   Like knuts said the site is great. Found it through google before I saw his post. Had been there before and wasn't ready to do it at the time, forgot about it. Gotta try it now. Seeing the clips brings it alive. Thanks mvflaim. Check out http://woodgears.ca/joinery.htmlPete

   Not bad, but I didn't see a laser guide on the jig. And, shouldn't there be some sort of motor drive on the positioning screw? ;-)

   That's funny! My first thought after watching the video was hey I bet I could motorize that!

   Everytime I look at the video I can not for the life of me figure out how the guy is able to achieve perfect spacing between the fingers. It seems like he just knows to turn the crank three times in order for the blade to line up to cut the next pin. I didn't see any sort of index spacing pin in the video or in the plan. It has to be the size and number of gears on the crank that allows him to achieve such perfect fitting. Anyone know how it's done?

   I also looked at it several times and I'm sure it has something to do with the number of crank turns. If three turns of the crank moves the sled about half an inch, it's reasonnable to conclude the number of runs is the key. After looking at the plan I realized that the crank spins a gear that turns a threaded rod which moves the sled. Any small variations while turn turning the crank can't affect dramatically the movement of the sled.

   Well thought though!

   Yeah, I thinks that's how it works. Ingenius design. You would definitely have to be an engineer in order to figure out how big and how many teeth your gear needs. Luckily, he has a gear formula within his website.

   Several of the biggest inventions have been created by... mistake (Viagra being one ot them). I don't know if he had in his mind to crank 3 revolutions to get his width of finger joints prior to making it.

   For sure it was as fun to watch as seing the results. I never saw such nice joint made in so little time!

   Serge..

   Sorry for the late reply

   Look here. Designer goes into detail about how it is made. I believe he sells plans for making the gears. I di not look further. I get the plans for the gears but I'm out of money for a few months!

   All the info to make the jig is on the site somewhere. That and his tenon jig are on my list this summer. Anybody know of great jig sources like this?

   Habilis,

   Check this "jigs page" of my website. You may like one or two.

   Here's one of them, which I call my "rout through jig". But it does more than that.

   Serge,
   I like that jig, definately on my list. Nice explanation and site in general. Makes me feel better about my table saw. So, you're French? Thank God you added the English translation. Took French in 8th grade, watched boring movies of dorks riding around Paris on mopeds. Got nothing out of the class but a bad grade and the chick with the biggest frontend in junior high. Course, I didn't put anything into it either.Great day!

   Habilis,

   This jig is always on hand sitting on the outfeed table of my tablesaw. Glad you like it since it's very usefull and helpfull.

   I don't get why you feel better about your tablesaw?

   I've decided to write my website in both French and English to reach more buddy woodworkers. I even had comments from Brazil, in a mix of French, English and Spanish. T'was funny! In fact, I write the English part first and then translate in French, which is easier to find the proper words, since I'm French.

   I also took English at school but it's not there where I learned best. In fact, it was by watching "good" movies, then during my carreer in Human Resources.

   Serge,
   Because of the jig you made turning your friend's circular saw into a table saw. I mean the jig was good, but ...
   Yeah, those movies in 1970 would not make anyone want to go to France. Too bad, my loss, did pick up a bit of Chinese later.Smile,

   made one this week and cut my first fingers with it this morning.

   I used 1/4 x 20 TPI threaded rod, two and a half turns being 1/8" I did run it through a die though before I mounted it, as maybe it was damaged in the store, but the nuts didn't turn smoothly.

    

   For the mathematically perplexed, the gear on the threaded rod had 16 teeth, and the drive gear had 40, so one turn of the crank turned the threaded rod 2.5x

   Cutting the gears was interesting, but got it done even if they look pretty rough, they is real sloppy, but that didn't seem to matter.

   Instead of using the bandsaw, I used a laminate trimmer with appropriate size router bits mounted on a spare TS insert so I could use a little sled to cut the teeth

   Setting dado blades required digital calipers, and shims so that I was a few thou over 1/4", then things worked out ever so much like the video

   Awesome !!

   I couldn't find the digital camera, so I borrowed my wifes...

   thank god for good wimmin eh!

   the first shows a top view of the jig

   The second shows a finished box joint, the proof of the puddin is in the eating eh?The third shows my hack wooden gearsI am forever indebted to Matias for sharing his jig and providing the gear layout website.

   The things I did different.....

    

   I used 1/4 20 threaded rods not only cause the local borg was out of the recommended 3/8 rod, but 20 tpi made gear calcs a lot easier.

   2.5 turns makes .125 inches, and that is copacetic(sp?) with saw bladesand dado sets...

    

   skipped the dovetail guides and the spring hold downs, just made a trough with spacers, all cut at the same time, drilled the pilot holes so that they all aligned, although with 1/4/20 rods, you could be real sloppy and it would work out OK; nonetheless, I did try to be as precise as possible.

   The lack of dovetails aand springs, well I thought that might be a problem, but as the sliding carraige was made just a 32 inch smaller than through it fit in, and the thrust is to the back of the apparatus, the only force which would give me problems is that the saw blades might lift the work, but such was not evidenced as a signifigant problem at all.

   Used 1/4 x 3/4 bearings and the slit hold down shown, but I used bolts screwed into undersized holes. Used Forstner bits to drill part way through, so I had a shoulder for the bearings to rest against.

   at one end, I used a 1/4" fender washer to hold the bearing down, and that was enuf.

   I did possibly have some damaged threaded rods, as the capture nuts  didn't thread easily, so I did run the threaded rod through a die before I assembled the beast, rather than have to dissassemble it later. I was suprised at the amount of metal shavings got produced. Doon't forget the oil eh?

    

   Those are the significant variations.

    

   Hope that helps for the next fella..

   How long did it take? What does "kift" mean? Pete

   cowtown | Apr 30, 2009 07:56am | #30

   thanks for noticing that.

    

   Kift means lift

    

   The box took but an hour or two to do, cuttingthe gears took a few hours.

   did you see the end result?
