Cutting a 3-D reindeer on the bandsawThis little diversion started with Ronald Walters sending me some pictures and a video of making 3D scrollsaw reindeer ornaments. I thought that was a neat little project, but the pattern he uses is one that has been photocopied many times, and I wanted to provide a clean profile for people to use to cut their own.
So I started by importing a photo of the pattern into Google SketchUp and tracing an outline of the reindeer using the photo as a template. I know there are programs that can automatically trace an outline, but these outlines weren't really clean enough to even consider doing that, and it didn't take long to trace it out by drawing lines with the mouse.
Google SketchUp Pro has a feature to do intersections of solids. The free version doesn't have that feature, and I still haven't really had a need for the pro version. But the free version can intersect surfaces, so I just intersect them as surfaces and then delete all the surfaces that aren't part of the final 3D shape.
It only takes a couple of minutes to clean up the shape after intersecting, so it's not too bad. I only intersected half the reindeer shape to save time.
After cleaning up the intersected shape, I just combine the shape with a mirror image of itself. So here's my 3D CAD model of the reindeer, which I used for the reindeer plans. Looks OK.
Having come this far, I figured I might as well make one out of wood. But I'm no big fan of scrollsaws, so I just made my pattern bigger so I could cut it out on the bandsaw instead.
I glued these profiles onto a block of wood that is just the right size. The block should be a little bit thicker than the front profile (leaving at least 3 mm on each side). Ideally, the block shouldn't be any wider than the side profile.
It's hard going cutting this deep with a narrow blade, which is why the width of the block (vertical in this photo) should not be any wider than the pattern.
To make it around sharp corners, you can back up the saw and make a few extra cuts to open up a space to turn the blade around in.
Next I needed to re-attach the pieces together before cutting the side profiles. The quickest way is to just nail it back together. I'm putting the nails in the part that will get cut away later so I don't have to worry about damaging my final reindeer.
A nice touch is to give the reindeer some sort of nose. Some sort of bead to glue on would have been ideal, but I didn't have anything appropriate kicking around. So I used a black screw with a round head as a nose.
I'm really not that into the whole Santa Claus Christmas story thing. Where I grew up (in Germany), St Nicholas came on Dec 6th (along with his evil "knecht Ruprecht", who would threaten to punish the bad kids), and Christmas gifts were supposed to have been brought by the "christkindl". Although I don't recall actually believing that either!
Or you could make a whole sleigh's worth of reindder, these ones by John Burros.
