DIY Kalk Reactor

[sleeman]

Well I got bored at work the other day, so went to the shop and made this up. It is 24" high with 4" extruded. The base and flange are 1/2". Why did I use 1/2" you might ask? Because it was free. I used weldon 16, but I think I will use 40 for the next one. The open union on top is for pouring kalk mix into and the flange is held together with 6-3/8 inch nylon bolts.
It was pressure tested last night, and has been dosing since about 2pm today. For those interested, an MJ 400 CAN NOT withstand 30 PSI. I blew the motor off the other part and threw water across the office.
I don't know that I would use 1/2 for the flange again, as it was very hard on the router. I actually put a nick in this flange about a 1/4" while try to clean up the edges. I had already tapped all the holes by this point and didn't feel like making another flange.
Cheers,

Al
