After building a custom bracket, the parking brake is finally installed. (pic coming soon) Here is what the final speed will be according to the gearing commander:  |

Nice parking brake. Not needed on a Internal combustion engined bike/trike with a transmission but is needed on a electric one. Suzuki Burgman scooters have Nissin calipers with built in parking brakes on the rear.

Suzuki Burgman scooters have Nissin calipers with built in parking brakes on the rear. Thanks. This one came from a 2006 Honda scooter. Why do you say you don't need a parking brake on a trike with a gas engien and a trany? my trike has a 3 speed transmision, even if it had an I.C.E I still wouldn't rely on Piston compression to keep it from rolling down hill. |

Not too many I.C.E. shifted bikes ever came with a parking brake. Pull in, drop it in 1st gear, shut bike off, throw sidestand down, dismount and walk away.

Early on I considered trying to come up with some form of parking brake, but as time passed and the trike never rolled off, I began to trust compression more and more. Can't say I ain't a little uneasy leaving it parked on a slope though.

So I got all excited and bought the pink home insulation at homedepo and I was able to easily shape it. Now I lay down the fiberglass and finito. However, the fiberglass resin melts the pink foam  I'm going to paint it with water base paint and hope that it will prevent the melting of the foam.if it doesn't work I'll get plywood and fiberglass the wood on the outside and paint the inside.

I think the blue foam will not melt. A lot of designers still use plaster or "Paper Mache" over chicken wire to get the basic shape, then lots of bees wax buffed in one coat at a time for like 8 layers. Then the release coats. I have done the paper mache forms and if you follow the age tested formula of the binder glue and add an anti-mold agent you can take as long as needed to work it all into shape. en.wikipedia.org/wiki/Papier-m%C3%A2ch%C3%A9 |

My goal was to create a moldless design where the foam will double as insulation for the trike.

I think if you use a different epoxy it won't melt the foam. I don't think it's as strong, but you're not building structural pieces. I'm no expert on this and have never built anything out of glass (yet), but I have done a lot of browsing of homebuilt aircraft sites.

Additionally, Pook has a thread over on the Locost forums where he preps the foam with a mixture of diluted epoxy or latex paint to keep it from melting.

So I finally got a chance to work on my project. So far I leaned that working with fiberglass is not as easy at it looks.and that I should put half of the hardner that I think I need. Other than that, it's coming along.  Attachment Deleted |

I see that you used the VW front end, where did you get the attach fittings? I looked at a couple of off road sites and found units that were for a brace however I am looking for the same ones that are on your project. Also what type of tubing did you use?
The acceleration must be pretty good!

Thanks Elanimal28!
I looked in ebay and nothing popped up...just was calling them the wrong thing...
The scheduled delivery for my front end is on tuesday and I am going to be back in country on thursday so I can go pick it up.I tried to order the clamps but ebay will not let me log in from a sanctioned country (Myanmar....the old Burma). I am also going to get another couple to mount the front end to my welding table.
Thanks again for the info!

I had a chance to do some work over the summer but unfortunately I got a new job as well. I found an autoglass shop that made me a custom windshield for $145.00  . I learned a few things working with the fiberglass resin and pink home insulation. For one, the pink homedepot foam works fine for fiber glass as long as you give it 2 coats of water base paint and you don't do a layer one day and the next layer a week later. What happens is that the fiberglass resin will heat up and the foam Will slowly shrink and/or warp causing your pice to deform. Number 2 if you don't work the resin in until it becomes transparent, the resin will only stick to the outer part of the cloth and when the foam shrinks it will separate from the foam. The end result is a lot of mountains and valleys. Just look at the side of trike. If you do at least 2 layers on the same day or even next day, you won't have a problem. Just look at the front of the trike. Sorry for the long-winded post but I'm hoping that someone will learn from my experience.  I also added a second on board charger. Now I have 2kw of charging power . I added some eyebrows and I think it makes all the difference on looks  Attachment DeletedIf I had stuck to my original plan of welding sheet metal for the side panels and do only the top in fiberglass, I would have been done a month ago. But hey, I'm learning. |

I'm beginning to see the silver at the end of the tunnel . Attachment DeletedI say temporarily because my new job is about 52 miles away round trip and originally my plan was to drive 8 miles round trip. The trike only has 8 kw of battery power and that's not enough for a 52 mile commute with lots of steep hills. so I'll have to spend another $2k in batteries and do a Hudiny to find space for the extra 200 pounds of battery. But I'll drive it around town in the mean time and see what shakes loose  . |
