I've got everything ready to turn the drum and sand it to its final diameter.
It's not that a simple job to reverse engineer someone else's work and make changes in the process having only video and next-to-useless sketch to work from. I don't even want to think of the number of changes and mistakes that I've made in getting this far [Geez, I hope my wife doesn't read this! ;-)], but it is very satisfying to see the project coming along :-)
As you can see, my drill press was down so I had to come up with an alternative method to make the MDF round donuts. These octagon donuts were cut out on my scroll saw and then rounded under power with a hand file...it can be done for those who don't have a drill press. The center hole can be drilled out of the blank with a hand drill.
