Yep I am.
I made another prototype using a different method of production and it is quicker to produce and requires less faffing around.
I need to make a jig for the tubes that bolt to the engine as these need to be 100% accurate for it to be safe and for it to fit correctly.
Unfortunately DTR and half term have got in the way!
As for the engine and gearbox transport dollys they are made from scrap wood and some angle, I will take some photos and give the dimensions for them this afternoon.
The gearbox one should fit a Sprint box as well.
