H.M.S CRANE  flatiron gun boat 1872


I have finally made my mined up to build this model H.M.S. CRANE.  it is a contemporary gun boat ant class built from iron. the length of 85ft, beam 26 ft, and draught of 6-6.5 ft, (mine will be 23 inches x 61/2 inches) it has twin prop shafts driven by two steam (cylinder reciprocating engines) mine will be electric motors. the armament was single 10 inch  mlr (muzzle loaded , rifled). it had a speed of 81/2 knots and built of iron. this is a photo of it. I will be using all my scrap ply wood and other bits and pieces as you can see there is a ready made pack available. the plan no is MAR3524 from October 2011 marine modelling international now out of business sadly Surprised . I will be adding photos as I go along.

I agree gents, and a fascinating project too.

I am very glad to see and say that at the present time there are so many builds going on, within this forum, it is so refreshing to see such diversity.....

thank you all for supporting the forum so much with your postings.........it is easy to overlook such support, but it is you all who make this forum work, and I speak for us all, ........thank you and keep at it.

hi, finally made some progress with this model, I cut out all the bulkheads on paper. then I stuck them down with watered down p.v.a. on some 3mm ply. then i cut them out to shape with my jig saw, finishing them of on the sander. next I fixed all bulkheads with some 4mm x4mm square timber  I cut on my table saw. next job I fixed all bulkheads on building blocks held with clamps as seen in photos. next job will be planking.

i have been doing some planking over the past week, not much done but progressing. the wood I have cut down on my table saw. not sure what it is, it looks like some sort of Brazilian hard red wood a bit brittle but doing the job so far, so will continue with it.




first 2 planks secured using pins




a few more planks laid




it is very slow going only seem to be doing about 4 planks each day, also I have been using clamps to keep them tight together as well as pins. I will update as I progress.

latest update, I have now finished all the planking and it all went very easy as you can see from photos.




final stages of planking





all planking now complete and just had a quick rub down by hand before I use electric sander to remove any that have been proud




it all seems to have fitted well, just needs some bits of filler on some joints before I give it all a coat of resin. next job is fixing the stern and bow with balsa.

more work done on my build. I have cut out the front bow and stern from some 2mm ply using template. I fixed them on with p.v.a  glue held with clamps



bow cut out from 2mm ply












I had to make a curve so cut  down slots at 5mm apart then gently teased it round the shape of boat then glued down with super glue. 





I then put some 5x5 mm strips to support the tops of bow and stern ready for building up . to be continued later

I’m guessing the plan didn’t give you that detail in plating.

As for the real boat, very little info out there on it other than it’s dinensions and what it was,
In fact after an hour of searching around I’ve found more model related builds and kits than I did actual info on the real boat.
Even those models I’ve found gave basically zero info on the hull plating, I fact going of your plan it looks that most were build as smooth hulls and just painted, making this in fact a semi scale model rather than a rivet counters obsession.

Without any real info on the boat it’s hard to judge what you would need....

On that note as a suggestion I would make up some lengths of card as plating in various sizes and just sticky tape them to the hull and see what plating sizes look best.

Obviously this isnt entirely accurate but I also belive the plan your working from also isn’t 100% either so using best guess when doing some detailing jobs would put the model under artistic licence!

On the other hand I see no reason why you can’t just plate the model as a smooth hull and paint, now I know that may not be what you wanted to hear however unless someone has any facts I couldn’t find them your options are limited to smooth hull and paint, or best guess and template the plating until you found a size that suits.

Remember that’s what a lot of kits are likeexclusing some of the more premium range kits), they generally don’t have plating effects simply due to either lack of info or just didn’t want to mess around with that feature for build simplicity.

If going for the plating I would look around for boats of that period and how big a plate was compared to an avarage man, and scale that down to your models size. Not 100% accurate but good enough without going over the top.

thanks for your reply aron,

  it has some detail of plating but not sizes as you can see in photo.  I wanted to try some thing new to me I have looked and looked but
found nothing of any use . I think I might try doing it my self and experiment like you said. also I have been looking at neils build of the duke of northhumberland lifeboat, I will read it again and see if he says what size he used for a guide

hi ,
since my last post I have found out what they call cutting slots every 5 mm or so to form a bend with out steaming. I must say I use this a lot it is called KERF CUTS into timber to form bends it takes a bit longer but the result is good. progress with the plating is at a stand still while I still study it. I have now fixed the bow and stern with balsa, but as I have very little I have cheated a bit some of you wont like it but the finish has turned out good I think and that's all that matters.                                                                                                                                                                                                                                                                                                                                        

this is the stern done with balsa then sanded down




you can see where I have used the KERF CUTTING method where you cut at 5 mm intervals



this is how I did the bows using odd bits of balsa, as I said I had very little and didn't want to get any more in stock that . it will look good in the end promise




then I filled the inside with polystyrene and no more nails to hold it in place then a thin piece of balsa over it using p.v.a glue.




as promised here it is all finished and rubbed down. its great balsa for this type of work. I have given it a quick coat of resin just to harden the balsa and a bit of filler.
I found about KERF CUTTING  on another site by accident,  when I could not explain earlier when I said what I was doing and find it very interesting subject.

Kurf cuttings a great way to go on tight curves with larger materials. Used it many times before on adding deck supports, the slots also give a decent amount of glue surface for anything being stuck down to them!

I tend to avoid doing these slotted cuts nowadays having moved on to steaming laminations into the curvatures I want but early years of boating it was a go to method with great results.

the next job has been fixing the deck down I have used 2mm ply and p.v.a. glue. at the bow I have put some 1/4 inch thick balsa then sanded down to make it have a bit of a slope and round edge.





this is the deck before  being glued down.







 you can see where I have given the inside a coat of resin.
next job is the bulwarks.

next job has been the bulwarks I have used card again as I am a big believer in this product, it works well for me and have used it for most of
my builds. the thickness is 1.50 mm, I have also used corn flake box card as well, here we go.






bent this round with steam from kettle



fixed to the bow with super glue




tried to show the thickness of card here



final piece goes on it wants supports fitting all round next



all done now
