harky Posted July 15, 2003 Posted July 15, 2003 Having never cut fibreglass before what is the best method for cutting out a hole for the air filters.(bit scared of b*****king my bonnet). Also once you have succesfully cut out,is there a clever method of finishing the edges or is it just smoothed with wet and dry. Quote
jeff oakley Posted July 15, 2003 Posted July 15, 2003 I have just done this and yes it is scary. Try to get a clear idea of the cut required and then tape up every where. Drill a hole with a hole saw and then with a dremel or similar cut out more as necessary. Take your time mine took two evenings to work out and cut but is now superb( even if I say so myself). Mine is a black car so I just used rubber edging but if you look at steppenwolfs build site he shows how to finsh edges well. Quote
harky Posted July 15, 2003 Author Posted July 15, 2003 thanks for that.surprise surprise the one tool that i dont have is a dremmel but its probably worth buying anyway. Quote
catflap Posted July 15, 2003 Posted July 15, 2003 B&Q do one for 19 quid, with a set of comprehensive bits, i have been cuttin FG and carbon covered FG with my one and its superb the black cutting disks, cut through 10mm carbon/FG like butter Goggles and mask a must Quote
Nick M Posted July 15, 2003 Posted July 15, 2003 We found it easier to see what was needed by removing the nose cone and drawing on the inside of the bonnet to get an idea of where things were. Then refitted the nose-cone so the bonnet sat where it was supposed to and started off cutting a small hole and just expanded it as necessary. Goggles and mask a must Absolutely Incidentally, when it comes to Dremel type tools to open up holes, I found the sanding band things (the cylindrical ones on the little rubber attachment) to be really good because the cutting discs can be prone to shattering. A long, fine flat file is also nice to use to create long straight lines when finishing things off. Quote
harky Posted July 15, 2003 Author Posted July 15, 2003 b&q wins it then.sounds like i have my weekend project sorted out. thanks all Quote
Carl Posted July 15, 2003 Posted July 15, 2003 The edge is then nicely finshed of with a bit of Aeroscreen rubber strip (also hides a slightly dodgy finish to the bonnet if needed) Quote
hilux Posted July 16, 2003 Posted July 16, 2003 Dremel Make up/reverse as required a cardboard template for both curved ends and rule a line between for accuracy/symmetry 1)Dremel plasterboard cutter (like a drill but with cross hatching/knurling on shaft) This will allow very accurate cutting near to the line you want and gets lots of material out of the way very quickly with little dust. 2)Finish with little cylindrical sander to the line 3)Finish edges by hand using wet and dry and you end up with a highly polished edge that doesnt require trimming. NB: wear dust mask/goggles Quote
neilwillis Posted July 16, 2003 Posted July 16, 2003 Don't make the hole too tight round the air filters, cuz the engine rocks quite a bit. I did mine with about 1/8 inch clearance, and I have to open it up by about as much again soon. I'd leave about 1/4 inch clearance all round to start with, and see how that works. Quote
DarrenRav Posted July 16, 2003 Posted July 16, 2003 dremel do an attachment for cutting ceramic tiles this turns your dremel into a mini router, I found this to be ideal for cutting air filter holes. Quote
harky Posted July 16, 2003 Author Posted July 16, 2003 Good advertising for dremmel. Is there any comission involved here or is it really that good a tool................... cheers Harky Quote
Nick M Posted July 16, 2003 Posted July 16, 2003 Dremels are one of those things that, once you have one, you wonder how on earth you managed without one ! Quote
neilwillis Posted July 17, 2003 Posted July 17, 2003 Just like a Westfield really then Mines small and red too Quote
Nick M Posted July 17, 2003 Posted July 17, 2003 Mines small and red too You should go and see the doctor about that then.... Quote
