Default Propane, Single tier, direct fired RIMS build

I know there are many like it, but this one is mine.

2" mild steel stand with locking casters based on n2fooz design, here is his awesome thread:
http://www.homebrewtalk.com/f51/my-single-tier-build-289260/

High temperature engine primer and paint (painted outside at 40F = bad idea)

3x BG-14 high pressure burners from Bayou

6"x24" 16 gauge heat shield

Camlocks, silicone hose, weldless bulkhead, 2-piece stainless ball valves, sightglasses with thermometers all from Bobby M here,

Including his new, hot, full keggle diameter false bottom here

Chugger pump with stainless head

18" Flexible propane hoses from Kurt (onehoppyguy) at Brewsteel

The guys at Visilift for their welding assistance and allowing me to use the shop.

And countless other threads on here, thanks a bunch for being so damn helpful.

And now some beer pron

Nice build. Where's your RIMS tube?

No RIMS tube. The mash is recirculated with the pump while low heat is applied from the burner underneath.

Have you noticed issues with hot exhaust gas not being able to vent because of the kegs skirt on steel the whole way around? I sketched up a similar top, but I think I'm going to get rid of the 45° corner pieces to allow better venting.

Also, got any pics of the casters and mounts for them?

You might be able to notice on one of the pictures that the heat shield does not wrap the full circumference of the burner. That provides a little venting, and so far, I have not had any issues. I mounted the heat shield to those 45 deg corner pieces, so I needed them there.

Many other stands have little raised bits for the kegs, which I may still add, but so far so good.

I welded a 2"x2" square bit of steel into the bottom corner and drilled a 1/4" hole through it. The caster has a 3" bolt that goes through the hole, with a nut on the bottom and another on the top for leveling. I will post a picture of the mount this afternoon.

Yep I've seen that. I drilled holes into the keg skirt to guard against it. But the reason I do not use a full circumference heat shield is for venting gas. The other option is to attach small risers or spacers to the frame to lift the keg and create a space.

Ok, I take it back, I do need spacers. I thought the holes in the skirt were sufficient but testing last night revealed a huge difference in flame intensity with the keg lifted 1/2" off the stand, in addition to the skirt vents.
