The main objective was to create a trimmer that could but cut foam aggressively and not damage wall studs, which function as guides during the foam trimming process. To implement such a trimmer, S&D began with a chainsaw.
The company retrofitted a 14” electric chainsaw, made by Makita, into a chain-driven, t-shaped rotary planer. The business end of the planer, a series of multi-toothed cylindrical drums called “cobs,” is situated on a drive axel driven by the chain. The chain’s teeth, being flush with the cob teeth, function in a trimming capacity as well. The components that comprise the planer, assembled together to form the power head, are machined from solid pieces of aluminum.
