Re: Arizona Gandy Dancers
Bill, with mixed emotions, sadly, I must advise they do not. No working breach mechanism on any of the armarmemt.
However, it could added. A bit of machine work and some interior naval architecture and I am assured you could go duck hunting to your hearts content. There certainly is enough room below decks to add all sorts of miniature machinery - even steam power plants if one were so inclined.
We do know all the gun tubes and deck hardware were hand made. turned down on a lathe etc, by the original builder. There is no vendor working in this scale, so the builder would have had to do every piece from scratch.
Seriously, there is a group of maritime battle enthusiasts who routinely go around sinking each other’s fleets. These boats maybe you wouldn’t want to do that with, as the yard time for repair would be extensive.

I think the shoot / sink group is German...and they were (are) using paintball gun mechanisms..
Lots of fun...all the more reason to shoot straight.

Re: Arizona Gandy Dancers
Well, the Bismarck was scuttled in 1941 after only nine months of service, after being beaten up rather severely by 16 British torpedo bombers, two battleships and two heavy cruisers. So to be prototypical.....

Re: Arizona Gandy Dancers
Yeah...that's them...
Now all they need are rail runs to lob in big shells to destroy the naval depot's

Re: Arizona Gandy Dancers
Back to welded rails... Rails that cannot expand lengthwise just grow in overall section - wider and taller. Real railroads get away with welding long strings because the track is well-ballasted to prevent sideways movement. The rails themselves resist lifting out of flat, because of their I-beam shape and their weight. Heavy ties help too. But they do want to jump sideways into what is known as a "Sun Kink" if the edge ballast is scant. In extreme cold, you also get "pull-aparts."

Re: Arizona Gandy Dancers
So, what does it mean when your post totally kills a thread? Is that a good or bad thing? I figured my post on 2-22-22 would generate some good discussion, but -- nothing...?

Re: Arizona Gandy Dancers
The large scale warships are an amazing deal in my opinion…I spent a good couple hours reading more on RC naval warfare. I had no idea it extended to such relatively large scales. I had only seen the tiny ones that zip around like speedboats.
On the welded rail…I wonder how well will the prototype practice scale? Also, have you worked out what the actual cost is to perform each weld?

Re: Arizona Gandy Dancers
Jam the ends together
Build a clay dam around it
Pack full of thermite. Light with mag ribbon or oxy torch.
Stand back.. wait to cool
Grind off excess.
Or am I missing something...giggle

Re: Arizona Gandy Dancers
Our current plan is to bolt 1 joint and then weld two- maybe three sections - for a total of 60’ or 80’. Couple of our 7.5” track crew have made up a rail car that mounts a gen set and a small Lincoln 100amp wire wire feed mig set to weld joints. We’ve duplicated that portable set up on a golf kart and can do 12# rail joints well enough. Welding cost is nominal for stick welders. Less than $1/lb for 6020 or 6011 rod. Two welded joints are 20x cheaper than buying two extra sets of fishplates and track bolts. So every welded joint saves us $19…
We think one of the key elements for controlling welded rail is oversized ties and substantial spikes/lags and rail clips. Hence we decided on 3/8” x 2 1/2” lag screws, with heavy gauge 2” fender washers. The washers in this case act as rail clips and are 1/8” thick steel. They are used in trailer construction to screw decking onto the frame, so are more substantial than typical DIY hardware stuff.
Also, standard gauge concrete railroad ties weigh in at something over 1300# each with a very heavy gauge rail screw and clip system. The extra bulk provides the foundation to tie the rail down to control expansion.
We can’t afford commercial grade rail clips ($1.47 each x 4 per tie ) so going with what we believe will be adequate for our 3” and 4” scale, low speed moderate weight trains consists.
The key here is that we feel 5” scale, 15” gauge railroading is unrealistic for most hobbyists. Hence we purposely are designing for the smaller scale equipment - with the occasional 5” scale visitor…,

Re: Arizona Gandy Dancers
I see I botched my meaning with poor wording Bill
I was thinking about restraining the forces due to the restrained expansion of the rails…how well does this practice scale from full size.
Glenn, clearly the material cost for welded joints is far cheaper, and obviously labor is free since this is a hobby . If you weren’t going welded, what would have been the cost difference of the other materials…possibly lighter ties, smaller/different hardware?
