Bandsaw Steve Posted January 20, 2021 Share Posted January 20, 2021 Thanks for that.👍 Strange to relate; I work for one of the world’s largest copper mining companies but wouldn’t have a clue where to buy the finished product. 🤔 1 Link to comment Share on other sites More sharing options...
Steve D Posted January 20, 2021 Author Share Posted January 20, 2021 Etchings finally arrive today I can get back to the build sequence in my head As ever, let's start with the biggest item, the Bofors platform First fold lines on centre section done and the insert upstands soldered in place I'd previously turned the gun mount, this is how it fits in on its leg frames. The upstand clears the mount with only about 5 thou to spare, why do I make stuff so close?? Some time later, the wings are fitted with the tubes that will hold the stanchions installed, its adjusted, cleaned up and ready to dry fit. This has cross timbers and then the planking to add Dry fit with the gun mount enriched with bolt rings that no-one will ever see and the kitchen chimney temporarily in place And here's a teaser for Arjan, the beginning of the Bofors, note the recoil spring detail Tomorrow, the guns....

Arjan Posted January 20, 2021 Share Posted January 20, 2021 Your photo etched parts really look very professional. I'm looking forward to the finished guns . By the way, the ebay seller added some new photos of S-46. Regards, Arjan 1 Link to comment Share on other sites More sharing options...

Greg Law Posted January 21, 2021 Share Posted January 21, 2021 Great build Steve. Some impressive skills on display here. The Sboots are one of my interests. I scratch built a 1/48 S10 back in the mid nineties. I'm impressed with your hull shape. I bought the Italeri 1/35 one when it came out, but was disappointed with the bow shape. It looked too blunt to me. In the end I sold it on. 1 Link to comment Share on other sites More sharing options...

Thanks Greg, I agree, the hull looks simple but it is a very subtle shape and the bow is actually a nightmare. Being so nearly straight accentuates any flaw, there is no where to hide.. I've found it a real challenge, in a good way of course. Thank you for your nice comments, more build to come Cheers Steve Link to comment Share on other sites More sharing options...
Steve D Posted January 21, 2021 Author Share Posted January 21, 2021 The problem with the way I build these models is everything is a prototype. Some work, some don't, some need a lot of help. With the printing, its now easy to adjust the model and re-print. The etching is different, each A5 sheet is nearly £100 and so the decision to re-do is a major one. The 20mm flak today fell into the "needs a lot of help" category. First, the two support sides wouldn't solder, just no way to hold them in place, bad idea. Then I added a reinforcing piece and the frame wouldn't sit down nicely in the tub. Much filing later, I'm almost happy with it but I've got no way to re-do it so its a keeper. The shoulder braces had a mind of their own, I simply could not get that weird cylinder exactly the right length, no tolerance with a 0.5 mm hole, etc etc. Just one of those days really Anyway, its in and staying At least the hatches worked fine, forward view below with the two hatches in primer I'm sure it will look better once painted Then on to the Bofors, these are the parts, plus some rod and tube And here is the 4 cm gun with the breech sides and elevating quadrant soldered on (teeth not filed in this shot, I've done that now and the barrel is not fixed yet so the recoil slots are not in the right place in this shot). Hole is for the trunnion I'm more hopeful for this one, on to the mount tomorrow Steve 16 Link to comment Share on other sites More sharing options...

Steve D Posted January 22, 2021 Author Share Posted January 22, 2021 30 pieces so far, recoil cylinders, traversing gear, gun sight frame and seat frame to go, plus that unusual curved shell case chute () , this one is a marathon not a sprint...

Steve D Posted January 25, 2021 Author Share Posted January 25, 2021 Some part so this build are a challenge I enjoy, making the guns is one of those, at least now they are both complete. Over 100 separate brass parts later, the 40 mm Bofors is ready to prime I'm really pleased to have that bit done in a way I'm happy with, it makes or breaks the model Ammo cartridge will be printed btw, there are limits.....

Actually looking forward to seeing it painted and weathered so I can highlight some of the detail you can't see clearly in brass.

Bandsaw Steve Posted January 25, 2021 Share Posted January 25, 2021 That bofors gun looks absolutely awesome. I assume you soldered most of it? Or used two part epoxy? BTW - I bought a smallish sheet of copper at my local hobby shop on Sunday and a ‘ball & pein’ hammer at the hardware store. Not sure what exactly I’m going to hammer out of it but I’ve got a couple of future projects that might feature some copper bashing. 🚓👮♀️ ‘You’ll never take me alive copper!’ 🦹♂️ 1 1 Link to comment Share on other sites More sharing options...

There comes a point where more adding pieces with solder paste is too hard to control unsoldering other pieces in the process. The tube to tube T joints are all hard soldered, soft solder is just not strong enough. Really, initial sub-assemblies are silver soldered, then soft soldered together. Occasionally, I use solder wire when I need the joint to have strength, its all a matter of practice and multiple errors... 2 part epoxy is too messy (at least the way I use it)... If you have a pin hammer, you need to buy a doming block, let the fun begin... Cheers Steve 4 Link to comment Share on other sites More sharing options...

Iceman 29 Posted January 25, 2021 Share Posted January 25, 2021 Great job Steve, Fascinating ! We did the same work on 40mm Bofors but not with the same materials. (1:48).. 😂 8 Link to comment Share on other sites More sharing options...
