I was going to use Z brackets to attach the vertical 2x4 to the 2x10s and 2x8s, I was told they cost $0.25 each But when I got to the hardware store they were $1.60 each. Well.... I needed 44 of them
So, I decided to redesign the walls of the frame.
This is what I have built, The studs are 11-1/2" on center with a removable stud to access the pump/heater. http://img.photobucket.com/albums/v738/ARTHUR101/222.jpg?t=1180682983
The bottom of the hot-tub(foot well) that sits on the frame is only about 2'x3' and it is NOT level, There is about a 1-1/2" gap in-between the foot well and the frame on one side. (Yes it's the hot-tub, Not the frame
Originally the hot-tub was sitting on drywall compound/Spackle.
It's going to be outside, So I want to use something water proof to fill the gap. After seeing the post about concrete, I think that's what I want to use.
I don't want to add another 200 pounds to the frame, So I want to make some light-weight concrete by using perlite in the mix.
I have never worked with concrete before, So I have some questions.
What kind of concrete should I buy? (preferably from Homedepot)
How much perlite should I mix in? I want it as lightweight as possible (keep in mind the hot-tub was sitting on drywall compound)
Should I pour the concrete directly onto the plywood or should I use a plastic sheet in-between the concrete and plywood? (I will be using a plastic sheet in-between the hot-tub and concrete)
How long will it take for the concrete to harden enough before we can use the hot-tub?
I'll post some pictures tomorrow.
