In Topic: Working Air Bag Suspension

22 June 2012 - 01:39 PM

I have given this some thought also since I am working on a 40 ford that is lowered.

The idea I came up with but have not tried is to mold the airbags using silicone. The bags should be hollow with the bulge of the bag being thinner than the rest of the mold. Then I thought of running the lines from the bags to a small tank just as they would in real life.
I would then use a medical syringe connected to the tank to raise or lower the suspension.

Since the volume of air you would need to move the suspension up and down would be very small just the action of pushing the syringe plunger in and out should be enough to activate the suspension.

The problem I can see with this is the suspension (not the bags but the actual suspension) has to work with little or no resistance or the car will not go up or down very well.

After giving it some serious thought I decided not to do because I didn't think the effort would be worth it.

But that is the idea I was thinking of using.

I was not talking about artistic ability when I said that glue doesn't take any skill.
It takes plenty of skill to chop a car up and turn it into something else.

I was talking about the act of applying the material.

It isn't a matter of how much I abuse a model. It just makes a stronger joint and a stronger joint will last longer.

I still use glue and I am not cursing the glue gods...

@ crazyjim, I would love to come to see that but it is a pretty long drive from Michigan.

@ GrandpaMcGurk, By all means post anything you have on the topic. The more info the better.

I understand your rant. I have been in the racing sim community building 3d models. A very similar thing happens there but it is guys ripping off other peoples work and passing it off as theirs.

The only thing worse than that is someone correcting anothers spelling. (he said with a grin)

crazyjim, I would love to go to that and see how someone else does it. I started playing around with it when I was about 15, as a matter of fact the soldering iron I am using is the very same one I started with. It was actually my dads and everytime I used it he would yell at me and take it away... He finally got tired of taking it back...

Back in the mid 70's and I was working in body shops they came out with an actual plastic welder that used hot air in a small jet. I talked my manager into buying one and I took a class on how to use it. The technique of making the V came from that class. At the time cars were going plastic on us with inner fender wells, radiator shrouds and bumpers which are the first things to crack in an accident. We made our money over and over by welding up a crack rather than replace a part.

For anyone interested in this here is a cool video that shows how to use an actual plastic welder. I am doing exactly the same thing but with a soldering iron. They don't show him doing the other side of the bumper but the process is the same, grind out a V and melt in the plastic.
