Well, I got bored the last few days. Although I ordered a original barrel jacket from sarco, I decided to try my hand at making one. The pipe is 2" OD 13gauge. Its a hair bigger than the original 1 7/8 but, my selection of steel around here is limited. Laying out the holes was a bitch. I used a 5/8 hole saw like the original but had to increase the hole distances because the larger diameter pipe. I made a stupid mistake of trying to drill thru in one shot but the holes were really crooked on the other side. So, I had to drill each hole individually. My ugly misaligned holes will be on the bottom side!
Lesson: its cheaper and much easier to buy a jacket. BUT, what's the fun of that!!
