Have you ever needed to plane some boards very thin,

like less than 1/8 inch thick, With this jig you can do it.

I have a 735 DeWalt and you can not get them that thin.

So I built this jig, I started with a piece of 3/4 thick

Marine plywood, and cut it 13 inches wide and long enough to

fit all the way through the planner, then I glued a piece of laminate to allow the

wood to slide easy and a French cleat

to hold it in place while it is on the planner ,the cleat also allows

me to hang the board on the wall behind my planner.

The jig works great and who knows some day I might want to make some popsicle sticks

That is a cool idea. I make thin boards by putting them on a real flat piece of plywood with rail in the front so the wood pushes against it and I feed the whole thing through the planer. I have never tried to make a table like that.

Thanks for posting!!

Cheers, Jim

Yep, I have one like that too. It works great.
There’s also a narrower version for being able to mill 12” wide boards with an 8” jointer.

Sometimes it’s good to get creative.

Interesting. Yes I have just used a 1/2 Plywood under the thin boards many times.

If the laminated board extends past the outfeed table by a foot, or so, snipe is almost totally eliminated.
Pre laminated shelving material from the BORG works well, too.

Has it not occurred to anyone that Dewalt may have limited how thin the material is that can be planed for a reason? This is not a new strategy. I tried it 15 years ago. At some point, the whole work piece will get caught up in the cutter head and just get shredded. Don’t say you weren’t warned.

Yes, I have used double sided tape to stick very thin stock on both the planer, and the wide belt sander onto a “carrier board” it works flawlessly because it is gripped by the rollers, and there is no slipping as it feeds through. A friend of mine built one like this on a slick laminated surface and he reported way to much slipping, and inconsistent flow of the stock through the machine because of start and stop slipping. He called to ask where I buy my double sided tape.

Both he and I have 15” 3 HP planers though, maybe it would work on the 735, but I don’t know what would really be different?

You can also use the painters tape and CA glue method that appears to be extremely good for not only thin material but also heavy thick material.

Here is a video on a CNC.
And this video in a pro shop

It’s amazing how well it holds and is easy to remove!
