Double cross Bow model.

This is the progress so far , I have had to go back and take one piece apart as it did not feel strong enough. Don't be fooled by the glue for plastic models in the image , most of the glues has been PVA for wood to wood and cyanoacrylate for metal to wood . 
I have zoomed in on the calipers in the thumb nail as this job would have been impossible without getting accurate measurements , on lengths widths and diameters of the various components . Still a long way to go.

I have my booster jab booked in for the middle of next week , so I now hope to get back to a more normal routine after that :-)
