MZ ES250/2 Trophy Rebuild Part 2

Phil Speakman has down his MZ, ready to start it to glory — which lots of decisions. To shot sand blast or vapour What sort of finish to opt

And does copper really the devil in it…?

Once the down of my 1972 MZ ES250/2 was completed, it was time to outsource the In the past I have paint shot blasted, wire and re-sprayed and yes; even coated from home. But not any The last time I did any re-spraying and saw the of the garage afterwards I swore it be my last.

The filler and rubbed primer dust gets as does the overspray.

A couple of ago I bought two old Mindon powder machines for Ј90 and made one good one the two. However, I could cure the smaller components in my oven once they’d coated in gloss black and the frame and swinging arms had to be sent out to a professional. So in reality the in doing things like and various mounting brackets was quite minimal (maybe Ј60 or so per which to me is nothing compared to the it wrought within my garage, mind the colossal amount of it took me to a do a reasonably good

In fact, I’ve recently my shot blast cabinet on as I was fed up with it squaring up to me each I opened the door of my shed, the little anthropomorphised gloss red

‘Great’ I thought, ‘more again in my garage’ and there was for a or two until a Ј20 1950’s Smart and lathe took its place and to move, the nasty squatting anthropomorphised gloss blue

The frame, swinging arm, footrest bars and all the other fiddly bits were out on the floor of my powder coaters and before I left them in capable hands. I like to a visual record of everything given them to ensure I got it all again. Not that they ever let me down in the past, but always good to have a list to prevent head and conversations that start ‘are you sure you gave us blah blah blah’ on.

Later that same I returned to the house of my engine friend to receive the good All the internal components of my ES250’s were virtually like The piston still had the original marks on it and apart from one chip on one easily replaced wheel and the … crank all was well.

To receive the good wasn’t the only reason for though, I was there to pick up the crank cases, barrel, and engine covers for the full After all, if you go to the trouble of a strip down, you may as well get all the looking their best for re-assembly and besides, my friend had my crank rebuild to be getting on

My local metal finisher cheap, but I think his work is as as anybody’s out there. The head and were low pressure vapour to removed 33 years of corrosion, oil and salt damage, followed by over finishing in a barrel to achieve the ‘just left the fettling plant’ look. The and rear hubs also through the same process, for my friendly local wheel to set to work on.

Over a coffee we discussed the I required on my engine cases and the (carburettor cover) and as I didn’t them polished to a mirror he suggested another final mop finish instead. He showed me an of this finish which we would most closely the best of the three available factory finishes that available to the 1970’s discerning MZ Die cast, dull or factory

The same finish was agreed for the plates, but I wanted the wheel the handlebar levers and choke mirror polished, as in my eyes seem to look better way. These will all be blasted first to remove 30 worth of dings and scratches, but it is so less aggressive than blasting that can often an alloy component by eroding it saving within a couple of

He always likes working on MZ components as he reckons that to some Japanese and British their quality is far superior. The only seemed to know how to things one way in aluminium and that was His words, not mine.

I also left him a little bit of work too, but the DDR bikes big on chrome plating due to the cost of chromium from the far east. It occur naturally in the region and simply didn’t have the currency available to them to importing it just to be used as Although lacking in chromium, the rolling mineral rich hills are abundant in other such as aluminium, silver and

It was 18th century Saxony smelters who first discovered or ‘Kupfernickel’ which translates as with the devil in it’ as it like copper but was too hard to be malleable. It was this abundant ore that was the very reason for the DKW being situated there in the place.

I degreased the crank cases and they cleaned up very with degreaser, detergent and a bit of grease with a small brush. I was considering getting barrel scrubbed, but they so clean it really would been a waste of money.

So I just had to wait for the bits to running back to me…
