A while back I made a set of gas spuds for 2 large boilers, I was told they needed to be 3/8" x 4-1/2" stainless steel gas spuds with (10) 3/16" orifices. Welp either my measuring equipment is on a different standard, than theirs or they made a serious error, they actually need to be 1/2" x 3-1/4" stainless steel gas spuds with (10) 3/16" orifices.


1 - start with 1/2" x 5", 304 grade stainless steel nipples
2 - cutting them to 3-3/8" long
3 - the left overs
4 - the raw stock for the 35 needed gas spuds|505D2E86-E7E8-450C-BF73-5356FCE367F5.jpeg0886FD01-07A2-4AE5-AF6C-5C64CDBAC341.jpegC5180BC9-1946-4B13-AB0C-D77C2EDB48DC.jpeg8CBDB730-F522-4BD1-86F0-57BAA5824FE7.jpeg

cut the spuds to the finish length and rolled all of the sharp edges. They are now ready for the minions to install
