The engraver by universal engraver is interesting, quite large. Collected a person familiar with production. It took about an hour to assemble. In general, in the form in which he comes, the engraver is quite toy. Tried to engrave on veneer, plywood, composite sheet (yellow). We plan to deliver radiators, stationary cooler, power supply is more powerful (someone advised in the comments below). We will try the skin, leatherette, cardboard-add to the review.
