I'm trying to cut some coloured pencils into small chunks or slices, less than 8mm I'm getting good square cuts when the stars align but the key is consistency. My small rotary cutting tool is fixed with a 60mm cutoff disc. The issue is throughput too. I've tried using a 32tpi blade on a hacksaw, but the friction can cause colour bleed (coloured "lead" is waxy in nature) and it just takes too long. Over 100 pieces would be a conservative estimate of number required, not too mention the variety of colours, so may need closer to 1000. Are there any sort of guides I can use to push a row of pencils squarely through the cutting disc? If I strap them together, I can obviously push them off at an angle. The answer might be to live with it and sand them as and when they are glues together in patters, but I'll take Amy suggestions at the moment.
I was going to add this as another Comment but I figure it is actually an Answer since you've asked for suggestions.
If I were doing this I'd be using a Japanese-style pull saw with fairly fine teeth1, and a mitre box and with a stop clamped in place to ensure consistency. Each cut would take 1-2 strokes, literally about a second per pencil2. Triple that to account for the Law of Estimates™ and it still comes to only 50 minutes.
Factor in setup time, fiddling, occasional fumbles, moments when you stare off into space trying to remember why you're doing this :-) and I figure a full thousand would easily be tackled in one afternoon. Or 2-3 lunchtimes (it would be mindlessly repetitive and boring work, so good to spread it out).
1 A traditional dozuki would be a good choice but one of the saws from Shark would likely also work well and they'd probably be slightly cheaper. You want something in the range of 15-20 TPI.
2 Pencils are usually made from what we've come to call pencil cedar. It's not a hard wood and saws easily if you use a saw made to cut wood.
