Having the choice of 3 icebreakers models to build. I settled for the above. She is now is service at Chile. Building to a scale of 1:100 the model is 89.8 cm in length and 20 cm wide. The plan was drawn by Jim Pottinger (hope I've spelt his name right) and was an article in Marine Model Magazine December 2010. of Tom Gorman's model build. Also with the plan came a 2 part build copy of the article in MMM Pictures to follow as just browsing over plan. The last picture is her in Chilean colours

Not much happening never thought retirement would be so busy A few pictures to get started with the first picture is the 2 part article of the build which came with the plan. Next is the plan blown up to 1:100. Next the frames flipped and photo copied to give 10 full frame to cut out. Attempting to get as many frames on to the ply saves on wood. Glue on to the ply and being cut to a workable size. All cut up didn't think I saved as much wood as I thought. Next I always keep a spare set comes in handy. With the dremel trimming off the edges to the edge of the paper. This build will contain a blow by blow of the build and mistakes included.

The first picture is the old frames which I shrunk in size to allow for thick frames and the tissue and resin. They were too small. Didn't realise all four sides would be shrunk and not near the deck height on the plan. Next picture. Rather than copy and paste them again, I did a print out from plan for each frame them folded the paper over and trimmed it to the shape giving a correct profile. Next picture is all forward frames trimmed ready for gluing to the ply. Next picture that looks like a correct size frame. Next the 1st keel was cut out and some of the slots cut out. This is what drew my attention to the frames being too small. The box of the wrong frames I'll use them in the future as there good quality. TMO new keel no2 with a modification and the building board

As I have said I built another Keel a bit more bigger in height with an added piece of wood in the turn of the up at the bow. Here is picture of the building board stages Notice I have put a few coats of varnish around the edges of the board to stop chipping/ splintering. The last picture of the building board is when the centre line and frame lines are marked up. Also closely looking at this board you'll se I have penciled in the motor/coupling and shaft Next picture I'll show the beefed up keel

The first four pictures are the keel modified to the support frame 9, 9 1/2.Will strengthen this area with some resin mat. I won't be fitting frame 10. Hopefully I will be using balsa or some other wood to fill and shape this area. Like wise the stern which I increased the ply width just before the rudder. The next two pictures are all the frames penciled up for removing their centres

Here is an update of the centres cut out of the frames and offered up to the keel. Still have to mark up and cut out stringers slots. Off on a little break.

Tricky one this for me. See the pictures Its the stringers they have at least 3 angles to fit in their right position. Kind of stumped how to tackle this problem.
Angel 1 flush with side of frame
Angel 2 flush with top of frame the deck
Angel 3 the cut for the turn on the bow and stern
The frames that have straight edges are an easy square cut as there are 4/5 amidships. ( last picture )

Working on the frames all cut out and mounted on to the building board. Quite a lot to learn here. Offered the keel on the frames half way thro I think the keel has a little bend. Things might need a wee tweak here an there. First picture is drilling the holes for the mounting. Picture two I didn't leave enough room on the edge of the building board to get a clamp to catch on so the tape did the trick Picture 3 some frames on their supporting block. Problems here as I don't think they were square. last two picture all frames mounted on board. Didn't twig the forward deck is lower than the rear deck and I had to modify the height on the frames 6,7,8 I'll investigate the keel tmo.

Fitted the keel yesterday few tweaks here an there. Just discovered the front of the keel wasn't trimmed off at the right height see picture one. Other pictures show a little problem with frame 9 second one from the bow. Seems too high to me ??
3rd and 4 frame near enough at the right height see the pencil mark on the frame.

If you look at Tom's keel and frames you see that frame 8 is slightly down from the keel. All the rest are up to the top of keel ( X s). Also the piece of steel for helping brake up the ice isn't on the keel like mine. I am going to cut frame 8 higher so there is a slight camber down to frame 9 or equal. The next picture shows the frame is miss cut. I am now in future going to trace using tracing paper from the original plan. Using a printer and cheap photo coping paper then gluing it to the wood it either shrinks or expands. I'll cut a cardboard template offering it up before I cut the wooden frame 8. Tracing paper on plan to trace frame 8. Hmmm how do you transfer the traced frame on the tracing paper to the wood. hopefully its not carbon paper.
