Title: Workbench "Floating" Design Help
Post by: Jmacpherson on September 04, 2018, 02:39 PM
Hi all

My current small home "shop" is getting cramped and I'm thinking of moving to the back of the garage.
I mentioned on a previous post once before that our garage is below street level and that the driveway angles down steeply.
I won't go into all the details but to say the floor of the garage is designed and shaped to allow any water to drain towards the garage door and the drains outside it. There is a channel along the back of the floor and sides which also angle down and to the front.
There is some moisture in winter and the floor can get damp in the channels - the original renovators hit the water table (long story)

I've added a rough sketch drawn in paint - no I'm not going to get any awards for it but it should portray the floor/channels and work bench idea

To overcome the floor which isn't flat and potentially damp I'm thinking of "floating"work benches along the back wall and a portion of the side walls.

I would use a horizontal ledger bolted to wall (masonry wall), pressure treated would be best but not always straight. Would painted pine work just as well?
Then have perpendicular supports attached to the rear ledger using either toe nail screwing or pocket holes.
Then have a front ledger to keep it all together.
Then under each horizontal support piece have an angle support going back to the wall

The last part I'm not sure if using brackets and mounting to the wall will be strong enough or if vertical supports should be attached to the wall and then screw the angle supports to that?

Will my design/idea be strong enough etc?

You could still use front legs and just use screw adjustable rubber feet to compensate for an uneven floor.  That would give you the strongest bench.  No need to go with treated unless you are coming into contact with moisture.

+1 on neilc's reply. Also, when you have front legs, you can also have shelves or cabinets below.

Use front legs, epoxy the bottom end grain and up about 2-3", damp cellar will not affect the legs then.

You have gotten great advice.  If you incorporate the angled brace pieces go with pocket screws.  I did something a couple of years ago and loved seeing the pocket screws cinching everything up tight.

Thanks everyone

I didn't even think of adjustable feet.
I was struggling with shelving under with the floating bench and figured square boxes on the wall above would be my only option.

My plan was to use my Kapex on the ug cart (i don't have the wings) and level it at the back wall with the carts feet.
Then use the top of the saw plate as the reference height line for the top of all the bench surfaces right round and then work my way down
