dchamp, thank you kindly for this great information, it really is much appreciated. I have been side tracked on the building of the 8x68S Mauser . Things in South Africa is going down hill, in Witbank , Mpumalanga where I live we have a total failure of municipality services , I had to re-direct my finances to invest in JO-JO tanks, water pressure pumps and I had to sink a bore hole since we are some times for a week or longer without water..when we do get water it is extremely poor quality , unsuitable to drink or use in my household.
I fitted a gas geyser, two 4500lt JO-JO water storage tanks, new gutters and gutter systems to harvest rain water.
Sinking the bore hole to 85 meters was an expensive exercise , but all this I had to do , I now need to invest in a solar geyser to switch off the municipality electrical geyser..the last step will be fitting a 10kva Hi-brid inverter with 3x 10kva Solar batteries and 14x 540 Watt solar panels..when this is completed I will probably have funds in the future to continue my build.
