1937 Velocette 350 MAC

Unread post by triumph5ta » Mon Apr 02, 2012 5:14 pm

Or rather, the rotting remains of one...
Frame, Forks, engine , gearbox are sort of OK
Wheels are probably scrap.
Oh, and the frame is bent! What fun awaits!
Tank and oil tank paint was done recently to a so-so standard
few other bits of ironmongery.
It is currently tucked away at the back of my lockup so as not to distract me from finishing the Triumph...

I have one. Problem is everything I have taken apart is shagged, thought I was on the final stretch
last summer, however I pulled the front end off and today I made the bushes for it!

These were not bushed originally.
You can see the glint of bronze in the hole the indicator is in, the git who had them before me bushed the
lower holes, but bushed them offset! I am indicating to see if I can bore them inline or if I will have to offset
the hole rather than bore it lot's.

Good luck with all that then. If anyone can bring it back to life I'm sure you can.

I'm like my regular ride, old battered and bit leaky, but still going.

Acquired this spare engine. Crankcase number says its an early MAC 350
But it is not what it seems, it has a MOV 250 crank giving a stroke of 68mm and an MSS barrel giving a bore of 81mm.
This means a short stroke motor of just over 350cc ( I make it 350.4)
Also it has straight cut timing gears and a rev counter take off machined neatly into the timing cover.
Some kind of competition motor then?

Walloped the crankcase slowly apart.
There MAY be a small amount of corrosion inside...

Sucess!

A quick polish up is all that is needed....
