Nein_11 Posted 9April, 2014 Report Share Posted 9April, 2014 Hello all, An opportunity has arisen to grab a set of 2.7 rs style bumpers in fiberglass locally, which is what i was going for and would save me the hassle of purchasing overseas. So what the hell am I on here asking about?? Well, the downside is they are for a narrow body car and I have turbo flares, has anybody had any experience widening these bumpers? The fiber-glassing itself doesn't worry me as I have done some fiberglass work on boats in the past. What worries me is the amount of "flare" I will have to create to get everything to line up well. Anybody been that creative? Look forward to hearing opinions! Link to comment Share on other sites More sharing options...
Pauly Posted 9April, 2014 Report Share Posted 9April, 2014 You can get this foam you can carve out and glass over them to get to get it how you want. So you could do a chop and use foam to get the rest of the shape. glass over the foam and join it to the chopped piece. Then remove the foam i would guess.

Nein_11 Posted 9April, 2014 Author Report Share Posted 9April, 2014 That's the sort of response I was looking for! Ill look into that now. Thanks Pauly. Link to comment Share on other sites More sharing options...
Pauly Posted 9April, 2014 Report Share Posted 9April, 2014 No worries. You'd need to go to a specialist to get it. I mean it's a no brainer that you don't make the foam flush, but make it a few mm lower so when you glass it's not higher. Once you remove the foam you can just reinforce it from behind with more layers. Post progress pics, would love to see it! Link to comment Share on other sites More sharing options...
OZ930 Posted 9April, 2014 Report Share Posted 9April, 2014 Poly-eurethane foam can be purchased from a good insulation shop. It doesn't react with fibreglass like polystyrene. There is a finer grade for surf boards too. Thats how I did this. Enjoy Link to comment Share on other sites More sharing options...
OZ930 Posted 9April, 2014 Report Share Posted 9April, 2014 Cover the area you are going work on with contact to protect the paint. Make sure its a good 50mm wider than the area you are going to work on to protect the paint and body from unnecessary damage. I stuck polyurethane blocks onto the body with cellulose based plaster which is itself easy to work and easy to remove. Shape it with a rasp. I used a hacksaw blade, bastard file and a rasp. You can get it reasonably smooth. Seal over with the (same) plaster, sanding back to a smooth finish. Then use resin to seal the plaster, sand smooth (lots of sanding). Any indents will show up in the final product. When smooth, polish with release wax. You now have a plug. Coat with release agent. Gelcoat, then fibreglass over to create a mould. Now if you break it you can can make another…..or even sell a few to recoup some cash. Its a bit of a process, but rewarding……apart from the itching from the fibreglass Link to comment Share on other sites More sharing options...
Nein_11 Posted 9April, 2014 Author Report Share Posted 9April, 2014 OZ930, As much as molding and recreating it turns a little job into a big one (and a reasonably priced set of bumpers into expensive ones)... It could also mean the possibility of re creating the bars in other materials such as carbon fiber... Much to deliberate.. Link to comment Share on other sites More sharing options...
OZ930 Posted 9April, 2014 Report Share Posted 9April, 2014 I wasn't meaning do the whole bar, just the "adapter" piece to fit much like the piece that is made when fitting a 934 spoiler to a 930. Cheers Link to comment Share on other sites More sharing options...
Nein_11 Posted 9April, 2014 Author Report Share Posted 9April, 2014 Ahhh apologies I completely misunderstood, that would make a lot more sense and cut down on man hours substantially! Looks like these bars may have to be a go, my existing rear bar has Fiberglas sections adjoining to the flare so it may be a possibility to cut the section and use it to mock up.

Airhead Posted 9April, 2014 Report Share Posted 9April, 2014 Thats how I did this. One has to ask why? Link to comment Share on other sites More sharing options...
OZ930 Posted 9April, 2014 Report Share Posted 9April, 2014 One has to ask why? Back in the day of "I can't afford what I really want" so "tried to be creative" with no training and a lot of enthusiasm….and it was a challenge. Didn't finish up exactly as in the imagination but it was fun. ……and I learnt a lot. Link to comment Share on other sites More sharing options...

OZ930 Posted 27April, 2014 Report Share Posted 27April, 2014 This guy has different technique you could try. I hadn't thought of using gap filler to create parts http://news.distractify.com/people/amazing/sports-car/?v=1 Link to comment Share on other sites More sharing options...
