My jig for making radius riser cuts
« on: July 07, 2007, 06:56:00 PM »
I know this has been covered before but it has been awhile.  I just made this jig with the help of Badlands.  I'm very happy with the results and thought I'd share.  This is so easy I can't believe I didn't do this before.

Bandsaw jig- clamp the block and cut.  There is 2 holes for 2 different radius'.  Top plate pivots on the bolt.
 

I have 2 guides on the bottem of the jig.  One sits in the groove on the table and one lines up on the edge of the table so I get exact placement of the jig on the table everytime.  This way if I want to come back and make another cut down the road it wall match up with previous cuts made in riser blocks.  
 

I cut the long radius first then the smaller one.  I can move the block right or left on the jig to create whatever type of flair I want when I cut the 2nd smaller radius.  Here I moved the block over about 3/4" to give me a bigger flair on the bottem.  Mixing and matching wood if the fun part.

On a side note I picked up some nice wood for vaneers from a flooring store for dirt cheap.  This was some left over Aulstralian Cypress from a job They practically gave it to me.  It looks like figured yew to me. I also got some figured maple.   Don't over look flooring stores for a source of bow wood.

Couple more things.  I use a 3/8" blade that is sharp and 6 tpi.  I tighten the blade a little extra tight so it doesn't wander.  Makes a smooth cut, no sanding required.  

I have to move the guide bearings up out of the way so the clamps don't hit.  I still didn't have a problem with the blade wandering.  Chad

They wanted to slide all over the place when I glued up the riser.  My wife helped but it was still frustrating (We tried not to swear at each other, at least not the real bad words).  

If it slides a little one direction or another it is no big deal since the radius is the same throughout the cut.  You should still get a good glue joint.  Chad
