I am thinking about building some fiberglass covered foam skirts to dress up the area around the back wheels of my crown.I would like some advice from those of you who have worked with these materials before. 1.)How do you drill a precision hole in foam? 2.)Will the fiberglass resin react with the foam?I am thinking of using foundation insulation, 2 inch and cover it with fiberglass any info will be appreciated greately | ||

Test the foam first. If you use epoxy resin instead of polyester it will work with most foams. | ||

If you want to make something and DONT want the foam later Coat the foam with Epoxy as suggested , then lay up with cheaper polyester. To get rid of the foam , old battery acid works great. Before doing any laminating read enough to know what a "steel roller" (ususlly made from aluminum tho) is and how to use it. My favorite method is to get a 7 inch roller frame and take 9 inch roller covers and hacksaw them into 3 inch rollers. Works great to wet out and add resin in controlled amounts to the laminate. So far I have probably hand laid up a box car full of 55g drums in boatbuilding. Be aware there are 2 styles of resin.laminating resin is for for layup. There should be less than 24 hours and no rain , and you can continue with out sanding. Over 24 , sand 85% so you can see fresh surface. The other resin is finishing resin , that has wax mixed in. This WILL surface harden (the laminating will NOT fully ) but to paint , or add layers full sanding to get rid of the wax is required. Should ONLY be used on last top coat. FAST FRED | ||

There are 2 main families of foam and fiberglass resin. This is how it works. There is urethane foam and styrene (styro)foam. polyester resin, and "Epoxy" resin. The most common and cheapestis the polyester and this resin will disolve styrene (as it is thined with liquid styrene) Use urethane foam to lay up over with polyester resin. I would not recomend "epoxy" resin for such a project, as the cost is so much higher, and the strength would be of no advantage. Also "Epoxy" is more difficult to work with (it will not wet out the fibers easily) and takes much longer to set up. Styrene foam is used under "epoxy" lay-ups as there are no solvents in it to disolve the foam. Drilling foam is best done with a hole saw (urethane drills way better that styro), and larger ones by a knife on a homemade compas. Cold working the foam is best, as "hot knife" shaping will produce very toxic fumes. Shape it with a long sanding (17") board with 36 or 50 grit paper All the best | ||

that last guy gave some pretty good advice...I will only add,GO to harber frieght,get 100 rubber gloves for 6.oo & 1 box of 1" paint brushes for 9.95(sometimes on sale for 5.95)...before you mix resin...put on those gloves....usually ,ya' work with 10 minutes of resin...when you are thru, throw those gloves away & get some more for the next batch...same thing with the 1" paint brush | ||

you could take this one step farther,by makeing a reverse mold & use mold release....this way you'd probably have your own business in a year,cause you can make one after another,in the same mold,make me a skirt that covers both tandem axels,that looks like "mercruiser skirts" for my Eagle...& I will be knocking on your door | ||

The gloves need to be nitrile (blue). Latex breaks down fairly quickly with resins. | ||

Thanks guys, I think a little more info is in order. What Im going to do is shape the skirt with the foam ands than cover ti with the fiberglass. The foam will stay in place to give the skirt body. I am familiar with the process by witch you make a cast and than lay in the fiberglass but than there is a big void under thew thin layer of fiberglass. I only intend to make two of these one for each side and i need to drill 3/8 holes in which i will install the fasteners which will be embeddede in the fiberglass itself. the holes will have a sleeve to stop the skirt from being crushed when i tighten the fastener 3/8 o.d and perhaps 1/4 i.d.will be the hollow sleeve. thanks for the feedback | ||

Hey Doug can you also make me two fake warp engine nacelles about 12 feet long for the top rear of my '74 Crown 10-wheeler? I would prefer "early era" nacelle design. Vin 37317 NCC Warp Angel. CROWNS FOREVER  | ||

To make a precice hole in foam, auger the foam away in the area where you want the hole to be. A 90'bent nail in a cordless drill works well. Fill the void with epoxy or glue or about anything that is stronger than the foam and which will not react with it. After the plug is solid, drill the hole. | ||

Well, dogs.......you might be surprised. On a good day, we'll put ours up against any vintage coach. On a bad day....against any GMC, Flix and a variety of others. Take a look see....... www.dustyfoot.com/busnuts/ RCBishop.jpg, courtesy Scott Whitney. RCB | ||

Talking about gloves a couple post's ago, put on more than one pair of gloves. Then when one set is all gooped up, just peel them off and there is a new/clean pair. Dale |
