Broad Ambition - The Model

Recommended Posts

right third section work today. lots of pictures. first the part is overlaid over the pattern, then the inner spacing set using the finished side, he lines of the part are added, and then the waste side marked. the faces of the joints are cut using the bandsaw (careful of your fingers here) and a razor saw used to cut the shoulders, some of these are slanted to match the inside profile of the frame, then the parts are glued and clamped, once the glue has set, the chamfers are sanded in with the sander set to the correct angle. the fit is checked. then the finished part is compared to the patterns and its opposite number.

So today being a nice day, it was time to get into the workshop and process the windscreen further. Time to fit the hinges to the side pieces. hinges positioned, drilled through at 0.7mm, the hinge part opened out to 0.8mm, stainless steel pins fitted through and glued in place, finished product I am happy with.

it is at this point I admit to messing up - yes I forgot that the sides slope in, so made the frame edges vertical on the outside, after realising my error I had to figure how to resolve this, I need to cut some wood from the outside of the frame, at an angle, so to keep the frame width constant, a sliver has to be added inside, tonight those slivers have been measured up, cut and sanded to shape, and then fitted.

its not a great deal, but its got to be right, next to cut the slope off(once the glue is dry

tonight was the night to trim the windows, so rather than struggle the hinge pins were knocked out and the windows cut down and sanded.

so its now the turn of the mudweight winch, a couple weeks back at the boot fair I had picked up some radio control bits, amongst which were a couple of small motors with gearboxes, I decided to print some winch drums and see how they went.

after that it was a case of testing,  on 6v one motor was making about 60 rpm, the other about 8rpm, after taking a couple of gears out of the slower gearbox that too was up to about 60 rpm. 

I do now need to make a spacer for the gearbox that replaces the two gears I have removed

well you know I talked about those deck lights and how small they were at 1/12 scale, well after a long trip from china the led's have arrived, the wires are hair fine, the led's themselves are tiny. but stick them on a 3v supply and they shine out.
