Excellent project. The video would be better with vocal instructions rather than sped up with a music track. I had to find the full one on utube and play it in slow motion. The instructible could have been better organized with how many pieces and sizes in total. Overall, a great project. However I am in the process of installing the combo lock in the front and attempting to mark the solution and it’s very confusing. That could use some clarity. Have watched it several times and I’m getting it, but it’s not yet clear. I’d also like clearer instructions as to which pieces get glued. Could use some better instructions with less guesswork. This is constructive criticism I hope. I would like you to explain the combination lock more clearly please
