There must be a hundred 72s being rebuilt on this forum alone. Let me see if I can make this one go too. I started the information back on this thread if you want to reference back.

As described before, this is what the bike looked like some 15 years ago when I first picked it up.



It had been at my Dad's and he and my brother had been collecting parts to make a racer out of it. They gave up after several years of it sitting apart and got it back to me recently.



So today I laid out all the parts. Here I am with my 3 1/2 yr old. Hopefully she won't be too much older by the time this thing is back together. Yes, that's a Bultaco cap, but I do have a Norton shirt on!

Also as mention in this thread, I hope to video most of the process. I did video the parts as they were laid out. I still have to decide how to edit it all together.

I'm still putting the list of major missing parts. Some of them will come from my brother's spares pile and some will need to be new. I'll mock it together and then when I'm satisfied I have all the parts, disassemble, refinished and rebuild for good.

Here's the "fun pile".

Nice stuff. I really like that brushed AL tank. Get " cyberlink power director " to edit video. Has some pretty good reviews.

I'll just use iMovie or Final Cut Express. They'll be fine.

The tank will get polished and clearcoated (I think).

That's some nice stuff, try to finish before your daughter gets her license so you can test drive it and shake it down for her.
I just got a bike back to roller status after I took it apart a couple of years ago and it is a nice feeling.

Get that sucker together, we'll get our wives and same-age daughters together, and I'll meet you with my Dunstall replica Combat, let's say......

BARBER'S IN OCTOBER!

Maybe if I worked on bikes for a living that might be feasible (ahem) , but as I sit at a desk most of the time it's going to be a challenge. If this thing is together and running by next summer I'll be glad.

I didn't say WHAT YEAR!!!

I had talked about building the bike up "dry" and then taking it apart and doing a final build. I think I'll change my mind. Originally it was because the bike was a wee bit of a basket (ok, several baskets) and that way I could tell what was missing. But as there are so many new parts, it doesn't really make any sense to fit the new parts and then take them all apart, especially things that shouldn't come apart (think bearings and bushings). So screw it, I'll refinsh the frame and just put the sucker together. How else am I going to make it to Canada?

Even after the powdercoating threads I think I'll end up powdercoating the frame. I emailed Dave Wedlake, he's restored some of the most beautiful bikes I've ever seen, and he powdercoats his frame. Needless to say, if it's good enough for him it's way more than good enough for me. And because he'll be doing it there is no worry about any problems.

I need a modified front engine mount for the MkIII isos. I could shorten the ones I have but my brother found the correct one in his pile. As soon as I get it I'll round up the parts and hopefully get them out to get coated.

There's still two dirt events coming up and those take up time and money. Then the long wet winter...

Good luck with your build, I hope it all goes together easliy for you.

May I suggest you have the frame checked for straightness before you have it painted. It'd be a shame not to.

Regards Graeme.

Old Britt's site has an excellent primer on powdercoating Norton chassis parts.

I'm in the "don't do it" camp on powdercoating cylinders, but the opposing camps seem to have equal numbers.

That Tank would look great in Yellow, to match the rest.
Take time to make good cover plates and screw in bolts to protect threads before you powder coat.
It is a bugger to clean off after.

I've read the Old Britts on powdercoating. It was brought up here once that the masking they recommend for the swingarm section of the cradle is excessive.



I think someone here powdercoated in a light color and there was this huge bare spot. With black they recommend painting it to keep the clearances.



I've powdercoated smaller parts myself and quite aware of the potential issues. If I don't get all the parts in this batch I'll powdercoat the little stuff myself.

Any suggestions on checking the frame?

Regarding excessive taping on the cradle at the swingrm mount, nobody would want to have the bush flange or o-ring bearing on powdercoat or paint. The cradle is milled to a tolerance there. But if you only remove the coating at the bearing area and you can get the swingarm to it, then the clearance is too much. Hence, you gotta remove it all. You can paint it up around it after it's installed if you like though. You can use rear iso shims to tighten up the side clearance if you need to. If you need miscellaneous doodads, let me know.
