As for now, I'll stick with my rebuilt "simple" mag ;)

Today I did some machining again on my lathe and made the end pieces for the distance tubes of the front forks:






I then put them in place and filled up some oil.
Some other parts were made also, but all in all nothing much to show.
So long,
Andreas

I do have the caps, though I'm not sure if I'm going to use them. They might look too posh 8)

Today I finally started on the rear mudguard. Of course all perfectly professional and with the best material to start with ;D



Bash it!




Getting in shape:




Well, still a lot to do...




So long,
Andreas

Making progress! I always have a few minutes only for hammering, but small steps are better than none.
The skirt is deep and the shape is slowly showing:




And it's getting time to work on the details.
Before:




And after:




About one third is in acceptable condition now and you can see how it might turn out:




More to come...

Or else it's to match the hammer finish of that green paint!

You're right! I allso though of laeving it in a hammered finish, like some of the old competiotion motorcycles used to have. It might add to the overall appearance, just as it was made in the 60s.

Here's some more impressions, of how it might look like:






So long,

Like the Fred Flintstone centre stand.  ;D

The frame colour is spot on. Excellent. Following with interest.

Still working on the front mudguard. The surface is getting better and better:




Used a 1-1/2" pipe bend as an anvil:




I think I'll keep the hammered surface as it fits the purpose of the bike and the idea behind it. I looks like these old NSU and DKW racers of the 60s and goes perfectly with the hammer paint. 8)

Interesting article - Thanks! I first learned about the DKW 3's in Vic Willoughby's book 'the racing motorcycle' back in 1980.

Have a good Christmas with your family.

Christmas well spent, there was some time again to wield the hammer ;D
I have no clue how many thousand blows it took to get here and how many will still need to come, but it were a lot! So a good 5 hours more and the front mudguard was in a state I could live with. So I set it in place and marked the final shape to cut:




Now it already looks like a mudguard:






Now it only needs the edges folded and some final shaping.
Isn't this finish just gorgeous?




Ok, I guess it's not to everybody's taste, but I wouldn't want to change it for a baby butt smooth finish anymore!
So long,
Andreas

That is a superb job, the hand beaten finish is absolutely fine. Would you perhaps have made it to a slightly larger radius to allow  clearance for the tyre/tire? It is a very snug fit, even for a roadster.

Yes, it curled in a little during hammering, so I need to stretch it a bit again. But that's no big deal, I guess. ;D
