Making the cut and fitting the pieces

Not being an expert sawyer, I developed the method shown here for cutting and fining iny intarsia projects because I don't like to see gaps between the pieces. This takes a little more time, but it gives you an opportunity to compensate for minor cutting errors. My preference tor edge sanding is using the drill press with auxiliary table. 1 find I can change drum sizes and grits 011 the drill press faster than oil the spindle Sander.

'lire 2"-long sanding drums work very well. The largest one 1 use is 2"-Dia. x 3" long. A set of lour 2"-long drums, ranging from 1/2" to 1-1/2" in diameter, can be purchased, for a nominal cost. Having three sets with fine-, medium-, and coarse-grit sleeves will work most efficiently.

Lay the cut and sanded part on top of the one it will adjoin. Using the edge as » template, draw a new cut line. When possible, draw the line on the lighter colored wool, as it will be easier to see while cutting. A .5mm mechanical pencil does an excellent job for this, as it provides a thin, uniform line to follow for your next cur. Now you can see it doesn't really matter if your first cut was a bit off because yon have just created a new, identical cut line to follow.

While cutting, keep ihe blade on the outside edge of the pencil line. Check for fit, and, if necessary, sand the cur edge. It is helpful to use a light table or light box to see where there may he any areas requiring additional sanding. For reference, mark the areas that need to be sanded, as shown in the photo. For a small binding area, draw a "V" with a pencil. The area between the lines of die "V" indicates ihe beginning and end of the area requiring sanding. For a larger binding area, draw two perpendicular lines, with one at the beginning of the binding area and one at the end. Add a parallel line between the perpendicular lines, as shown in the photo, to mark the section to be sanded. These reference marks will help you avoid sanding the wrong scctions.

Whcthcr using a bund saw or scroll saw, the first thing you must do is be sure you'll be getting an accurate 90° cut edge.

A fter each part is cut out, use n hard-backed sanding block to remove the burr from the backside so the pieces will lay flat.

Use an oscillating spindle sander or drill press set up with an auxiliary table to sand the cut edge smooth with fine- or medium-grit sleeves. Always use the largest sanding drum practical for the piece being sanded. Using a l/2"-Dia. sanding drum on a long edge is more likely to create bumps along the edge than to actually smooth it.
