I am to Join multiple board together to form a 2.625 x 2.625 block of wood.

I cut the width of all my boards to 3" or over 3+"

When I check the thickness I am right on 2.625 or just over or just under.

These are for the top and bottom rails and legs for a new work bench.

When I run the glued up assembly they the jointer again.  I will be undersized for my T.

What is the minimum board I can perp to be added to the T thickness on a planan safely.?

Also because the cut line will be very close to the glue line should I bother?

If i gule on a 1/4" board to the ohter already glued boards I will be nearly 3" thick which will get cut back down to 2.625.

Can I safel TP solid oak board down to 1/4" or should I add a carrying table?

Then how do you go about clamping this thin board.  This wood has holes throught by bugs but they do not cause any trouble stucturally just for glue up the glue squeezes thru the holes.

So it is one board at a time.

 

My lunch box planer (Dewalt 735) will safely plane to 1/4" without a carrier. Just have to make sure there are no lose knots or exceptional wild grain.

why not just buy some 4x4 stock?

Like Lew said Michael, and keep in mind your boards are not wide, if you were planing boards in the 8 inch plus wide range, I may consider a sled, but your narrow boards will glide through.

If you end up with a board 2.625" by a hair under why is that a crisis?  Just adjust the length/width/thickness of the adjoining boards to compensate. If it is a frame member no one will notice if it isn't a perfectly square board. 

 

I've dealt with designs that due to wanting to be some perfect dimension that doesn't divide evenly by the thickness of available stock and as such cost another 25% and more waste because another board would make it too thick and need to be planed down.  Never encountered a case where using a thinner piece led to critically compromised structure.

For a work bench, normal dimensional lumber should suffice. 2x4, 4x4….

When I want to plane below 1/4" thickness, I use a ~ 30" long x 12" wide melamine board which has a cleat.  I also cut a few extra pieces, because some times the planner does not play nice with the board.  I have planed down to 0.100 with littler issue.  

 

Suggest gluing the narrow board to the middle of the three piece sandwich before planning to final thickness.  this method will eliminate clamping issues and the issue of having the glue line close to one surface.

 

As suggested, adjusting leg thickness to something other than 2-5/8" will never be known unless you mention it and should not impact the build.

Thanka all,

1. why hot buy 4x4 because a have a lot of this oak to use up.

2. My TP safely cuts 1/4" with no problem well as is turns out my Jet 15" TP does also.

3. I decided to resaw some boars and get them glued on the other side of the Oak in the middle.

The Oak in the middle is quarter sawn and the two laminations are plain sawn.  So the glued assembly should be stable.

I and now on my way to 2.625 Thick ness for the required components. 

4. If you are close then just use it as it is well after cleaning up the jointed board I was only 2.375 T.  So I joined another .375 and now i am ay 2.75.
