Cragsider Build
« on: April 27, 2013, 08:56:41 PM »

Hi all, I thought that I would start posting some photos on another build that I am working on at the moment. :-))
It has been a while since I did an update on my Amity build this is the reason. {-)
The scale of the Cragsider build is 1/24 this makes her 53:67ins long and the beam 15:84ins. I built the plug using the plank on frame method here are some photos.

The next two photos show the plug after a lot of preparation and then painted.

Nice one Brian - I've never seen a plug made that way before. By that, I mean with the frames cut in half and glued either side of the fore and aft keel. I've always assumed frames were "slotted" in place - hope that makes sense ? :-)

The plug was two pack painted DMW and then a mould was made from the plug to produce the fibre glass hull.
Hi Ray making the hull this way was a first time for  me to, it was a bit time consuming as I braced each frame and then glued.

Now that is one large beast...she looks amazing, some great engineering skills there. She is going to be pretty weighty once done, how are you going to transport her, trailer or van?

Thanks gents, Mark I think the total weight will be around 5 stone she takes about 4 stone to get her down to the water line.
Eddiesolo I have a hatchback and she fitted in no problem.

The outer tube that holds the nozzle was made from alloy and a brass tube fitted into the alloy to act as a sleeve for the nozzle shaft to fit into. The reason for fitting the brass tube is I find that the steel shaft sometimes reacts with the alloy.

Hi all here are two photos showing the way that the motor and bed plate are fitted, and two showing some of the deck frames.

Cheers Mark the rubber in between the motor and the bed plate allowed me to get the right tension on the drive belt.

After filling in between the deck frames with 10mm ply the deck was then covered with 2mm plastic card. I decided to us 1.5mm alloy plate on the stern; the reason for this was the Cragsider had a removable steel plate for access to the Kort head gear I decided to fit the same as it would be easier for repairs if anything happened to the Kort on the model.

It's no wonder, then, that I have difficulty lifting your model boats  <*<
 
Lovely work Brian - eagerly awaiting the next update  :-))

Hi Brian

I have really enjoyed looking at this and I like the belted motor method. Will the rubber stretch at all and need re tensioning?

Hi Dave, I have used this type of drive on a couple of builds and had no problems up to now, the toothed belts and pulleys are purchased  from MFA and are very good quality, I think it would take quite a lot to stretch the belts.
