Hello John. I am Making a small hot tub in my backyard, 4 x 4 foot. I'm putting 7 jets, do I need to put separate pump for jet and filters, and how do I buy 7 complete jets with housing like the one you have?
@@ShahriarBahmani-z2s get a hold of Gene at custombuiltspas.com and he can run the specs, see how many jets you need, calculate the HP of the pump you need, etc.
Hi John. I noticed you mortared the block straight into the concrete base. I was told I need to have steel rods/bars coming out of the base. The blocks are then to installed over the steel then the blocks loaded with concrete. Is this necessary?
Not necessary unless you plan on building a deeper tub than mine. And mine is deep. That’s a common way of building pools. But not necessary for this type of tub. (Please look into Gene’s book at custombuiltspas.com for a more detailed explanation.)
I’m a math guy. The Pythagorean Theorem is definitely useful. BUT way more practical to find, or make, a 3 and 4 to measure your 5. For those who don’t walk around with a scientific calculator and get overwhelmed by decimal and fraction conversions, I’d say sticking with the 3-4-5 method (which is really just a simplified Pythagorean equation anyway) is the most practical solution. In my opinion of course. :)
@@johncoaltrain9485 Haha yeah I don't bother testing my mental math abilities. Larger scale it is more practical to go 3-4-5. Though i'd argue that everyone has a phone in their pocket now days 😂 I'm thinking from a metal fab point of view, often I have needed the theorem in situations I didn't have the length on a or b and a square isn't comfortably usable. Up to part 6 in this build 👌
@@friendlyoldbum9182 I’ve spent my life learning how to calculate in Freedom Units, so I can’t be much help with metric. 😂 I kid, I kid. Good luck on your build if you’re trying your hand at this.
I’m doing the same project too. Great job 👍

@@johncoaltrain9485 Thxs...appreciate it
If you use Pythagoras Theorem correctly you can use the total length of your edges (a and b). You don't always have a easy 3-4

@@johncoaltrain9485 I'm in Aus so we use metric, imperial would be a pain in the butt.

You remember what the cinders cost, roughly?
I don’t, honestly. Construction material costs fluctuate a lot these days.
