So some more English Oak was sourced this time from Boutique Timbers a nice plank/board some 2m x 250mm x 55mm, always best to have more wood than you really need.
The idea was to store as neat and practical as possible the two different sized series of Bobbins six small, three larger.
Of course the need to use the whole lot at once would be rare well for some maybe, I envision that will not be the case for Sue however.
The design came to mind for a two tier with the top being able to rotate to allow access to the lower set, but ability to remove if need be.
I Turned up two platters, one 9" dia x 1" thick and one 7" dia x 3/4" thick, gave some shape to the top sides so the bobbins would sit a little high off the running area when they turn.
Marked out the top piece to be a tri-arm for the three larger bobbins with cut outs allowing access to the lower bobbins. This was cut using the scrollsaw and shaped and sanded.
I turned up a brass bush for the top section to rotate on and use of a lock pin to allow both to be one yet still rotate.
Machining the brass bush.
19mm inner dia, 22mm out dia. large face section 30mm. 2mm bearing area thickness.
Below the bush in place on the top section prior being cut to shape.. Three holes drilled for the bobbin supports which are 1/4" Gal rod.
Below dry fit up of the base plate and both in right photo.
Below the top platter now cut to shape and further dry fit. Left with Gal rods dry fitted and a Bobbin showing the height.
Below a view after final assembly.
Lock pin in place the top section rotates on the brass bush.
