Back to work- for real this time!

once again, I make a blog with the title "Back to work".

this time, however, it actually means something. earlier today I started working on the plugs for the resonators which will allow the aforementioned resonators to be tuned relatively quickly and easily.  creating them, however, is easier said than done:

these are the makeshift devices that were used for levering finished disks out of the hole saw. until these were created, it was very difficult to extract the disks due to an unfortunate design flaw of the hole saw.

this is the sheet of MDF/perfboard/whatever its called that I was drilling the plugs out of. You can also see the hole saw & drill press ready for the next hole to be drilled.

these are the nut/bolt/washer combinations that I was planning to use for the plugs. unfortunately, the bolts are too short...

a few ready-cut disks

the first plug. it consists of a foam disk, contained by two wooden disks. the foam looks (and is) rough, and that is one of the first problems than needs to be solved. we are thinking (after a conversation with the same uncle that laser cut the letters) that it might be best to send the foam off to be laser cut again, as this would be a quick and easy solution that would also be very precise.

the first of the larger disks.

last but not least, a comparison of the two disks. Though they don't look that much different from one another,  it is easy to tell the difference in sizes by the size of the bolts.

thats all for now! more to come in later days...
