DJ-1 Offset Holes…Food for Thought/Comments Welcome
“Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.”
—Antoine de Saint-Exupéry
For those of you who have been following the idea train regarding an offset hole attachment for the DJ-1, you have seen a couple of ideas pop out of the BCTW skunk works.
I like the micro-adjuster, I like that the latest permutation is sexy, et al.
But I remain unconvinced it is the best idea for drilling off center holes. How about this idea-
Speaking to both DJ-1 owners (and there are many of you) and potential DJ-1 owners, what if we were to build what looks like an identical DJ-1 but the bushing head simply floats on the two beams–we ditch the self-centering aspect?
Current owners already own the bushings and perhaps the Universal Jaws too. This version simply gives you the ability to traverse the head back and forth across the capacity of the tool and drill offset holes to your hearts content.
Personally, I find the nose cursor very useful and have no difficulty aligning centerlines to the nose cursor. We will also be able to add both metric and imperial grads to the top of the arms indicating the centerline difference from the EDGE. Are you listening to your echo David? And get this, if we etch the same rule on each beam, you can center the bushings by using the beams like a centering rule–same reading on the left and right and the bushings are centered, and exactly the same distance from either edge! We very well may be able to both systems on one tool creating one SKU. Metric for centering is easier and preferable in my opinion.
Second, this tool would cost less to make and perhaps broaden the appeal in the market–just thinking out loud here. It would be an elegantly simple solution in the most compact form–and fast. These three criteria appeal to me.
For current owners, we could offer it without the orange jaws, four screws is the difference. All of the pulleys go away, the cable assembly, and requisite slots and tapped holes disappear too-these are not insignificant costs. Our thumb to the wind guess at this point is that this version would cost about the same as the micro-adjust version–maybe less.
We disassembled a DJ-1 and created a working version of this idea and I like it. It will be even better with the grads.
If enough of you chime in, I will mock one up when I get back from my magic class in a week.
