started making the funnel and engine room structure from 1.5mm card, I  traced all the parts needed then cut out with sharp knife fixing together with super glue you can see the type I use £2.49 from local hardware


.




where I cut out  L and R  was wrong so filled in with same pieces I cut out
you will also notice I put it the wrong way round so had to re trace again  clown 



cut outs now filled Embarassed
I bought some gorilla glue last year, but i have not used it yet as one part has to be moist, so prefer my super glue 2thumbsup   






I have used 1.5mm card for all of this build



this is where I made my mistake forgot to cut out the part that fits to cabin. so I reshaped it and turned out ok



the funnel is made from sterredent tube, for (the younger people you get these for your false teeth to clean them  What a Face )
the funnel also is cut in half  I will do all the hinge later and show how I do it




there is also a frame to make for it to rest on



this is it so far

today I have been fabricating my own motor mounts, I used some old sheet metal of an old boiler front. I cut out the shape from a previous mount I made then drilled the holes.



this is the pattern from another mount I made



this is the drilled and bent to shape motor mount



before motors are fitted



motor now fitted



I have now fixed them to the mounts with 3mm bolts cut down to size from my stock.
These motors will work from 6v to 12v. I bought them of ebay years ago for about  £5.00 for 4,  thinking they were r380 but found on 6v they are very slow but on 12v they really go, so I will try them on 7.2 lipo if that's to slow I will try  11.1v lipo, that's when I have fitted prop shafts.

Hi David, We've been cruising in the Gulf of Bothnia - that's not a typo - its an arm of the Baltic Sea. Very good weather and beautiful scenery. I will get back to modelling sometime next week after catching up with the garden etc lol!

I have now fitted the prop shafts they are 5inches long x 4mm.












this shows the prop shafts fitted to motors, with  inserts fitted to some tubing.  I don't use the the red couplings I find then noisey .

I have spent a few days making the lifeboats . I drew out a small plan then cut out then fixed it together. 



started of with some 1.5mm card




cut out the frame work



then glued with cayno 



I filled in with some odd bits of foam, then coated it with polly filla then when dry rubbed smoth




after making plug I coated it in Vaseline. I mixed some plaster of paris which sets very fast and just pushed the plug in with some weight to hold down



when set I removed the plug, and made my first boat by putting some fine glass fibre matt and coated with resin. when set I pulled it out and gave it a coat of resin to loose the glass matting on out side as I didn't have any of the gel coat.




this is the first boat cast



these are the two boats ready for seating being made



one boat nearly done



this is the resin I use fast glass always use it for bits I need to cast never had any problems.
I have made some oars but cant find photo so I will show later in build

I have found the missing oars Very Happy .




the bottom oar is before sanding and top finished just used some bamboo skewers to make them and two coffee stirrers for the paddle part







this is the steps for the bridge and other places. made from card again 



these are some small steps 



the big length is what I have made the small steps from cut of every three steps.



all steps now cut ready for fixing in place the wheels I made for another boat and they go on the cannon.

I have been doing a lot of bits that need making. I have made the bridge from 2.5 mm copper wire then solder.




this is the frame work and ply for the deck



starting to make shape



ready for soft solder



this is the copper wire used its from household mains 2.5 wire striped from sheath



here you can see  clips for heat sink, stopping the heat melting the solder already done. I used my little pencil blow torch for all joints.

also while solder was out I made the hinge for the funnel which is split in the middle I used some copper and brass I had in stock



it sits on a cradle that I made from some wood.



I used 14 BA nuts and bolts to fix it in place




that's it for today I am prepping for painting and making more bits.

You're making very good progress David. That's an unusual funnel. I wonder what the reason was for having it fold?

Folding funnels aren’t unusual Barrie, they usually folded back to go under bridges.

Common practise back then for funnled vessels, that can go up and down rivers like the Thames etc.

I have been making some more small bits on my lathe first is the bollard for anchor chain

 
 I have used some  doweling for this 1 inch dia



finished  ready for cutting of





this is the heat shield that fits in front of funnel to keep the heat of the bridge . I used a toilet roll tube cut to shape.




next job I made the slide rollers using some copper tube and brass rod then bent over



here I have fitted them to the cannon frame.

I have also started the painting and fitting out all the small parts I have made. I will show the boat painted next time.
