MAICO Pre-60 Alloy Oval Barrel Blizzard Project.

[Mick D]

The cost of postage on that lum of cast iron out of euro would be more that the barrel cost

What about removing the broken top fin only with the head on be hard to pick

Pity it was not a Alloy barrel   

My DKW projects have been a pain in the arse postage wise out of Germany

What an awesome pic Thank you VMX60!
More proof that an all alloy 175 based engine is legal to race in Pre-60.

Your dead right, the barrel was 65euro and the shipping to here was 91euro

Good idea, I would have been satisfied to remove the top fin completely, but,,,,,,,,,,,,,,
a view from the left


Out of all the countries I have dealt with Germany has been the most frustrating. A lot to do with boggy translators, but also a lot of dodgy sellers that I will not trade with again.

Bloody hell hope the cast iron Maico finning is not like the Deek barrels Telves Finning


The process was pioneered by Alfred Telves of Frankfurt-am-Main in an endeavour to obtain more efficient heat dissipation, allowing higher engine speeds and greater power output.

This system was not exclusive to DKW but they were the ones who made most use of it on their production bikes. The process is based upon a centrifugal casting method, producing bi-metal cylinders consisting of thin staggered copper fins on a cast iron cylinder barrel. This was achieved as the centrifugal process threw the molten copper being the heavier metal into the extremities forming the fins, while the lighter molten grey iron formed in the centre area, creating the cylinder wall.

The advantage of this system was to produce a cylinder barrel which dissipated the heat more efficiently from the thin copper fins. The fins could be made shorter and closer together, which were staggered to increase the air flow efficiency. This would not be possible to achieve with cast iron alone and led many manufacturers to concentrate on aluminium from the sixties onwards for their production

Deek did make a Alloy barrel for the 250 one day i hope to find same

I stick welded the cast iron fins on my Triumph 500 barrel a few years ago but for the life of me can't recall what rods I used (possibly Austarc Supercast ). I don't know whether Maico cast iron is comparable to the Brit stuff but I had no problems and it dressed up nicely. Once painted you couldn't tell which fins had been repaired.

Hi Mick,
Like Mark, I've had success welding cast iron fins on a Triumph cylinder, but I used the tig with S/S wire. Preheat and postheat required, but easy to control,
Pete.

common as muck these old Maicos....

Can someone tell me how heavy are these maico, do they feel light.

[paul]

the one at my joint isn't that heavy/bout the same as a 74 maico

Mick, tried to contact you through PM for a email to send the pics...
Anyway, here they are.
Get back to me at olam then an @ and then husaberg.no








I took off the paint in the "knee-dent" to check the surface as I had planned to have that area plated.
Can't see any rust inside through the fillerhole.

The tank is very similar to my -66 Tempo, but when I got both next to each other they where quite different. Too bad, as Tempotanks go for well over 1000$

[Mick D]

Wow, I glad I am not restoring building a  '66 Tempo,
  nice bike but Ola,

PM sent, try to be gently

[ola_martin]

Tell me about it, I found this in a field as a bare frame and swing when I was 13 years old, have been collecting parts for 20 years and are almost done, no reproduction parts except grips cables and seatcover. Parts are very hard to find and pricey...

Seems like every guy with a bike interest, born around 1950, wanted one of these back then, so due to nostalgia the fetch up to 70 000 Norwegian Kroner, about 12000US$

[Mick D]

I bet ya there were times when you had wished you had never gone out in the field that day
