Looks good with a lot of nice work. Make sure to have good explainations as questions wiil be coming. Back in the early 70's I built one almost identical in looks to yours in beer can size, black powder only. It was fun and no one but us saw it shooting in the field out back. It was in my cousins house when it burned down and when the firemen came upon the remains the officials grilled us for days. They were finally convinced it was not a modern motar. I bet the questions now days would include a complete background check and swat searches. Let's see some smoke and fire.
