Hello all,
I have lost count of how many coats of resin and sanding back I have done on this master hull. 10-15. But slowly I think I am getting closer to the right shape.I have had to look at the towed sonar array housing and have turned to getting that onto the port side of the hull. This is essential if I am going to mould the housing into the top hull which I intend to do. This has to be done reasonably soon so that I can work out how the mould will relate to the positioning of the port side stern hydroplane. I will be designing this plane to integrate with the base of the housing. So two moulds will need to be created for the stern planes, one port and one starboard, the port one being slightly different as it will have the housing coming out the end.
My original rear planes are swept in the trailing edge, The biggest misconception of the R class. they were never swept. Si I have got some scrap pine from the workshop at school and sanded them down to size. They are rough but in these photos show the general placement. I will also need to adjust the top vertical fin, it's a bit too high and will need to be reduced however I think the back end in these pics is certainly looking rather lafeyette class.
So I'm now spending time trying to develop drawings of deck arrangement and also re-coating the hull and sanding back, re coating and sanding back until the profile is as good as I think it's going to get then smooth it down to a glassy finish and started scribing the lines.
I looked into getting hold of some Renshape. I found a supplier down in Sydney. Asked for a quote. Sent me back one within the hour for a block 1mx1m by100mm $380!!! O.K, I guess pine is looking rather good right now...
