Bridge City-2 Unbelievable Blems, The New DJ-1 Universal Jaw
Friday, April 30th, 2010As far as blems go, Michael has set a new kind of record here… below are the first two CT-16′s he assembled. What do you think Donald Trump would say at this point?

After spending most of last night in the bowels of the internet (thanks to all who have shared their views) I finally decided to finish the Universal Jaws for the DJ-1 Drilling Jig. As of this writing, prices and availability are yet to be determined.
I am excited about this tool, and it has a growing and enthusiastic user base which is cool. These jaws take it to a new level.
The picture below will allow angled drilling on flat, square and round stock up to 45 degrees. It is fairly straight forward, align ONE jaw (flat stock rides on top of the jaws) with a reference tool. Place anything reasonably round (a short piece of dowel or conduit works great) in the “v” groove, close the jaws together and tighten the second jaw and now both are planar. It would be fun to offer a drilling challenge pitting this device against a drill press…
The two little jaws below index to the plates and provide a pivot/axle for drilling radially. They slide up and down the plates and will allow you to make “Tinker Toys” if you will up to 12″ in diameter. Your stock spins on the 1/4 diameter axle and if you need a larger diameter pivot, make your own by center drilling dowel on the DJ-1 and cut to length to bush the 1/4″ metal shaft.
The image below illustrates the set-up for radially drilling either concave or convex shapes. The hole will always be radial and there is no limit to the diameter–you could literally drill spoke holes in a Conestoga wagon wheel if needed. You can drill hoops from outside in or inside out. It is simple, fool proof and more accurate than any method we can think of.
The attachment below should be of interest to toymakers, clock makers, sculptors, and any wood worker with the need for indexed holes. There are five index rings (64, 60, 48, 36 & 28) and just about every possible combination can be generated with these five choices.
There are three main pivots for the wheels, and if one needs to index larger diameters (this will accommodate up to 14″ as shown) it is possible to gang plates together doubling the capacity or more. More on this later.
Stock can be held to the index wheel either with screws or, with a small strip of double stick tape which would be my preference in most cases. Again, arbor diameters are easily bushed by making your own bushings.
Couple of other timely pieces of news.
Our early bird offer regarding the CT-17 Dual Angle Block Plane which includes a free O1 iron in addition to the A2 stock iron, expires this coming Monday, May 3. FYI.
Also, we are producing a limited run of the skeletonized HP-7 Shoulder Planes (50 to be exact) and we have 10-11 that are still available. They are not for everybody but both of these tools are something else.
These are not available on our web store but further details are a phone call away by calling 1-800-253-3332.
Lastly, next week is the start of summer hours here at Bridge City. We work 4-10′s Mon-Thurs (phone staff works 8-5) until Oct. 1. Five months of 3 day weekends in Oregon is about as good as it gets.
I know I am looking forward to the change.

PS: We made the blems pictured above to make ourselves laugh. Hopefully you too got a chuckle.
