The original idea was to replace the washer bottle tank and utilise the space, similar to most designs like RRP, and make a 2 in 1 tank for the 2T oil and also washer fluid.
Also its about a 3Litre tank

So far there has been 5 stages to the build and they are as follows:
Stage 1:
Simply put I made a cardboard box and came up with an original idea/sketch, and just developed that over time to work out what exactly I wanted, nothing too crazy complicated but something that will do the trick.
Stage 2:
The cardboard box got further developed including some caps and a few of the auxillary parts.
Stage 3:
Further development of the final cardboard box design.
Stage 4:
Manufacturing of the back plate and mounting Holes
Stage 5:
Oil tank folding and welding up.

The next things to come are to finish up the oil tank by adding a feed tube, and a dipstick for now and use it on my NC500 trip, and when I'm back I will be adding level sensors and a side glass too!
Once all of this has been finished I will be adding a second tank onto the front with a slightly more intricate design which will be used as a replacement washer bottle tank so that I can have 2 in 1.
I'm extremely pleased with how this has turned out so far and I can't wait to get the finished product!
