If anybody wants to remove rust from rusty Lister parts, mix up a molasses / water mix and throw your rusty parts in. It really works !

I use a strong mix about 1 part molasses  to 4 parts water but 1 to 10 will work but its slower . Molasses is easy to buy from farm stores, its a stock feed supplement .

Is it possible to use a old automobile 12V generator as a starter generator? Modify something ?

I have a WW2 vintage 12V 300 Watt DC battery charging generator ( A chorehorse designed by Johnson of Canada in the 30's) ) , if the wet cell battery is charged enough, you press a button and the generator acts as a starter and turns the generator single cyl. engine over . It is an old idea it seems , nothing is new !

Maybe the cylinder block has been machined too many times eg it is too low

Looking at ebay, these meter relays are very expensive ..I wonder why ?  I paid 20 bucks

Been reading the manual on this. There are two light dependant transistors and a light inside the meter , the transistors are in series with the 120V AC relay coils in the control unit ( don't understand this because transistors need DC to operate ? Might be a bridge rectifier in there ) ) . The blue and red pointers allow light onto the transistors and switch them on or off as the case may be. The coil contacts will handle 5 Amps so can be used to switch other devices on/off

I am not sure about the 50 cycle side of things . There are two wire terminals on the back of the meter , I think this is where the 50 cycle is sampled . But how much 50 cycle Voltage is needed to deflect the pointer ?  Mike

The sticker on the meter says:

RTG  400 - 0 - 350 MV

Term.  RES, 1500 OHM

Excellent 

My Jkson 6/1 has about 30 seconds of running time on it 

West Canada ..have you heard of a book. " Three against the Wilderness"  by Eric Collier ?  Good read
