Edge Jointing Question

Edge Jointing Question

Angelo in Cornwall, NY

>Suppose you work in a school that is renovating all of the science labs. Suppose there is a bench with a 2" thick maple top, 4'x8'. Suppose the principal tells you that you can have it, but it has to be gone today. Suppose the only way to get it home would mean ripping it in half (gasp!) lengthwise. Suppose you borros a circular saw and do just that, without a strait edge.

How do you suppose someone who just did all that would go about jointing the cut edge on a 200lb + hunk of maple? Looking for any and all suggestions. Clamping it in a vise is not an option as the edge would be about 5 feet off the ground. I'm thinking of clamping it flat to the bench and laying the jointer on its side.

>Jonathan, Didn't even think of that! I guess with the weight of these things, they won't move. BTW, Where abouts in NY are you?

>Hi Angelo,

Put supports into the legs of the bench, say 1-1/2 feet off the ground; angle these supports slightly upward; set the maple beam on them and have at it. It won't go anywhere.

Supports could be 1/2" by 5-1/2" lag bolts or so. Or something fancy like triangular brackets that could be fixed to the legs by screws

Two cents. Wiley

>Color me stupid, but why not just match the saw-cut edges back up. Then you wouldn't have a problem with jointing the edges. ??

>From your tone, I am guessing that this all a theoretical exercise, right? Nah, I didn't think so. :)

I like Jonathon's idea. I have done this before while planing the edge of a door. Since the door was so light, I had to put it up against a low immovable object (front bumper of a VW).

I'm not sure about the idea of simply butting them back together and gluing. I'm not an expert (or even close) but I don't think you would get a very good bond on two rough surfaces as left by a circular saw.

My 2.5 cents,

>If a fella had a table saw with a glue line rip blade in it it sure would be easier to start with a nice straight edge. Then a little planing to make the fit perfect.

>Table saw with a good blade (assuming that your original cut was roughly parallel to the long edge) will give a glueable edge and not lose much in the overall width. You will need good outfeed suport for 8' by 2' thick maple though.

>Angelo,

I think 4 feet is too wide for bench. It would have to be a stand alone for you to reach the other side. I think my bench is only 22 inches wide. Why not use the second section to build a base for the top. Maybe you could also use it to add wide skirts to the top like the Nicholson bench. This would add a little width also.

>Mike, the edge is way too ragged to even think about regluing as is. Wish I could tho.

Thanks all

>I think a couple of stands would be the best option. And as it turns out, my former department chair is going to take 1/2 for her new workbench. At this point, I'll just be cleaning up the edge of our new bench tops.

>Best concept I ever saw for those used thin plywood across the bottom, and short feet on each end of the ply. As the door or panel rested on the ply, it sagged, thus turning the support into a clamp. The heavier the door, the greater the clamping force.

You Have Two Benchtops

Todd Stock

>You might consider financing the rest of the lumber and hardware needed for a bench by selling one of the two bench top blanks.

After adding a tool tray and bench dog strip, the bench width will be in the 32-36", which is a nice size. You might even find someone here on WC that will give you a quick lesson on how to handle the chore of squaring the edge in exchange for a reasonable price on the remaining half.
