1930s flywheels
« on: 04 Oct 2021 at 09:27 »
Hi I'm after a bit of advice regarding flywheel finishes. I have somehow ended up with 5 flywheels from the 1930's two of which had chromed finishes, another 2 appear to be nickel plate and a fifth is too badly corroded to tell how it was finished. I am presently resurrecting a 1934  Model Z and would like to keep it as original as possible so would be happy to hear your feelings as to what would be the likely finish of the flywheel.

Regards
Chris

As far as I am aware, Chromium plating was not commonly available before 1930, so 1930's flywheels were most likely chrome plated, whilst pre 1930 flywheels would probably have been nickel plated.

Thanks Eddie I'm trying to get my model Z as close to the original as i possibly can but the flywheel that actually cam with my jigsaw puzzle was the very rusty one so wasn't sure.

I would agree what Eddie writes and can tell you on my 2 prewar Douglas bikes (H3 + S6) are original with chromium plated flywheels.

What a marvellous bike !

Not exactly bristling with chrome, is it.
Well understated.
Is the exhaust ?

Ron,

I had bought this bike dismantled and with ( "exploded" crankshaft) and only few engine parts. It was stored for decades, still in original paint.
The exaust system was also missing.
I have got an exaust of older model (EW). Would like to get the right H3 pipes / silencer, best in used condition.

Hi Michael,

Looks very mellow - beautiful. We were discussing the finish on these 1930-ish bikes https://www.douglasmotorcycles.net/index.php?topic=8870.0 - does your bike have a blue stripe between the gold and the black?

Re chrome and 1930, the transition was amazingly abrupt. In 1930, most bikes switched to chrome - at the very least the De Luxe models (cheaper BSAs in 1930 used nickel, for example). The nickel that was in use was Watts nickel, which had none of the brighteners that go into "modern" nickel so it went dull very quickly if it wasn't polished. From 1931, even with the depression biting, chrome was dominant.

Cheers

Leon

Leon,

I have noticed the discussion ofthe 1930-ishbikes, but Ihave thought it was specially for the S6. So I do not get in, because my S6 (I bought it restored) has a silver / blue colour petrol tank and not perfect to the original.

My H3has no blue stripe between black + gold.

The inlet pipes on the engine are already chromed. The bike has a low frame number: FA564.

Do you have noticed, the exaust is nickel plated and older.

Here are a couple of pics that might help. My first Z1 was Chromed and i just polished it up a little. But it may not be the original finish. The bike I got recently looks like it might have been nickle plated.
