Need help sanding taper laminates

le5 · Post by **le5** » Tue Oct 09, 2012 3:35 pm

Hi I'm new to this forum and the shopsmith mark v. I recently bought a nice near new condition 510 with bandsaw,jointer,and belt sander. I got the mark v for building laminated long bows and recurves. I'm looking for some help in designing a jig to sand down taper laminates for my bow building. I need a taper of 002 per inch and my laminates will be .125 thick and 36" long. Any help would be appreciated.

Nope! You can delete a post, but not a thread(first post which creates the thread).

WELCOME TO THE FORUM!:)
Don't worry about the double posting - done it myself a couple of times:o .
For your sanding, think about vertical (drill press) position and using a drum sander. You'll also need a split fence, either shop made or purchased. A split fence will allow the sanding drum to "hide" behind the fence with only the grit reaching through to do the sanding. Shopsmith's shaper/sanding fence (part #555113) is a good one.

In addition to a split fence you'll need a taper jig. You can get lots of ideas about taper jigs from google, and by Using the search function (above on the solid red line) and searching for taper jig. These jigs are designed for rip sawing, but the principle is the same-- the side of the jig rides on the fence and the work piece is canted to the appropriate angle.

Because of the narrowness of your pieces you will probably need a guide strip on the jig and the work piece attached with double faced carpet tape.

Since you are already an accomplished bow maker, you should have no problem with a setup like this.

Thanks for the tip. It just happens I got a taper jig with the mark v. I was also thinking in purchasing a pre made laminates with tapers as my jig and use it like a sled to duplicate the taper with the headstock in horizontal position with drum sander over the table thinking it would be more stable and precise I also have a set of support legs to stiffen the table. It might also be cheaper!!!I build a few bow a year so I can re use the laminates over and over. I was always buying bow kits and working with rasps and hand tools. Now with the mark v want to make everything from scratch. And the bandsaw and belt sander will be indispensable for my bow making.
