old dodge dart
A friend of mine in HS had a '69 Dodge Dart with a 340 4-barrel.

It was light and damn fast....

Looked plain jane and would fool people with its acceleration.

Mine was a bad ass 69 283 with 2 barrel. (It was a hugely embarrassing piece of chit) Stupidly i rebuilt the engine, put a 4 barrel on it. It was still an embarrassing POS. Fortunately i learned a little so the next few turned out much better.

There was a guy down the street who had a nice 340 Duster without any crappy home made fiberglass. 40 years later i am still jealous.

That dart was actually more embarrassing than my HS yearbook portait. (1979, dork trying to be cool. yea, it was that bad)

there are people with experience and then people with experience. Those that know how to dupe customers and employers by cheating the process and those that care a f about the final product, the former do not. Many many years ago I walked along a row of factories a couple of which turned out 22ft sailboats. I remember taking a wad of mat outside one unit and stuffing it in my pocket to do what with I don't know. Got home and began to itch.

Do I have experience? worked for Audi some years back straightening out a very sloply built International Auto Show pavilion piece lot, idiots who made them made a near catastrophe I came in and rescued, no thanks at the end of the day just a f off from one partner. (they got their come-uppance since).

Do I have experience, here, I was hired as a laborer but saw how dismally crafted the parts were I put 40+years of experience to work getting these things near perfect, these are my work of a few years past (there is more than this)

that's Audi,
and next is the trunk of the Intel tree at a Las Vegs e convention back 2013 or so,

closer look at the huge hockey helmet I carved and was cast into a mold, this is a pull and pics of the plug are in my gallery,

here's a very rough 380/420 plug I just nearly finished shaping last week for casting,

have to do a pre-mold lay up to see if it fits fine or not, yeah but I still know nothing, like how people can be agents of disaster and misery even among there own employees, siblings and closet pals.

This isn't about me of course, remember it'll be messy and sticky and dusty and can become tragic very quickly without prior knowledge of material handling. If you wanted you can make a clamshell mold out of plaster, wax the heck out of it and pull a small number of canopies from it without tons of worry and messy fiberglass mold making questions. Sand the exterior with 220 grit and primer before painting, no worries about gel coat either if you want to skip that step.

Ohh yeah, all I really replied for was to say the pva is used because it is water soluble and your supposed to let the water break the pva down not yank the part out of the mold risking taking parts of the mold with it.

(while I worked for the shop on the Audi job I was at WAR with my employer on how the so called "expert" glasser was an imposter and fake when I challenged them on how idiotic his techniques were compared to mine, btw. They since have been utilizing some of my techniques as I discovered recently, again no thanks whatso-ever non at all).

back to you.

I was looking for a Hughes little bird canopy for the helimax Axe that I'm trying to bring back to life. I have finally got to cleaning the actual cobwebs off of it(literally). Took it apart a few months back,then just didn't want to get addicted to the rc heli thing,put it in a corner, then for some reason ordered the repair parts.
Ran it, swash separated last night.

Canopy lost priority.

back to you.
I was hoping to see some of the helicopter canopy plugs and moulds you’ve made.....
That is what the topic is about....

Don’t see what anything you’ve posted has to do with the topic....

Been there, done that and old enough to know better.....

plugs and molds? on it's way.

A few life experience anecdotes aren't out of the topic as some would like to know where the advice is coming from, and peppered with some hints you should pay attention to.

I would build my own if I want a custom designed canopy I couldn’t just buy. Building a copy of an off the shelf canopy will probably cost you more in the long run.

I'm liking the idea of vacu-forming over fiber glass. It's a lot easier to get multiple parts once you have the mold(s) made.

Of course, the shape and complexity of the part has a lot to say about how you go about making the part.

Currently working on some acrylic canopies,

420 plugs very neeeeeerly done.

One advantage to having your own mold is that you can pop out another boom and or canopy anytime yours gets macked and at very little cost, except you don't get the fancy original paint unless your good at that or know someone who is.

I figure a 700 plug and mold set for canopy and boom would be worth $1200, materials to make the set in fglass under $10 (one yard glass and 200ml resin) while cf and epoxy would quintuple the price. Then it has to be sanded and painted for $100 or so. That's only after you have the machinery to do all the work in each process or you cheap out and use brushes for gel, and rattle can paint.
