well the trike's more or less finished now and to be honest i'm getting bored. so the poor little savage has gone under the axe,this just a basic mock up but is pretty much how i would like it to look. i've always fancied a bobber so here it is  scanner's bobber standard  scanner's bobber  scanner's bobber  scanner's bobber  scanner's bobber it's amazing how quickly they can be taken apart ,this took just a couple of hours .shame it takes so long to get them back together! this will hopefully be a little quick project,a few weeks maybe but that depends on getting the rear mudguard sorted this is the same one that looked so good on the front of the trike so i'm thinking of trying to take a mould from it and making a couple in fibreglass.any tips on making a mould would be most welcome as i've never done it before although i have a general idea ! |

Any progress on this ?
Sorry, but looks like we know nothing about making things from GRP on this site.

It will take a bit of work to use that as a plug for a mould.
You need to sand it down, fill any imperfections and have it as smooth as glass, this might mean a quick coat of paint.
Then give the outside about 3 coats of a non silicon wax polish.
Paint gel coat over this, out side only.
When dry, 2 coats of resin and f-glass matting.
Follow this by putting a 10 - 15mm rope around the mudguard about 25mm from the edge, and 2 more coats of f-glass over this. this will cause a bit of rigidity in the mould.
The mould can be trimmed when dry with a grinder, or just as each layer goes off with a sharp knife, but hard to hit this point.
Let it all set for a couple of days, and then flex the old guard out of the mould, it might take a lot of gentle prying with screwdrivers to release it.
Hopefully you now have a rigid mould, but I would add some steel to stop it twisting with the heat as the resin sets when making the new guard. Screw this into the area you glassed the rope into.
Make sure to use plenty of polish, otherwise it is hard to release the two parts when finished.
Does this all make sense, call me if not.

Hi Olds ,not done much more except for welding/repairing the rot in the guard ready for isoponing now.
yeh i get all that Alan, was much what i was going to do except i was going to use ply wood for a spine and strengtheners but my main concern is if the plug will pull or if i need to make a split mould,easy enough as long as i plan for it to be split in the middle and i still need to order some gel coat

and just another quick one ,the handle bar risers are rubber mounted but most after market ones are not so does it matter. i'm thinking of a 4" riser with the standard to give the effect of mini apes,the standard bars are 8" rise standard so 12" overall

The taller the bars the stiffer you will want the mounts. I have often replaced rubber mounts with solid. You may get some vibration but I doubt it will be much.

You'll only need to make a split mould if you curl around the edges which you don't need to do

well it's not working out as quick as i hoped but goodies have arrived and now i can get something done with this.  scanner's bobber got this on ebay,was going to make one but by the time i made a mould then took 2 mudguards from it it was going to work out expensive. now i want to mount this on the swinging arm to get a nice tight fit to the tire ,the mount on the swing arm is no problem but what to do at the rear. if i make rear supports as you would on a ridged it will look unbalanced because 1 side will have to clear the belt guard. could i mount 1 side to the belt guard and 1 to the axle spindle or the preferred option make an internal fish bone type spine to support it internally and invisibly,my only worry is that the welds might crack with the weight all sopported in 1 place and the vibes from the big single. opinions please  scanner's bobber i've gone for an led lamp which will be set into the seat where the pillion pad used to be |

no internet for the last couple of day but got a bit done at the weekend mounting the back mudguard first tried this  scanner's bobber nope too bouncy then this  scanner's bobber  scanner's bobber nope not happy with this either, the width of the belt pully makes it look lop sided so  scanner's bobber  scanner's bobber went with bending some 1/2 " box which is ridged enough to do the job and not too heavy. i still have to make a base to bolt to the brace in the swinging arm but that will be the easy bit. i'm going to bond the mudguard to the bracket so there will be no visable mounting  scanner's bobber |

cheers bikebuster was off on holiday today so got a bit done at the bike,everything seems to take twice as long as i think it should .oh well first i wanted to be sure the wheel is stright in the frame so knocked this up, a piece of timber with 4 screws protruding 3/4 of an in to clear obsticals,these touch both edges of the front pully then adjust the wheel until the rear pully is touching the 2 rear screws. job done i hope anone see anything wrong in this thinking?  scanner's bobber  scanner's bobber  scanner's bobber bolted on the bracket for the rear muddy and used double sided tape to hold it in place on the bracket while i removed the whole assembly and drilled the mounting holes  scanner's bobber  scanner's bobber (sorry their sidways !) then moved on to the panel under the seat which will hold the tail lamp first in card the 1 mm tin  scanner's bobber  scanner's bobber  scanner's bobber would like to have mounted the light but i've got a stinking cold and sorta lost the will to go any farther |
