Unique Woodworking Barn Beam Drill
This is a barn beam drill unlike any I have seen before. I have listed this for parts and restoration. However this could really be a working unit but it works very slowly you would need to lubricate the gears and the crosspiece and the sliding angle mechanism and you would need the proper size shank bits.
One of the wood uprights has crack damage. But could be used as is.
It has good handles with light drying cracks that move freely but slowly. The meshing gear castings are perfect the only part that's missing on the castings is a little bit of a chunk around the shaft on the top of the horizontal gear see photos. The shaft is very unique and when cranked moves up and down on the spiral that is machined in the shaft. The spiral is held in place by set screws on the crosspiece. This is very unusual they normally have a slide up gear track situation.
There's also a hole at the bottom of the shaft that has set screws to hold the drill bit. There is more control over the downward motion - actually complete control. This was patented in 1872 extremely ingenious for the time compared to the other models that rode on a gear track and dropped when you did not want them to.
They were very ingenious also. It is up to you whether this is a working unit or just a museum piece. It need some TLC and some metal and wood restoration. Some brazing might be required in the center of the crosspiece..
The wood does not have any dry rot. It measures 30 inches long 27 inches high 9 inches wide. I have seen about 20 of these and I have never seen one exactly like this. This would be a great item for any collection of barn beam drills.
