Just ordered some random stainless steel tubing bends. Hopefully enough to get the exhaust sorted.
I also found a good source of really inexpensive 10AN fittings for the various hoses – good old Chinabay !!
I’ve also done some searching on “oil pumps” on eBay and found loads of suitable pumps. Suitable in theory but I need to check physical sizes, rotation of drive, etc. But at least it looks doable.
My exhaust ( turbo ) flange is being made as we speak.
I need to finalise the design of the spacers etc. for fitting the wheels. Once that’s done I will get the chassis properly rolling, then it can go on the bike ramp.
