Good idea to start with small stuff - infusion has a learning curve! I think you'll want a slow-ish hardener, but because viscosity is reduced as...
I too am confused about what is happening here - but it doesn't look terrible from the pictures. Were you using something thin and floppy to mold...
You mention shutting the pump down before the resin gels... this could be a big part of the problem. The biggest issue is vacuum integrity - you...
Epoxy would be ok as long as it is fully cured before you get near it with polyester or VE resin. You can definitely grind out the joints and...
Plexus (methacrylate adhesive) is great for stuff like that because it is tough and spans gaps well and is a nice viscosity for this kind of...
Did you mean 17' x 44'? You can buy vacuum bag in very large widths but for a one-off you may be better off seaming 10' bag together. The seams...
That's not that bad! I'm not sure how much area you have to cover but Scotchbrite is great for this kind of thing - it works best if you sand...
Peel ply is the best - ideally the plain nylon (often with red-stripes) kind wet out on top of the glass tight with a squeegee and rolled with a...
There are lots of ways! Some dagger boards are built with a mold only on one side so they get stacked up in stages with shear webs molded on...
I agree - you will probably have better results with the foam! It has less resin uptake and should be easier to deal with - and stronger. Are...
I agree on the mixing materials thing - probably best to avoid that... and no need really to skin coat an infused epoxy part. There's also no...
Hi Alan, Your drywall mesh has me both interested and concerned! Will you made a complete flat test panel of the whole laminate? It would be...
With big flat panels like that the core will make it much stiffer with less glass - and be easier to build. I don't see any problem with your...
I've never used one like that but if it is easy to clean then it might be ok - this stuff gels hard compared to normal paint and if you don't...
You should be fine glassing with epoxy - a 5:1 standard one should be fine. You're just building a big surf-board - so the issues will be denting...
Yes, a cup gun with a 2mm+ nozzle will work fine. You may need to thin the Duratec - they make a thinner that works great - and make sure to...
Generally with the boats I have seen and worked on (both carbon and glass) that are laminated with epoxy (wet, infused or pre-preg) the inside...
In theory you can infuse any combination of skins and core and if the details are right it will be ok. I agree that core and top skin in one...
Unless weight is a huge issue it is probably easier to use "double cut" or "contour cut core with scrim" if you have a mold and are doing...
I'm not sure what other parameters you have or how tight the fit in the trunk is, but I'd look at using a wood core/structure with some fiberglass...
