What is the best way to make therion potractors? Years ago Martin S sent me some really nice robust ones. Ones I have tried to make since (by printing onto acetate and laminating the result) do not work well because my laminating sheets only stick to themselves, not the protractor material, so it opens up at the baseline and delaminates. Is it possible to print on one side of a laminating sheet then put two sheets through the laminator to encapsulate, or will my laminating sheet just melt in the laser printer? Maybe that could be done, but printed in a (cold) inkjet printer, so long as no water ever got in? There is also the matter of the correct 'floppiness/stiffness'. MartinS were nice and stiff (but robust). Laminator/acetate ones are rather floppy. So, how does everyone else do it? Also http://therion.speleo.sk/protractor/index.php only links to a 1:200 protractor. It would be useful to keep others available there and save people editing the metafont. Ah-ha - turns out that we have 1:250 and 1:500 versions carefully preserved on the CUCC site! http://expo.survex.com/templates/therion1_250.pdf http://expo.survex.com/templates/therion1_500.pdf And there are some US-units ones online. Collecting them would be a useful little task. Wookey -- Principal hats: Linaro, Debian, Wookware, ARM http://wookware.org/
I have printed it on a normal paper-sheet and then laminated with a "normal" Laminator by my work. This "thing" has worked for some years. But we have not so much surveyings in our Region. Once I have to make it new. But no problem - it is so simple to make it. BTW - many thanks for that utily! Now in the time of DistoX I have never used the protractor.

It was „printed“ on film in imagesetter machine (https://en.wikipedia.org/wiki/Imagesetter). Then laminated by thermal lamination films. You may find working imagesetters in companies which are doing silk-screen printing or screen printing. m.s.
I prefer a slightly modified version of the Steve Wells and Joe Zokaites protractor. A4 PDF with 1:500 and 1:1000 protractors at:http://hmg.three-tuns.net/media/surveysymbols/protractor-simple.pdf We've also tried some colour versions of the Therion protractor: http://hmg.three-tuns.net/media/surveysymbols/protractor-mix.pdf We use a colour laser printer, cut out each protractor, and then "laminate" them individually by covering them several layers of clear sticky tape. The tape needs to be wider than the protractor, so you can place the protractor on the tape and then fold the tape over along the ruler-edge side of the protractor. This gives you a nice smooth ruler-edge for drawing your centreline. We tried using a thermal laminating machine. It was fine as long as we left a border of laminate around the edge of the protractor. But if we trimmed it flush with the protractor's ruler-edge, then the laminate invariably started splitting after only a few trips.

It is probably better to use good inkjet and special transparent material. Inkjet is able to make thinner lines. And you may buy special transparent cold laminating tape. For example: http://solutions.3m.com/wps/portal/3M/en_US/Adhesives/Tapes/Products/~/3M-Sc... <http://solutions.3m.com/wps/portal/3M/en_US/Adhesives/Tapes/Products/~/3M-Scotchgard-Multi-Layer-Protective-Film?N=5003212+7574546&rt=r3> http://www.surfacearmor.com/applications/glass-surfaces/ <http://www.surfacearmor.com/applications/glass-surfaces/> Just ask for free samples :) m.
