Timber Framers Guild Forums Tools Tool Forum Our new toy...

Will do. We'll be on site the next week and a half, but once we get back, that will be on the to-do list.

Gabel:

How'd this rig actually perform?

half my keyboard quit orking in the la t eek, but once i get it repaired i'll give an update.

Ok, I've got a whole keyboard to use.

So far, it looks better than it works. We have broken the mechanism that holds the head up and sheared the pin that holds the main drive gear on the shaft, but we had a new pin machined and haven't had time to mess around with it again.

Gable, I have sheared off my shear pin a number of times, it is the weak link. I now use a simple cedar shingle nail, I have not changed it for a number of frames. I am using the 1-1/2" bit more in tough wood, spruce specifically, and even pine, it is just easier. What size bit were you using and the wood?

inch and a half in oak.

The problem is that the shear pin is overly complicated and is part of the mechanism for engaging the withdrawal gear.

The pin is tapered on both ends and held in the shaft with a spring (didn't know that till it came out -- never saw it, just heard it.) We've got to figure out how it all worked and then get a new spring.

We were using it during a one day demonstration/workshop. We finished the day with the trusty Boss Double Eagle.
