Creating a fiberglass snowmobile trailer (aka - cutter)

Step 5 "If it didn't carry cargo it would just be silly" ( Making the lid open)

The hinge was put on the left hand (Driver's) side so that when properly parked the lid would open from the sidewalk side of the street. The reality then and now was people park on whatever side of the street doesn't have the "No Parking" signs up for plowing purposes, regardless of the direction they were driving.

Considering the typical building's door hinge pin, I used 3/8" rod to eliminate any worry of it ever bending or breaking. I also used stainless steel rod to eliminate any worry of the hinge rusting. The bearing on the end was capped off with grease in it, to supply grease to the hinge rod over the years. It would have been easier to remember to oil the hinge from time to time. Make sure any surface getting epoxy is properly degreased.

On the side that opens, the tops of the right shoulder and right rear haunch, each have a thick nylon spacer washer embedded in them. A straight edge was run from the axis of the hinge to the shims to align them with the direction the lid would be coming at them. Corresponding pins in the lid drop into them to keep vibration from shifting the lid as it moves down the road. Since it isn't expected to do a lot of bouncing, three pairs of magnets are embedded in the surfaces to hold the lid down rather than trying to fabricate a latch.
