After completing my set of anatomically correct dinosaurs from MakeCNC, (the other three are in my office already), I then decided to make a pteradactyl as large as I can fit on my machine. Cut from 12mm thick MDF, it has a full wingspan of 3.3m, and physically measures 2m tip to tip, and 1.2m long. Despite being skeletal, it is realtively heavy!
It is destined for my daughter’s science class, to hang up in the classroom.
It would be cool to do one of the anatomically correct ones to the same scale! I really like the one that has its tail up in the air, which is the velociraptor. Be awesome to have one of those life sized. (That isn’t unrealistic, as they are relatively small as we saw in Jurassic Park). Might scare the bejesus out of any unwarranted visitors in the middle of the night. The plans only come with 3mm, so I’d have to accurately scale it to suit the 12mm thick material – job for another day.
Back to the large pterodactyl, (called a Flugsaurier Archosaurier on the MakeCNC website, which is German for Pteranodon, a type of pterodactyl). It took 3 sheets of 12mm x 900×600 MDF, which is not too bad, considering the size! It was cut with the Amana Tool 3/8″ solid carbide compression bit 46172 from Toolstoday.com I still ran it at 40mm/sec, but with a 3.25mm DOC. Tabs were 10mmx10mm (still 3D, which made them easier to cut by hitting them with a chisel) to hold the pieces in place during the cut.
What to do next……decisions, decisions.
