boatman's 1/72 HMS Tiger C20 build

[Guest]

I can quite understand the need for the fans, other than the steam machine ,cooling the electrical motors in the hull .
Trust your soldering is up to scratch Chris! Certainly will be by the time those railings all all done .:thumb2:

Yeah Chris......ain't you lucky the stanchions came pre-drilled! Soldering should go pretty easy though, as it is thin material and will heat up quickly. Will you be needing to use a heat sink to keep from damaging the decking?

AN hello John yea these fans are gonna be needed though but its workin it all out to get it right to get the cooling effect that needed so a bit of thought will be needed there an:thinking: regards railing yea i should be good at solderind by the time ive done these lot if im still sane lol:rolling::smiling::smiling::smiling::smiling: but i may super glue them yet as i did it this way on my other ships like my type 42 HMS EDINBURGH an after nr 20 yrs or so they are still ok as my m8 still has her an i was lookin at this ship round his not so long ago an they still ok so i may try a bit of each on this subject to see which is eayiest an thanks to you allso for havin a look in

AN HI THERE Rick yea im lucky ok but with regards to these upright stanchions :thinking: (im dreading it) as ive treid to push a bit of the brass wire through these upright stanchions holes an some holes are ok but others are a bit to tight a fit so i think i will have to tape these uprights down an gently with a half a mm drill bit drill them out but with a bit or a lot of patience takeing my time an they will come ok as i said at the start of this build its gonna be yrs to build this model but some devoted guys spend half their lives on one model so i suppoce im the same a ship nut lol :rolling: :smiling2: an:thinking: regards a heat sink to stop deck damage well if i do solder them i think ive got a tiny metal crockidle clip to just clip it in place on the bottom of the stanchion upright an hopefully that should do the job ok but if i just super glue them in place then there is no need to worry about a heat sink is there but i will try it both ways to see which works the best an also to you Rick thanks for lookin in as its all you guys that give me the mojo to keep goin on this build thanks to you all

Hi Chris. Look at purchasing a five sided broach to widen the holes in the stanchions. It is less aggressive and more controllable than a drill. Broaches also keep the hole central, drills can allow them to wander.
Also, if you do solder them, put a piece of wet tissue under the crocodile clip you are using as a heat sink. It will make the heat sink much more effective.....

Hi Chris. No probs mate. I mean something like this...

https://www.amazon.co.uk/Modelcraft-0-4-1-4-Cutting-Broach-Grey/dp/B0037YCAYU/ref=sr_1_1?adgrpid=51264391137&dchild=1&gclid=CjwKCAiAq8f-BRBtEiwAGr3DgQaqjImHt56b4FqMM9e5zbaNMhrfSncvMFHTycV5ijdP_81veE1DohoCOqcQAvD_BwE&hvadid=259052646477&hvdev=c&hvlocphy=1007068&hvnetw=g&hvqmt=b&hvrand=4984841847765018125&hvtargid=kwd-297414247410&hydadcr=28149_1724799&keywords=cutting+broach&qid=1607673768&sr=8-1&tag=googhydr-21

They are gently tapered and used by inserting them in the hole and rotating them between the thumb and forefinger. They work really well on brass and plastic sheet and are much more robust than fine drills.

Just had a quick look. John has the same set in the shop, but his are a couple of quid cheaper......my bad for not looking there first....

HI Tim thanks for showing me these broachs as ive never heard of these before but to me they seem like a set of needle files ive got but i'll see how i go on these stanchions as i will be doin them soon cheers
all best

They are nothing like needle files Chris. They are basically tapered round in section and smooth apart from the five cutting edges. They do not have teeth. I’ll try to take some decent pictures of mine later so you can see what I mean.

Hi Chris. As I promised, here are some shots of my 5 sided broaches....



These are the ones I have, from really small (0.4 ish) to larger. As you can see, they are nothing like files. You can hold them in a pin Chuck, or between your fingers.


Here is a (hopefully) clearer shot of the biggest one. It shows that they are tapered with five equal flat sides. There are no teeth, the edges do the cutting. This enables you to gently increase the size of a hole, and the odd number of sides means it won’t drift off centre. Broaches are particularly useful if you want to make a hole big enough to take a wire of unknown size. You just drill smaller than the wire and broach the hole out to the size you want. For sheet work it can save you a lot on drills because these are more robust and you don’t need to keep every single size in stock. These are obviously no good for blind or deep holes though.

I find them an invaluable tool to have when dealing with etch, especially when building something with a lot of holes that need opening up. Well designed etch should always have undersized holes, because you can always open the holes to size, but if the sheet is over etched you can’t put anything back.....

Hope this helps
