Checking to see if thiers a special heat shrink film they use on main blades, or can ya just get some big shrink and use a heat gun.

If that's the case and the blades are typically semi curved at the tip how would ya terminate the tips?

He must be talking about wood blades. If so you can seal them with CA.

I have NIP-unopened-white, main and tail shrink for a 50 size.

It's from 1982 though, but still NIP!

You can have it if you want to pay postage.

I'll have to check, I may have some un-built sets in hobby stash. I'll make you the deal of a lifetime on them...you know you want them.
If you don't fly them you can turn them into a nice wall clock.

Hi all you wood blade builders. The Vintage Helicopter Association has had a booth and display at Our June fun fly and IRCHA, along with other events. We show wood main and tail blades. I had a newbee ask me what kind of blades were on a display heli. I showed him how we sand, seal, paint, cover,(with contact paper, or monocoat trim sheet). Then we get to balance. I always check my balance at different stages of the build. Some wood blades have lead weight so you can build the blades right on spec. The heat shrink came a little later and as you learn how to hold it with needle nose it works very good. I feel like I could teach a class on this lost art of building. Not to even talk about wood servo trays. This is why we started the Vintage Helicopter Association. To share the knowledge lost to "ready to fly" , Plastic helis. Don't get me wrong. I fly the newest stuff too. Please support our/your group. Membership is only $20 yearly. Hat and shirts at $20 also. See us here under "out of business", Events, and facebook. Thanks Mark W

^This!

I still have the last pair of woodies I made. It took me forever to get them to balance both the span wise cg and weight. The heat shrink part was fun and easy. It was much thinner than lipo pack heat shrink.

tip....

For heat shrink on wood blades it is easier to use a steam kettle than a heat gun. You will not burn through the rap. With steam you can get it as tight and not have to worry. Take medium CA for the tips and wipe them clean..

hope this helps.

I remember they used to make a vinyl sticker that you could wrap around your blades instead of shrink wrap. You started just before the trailing edge on the top side and wrapped the sticker around the blade and cut it off at the trailing edge. Then you just CA'd the tip and root to seal them.

If you skip me I can't play!

Forgive me, but "back in the day" I was building planks, so I never learned the art of wood blade building (although I built many wood servo trays). However this thread is very interesting. I didn't realize you could Monokote the blades. However that makes perfect sense. But I'm curious. Did you build the wood part yourself, or was this purchased pre-built? If you built it yourself, kind of wood did you use? Spruce? Balsa? Did you buy the long square stringers from the hobby store? How did you laminate it together? Epoxy? CA? How did you shape it? I can't imagine trying to get symmetrical blades using a sanding block. I want to know more about this "lost art".

I need to find my wood blade collection in the attic and snap some photos.

I only assembled pre-made wood blades. Essentially, on pre-made blades you trim the lead weights and glue them in, sand, cover with either a wood preservative, heat shrink, or some other type of covering, and final balance. I think I may have used Balsa-Rite on a few sets back in the day.

Usually the leading edge was hard wood and the trailing edge was a much softer wood such as Balsa. I think I have at least one set that was several layers of lamination.
