"Ps your not the guy who's experimenting at argonaut?" Hey, thanks for the advice compositepro! I will do the tapering advice ASAP because I need to enlarge my mold's inflation neck anyway. No I don't work for Argonaut - I sent them an email the other day actually, small world, haha. Ah Ok i watch argonaut with interest ,its interesting to i see them learning the processes as they go along ,its been fascinating to watch the smaller guys ask the questions then implement their interpretation of them, i wondered if you were an employee I have cad files of several big box frames that show this and in the past few weeks have had a fair few folks ask how they do the bladders and air inlets do you go on velocipede salon at all?

No I don't go on velocipede - first I'd heard of it actually. I can give you a quick background on myself - when still in essentially unconfident teenager mode I flunked out of college twice, once software engineering then mechanical engineering. I fell into software engineering for a living and ten years later I want to do mechanical engineering, lol. Whoooooops. I think if you mistook me for an employee I must be on the right track? I hope so. My most pressing hangup right now is making a tough, leak free, reusable bladder. I have the mold creation end of things more or less covered. I get prepreg at what appears to be a very fair price straight from Zoltek. The consolidation and compression bit is what I don't have down yet. (Is it just me or do the QUOTE tags on this forum not work intuitively?)

Hello
Well you have knowledge that we would all like to learn from.
Could you post some pictures and some how to descriptions?
I would really appreciate this. There is painfully little on the web on this technic.
Thanks again
Fred

Hi Drew I was wondering as Argonaut actually use a company called ICE for all their carbon knowledge,was wondering if they were moving away from them as there are a lot more folks asking questions online now regards Bladder molding and seeming not to have got as far as you have. I actually worked in the USA many years ago in the bicycle industry, back when composites were in their infancy ,but moved away from it when i got involved with a guy who was working for a big military aeroplane company in Burbank Turns out he got me a job back in good old England as he was quite high up in the F1 teams as far as composites engineering went and we kind of went from there, spending time in F1 Defence you kind of develop things which companies outside those industries then patent claiming its NEW but again the birth of my daughter has brought a career change hence we set up a bicycle consultancy and manufacturing company in the UK If you get stuck for anything drop me aline chief

Funny, your words on the "claiming its NEW" end of things... I was involved in helping prototype someone's invention 10 years ago, and it is just now seeing fruition now that the patent has expired, and I won't ever see a penny. I think certain types of marketing people get reincarnated as dung beetles. Oh well, it was/is a good product. It'll help people. I'll send you a message soon - and to anyone else as soon as I succeed with a bladder sans a specialized factory (have you seen what goes into large latex dip outfits, yikes), I'll post up about it.

IME ive seen a fair few go down with an idea when a big company has steamrollered them ,morally its not right but hey what can you do I worked with a guy who made robotic arms, well he made the prosthetic sheath fro the arms hairs wars and all IIrc they were all one offs for each amputee and dipped latex, nothing fancy ,production ones came along with an entire factory i think it got to the US insurance companies and by the time each member of the chain had their cut it was 50k which made it only available to those with insurance and no arms not those who could scrape together the money. sad but it put me off corporate life for life did you try to reexpand expand polystyrene beads giving you a core dip it takes no time at all or alternately use PU that will last around 100 pulls from a tool i cant remember as im writing this if you mentioned it previously

IME = In My Experience? Yeah I know what you mean - funny thing, I had some guys do some handy man work to install an attic ladder because I was just post-op on my shoulder. Small world, one of the dudes was Arthur Fry, doing handy work for fun. And man I have never seen anything carpentry related get installed so well or so quickly. I do have some expandable polystyrene beads on hand - I'm only using a kitchen oven so the temperature is inconsistent, some beads would poof up to full volume others would not. EDIT - Before you ask it is a "garage only" kitchen oven, electric guts, no gas, I will not use it for food ever  PU = Polyurethane? Can that be dipped? Is Plasti Dip kinda along those lines? Haven't read the technical data on that product.

IME yep In my experience Plasti dip is like a coating over here in the UK for putting nice patterns on things, gets floated on water then you push the part through ,i wouldn't envisage it making a bladder When im in work tomorrow i will dig out the maker of the PU ,it might be classed PUR stateside we certainly dip and rotationally mold it to make even thickness bladders

Wow that stuff is CHEAP, half the cost of latex! And available locally. I'll play around with it. EDIT - oh you would not, didn't see the "wouldn't" - I'll wait for your answer on the PU stuff.
