I got a bunch of supplies and tools this past week (smokey joe gold, stainless hardware, riveter, expanded metal, terra cotta, yada yada). I already had the imusa pot. Although I'm missing extra grates. Went to both lowes and Home Depot but no luck so ordered on Amazon. I saw one of the builds here which talked about cutting a 18.5charcoal grate to fit down low. I have a couple questions about that. First how do you cut the grate? I bought a black and decker jig saw to cut the pot. Can I use it to cut the grate? As an alternative I noticed the smokey joe charcoal grate fits with plenty of space inside the steamer ridge. Is ther any concern about cutting the bottom hole a bit smaller than normal and using an extra sj grate to support the diffuser? Hopefully the question makes sense and I'm sure I'm missing some downside to trying this I really liked the idea of using the bottom to support the diffuser rather than drilling extra holes. Plus the extra sj cooking grate fits perfect on the steamer ridge as a second level.
