Having purchased a pantograph machine over a year ago I was eager to put it to good use on my Cambrian project. I decided to have the master laser cut in acrylic sheet at a ratio of 4:1. I could have cut out the shape by hand using another material but why make work for yourself when you can easily draw the artwork on the computer. When the artwork is finished it is simply sent to the laser cutter for cutting. The image I have posted shows three tender chassis sides machined using two different machines. 1 & 2 were machined on the pantograph and 3 was cnc machined on my Roland Camm-2 pnc 2300. The first two were done in 1.6mm NS before I purchased the cnc machine. Having done the artwork for the laser cutter I simply reduced the artwork to 4mm scale and sent it to my cnc machine for comparison. The first two frames are probably too thick for job I am doing and although I would have a nice rigid chassis the thickness on them would spoil the look of the chassis and soldering might be a problem. The last one is .57mm NS with a fold up tab to aid fixing to the tender floor. The chassis was cut out using a 2mm cutter and on the fold line I used a 45 degree angle engraving cutter. Unfortunately the fold line isn't deep enough so I will have machine the side again taking a deeper cut with the engraving tool. I will probably use my pantograph machine for the heavier cuts and the cnc machine were thin material is sufficient.
