So when are you going to start making Bio diesel as you committed to last Jan.
or was this just more Codswallop.
We aere waiting for the results
Yes I am saying the failiure was due to the expanding ropes.
I have seen enough snapped bolts in my time to know the difference. They look exactly like a bolt that has snapped from over tightening or stretching.
Sideways forces would not have acted there as the bolt was in a hole over 1" deep and was glassed in - I had to unscrew them all the way out.
As to the biodiesel I gave up on it when the price of cooking oil hit £1.20 a litre - diesel is £1.19 at the moment. Used oil is pretty hard to get as that sells for over £0.45 a litre now.
I have a great solution now - I run on 30% neat used cooking oil - and I get contaminated diesel cheap - stuff that has been drained from tanks where people have stuck in a bit of petrol as well. The 30% oil takes care of any lube problems the petrol may cause. It saves me about £50 a week on fuel costs.
