Resaw jig

[iublue]

John (jteneyck) was so kind and shared with me a resaw jig he had made.

I had a LOT of veneer to make so the fact that the jig had to be readjusted after ever cut made me rethink the design. 


My version allows you to resaw up to about an 1 1/2" board without any adjustment.  I have done an 1 1/4" board and I know a thicker board could be done.

As you can see, I used extension springs and arms with a pivot point in the middle.
The larger rod you see protruding from the top is the pivot rod.  The smaller one is a stop rod for the arms.
The springs I used don't put a ton of pressure but seem to work just right IMO.  I used a threaded hook on one end of the springs so I can increase the tension a little if needed.
Of course, if determined necessary, the springs could be switched out with stronger springs.
2" wheels and then an arm that allows me to pull the rollers back to engage the piece to be resawn.  As you can see the I used chain to connect the arms with the pull back lever that is hinged.
I got the springs, rollers, chains, rods at Menards.

I cut up a BUNCH of walnut and 1/4 sawn WO and I am pretty happy with the results.

Looks pretty cool. You should put out a video on the operation of it.

I really like your take on it, Toney.  I've often thought tension springs would be a better option to allow for more travel, and your design proves that to be true.  So how does that handle work to pull the rollers back?  It's not obvious how it stays where it is; it doesn't seem to be attached to anything.  

Seeing your design makes me wonder if a slightly different version would allow those wheels to be driven, aka a power feeder.  I used a variable speed drive motor to power the feed rollers on my planer.  Doing something similar on the bandsaw doesn't look like too big a leap.  

Well done.  I'm sure you're finding the job of slicing veneer a lot easier now, and with more consistent results.

Thanks,

Power rollers would be cool.  I think the design would have to be modified again!

If you look at the third pic, you see chain going from behind the roller arms to the piece of walnut on the edge.  There are hinges between that piece of walnut and the plywood case.

In the first pic, you see the piece of walnut and an L bracket with another piece of walnut attached to it.
As I press that walnut towards the case, the chains are pulled by the hinged piece.

Works well!

I will try and make a video.

Hinges.  Of course.  Thanks.

Yes, it would take another redesign to add a power feed feature, but I think the same cantilevered spring arrangement you developed could be used.  I'm going to tinker around with a design, between other projects.

There are some great engineering minds on "this here forum".

Thank you for sharing!!!!!!!!!!!!!!!!!!

I took a short video and tried a couple of different ways to post it.

I couldn't make it work.

Sorry

The easiest way I've found it to past a link here to where it's stored online.  In my case, that's on my Google Photos site.
