actually I do a some automatic transmission work on the side. it was a 35 year profession with my own shop and now semi retired. I do some norton repair and all the way up to some heavy equipment repair for a friend. the side benefit is I get use of excavators and bulldozers on my property at no cost and I started digging the basement for our new house this week.

Jerry, it's great that you are starting this thread. You of all people have the best advantages of the forum!

As soon as I started looking at your "before" photos, my mind began to see the shiny paint & chrome. It's amazing.

It's gradually coming together. It's happening in phases. I am in no rush as I have my MK3, but this is getting exciting and expensive. My Frame is away being fixed (more about that later). Another frame was butchered to fix the one I am using. I should have it back next week.

I am going to use webcam from Jim (TNX Jim) and he is radiusing the lifters. I have a combat head, but will go with a standard and that's going to get sorted later after I win the lotto.

I had some damage at 3 bolt holes in the casings and I sent them to Matt to tig weld. While he had the cases he did the breather mod and added bearings for me and gave them the "cNw" treatment. Same kind of treatment on gearbox. I am very happy with the results- Just took some pics:

A quick update on my 71 rebuild. It's been a long time as so much needed doing. I decided it is not going to be anything like original.

I had to butcher 2 frames to fix one good. The original frame had conduit welded in the back of the loop, so cut that out and welded a loop in from another frame. I thought that the gearbox was not too bad when I first looked, but it was pretty much trashed except for the shell. Most internals are new now including all new bushes etc.

The crank is away being balanced and as soon as that is back the motor is ready to go together. I have the re-bore etc. Jim has the head and is fixing that up. I

I've been focusing on the front end. Got some Forks by Frank tubes and doing the conversion for better damping. I have a disc fork leg and a decent wheel. I am sticking with 19 inch rims on this bike. Not sure about the front brake yet.

I have all of my chroming back as well as powder coating. So I am finally ready to make it look like a bike. Exciting time :D

A couple of starting pics:

I think I will build it here:

VERY nice work area, plenty of light and some natural scenery, but with air conditioning.

The prepped parts look amazing (as they should!)

You should probably look into screwing some 4x4's into those table legs for extra support, as that frame's going to get heavy really soon. I'm sure the Mrs won't mind...

I thought I had better update my rebuild thread. I am gradually getting there. I had to wait ages for the crank. Picked it up last week so I can finally put the motor together. Here are some photos that speak for themselves. Taken March 6th 2016:

Looking very swanky!

I notice that you dont have a kill switch. I just got a Zeta switch, which is normally closed and will bolt right up to the Brembo m/c. I think it fits in nicely, much more so than the tacky EMGO ones.

That's pretty cool. Yes I need to get one. I am not sure what I am doing electrically yet.

I also need to find a similar button switch for my digital speedo so I can use the trip sensor on it. I regret not fitting that to my MK3 speedo and will probably add it.

Just started putting motor together today. Its going together very well.

Have you seen what Grant did on his Featherbed special?

grant-featherbed-special-t23108-210.html#p306511

It is a pretty comprehensive solution, and not cheap, but very very cool. Not sure if they have a programmable kill switch in their controller.

Those button switches are very cool. The double one is what I need. Thanks for letting me know about them,
