Sunshine State checking in

Hello all,

My name is Roger McCaslin. I’ve been involved with composites professionally for over thirty years, mostly in the marine industry. I’ve also built wind blades, industrial parts, and a few aviation items. I’m well versed in tooling, building over 400 plugs and molds over the years. I (well, really me and my guys) have used over five million pounds of composite materials in just about every process that is commonly available. I’m the hands-on type, not the sit-behind-the-desk-and-issue-orders-type, so if I give input on something, it is most likely that I’ve had direct experience with it. If I didn’t get my hands sticky with it, I’ll tell you that it is my opinion (or my guess, etc) based on experience.

Although I consider my experience pretty wide ranging, I still learn new things all the time. One of my life long mantras has been that I can learn something from everyone I meet. I consider discussion to be an opportunity to learn from others as well as share what I know, hence my participation in this and other forums. I know that I can sometimes write in a professorial tone but please feel free to interject your thoughts about my posts. I may vigorously defend my position but I will consider anything you may post and I’ll never take it personally if we disagree. Another mantra is - there is always more than one way to skin a cat. Nowhere is that more true than in composites.

The above is about as much self promotion as I’ve ever done and I think it’s more than enough. I’d rather you judge me based on my posts instead of some fluff that I could have paid someone to write.

Welcome Roger! Ever worked with AFP/ATL/FW? I mean that’s a lot of material to go threw just laying up by hand.

I made a slight miscalculation in my previous post. The total weight of material is more like 4 million lbs but I’ve been at it for over thirty years so 4 million lbs doesn’t seem like that much, at least when you look at it on a weekly or boat by boat basis. About 500 boats at an average of 8,000 lbs each. Somewhere betweem 25-30 employees running that material.

Not sure of the acronyms you posted but I have used most common methods - hand laid, spray up, infusion, wet bagged, RTM, VARTM, Lite RTM, etc. Even did some cosmetic repairs on SMC and BMC products.

What kinds boats?

AFP = Automated Fiber Placement
ATL = Automated Tape Laying.
FW = Filament winding

Welcome , we can’t have enough Floridian’s in here :slight_smile:

Do what you do if that’s what works best for you . The world would be boring if everyone did everything the same .

Hi Roger, welcome to the forum.

Sorry I didn’t answer these posts earlier. Kinda lost track. :slight_smile:

Started building racing sailboats back in 1981. Moved on to large open fisherman 31, 34, 39.

And I’m a native to boot! :smiley:

Thanks. Hope I’m worthy.
