Topic tags/keywords: counter top live edge support

Constructing a 30”(+/-) wide, 2” thick live edge counter top for the wood shop located in 1/2 of a 2 car garage.
The top will be a glue-up of several boards of Maple.
Rear edge of the top will be continuously supported along the wall.
The front edge will be supported by pipe legs at various locations.
This will leave open spans for mobile cabinets, table saw, work bench, etc. to be stored under when not in use.
The longest span will be 7 feet.
Looking for options to reinforce the front to prevent sag and make the top more ridged without increasing the thickness.
Considering using “C” channel cut-in the underside of the top running about 6” from and parallel to the front edge. Cross supports will also be cut in at the pipe legs.
Looking for a size recommendation of the “C” channel.
Will consider other options like angle iron, or T bar as “C” channel maybe over kill and cutting in will reduce the strength of the front edge.

No matter what you do the elements will play a big factor.. i wouldn’t glue that unless it was 2,3 or 4” max on boards… Now I have a 2” thick hickory top that’s 30+ 60 that’s bolted down and has no problem, but the garage is acclimated all year around without car traffic and its a two car garage….

We used square channel on restaurant tables and it will help some. The angle iron is the best bet, but needs to be drilled with a slot to expand and contract…

2” inch thick maple with a continuous back wall cleat? Heck I don’t know why you’d need any re-enforcement on a 7’ span. And why the live edge for a work bench?

i agree jack but this isn’t a 3×3 snack table,he’s supporting across the back and each end of the 7’ span,and it’s 2” thick maple,i just dont think it would be a problem really,but i may might be wrong.ymmv!

Is there any particular reason you can’t use one more support to break up the 7’?

According to the sagulator, a 30” wide 2” thick thick sugar maple top with 84” span will sag .08” ( a little more than 1/16”) even with a 1000 pounds center load on it and with it supported along the back as well, probably a negligible amount. I think that you are good to go but if you can put at least 1 post support somewhere in the middle to cut the span, even better.

When sourcing wood for the counter top found 4 reasonably priced live edge Red Maple slabs. Average wide 22” at 14’+ long. Since the garage is a multi-uses space and I’ve never done a live edge piece; wanted to try. Recently completed covering 2 garage walls with barn wood. The L shaped counter top will be against the barn wood with each leg about 13’ long. When the space is not being used for woodworking, the mobile table saw (6’ long) and mobile workbench (6.5’) will be stored under the counter top which dictates the max distance between the pipe legs @ 7’.

Thanks for all the input and the link to the sagulator.
