Intro to fabrication – Week #5 – Materials

This week we need to build something out of two materials, without using plywood or acrylic. I went to buy some copper at Blick store for our fabrication class, and had this idea in my mind to create a pencil if I’ll find nice lead tube. I found a few tubes that I could use, and decided to get the cheapest one and to make a quick test. I got some scrap wood and cut it to be a long straight rectangle shape, using the band saw. I sand it to have 6 equal faces, (tried to at least…) it always had one of the sides better than the other, but I figure I should measure and mark until where’s my sanding should continue. The next step was to create a hole for the lead. I measured it with caliper and got 17.6mm, while 1/2″ spade bit will cut only 17mm….

I cut it with the spade bit anyway, and then Jesse, that lended me the caliper, offered me to sand it with an acrylic tube covered with sanding paper. I did that, and could match a bit the width of the hole to the lead. I needed to push it in, and the lead is quite soft, so eventually 1″ length of the lead went in. I then sanded both of the materials together using the sand machine as a sharpener.  I guess the for a quick tryout I’m satisfied with the results, and should thik about paint it or laser cut it later on…

  1. Nice work. Where did you buy lead rod?

    The fit between the two materials looks great, very tight tolerances.

    I like your technique of recording and testing your laser etches.

    In the States we have a brand of pencils called #2 pencils. Might make for a funny laser etch
