Details from J&S tub
It's 6' diameter
About 4' tall
4 steel bands
Serviced by 240V, two 50A circuits.
pump is 120V, 13A, US motors R55CXFCM-0305
heater is ACC applied computer controls SMTD-3000-0D-GAS-8.KW
UV filter is Paramount Ultra ultimate UV water sanitizer
wood thickness of staves/sides is 1.5“
staves/side pieces are ~5” wide.
They have a pump, a heater, a physical filter, and a UV filter.
Details I need to clear with Aline
How tall? 4'
What Diameter? 6'
Are we heating with electricity(have to run it out there) or fire(burn bans) or propane(expensive heater and ongoing cost)? Aline would like to go electric. Investigating if our panel will support that.
What's our budget? $5000
Are we putting chemicals in the water or no? T would rather not
Are we putting salts in the water or no? T would rather not.
Can Tony build a solar power sand filter to just clean the damn thing all day? total budget about $100
Do we want a stainless steel band or a covered metal “rope”?
Math
What is the volume of the tub?
Volume = area * height = pi*r^2 * h = 3.14*3'*3'*4' = 113.09 cubic ft
How many gallons is that?
Approximately 846 gallons, per google
what is area of bottom?
area = pi*r^2 = 3.14 * 3 * 3 = 28 square feet
Approx how many linear ft of boards will that take?
Our boards are appox 11“ wide, let's assume 12” for easy math, this is an approximation. Also, we need to be slightly smaller than 6' wide anyway.
So we need about 28 lf of boards. It will be more than that, we're going to lose some to tongue and groove.
Approx how many staves will we need?
circumference = 2*pi*r = 2*3.14*36in = 226in
assuming 5“ staves, we'll need 226in/5in = 45 staves
Assumptions
Math Notes
Videos And Articles / Resources
We need a Bead and Cove router bit set, 1.5”, with a 1/2“ radius.
We might need a beefy router for that. 1/2” shank capability.
Gonna need to cut a good Dado joint to connect the staves/sides to the bottom.
The Rough Plan
Find a spot
Make a foundation
build a base using tongue and groove
make side pieces using bead/cove bits and dado them to fit onto the bottom
Put on the staves/sides
