From: "Boykin Ed (C)" Subject: COZY: My first hour and a question Date: Thu, 9 Oct 1997 11:07:54 -0400 Well, I officially logged my first hour of work on my Cozy. It was only 'prep' time spent going over the plans and making notes so I can figure what sections to work on in my apartment but it was still work that has to be done. After reading all the posts about templates on the net and reading about hot wiring and such in the plans I have a question..... In order to protect the plan sheets (just the large sheets, not the notebook plans) I had them laminated with some pretty heavy duty plastic(stuff with a VERY low shrinkage or yellowing over time). I did this since I bought the plans over 4 years ago (I have set #158) Anyway, my question is this. If I made copies of the sheets and laminated those, could I then cut out the templates from there and use those as my templates? I'f this isn't a good idea then I will probably still make copies and then place the cut-outs on some formica or other suitable template matereial..... Could you folks tell me a little about what you did to make your templates and what kind of pitfalls I should lookout for? One of the many things I have written down to take care of in my apartment includes making ALL templates.

But to summarize, the templates have been xerox'd (be careful of shrinkage about 2% average, make test cases to determine) and then the copies have been just cut-out and used direct or mounted on everything from plywood to poster board. Since you are only making one airplane from the set of plans your skill level at tracing, and cutting of the various materials will probably be the determinining factor for you. Personnally I let my daughter do the tracing for me (She is perfect at it, I'm so-so) and then mount on poster board with a spray adhesive (Aircraft Spruce (AS&S) carries a non shrink type).

For hot wiring, you really will need a very stiff template, such as formica, masonite, or 1/16" aluminum, etc. For the bulkhead and other templates, you'd be OK your way, I think. Check your copy machine for dimensional accuracy, too. >Could you folks tell me a little about what you did to make your >templates and what kind of pitfalls I should lookout for? There has been a lot of discussion in the past regarding template - sizes, methods of use, materials, etc. Check the archives - send email to majordomo@hpwarhw.an.hp.com with the following in it: get cozy_builders topics/airfoils.txt get cozy_builders topics/chap_04.txt get cozy_builders topics/chap_10.txt get cozy_builders topics/chap_11.txt get cozy_builders topics/chap_19.txt get cozy_builders topics/gen_info.txt get cozy_builders topics95/hot_wiring.txt get cozy_builders topics95/chap_10.txt get cozy_builders topics95/chap_11.txt get cozy_builders topics95/chap_19.txt get cozy_builders topics96/templates.txt get cozy_builders topics96/chap_10.txt get cozy_builders topics96/chap_11.txt get cozy_builders topics96/chap_19.txt get cozy_builders topics96/chap_20.txt end Once you've read and absorbed all these, you'll be well prepared to make your templates, not to mention create the "Templates" section of the COZY FAQ and get it to bil kleb :-). -- Marc J.

I don't think formica shrinks. You can get or buy cheap, scrap pieces from cabinet shops. It works great for hot wire cutting, very smooth edge is possible. The drawings seemed to work fine for me. The .001" tollerance some guys are describing seems impossible to maintain when hot wire cutting and glassing. Lets get practical, the paper plans worked for hundreds of flying aircraft. If you copy templates, verify that the copy is the same as the original. Text copies fine, but I found a great variation between copiers at a friends copy business. Mark the originals with a colored marker, so you can remember which is the copy..... For contour templates, for checking the canard and fuselage curve, I used the left over masonite from the fuselage side jigs. Don't use this for hot wire, too soft and burns. Make all the templates and cut them out. This is a great indoor project. Have fun... Steve Blank Cozy Mark IV #36 Still building......

The epoxy helps protect the template from wear.

I'd be there are still a lot of interior designers and architects using "white print" machines. I can't attest to the accuracy (or precision) but they do look identical when held up to the light. The copy is just for ref. anyway. I'm going to cut up the origionals (per plans?). Also try paying a visit to you local blue print equipment dealer. A case of soda and a couple of pizzas (& promise of ride) will likely get you a nice set of copies.... -- Best Regards, Paul Comte A Plus Computer Service, LLC. 5100 West Blue Mound Road Milwaukee, WI 53208-3654 (414) 456-9700 Voice (414) 456-9701 Fax Date: Fri, 10 Oct 1997 16:59:27 -0700 From: C Van Hoof Organization: Architect Subject: COZY: Copies and templates Hi all, Not often that you all tread onto my domain... The best copies can be made using a "flatbed printer" then if copied onto mylar or durester you will have a basically inert copy of the original - of course we don't really know the accuracy ( or is it precision :-)) of this item. Many of these machines have a correction facility on the X & Y Axis, the operator is not always aware so check your copy before leaving the shop - also assist in correcting (if need be). the instructions on the machine are pictorial and clear (for a Cozy builder anyway :-)) Second would be your "plancopy" - most printshops catering to drawing offices may use a drum type machine, the inaccuracy is of course there but is nearly negligible...depending on your Nth degree limit. There are some very good Xerox machines in use for this application (other brand names may also exist, but are not in use in South Africa). Thirdly there is your old fascioned diazzo (or is it ammoniac) type drum printer - this makes your original a "negative" - shines light tru' the original and makes a positive onto lights sensitive caoted paper - the image then fixed with ammoniac vapour. this would give you probably the poorset copy. in the USA you get this also with a blue background....the rest of the world has never figured out that this works better on an open air site..... Hope to have been of some help to someone, somewhere. chris #219
