You might want some venting/draining ability, too. Nice carpentry skills, Noddy.

They're called Trembler coils apparently. The box itself should be watertight when it's finished, so hopefully no need for drains. I was wondering about heat though, having coils shut up in a box?

I wondered if it might need venting to prevent overheating, pressure or expansion.

Yeah, heat will be an issue I reckon. I want it watertight for all the electronics, so might have to skip the coil idea. Nice idea though.

If you can run the coils inside it will look like a brass era car coil...lol..

That is brilliant! I hadn't thought of that. Not sure they'll fit, but I love the idea. No lols required!

Christ. I love wood bit on motorcycle and automotive projects. Super nice!

Heh, I'm enjoying the making of them too, something really quite nice about working with wood.

Alright, guess the movie...

As for heat, the only component I'd be worried about is the Reg/Rec if you plan to install that in there. The M-Unit won't care. But, the M-Unit does want a good solid ground. Do you plan to line the box with some type of sheeting for installing the electric? A brass block perhaps to suck the heat away would be both relevant and productive  8)

I think it bears repeating; I'm really stoked you stuck around to build this bike and share it. Especially given all the BS you endured when first undertaking your project. Oddly, those same yokels haven't been by to commend your project or admit how they're words tasted going down. Perhaps they didn't have sufficient beer to wash down their own crow... >:(

Good on you for all of it! And its a hell of a project!

I used to run coils under the carbs, and the chopper guys ran them under the carbs and in a box.
 So you could run a coil box , and the other box.. I think brass strips and knobs on the side would look really good..

You know, now that I see it assembled a bit, I really like how the light wood grain stripes in the instrument backs goes with the copper color from the other parts, you've got a nice interplay of colors going on.

Absolutely. I love this part.

Nah, that'll be out in the wind somewhere (dunno where yet). I will keep investigating the coils in the box idea though, I really like it. Will probably depend mostly on room given I hadn't planned to have them in there.

Thanks mate, I appreciate that (and you other fellows who are being supportive). I have noticed certain folks are conspicuous by their absence. Still, a long way to go yet though, haven't "saved this poor bike from being destroyed" just yet...  ;)

Andrew, leaving aside the subjective opinions of whether the CB750 "deserves" this sort of treatment or not, I find your design aesthetics, artisan skills and innovative approaches both admirable and inspirational.
The last 33 pages of this build have been some of the most enjoyable I have come across on this forum and l look forward to the ongoing build leading up to the final product.

Personally, I don't think any mass produced, multi-flawed (by today's technical and engineering standards) 40+ year old motorcycle is all that sacred.

Having said that, I am also respectful of the people that pull off great restos, but at this point, give me a well done cafe'd or brat'd or chopper'd or trike'd or steampunk'd effort any day.

This is one of those threads that I love coming back to.  I'll echo cal's words that I'm pleased you stuck with it.
I love restorations and see them the beauty in them but I also love custom work on bikes and see the beauty in them as well.

Regardless of a person's taste, it isn't difficult to recognize when someone has talent and your pores are oozing with it.  Great attention to detail and it continues to show on the finished pieces.  Looking forward to seeing this bike out on the road someday.  Keep on keeping on!

Totally agree! Thanks Noddy for the inspiration and looking forward to seeing how this bike turns out and then to see it on the road.

Good luck!

Absolutely. There's plenty of room for both.

So, figured it was probably worth busting out the good camera for the final (well, for now) product:



Pretty happy with my little wood-working job! Next on the list is trying to get that oil tank all soldered up, I have a feeling that won't go quite as smoothly...

Some wood working finishes will not hold up long to uv exposure or will yellow or will simply flake away or degrade quickly.  Keep that in mind.

Ever thought about using stained glass adhesive copper tape on any of the parts.
A stained glass cover for one of FrankenFrankenstuff's points covers could be interesting with the right pattern.
Not sure how it would look but it could be interesting with points at night.

Yep, it'll eventually be varnished, same as the gauge backs:



About 14 coats (from memory) of Marine Spar varnish, so should be good for a bit of outside work.

I didn't know about that copper tape... not sure where I'd use it, but good to keep in mind, ta! Oh, and I've got a pamco ignition lined up, so no points.

Marine Spar Varnish is built for outdoor use so it is UV stable and fairly long lasting.

Nothing like the adage, Anything worth doing is worth overdoing.

American sentiment of no replacement for displacement.  If it is good with 150hp then it ought to be great with 200-300-400 or more...
