Made one to skive lams for joining in center for one pc bows this AM,been thinkin on it for a while(very dangerous,me....... thinkin)!
Easy as pie and makes perfect skive joints. Would also work for overlays I suppose...
If doin again,I might make the bottom board a bit longer,I had to slide it down the table to clamp before I screwed the fence on. I added the 2nd fence to support the first,figured I could slip a paper in to tune for square,but didn't have to.
Here is the side that goes to the disc...

Here it is mounted up on the disc sander,just run both lams in til the one next to the disc is paper thin on end,then trade places and do othe other one. Easiest skivin I've ever done! :)

Summertime tool building has been taking my time up, too, Kenny.
Cool jig, thanks for sharing.
cool jig, thanks for sharing with us.
Makin jigs is fun. Know whats NOT fun? Sanding a skiv joint with my belt sander and having the lam grabbed by the sandpaper and launch it accross the garage. Am I the only person this has happened to?
Kenny, interesting jig. But could you show a pic using it? I'm slowly getting to the point where I want to attempt making my own lams.
Thanks,
Stan
@tommy6,
They sure get some distance sometimes, looking like a 80 mph knuckle ball! LOL
Good one kenny!
I do a similar setup and put both lams together and sand the skive joint on both at the same time.
Tommy6, I have launched pieces of wood out of almost every one of my machines at one time or another. Sent a piece of Black Walnut off of my router table through my garage door window one time. Sure is a wake-up call and thankfully I haven't been hurt yet after 35 years of woodworking.

I've launched a few lams across the driveway a couple of times. I do the classical look up to see if anyone was looking thing. I made a taper jig similar to Kenny's jig for arrow nocks and point ends.
Very cool! I have been needing a better way to do that! Thanks!
Nice simple salution. Thank you for the tip. Good Hunting Knifemaker

First I've seen this thread but good information. My initial thought is, "Wow, your skive joints have a much greater angle than mine!" I just sand on a 45 but can see where the longer joint glues up easier.
I do the same thing with boards up to 2 inches sq and I use a jig like yours on the table saw to cut the initial cut then put the jig on my disc sander and smooth up the finish and you are correct it makes a perfect joint every time. On thin pieces like lams I also just use the disc sander.
"skive" this term should be in the "newbe vaocab section"
What is skive? :confused:
in boat buidin' we refer to that as a scarfe joint- and the min. angle ratio should be an 8:1 but up to a 12:1 is really good, after that it is just too much effort for the minimal increase in strength.
with bows, as it is a sandwich lamination, i geuss its not so critical- thought i would just throw that little bit of info in here- in an already excellent thread.
thanks kenny.
Thanks, good idea. Eric Krewson posted a similar jig for tapering the ends of arrow shafts. He fastened a piece of wood on the bottom of the jig to fit in the miter slot on the disc sander table, so it could be removed and always align perfectly when put back in service. Works like a charm. It is always interesting to see how other people do things. Bue--.
