c-channel for table top?

[trook]

I remember seeing a table a while back that used c-channel instead of plate for a top. It seemed that the OP stated that 6" wide channel with approximately 2-4 inch gaps between each piece made the table much easier to use clamps, etc. It seemed like the cost and weight were less too. Any thoughts?

I agree, I like a nice flat surface. Also, the back side of C Channel tends to be pretty concave, and the gaps inbetween I think would get in the way more often the they would help with clamping.

I like the idea of the gaps, but I'd rather it use 1 inch plate, 8 or so inches wide, as opposed to the channel. The channel is going to be near impossible to clamp to, without making a clamp that bridges two channels. The plate will allow clamps in the gaps, as well as being thick enough to drill and tap holes for various thread in accessories, or just drill holes for hammer in bench dogs.

Having the table bolted together might be nice for moving. Unbolt it and break it down into parts that are more easily carried. On the downside a bolted table may not be as solid. Bolts with tapered alignment pins would be nice, but way more work.

A table with c-channel or plates might have another advantage. You can remove some of the pieces in the middle of the table. This might be nice if you have some odd shaped blob or stuff sticking out of the middle of your workpiece.
