Re: building a frame for a Twin Cam A...

This CB750 rear guard gives the look he wants... http://www.choppersaustralia.com/PictureLibrary7/CAFDiggensRearGuard-00.jpg A new flat guard with a rear lip comes out of sto...

Re: building a frame for a Twin Cam A...

Sissy Bar... Garry and I played around with a few designs for a simple sissy bar. He liked a plain round top, but I suggested it be narrowed so the whole thing didn't look so wide. He was happy with this and we drew it up on a piece of particle board. I have made a number of formers over the years ...

Re: building a frame for a Twin Cam A...

Seat Mounting... Rear seat mount is also the rear guard support and ties the two rear frame tubes together, so needs to be reasonably substantial. Step one is to ensure it is square. This is done by measuring from a common point which in this case is a centre marked on the backbone ready to drill a...

Re: building a frame for a Twin Cam A...

Re: building a frame for a Twin Cam A...

Doing the final post on electrics box right now... Now for the sides. I will suggest that Garry have these chromed. So extra care is needed to keep them with out ripples that would show up once they are shiny. Once again the two sides are made from 2mm sheet steel. Here cut to basic size and rolled ...

Re: building a frame for a Twin Cam A...

Left side of battery box needs a floor. It will be supported by a welded in back. Swing arm is raised to its highest position so we can be sure the belt will clear. Always allow for the fact that the belt or chain describes a slight arc when it is under power. Here the back has been bent out of some...

Re: building a frame for a Twin Cam A...

Mounting electrics... With Garry 's approval I am building a traditional chopper style electrics box to house the battery and electrical components. Mounting the battery is a bit of a challenge due to its bulk. Unlike Harley, I will have the two terminals to the out side. Battery will also mount on...

Re: Long term Triumph Chopper project

Yes. That means that in SA you could get away with about 2.5" which is not very safe on a Motorcycle unless its a drag bike and doesn't go around corners!

Re: Long term Triumph Chopper project

I believe the ADR on motorcycle height has changed. In SA, now, if bottom of bike clears with both tyres flat it is legal. Might pay to check.

Re: building a frame for a Twin Cam A...

A gusset behind the steering head and a structural member under the seat left to do. I asked the engineer if he wanted me to run a tube from the bottom of the steering head back to the middle of the backbone or if he would accept a pair of triangular gussets. He was happy with the latter. the gusset...

Bit longer than the standard Triumph. How much did you add into the rear end and what is the ground clearance?

Front end is a 2" over Meatballs springer (from Bendigo, Vic) so we first need to knock up a set of risers. Handlebars...

Re: building a frame for a Twin Cam A...

Engine mounts... Front engine mount is next. Remembering this is a rubber mounted motor, this front mount needs to be substantial. A measure up of the stock mount provides a guide for this one... as usual, we will go a bit stronger. I have to make a new frame mount on the jig as the existing one ge...
