High precision Domino jig for narrow parts
« on: December 17, 2019, 06:27 AM »
Hi All,

My first post here, just finished a short video of my Domino jig and thought someone might interested. If you are curious how I manage to keep the Festool clamps from falling down by themselves I made a short movie of that as well. This is a feature I really think Festool should design into the clamps, should be very simple using a spring loaded small ball, spring clip or something else…

Edit2. Think I managed to post direct URLs to youtube videos [smile]

@Ola C - you address the problem of workholding for small parts in a most functional and flexible manner. Well done and thank for this contribution to the body of woodworking knowledge here on the FOG!

As gesture of appreciation we would like to send you a DBF-45 BigFoot for your Domino. If you would like that, please email me with your complete contact information and reference your FOG name, too.

An overhead laser to indicate center of mortise would be a nice addition.

Think my way of centrering the mortise in the second piece is way more accurate than a laser, check the YouTube film [smile]

Finally took the time to watch the video. I’m often reluctant to watch videos because so many of them waste so much of the viewer” time. Your video is a great exception. Very concise presentation of real information about a very useful invention. Well done!

Your way of locating the mortise on small parts is very accurate. A laser might help on bigger parts beyond the range of calipers but I’m sure you’d find a more accurate way to do that as well.

Thank you for your comments. I try to present my ideas in a short and (for most woodworkers) understandable way without too much "noise" that doesn't add anything. Really glad you liked my video.

I'll add my thanks and intention to steal that idea forthwith ;)

For times when you want to exactly mirror the main stop distance from the centre of the bit I'd wonder if something operating like a ruler or t-track with a stop on it could be used. It could reference from the side of the Domino machine and fixed fences with the moveable stop referencing of the main stop. Could be easier than cutting a reference piece indexing off the pins?

Thanks! I had something similar in mind, my idea was like a round steel rod housed inside the flip fence, retractable and lockable lengthwise, still indexing the pin. So, when it's time to flip the fence I slide out the steel rod until it stops against the pin, lock it and then flip fence. I assume the pins are better references for the center of the cut than the outer surfaces of the machine base are but I might be wrong.

Problem with the rod idea is that I want to index the base of the pins as they flex more further out and then my hole would end up very close to the edge.

Edit. Stupid me [smile]. I can place the hole further from the edge and have a pointer att the edge of the rod, indexing the pin. Will make a quick sketch.

Something like this. Pink is a round steel rod that runs in a round hole in the fence, rod has a T or L thing screwed to the front. Steel rod locks with green knob (which needs to lock from side as any protruding part will cause interference when flipped). Might be possible to run one rod through entire fence, if not I move it to other side for mitered corners mode.

Excellent video and idea.  Thank you for sharing!

When I get some tinker time I want to build a table like that.  For me it could serve a dual purpose.
1.  Domino for narrow stock - face frame, etc.
2.  Hybrid Pantorouter table - the stock one is limited in clamping options and small surface area.

Guess I need to buy a new router bit. :)

Any tips/learning lessons on positioning the slots (X and Y)?
Usually, I crank out something like this and have to make a version 2, 3, 4...
I put things too close together, too far, too big, too small.  A lot of making a useful jig is the 'Goldilocks' effect. :)

Yesterday I tested a concept of "integrated fence flip memory". I made a channel in the fence where a 8mm metal rod runs and can be locked in position. So, when finished cutting on side #1, I slide rod until it touches domino reference pin, locks the rod in position and then flip the fence. On side#2 the rod is used to set fence position and then slid out of the way.

Seems to work great but I need a harder rod ans softer screw and also a thumb screw variant that can be tightened without tools, already ordered [smile]

I want more "stops", similar to the two on the tool.   I want to build a tool similar to this where the domino is mounted on a "table".  I finally figured out that if I wanted additional "stops", I could put dowel pin inserts recessed into the table.  Put the pin where you want the stop, remove when you don't.   Clearly, yours is much more flexible.   However, I find that with dominos, they don't need to be super precise (like you would with a saw's stop), but they do need to be consistent.

Pins in the table means you have to center the Domino to the pins (left/right pins) when you mount it to the table. Could of course be done but might be trickier than it sounds. No the pins doesn't need to be super precise when it comes to location but they need to be very precise in terms of equal distance to the center of the cut on left and right side.

Ola, is there an reason for using the threaded inserts for the fence and not using the dovetail tracks to clamp the fence in position.

It looks to me like there would be a greater range of adjustment using the dovetail tracks but maybe that's not needed.

I built the MicroJig 360 sled which also uses dovetail tracks for their clamps. If anyone is wondering the Festool and Bessy clamps fit in the MicroJig dovetail tracks.

My first version of this jig, built some four years ago, hade through holes for the clamps holding the wood, mft style. To make a long story short, from usability point the elongated holes and threaded inserts at that time was a better option as clamping the fence in through holes required both hands on the clamp = No hands left to hold the fence in position while clamping. Also think I only owned two rail clamps att that time [smile]

With the current design with routed t-tracks it would work well to clamp the fence in the tracks as that can be done with one hand. Although I think the threaded inserts make it a "cleaner" solution with less protruding parts. Adjustment range is more than enough for my usage, and of more is needed I would add another pair of inserts.

I just wanted to resurrect this old thread and thank Ola C for a great jig.
I made it basically the same but used dovetail slots and Microjig's dovetail clamps which were gathering dust in a drawer as I've never had a need to use them until now. If I'd had some T Track on hand I would have used them instead as I have plenty of T Tracks clamps with the added advantage of swiveling at 360 deg so you don't need as many slots and they have auto adjust mechanisms Tried a few test joints including face frames and miters and they were all perfect. I've decided to use memory sticks in the short term instead of Ola's brilliant rod solution which I think works better with the pins than the paddles. Made about 12 sticks which should cover most of the joints that I do. Thanks again. As they say in my country "Your blood's worth bottling"
