No Title
Dear All
Need to make up a wedge in between surface drive and transom, as need to get the surface drop to bolt onto transom at 12 degrees
Therefore lower transom now 2 degrees, needs to be 12 degrees
the disc would be 200mm Dia tapering from top of 20mm down to 2mm over the 200mm Dia, or make the wedge disc slightly larger
The wedge would then need have inside approx. 100mm cut out with hole saw, 4 bolt holes
The wedge is not taking any stress as the surface drive load is bolted through transom just needs to be take the sandwished bolted pressure
1. add strips of fibreglass CSM, 25 oz biaxle to build up the thickness over the width of the lower transom which is 500mm wide, would need to be 20mm thick at lowest part
2. attempt to fll and shape with PB, however concerned with trying to fill gap 20mm thick
3. have machine shop machine up a aluminium wedge...note have the aluminium, cost approx. $300 to machine
4. make the wedge using Laminating casting epoxy west 105, as I have spare 3 litres, this would be epoxied onto Vyinyl ester transom, then corners filleted
5. Option 3 using Vinyl Ester, CS 6mm fibres, microspheres
Was thinking could cast the resin into a large plastic lid, angle the lid to achieve the desired basic shape and degree wedge, then drill out holes cut inside out
attached picture this is represented of the gap which need sot be filled
sorry picture is on angle, top is left hand side
cheers
