Build looks awesome. I'm closing in on finishing my single tier...I think yours has the edge.
I think I'm going to try using the 1/2" pipe going into my Honeywell valve to support it since I didn't build mounting brackets. Hopefully it'll be strong enough.
Thanks Brian! Looking forward to seeing your build thread.
To mount the pilot burners, I first straightened the L-brackets attached to them. I then fed the pilot and thermocouple protrusions up through one of the triangle-sized holes in the banjo. I marked the two bracket holes on the burner underside with a sharpie and drilled them out for two screws (note to self, replace with stainless steel). I did put rectorseal on the screws before installing them just to prevent gas leakage there. Here's a picture:
I was initially going to do the same thing, black pipe to support my valves. I wanted everything from the valve up to the burner to be rigid, and everything from the valve down to the manifold to be soft. That way the valves move with the burner height adjustment and the pilot/thermocouple lines are not being bent repeatedly. However, I quickly realized that there is no "official" way to go from black pipe NPT to the 3/8" flared orifice fitting with rigid fittings (some on this forum have done workarounds, like brazing the two together, etc but I didn't feel great about doing that). Anyway, the options for me were copper tubing union, or a flexible hose, neither of which would give me the rigid support I wanted. Thus were born, the brackets.
In case you need any, this is a good place for those flex hoses in all sorts of sizes:
The brackets mount to the bolt pattern that is already on the valve. Coming out the top of the valve is a brass 1/2" NPT to 3/8" flare elbow. Attaching that to the burner orifice is a 12" x 3/8" flare to 3/8" flare flex hose from PlumbingSupply.
Below the valve is the standard yellow flex hose from Lowe's that comes with a 1/2" NPT to 1/2" flare adapter.
