    Walther Type XVllB

    Post  ajg141 on Tue Nov 22, 2011 11:22 pm

    I have recently acquired from a friend a fibreglass hull for the Type XVllB. The length of the bare hull is 82 cm and the height 11cm minus conning tower. Quite apart from the slimness of the early Walther’s my first problem is how to remove the fibreglass flange shown in the photos. The hull is in 2 horizontal halves as can be seen and these need to be joined before cutting the access cover. The sparse instructions suggest using a rasp to remove the excess flange but doing this by sanding the 4mm flange away horizontally so that you end up with 2 flush halves that can fit neatly together.
    Can anyone suggest an easy way of doing this please?
    Suggestions would be appreciated bearing in mind my aversion to fibreglass dust and lack of a vast belt sander!

    Andrew

    Two easy ways,angle grinder with a 40 grit disc need a steady hand for this allso very dusty,second way sanding block with 80 grit production paper,hold the block parallel to the hull and just keep sanding after a time the flash will become very thin when it does snap it off.

    Thanks for those ideas Nigel. I think I'll give the sanding block suggestion a try. It certainly sounds a more suitable method bearing in mind my shaky hands - and my lack of an angle grinder!

    Some minor progress - it's awfully cold in the garage! The 2 halves of the hull are now sanded down (courtesy of a friendly coachbuilder) and have been taped together. The hull holes are being opened out and some filling sanding has started on the conning tower. 2 ply bulkheads have been made and an inner deck with 2 access hatches. The rear bulkhead has been drilled to take the MMB motor mount and shaft. The control rod seals need to be positioned next. The hull halves are still to be glassed together and this will need to be done before the glassed bulkheads etc are fitted as I need to ensure the propshaft lines up properly. There is very little room to work inside the wtc as you can see from the photograph. The total width is under 2" and the boat's overall length is 35". Progress is slow!

    Now almost finished. Some tank testing to be done now before venturing to the pond.
