img_0172.jpgimg_0141.jpgHello, I have recently joined a Men in Sheds group at the Wind Energy Museum in N Norfolk and we are restoring old associated machinery amongst which is a Bamford hit & miss stationary engine which has not run for 8 or 9 years. I have checked it over and the compression is good but the name plate is missing so we can't identify the model, can anyone help? I have posted photo's in my album. I have looked at several pictures on the computer and there are very similar engines but the magneto is in a different place. Any help would be greatly appreciated.

It certainly looks like an odd-ball.

It appears that most of their hit-and-miss engines used an EK trip magneto, while this one has an unnecessary and regular spark every revolution (the crank and magneto sprockets appear to be the same size).

Question might be why run the magneto at twice the necessary speed, although it may not have produced such a powerful spark at slow speed?

Furthermore, the magneto is driven by a duplex chain - unusual to fit such a heavy duty chain for such a light duty.

The magneto type may be able to be traced for age, etc - it looks like a quite late model for the hit and miss era.

Just some ideas for you to follow up. I’m not an expert on hit and miss engines at all.

Pat,

I've sent an email to a mate who collects Bamfords.

Swaffham, presumably?

Would have expected the Mag to be gear drive. Most engines of that type seem to be, so maybe a "field fix"?

The WaterWorks Museum in Hereford run a Bamford engine, which seems similar to this one. If you can provide some details, they may be able to help

Hopefully Martin's pal will come up with something definitive, but if all else fails, try contactiTWWM. The volunteers are only in on Tuesdays, so don't expect an immediate response

Pat,
Below is the answer from my friend. he refers to points being replaced with a spark plug, the points would be inside the head and when they were opened would produce a spark to ignite the fuel. dated 1920's, this link would show you how it would have originally looked, https://www.google.com/search?q=bamford+tulip+top+engine&tbm=isch&source=univ&sa=X&ved=2ahUKEwjJk-umu5PgAhUnRxUIHX02BVgQsAR6BAgEEAE&biw=1366&bih=664
Martin,
It is a Bamford Tulip Top 2.1/2HP and should be fitted with a Websters low tension system. The trip arm has been removed and the websters mag and low tension points system removed and replaced with a plate and spark plug. All home designed.
Regards
Andy

Thank you for the above very helpful information, the museum is at Repps with Bastwick about 10 miles north of Great Yarmouth. I spent many years working on Londons buses and thought that I knew about engines but it seems I have a lot more to learn. All help is appreciated. Regards Pat
