Hi. This should help. it is a video made on board by a model maker. lots of detailed images on the net, I used Google search and had a trazillion hits!! Good luck with this one, I am completing the Billings kit, it is quite old and the wood used is quite poor, I recommend to anyone building her should replace the old wood cut out sheets. This was my first attempt at using a bow thruster, made it from some micro plumbing PVC pieces , waste brass and an old motor, it works great and I recommend it as a nice side project. Take care and have fun, should be great weather for a little Delaware pond fun!! see ya at the waters edge. Mark.

This is the one I built

Try Google Images there are some on there, but it depends what you are looking for though when I restored an old example of the Billing Boats kit they helped out. Sorry that this reply is late.
