I also have a PDF of composites and their stenght to weight ratios as well as diagrams of everything composites… If you want a copy, PM me an e-mail address I can send it to. It has to be a non-swaylocks e-mail because it is a large PDF… ill post sample pics of it
EDIT: Scratch PM’ing me… i found the web address again (thought i lost it)
Here it is: click on materieals then downloadable PDF on top right…
the first link is pretty interesting…I remember looking at this site a while back but looking at it now, theres alot of useful stuff there. If i didnt just order a whole box of rollers fro jowwoodworker I would prob get that 3" epoxy roller, rollers have gotten me the best wetouts thus far. Beats any brush hands down. I wonder how that aero mat stuff is, would be cool if you could substitute dcell or corecell with a layer or two.
Squeegee…
Ain’t what you use, it’s HOW you use it.
Maybe if you used a roller right you wouldn’t be still using a squeege…
i just use a bit of balsa wood
and slowly move it around
it just soaks in quite quickly
To get the best performance out of rollers, you need good hard rollers, and a good hard surface like a mould. If you are using spongy rollers to move resin around, particularly on foam, it’s a good way to quickly and evenly wet fabric before vacuuming.
But as far as a tight and accurate hand layup on foam, you can’t go past a squeegee.
Use both, in their place.
yea haha I dont use a roller for a hand lay up…I usually use it with balsa on a wet out table with the fabric on the balsa…Also works well if ur using HD foam and need to glue up…u can get a really light layer of epoxy on and then vaccum and set your rocker, works really well…
Not sure what you are trying to say…
Squeegee is simple, does a great job, easy to clean, super cheap.
Rollers work also, of course, but cleaning takes more time, if you forget, you toss some $$ away, and you can save it after setup.
Why do something more complicated that doesn’t do the job any better?
The rollers are disposable…And I think it does a better job…I dont use them for “traditional” boards but when Im making a sandwiche board. I’ved tried squeeges a bunch of times, as well as different brushes. I feel I can get the best wet out with a roller. I use a seperate table, or wetout table. I put a sheet of plastic down, then my precut and taped balsa wood or dcell, corecell, whatever, then I put the cloth over it cut to the same dimensions as whatever I’m laying up. then I use a roller to apply the epoxy. Also, I jsut thought of this…I don’t put the epoxy in a bucket but rather a plastic roller pan…So, Im not like submerging the roller to get the epoxy, I just roll it on…
