Today I modified my balancer drill fixture in many ways. It was originally built to bore a 1 5/16” hole at 45 degrees through the wine bottle balancer, but it had a few problems. first, the Forstner bit would twist and lock up before it got through the board. The bit got smoking hot and expanded in the hole and did not retract easily. And the bottle did not balance level!
First I milled out the bottom of the fixture 1” deep for a sacrificial piece of wood so the drill is always cutting on all sides until it is through the piece. It just happened that as we were visiting our plywood guy, they had some crates out in the free bin and we picked up one. I broke it up and cut the boards into my sacrificial blocks. That crate will make about 70 of them. They were just about the right thickness too!!
Thanks to my friend , Kent Ball , from Idaho I found that spraying the bit with silicone helps tremendously in reduction of heat from friction on a Forstner bit. I sprayed the bit in my scrap barrel so it did not get around in the shop. Silicone can play havoc with finishing material!!
Then I modified the angle on the fixture to drill at 35 degrees with two little feet mounted on the front. I made a new guild bock for the new angle , too.
After drilling, I just knock the little bock out and insert a new one and it is ready to go again
One after another, the bottles, empty or full , balance much closer to level
The hole location is 8” from the base and the base is cut at 50 degrees.
Some of these will have the wine bottle inlaid and some will be lasered in.
I’ll post all the balancers when I get the group finished.
