Thanks Paul and Steve,
Gotta give credit where credit is due Paul - the angle grinder thing was your idea and much appreciated. Let me know when to start sending the royalty payments
I measured the inside after firebrick install as the replacements seem a little thicker than original and my numbers came closer to 40 pounds than the original 60. Since it's a workweek and no use in heating the garage when not able to enjoy it, I let it go out and plan to just dump coal in and see what it does end up holding. Will pass it on asap.
It only burned part of Saturday and all day Sunday so I left it on a light cruise during the day Sunday. It did ok for the 600 sq. ft. quite drafty garage. The barrel temps measured with IR were warmest about midway up the sides at 500 degrees. The other areas - top, ash door, etc. were 300 ish degrees or cooler. Of course it's just directly piped into a 6" masonry chimney so I'm sure some damping will improve things but had to play and didn't have the materials on hand at the time
