savings can be made if you are willing to replace the cost with your time, sometimes you can do it yourself to save costs, my example is that I drew up the plans, and then built the model with a minimum of outlay, using materials at hand, ie recycling timber and cutting my own planks to make a plank on frame timber boat, rather than purchasing the materials ready made.recycling wooden ikea blinds to get lime planking, ok the surface stain needs to be sanded off, a minute per plank, but if you have the time and inclination you can make savings.
