+===== 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?
+  * How tall? 4'
-  * What Diameter?
+  * 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)?
+  * 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 ====
-  * 5' across
+  * 6' across
   * 4' tall
