Custom counterbore for working w/logs
Hi Everyone,
20 years ago we were building a homestead in the mountains of West Virginia. It was a shoestring venture to say the least.
The plan was to start with a couple of mobile homes & live in them while we were building a more permanent place.
Flat areas didn’t exist so I needed a way to save space – build the shop under the mobile homes. Except I wasn’t building a basement.
I had to make this counterbore to get flat washer seats on the sides of logs. The head of the c-bore is Ketos tool steel that I happened to have but it already had a hole that was bigger than the bolts I was using. So, I annealed a truck axle & turned it for the pilot, shank & interior segment of the cutter teeth. Then I re-heat treated it all w/a coal fired forge I had taken w/me.

This shows how it makes a washer seat.

This tool is a drill guide so the holes would come out straight on the opposite side of the log.

These helped me do this:

The poles were sunk 4 feet to a foot thick concrete footing & were going to continue up & over the mobiles for a post & beam structure that would envelope the house above & shop below.
When I took the above site photo I was standing on the roof of a 40 foot refrigerated trailer I used for my shop.
Not too bad considering I worked alone w/o cranes, although the old military truck sure got a lot of use!
