 3D router carving
Hang on there Joe, I had no part in designing the template, it is, together with the special conical guide and cutter a commercially available kit, several different templates are available albeit at a price. the kit appears to be available world-wide, I recall Bj mentioning it a couple of weeks ago. The principle of the 3D template is quite clever, if you take a close look at the photo you will notice that the width of the cut-outs varies, so that the wider it becomes, the deeper the cone and cutter will go. I am only capable of designing simple type templates and because I generally make boxes and balloon clocks I make my templates 300mm x 400mm (12" x 16") and use boxes as designed by Template Tom and shown in several posts also in Tom's sticky. If I require a complex design that needs a CAD programme I contact Tom and say something like: "Tom,I bet you couldn't design a template for such and such" and knowing how pig-headed he can be I know that he will produce a drawing within a few days!
The set-up that you referred to I use as a fast method when using odd size templates. I hope this has clarified the situation and not sent you to sleep.Harry |
