piece and not so hard on the back. Flattening was a bit of challenge in that the piece had a pretty good twist in it. Shimming and looking at it from many angles. After partial flattening on both sides, I had to raise the piece and used one then two 1/4" by 1 1/4" tempered hardwood pieces about 20" long lying on top of the 4'x8" pieces. This worked very well and kept the system in tact and level. I did wax the sliding rails with Johnsons paste wax and this made the sled slide easily. I am very pleased by the way this worked out and the walnut top looks great!. Thank you. Bill

Nice, but I used an old bed frame I found by the dumpster. Plywood is too crazy exspensive for that. It also has screw adjustible feet and collapses into 6"x 6" rack I made for my router like yours. Hope this helps someone reading this for their project. I've used mine to make dining table tops from old pallet wood for several customers.

I enjoyed this video simply because most router sled videos only talk about the router sled, not making the flat reference surface to hold the slab. What's making my head hurt though, is that you level the cross pieces and call it good, when you really need to know if the cross pieces are all in the same plane as each other and that the rails are the same height above them and are orthogonal to the cross pieces. If one of your rails is slightly lower than the other, then your flattened slab would have a slight wedge shape to it, right? I guess if you flip it the right way and flatten the other side, that problem would be taken care of but the sides would be slightly angled.

@zackmack4712 2 жыл бұрын

Thanks for the inspiration. I've built an outdoor table out of oak and it's got a bow in the table top after I squeezed it too tight in the glue up and without enough horizontal supports. Anyway, I'm gonna give this method a go but I figured I'd attach my sled rails to the table legs since it is already assembled. Hopefully that method works well

Fantastic solution to a problem I’ve been pondering. I’m going to be getting a large burly oak cookie at some point and want to make a table out of it but hadn’t figured out a good way to flatten it as my workshop is half of a two car garage. This will do this trick. Since you have that crane thing though, you should definitely use it to suspend yourself while flattening your slabs because I’m guessing doing the flattening on the ground like that is going to wreck your back.

Thanks for this video!. I did build one exactly per your instructions, however, you actually run out of plywood after you complete the rails. The three base supports take up half a sheet of plywood and the six 3" x 8' rail parts take up the other half. There's nothing left to make those funky Y-shaped dilly bobbers. Are you sure you didn't use lumber that you had laying around?

@bullfrogpondshop3179 2 жыл бұрын

Getting ready to flatten a couple tree cookies. I inserted the router bit (Whiteside 6220) all the way into the router collet. When the router is plunged all the way down, the bit only protrudes about 3/8" below my sled. This is with a very thin base plate (~1/16") and a sled made from angle iron (~1/8"). How are all these guys getting any bit depth with sleds built from 3/4 ply? My bit wouldn't even clear 3/4 ply. Is it ok to insert the router bit NOT all the way into the collet? I'm concerned it may wander upward or downward while cutting.

I built this exact sled based off everything you said and the only problem I ran into was after I placed my slab on it and placed the sled across it, it’s touching the bottom of the sled the entire length. So I think my slab is thicker than yours and that’s the problem. Do you have an idea on what I could do to raise my sled up? My only idea is cut a piece of 3/4” plywood 1 1/2” wide the entire length of my rails. That would raise the sled 3/4” taller. What do you think?

@contessa.adella 2 жыл бұрын

In theory..as wide as you like, but remember the wider the router carriage, the stiffer it must be to ensure it does not bow under the weight of the machine on it. Also, there is a practical maximum you can reach across and you might need to devise some clever (and safe) way to slide the router if you can’t reach it!

Those should bring it up to a more comfortable height while being easy to disassemble for storage. Suggestions are requested and welcome.
