I think I might get one tomorrow. Dammit.
Might as well drag this completely OT now... I have my old TDO6H 20g back, its going on the 91 tomorrow. PRoblem is the WG flapper and arm were removed for use with an O2 mounted setup. Like the 2g, the 1g is using a manifold mounted setup (venting all 4 runners as well). Rather than weld to the housing, I typically just make a new "gasket" and dont cut out the hole for the WG passage.
The last one was relatively thin mild steel, and it started to warp at the WG passage after many thousands of hard and hot miles. And that was an absolute bitch to fab up, I cant imagine how much of a pain in the ass thicker material will be. Hole saws just dont get through before they eat shit, and a grinder is so slow and sloppy. Some pnuematic nibblers might be worth looking into. Anyone ever try the Fisher Price "My First Cutting Torch" mapa and oxy cylinder setup? It was relatively cheap at Lowes IIRC, and for the limited use it will get over the next year or so may may it worthwhile. A full blown torch setup would be nice but after making this piddly little block off plate it will collect dust for the next year while I waste my life trying to build a house. Hardly worth the expense.
