Posts: 4,451 West coast of Norway | Export your design as a manual plot file, txt file, and it is quite simple. The panels are grouped, and there are two set of coordinates for each panel. One is for the egdes which you cut and the other set is the seamlines (these should fit within the cutlines, if not, something is very, very, wrong ) Manual cutting is best done in dacron, Maxx or Flex in my opinion. What material have you choosen for your design? | | | Re: Home sail cutting

Posts: 1,449 | As Rolf mentioned 5.4 would be OK but you could probably go as low as 4.2 in a yarn tempered rip stop dacron. The full length battens do a lot to protect the cloth in the jib as they tend to stop the jib from flogging. As far as cutting dacron just like cutting glass fabric I have found a rotary cutter very quick and handy. It is also really good at cutting uni directional carbon without disturbing the fibres. Uni Carbon really doesn't have anything to do with making sails but it is handy to know as when working with Uni carbon it does not like to be handled any more that neccessary. Good luck with the jib.

Many people believe their plotters are perfect but learn otherwise the hard way. | | | Re: Home sail cutting

The nasty part is that the errors are not consistent or repeatable to take them into account and compensate. Of course it depends on machine also, but most of the errors are some times there because over a 5m lenght of roll printed the mechanics inside heat up and the roll will travel more on a dilated feeding roll. Usually errors are in the long dimension, the left-right travel of the print head is usually very accurate.

Posts: 1,449 | Dave, My good wife uses a rotary cutter to cut material when she is making a quilt. Basically it is an extremely sharp wheel with a plastic handle on it. Anything you push the wheel over it cuts. I bought one ($45 AUD) and keep it in my workshop for cutting glass and uni carbon. If you need to cut kevlar you can't use it. You can only use kevlar shears or special scissors. Regards, Phill

Posts: 1,449 | Rolf, Only diff is mine has a royal blue and black handle. Basically the exact same thing. Very handy when cutting lots of cloth.
