For a job in Northern Vermont, for a maple syrup co-op, I had to make some gas spuds for the (2) 750 hp boilers that will run on propane, or about 33 million BTUs. The spuds are a form of gas jets, there are 20 of the spuds in each boiler and I had to replace 1/2 of them in one boiler and all of them in the other, for a total of 30, in this configuration. So I took some pictures of the work in the shop, so here we go.
1 - the starting point, 30 nipples, bushings and plugs all 304 stainless steel
2 - cut the spuds to length, with a carbide tipped parting tool, on the lathe
3 - another view
