Hi, I've seen other tube notcher software, but thought a few enhancements might be cool. I'm coming from a bicycle frame building background, but thought this may have some use for other folks involved in general metal fabrication work. The intent of course is that you type in your dimensions, print out a full size template, cut that to size, and tape it to your work. Yes, its not as cool as owning a machine to do the same thing, and it takes more time to hand cut and file a joint.. but think about the money you will be saving. You can save up for that inverter TIG machine you've always dreamed of owning. I will say, what happens to your fancy miter machine when you have to cut a very obtuse angle, say around 15 degrees or so? Good luck with that. The thing does a great job, takes up no storage space in the shop and its free.... but I digress...

The program is written in Java, and runs in your browser. There is no software to download (except possibly the latest version of Java... ) The system will self detect and correct your version. If you are on an Apple / Mac or Linux box, you may have to refer to the "About TubeNotcher+" menu choice for Java upgrade instructions. That link is at http://cobratorch.net (http://cobratorch.net/index.php?option=com_content&view=article&id=49&Itemid=59)
Enhancements:
--Distance reference lines added, so you can predict perfect tubing cut length.
--Alignment marks to aid in tape up.
--All dimensions shown right on the template, so you can figure out what is what.
--I added both inner and outer tube cut lines. If you are brazing and need an accurate fit, you don't want to cut off material that strengthens your product.
See photo 1 for typical output of a simple joint.
Sometimes the joint is offset, or the cut tube is larger than the base tube. I've programmed it to accomodate that.
See photo 2 for an offset view.
On a bicycle frame, some folks are creating unique tubular reinforcements. I thought I'd add an option to those reinforements by adding decorative tube ends. This might also work well for the ends of your tubing projects? You can program a variety of shapes and sizes.
See photo 3 for a decorative tube end sample.
