This tool is mostly meant to do smaller scale wood drilling, but can be used in a limited fashion on metal. The jaws will hold smaller round objects such as dowels or pipes. What size pipe and what material where you wanting to use it on?

Best,
Rutager

Because of the way the jaws are grooved out, you could put a fairly large dowel/cylinder(several inches, easily) in the jaws and drill down the center as far as your bit allows you to. If you want to insert a dowel into a bushing for the utmost accuracy, you'll be limited by the size of your bushing; the DJ-1 and 2 hold 3/4" bushings, the biggest I have is 5/8", which doesn't leave much metal. So probably 5/8" would be the max dowel you could put in a bushing and then drill.

Also keep in mind that the accuracy of the tool would allow you to drill from both sides of your stock and meet in the middle.

I hope this answers your question, if not, please let me know,
Rutager

In the picture below, the 45 degree jaws, the length of the jaws is: 3.62". The small jaw triangle sides are: 1". The large jaw height is 1" the bottom length is 1.92" the top length is 1.06" Where the long side meets the 45 degree side, it doesn't form a sharp corner, there is a .125" face ( a bit hard to see in the picture, but look to the back slot and you can see it.

The next step will be the slots looking from the longest side: the slots are .5" wide by 1" deep and go all the way through. There is really no reason for us to fool with measurments on where they land on the jaw, because they are clearance holes for the tool, so the best way to set them up is to clamp your drilling jig to the jaw, put in the 1/2" bushing and drill both sides- perfect location!
DJ-1 Jaws 008.JPG

The 22.5 jaws are even easier; no clearance holes. The smallest jaw is .55" on the longer side and .185" on the shorter. The bigger jaw is .96" on the longer side and .585" on the shorter side.

I hope I didn't miss any thing, if I did, let me know and I'll get you the information.

Rutager

That's what I intended to do in case of unavailability of the jaws.

That would be very kind of you.

Best regards.

Those jaws only came with the first generation DJ-1; they found that people weren't using them so decided to stop making them to help bring the cost of the tool down a bit.

I've never used mine, but I like having that option if I should come across a need.

I happened to need to talk to Michael at Bridge City today and he said they didn't have any of those jaws left.

I think you could make them out of wood pretty easy, and if you would like, I could take some measurements for you.

Best,
Rutager

I have recently received my DJ-2 Drilling Jig and I'm having fun time with it.

I was however a little bit puzzled not to find the blue and green jaws (as seen in the DJ-1 videos) in the box.
I then learned that these were not provided with the DJ-2 kits.

Is it possible to order these jaws separetely ? As a boxmaker, they would be of great use for me.

Thanks.

Side note, I have serious hand brace envy. I'm using the small brace on this page http://www.fine-tools.com/bohr1.htm Works well enough, but is quite small.

Thanks again Rutager.

I had suspected that you were using a quick clamp and that was why it slipped, I don't think the bit was causing any of the problem. I tried a standard Jorgenson "F" clamp tonight and I didn't get any slippage, although the bench vise makes everything so much easier.

The differences between our setups that I see:
- you are using vise, I'm using quick clamp
- potential bit difference.

You have likely pointed me in the right direction. Much appreciated.

Here's the set-up:

DJ-1 Mortise2 002.JPG

Here it is in the bench vise:

After each hole, I loosen the knobs and the vise, then slide the stock forward half a hole and re-tighten everything- repeat as needed.

I read this a week ago and was just about to do some mortises myself, so here's how I did my drilling: I layed out the mortises with my CS-2- more to keep myself from drilling two left sides or something else dumb. Then I put a stop on my bit, which interfered with the knob on the DJ-1, so I removed the knob, which made the bushing wiggle. So I made a wooden collar to space the stop and get the knob back holding everything true. I then put the works in the bench vise- which I do for most of my drilling and believe will be the answer to getting your set-up to work. I had no slippage and my mortise almost appeared like a router cut:

Here's the slot:

I was able to overlap as little or as much as I wanted- no sliding in the vise.

Thoughts on the best way to prevent this? Clamping helped but I still detected some travel.

The dream is still there: to quietly and efficiently cut mortises.
