Trident: seat, forwards, pipes, lock, electric box, brake...

Post by Prof » Fri Jun 11, 2010 10:22 am

Rod brought in his partly built Trident to have the fabrication side finished. He will then pull it apart, repaint and get it wired up. when it is finished we'll feature it in Chops'nBobbers...

Here's the bike ready to be collected...

Seat has a slim horn style backrest that is beautifully supportive and comfortable, adds lots of class but doesn't take away form the overall lowslung stance of the bike.
Image

Stainless tank cover. It is bolted to a stainless bar that follows the tank top contour and then dips down to mount the ignition switch.

Bike as supplied, was 2.5" lower at the front and would have been quite dangerous to corner on. I made up 3" slugs our of stainless. Button head on top is in place of cap and is removed when replacing fork oil.
Image

Rear brake posed quite a challenge as the anchor and lever are uncomfortably close to the rigid frame set up. As we are running a cable rather than a brake rod, the neatest solution was to turn the brake plate upside down.

Because the axle plates are quite close together, they allowed only 20mm side movement for getting the wheel out. Slotted anchor works well and holds the brake firm while allowing axle adjustment. Sissy bar was shortened and mounted on top of the brake bracket with a matching bracket added to the opposite side as well.

Axle adjustment plate is made from stainless angle. Brake lever needed extensive mods. the brake cable adjusting knob was turned on the lathe form aluminium.
Image

Forward controls used parts Rod had collected. Brake and gear levers are made from HD gear levers. Forwards are mounted on new extended front engine mounts... a challenge in them selves as the person who raked the frame previously drilled his new frame holes very crooked!

Carbies are no longer supported by an air box, so a simple stainless hanger has been made that is supported by a tapb welded to the top frame tube (just hidden).
Image

Rear engine mounts are stainless and replace the massive originals. Tail pipes (turnouts) are stainless and have internal baffles that are held by the same bolt that holds the turnouts. Rest of exhaust system was built from preformed mandrel bends and straight pipe.

Battery box had to be narrow to fit with in the swing arm brackets which rod wanted to retain. It contains three coils, glass mat battery and a fuse box (forgot to get any pics). The rear cover bolt doubles as a battery bracket. Some quite tricky fabricating was involved in not only getting it all to fit but to be accessable on that dark rainy night! Horn actually sits upright and covers the swing arm bracket.
Image

Speedo mount is aluminium crved to match the top tree. End 20 mm was cut so it coud be bent and then welded. This strengthens the bracket so it wont crack along what would otherwise have been a straight bend. you can also see the roll pin that keeps bracket level and allowed the use of only one mounting bolt. Speedo rests in some foam rubber.
Image

Steering lock on this bike was awful. A simple solution was to cut away part of the existing stops, weld up the holes and give it a very nice lock.
Image
Image

this photo of the seat mount is a bit blurred. the seat is pushed down onto the frame and a knob on a bracket attached to the frame is tightened. Knob with its 8mm thread was off a small pipe cutter.

Nice work, sweet looking bike.

Just one thing, I noticed that the rear brake bracket has the slot offset, was this done on purpose?

Image

If it was done to have thicker material on the side of most load, wouldn't that be the left had side as when the brakes are applied the torque reaction would be in the counter clockwise direction.

I know I'm being a picky little person :roll:

It's just I like to look closely at your simple and elegant solutions.

Sorry to take so long to reply, but missed this post Hap.

Yes the force is applied to the thinner side. I can't remember the circumstances that resulted in the slot being offset. The tab is 10mm so quite strong enough.

All comments like this appreciated.
