The MarketPlace Wishing Well F.A.Q (Last Updated: 2025 Jan 09 5:00 pm)
Have an idea for a MarketPlace product? Would you like to let the MarketPlace Merchants know?
This is the place!
Make sure you check The Product Showcase Forum and The Product Showcase Art Gallery.
Sorry about the delay. Reality got in the way and I had to deal with that first. Anyway, I have several pics with two I think slightly better than the rest. The first (above) has the mechanism broken down somewhat so you can see how it is made and the other (next post) shows it all together with the drive belt but hides details that are seen in the first. It also has a slightly oversized handpiece for some odd reason. The other two (two posts after that one) are how the subj ... er, victi ... er, patients would see them in the offices.
I hope this helps.

Trust me, no one did but that's what was used from somewhere around 1875 when the electric drill was invented to replace the foot treadle one until the early 60s when air/water ones came into use. Even so, the electric ones continued in service for things like cleaning at elast into the late 80s and I wouldn't doubt a few are still in use for that.

I'd greatly appreciate it. It's going into a 1930s medical center so the third one wouldn't work however it helps show how they were assembled. Kind of.
Something that's not obvious is that the pulley thingies aren't actually attached to the arms but rather are free to swivel as the arms are moved around. This allows a tremendous freedom of movement to the handpiece. Also, on some the motor moves with the first arm rather than has a set of pulleys between it and the arm. In both cases, it's free to rotate on a pin through the base.
If any other questions come up, I'll try to answer them. I'm also looking for one IRL to attach to a watchmaker's lathe for detail work. If I find one before anyone starts a model (not really likely but I can hope), I'll be able to take detailed photos to help with modeling it.

I'm looking for five aircraft and an old fashioned electric dentist's drill.
The five airplanes are the T-6, T-28, T-33, T-37 and XP-59. I've flown the first four and my father was an engineer on the fifth.
The old dentist's drill is the kind that was used before the air and water drills came into prominence. They were actually still in use well after for cleaning etc which didn't require the newer equipment and may still be in some offices.
Thanks you all and to Renderosity for a fantastic site.
