Had some nylon tubing, gave that a go. I was worried it wouldn't let any water vapor through and thereby fail to cure. Hoping that they were similar, I decided to compare the vapour permeability for vinyl tubing and nylon.Vinyl tubing (actually PVC) 33 g/m2 over 24 hrsNylon tubing 270 g/m2 over 24 hrsLooks like I can relax! Nylon tubing is used to hook up refrigerator ice makers in Canada and the US. It is usually a translucent, milky white and much stiffer than same size vinyl tubing.Katou
If your making blades, you will be a fair bit of drawing out. Take a piece of square section steel to fit your hardy hole and weld a piece of 1" round about 2" long at a right angle. You might want a 3/4 round or 1/2 too. Smaller the dia, the faster it will draw.Voila, easy drawing tool.Katou

Fantastic work! There is an old design for a system like this floating around the net from Popular Mechanics, but yours is much better!I especially like the adaptations you have included for cold climates, such as the condensate system.J'espere que tu vas ajouter quelques mots a ton titre:"HRV" (Heat Recovery Ventilator)ETAir-to-Air Heat Exchanger. Ces sont les noms en Canada et les Etats Unis pour cette machine. Si tu utilise ces mots, on peut decouvrir ton projet vite et simple.Encore, tres bon fait! Katou
Word to the wise, magnetic files are very bad. Files cut metal, usually steel. Bits of steel get stuck in file teeth. Magnetic files fill up faster and are harder to clean. I used a magnetic knife rack to store my little ones. Bad, bad idea. I fixed it by replacing them as they died.

If anyone is looking for a great rocket design, here it is. This rocket will Backglide, which is really important. It is safer, and your rocket doesn't get trashed. Who wants to build a great rocket and watch it destroy itself headfirst into the ground? This addition of the noodle will also improve stability. The authors method of attaching the noodle is very solid as well.One question, how do you deal with the natural curve of the noodle? Katou
I would love to see how you did that! I need a microscope camera right now. How did you make the focus length correct?
What are you using for a camera setup? Your pictures are great!
