1 72 scale scratchbuilt 38 cm Max railgun dio.

Thanks Barry, but I have to say I'm a bit confused.:upside:

If the counterweight is immediately above the pivot, it will have absolutely no effect in terms of balancing the weight of the barrel (Physics 101 - the turning moment is the product of the mass x the distance to the pivot. If the distance is zero, the turning moment is zero).

It does look like it is movable though as it appears to have pivot points at the bottom. Is that right?

Yes the pivot point is at the bottom and it folds flat along barrel see wikipedia link

Here you go chaps.

Dug out from t'internet.

I quote....

"...was simply to counter act the preponderance of weight towards the breech. Although heavy, was simpler than adding equilibrators to perform the same function. Folded when travelling"

Well that got everyone talking
,I don't understand physics of these things I just get as much info and photos of what I am building as I can and go from there ,But I draw a line on building some guns as I cant get enough Info to make a model that is close to original and as I can , and I have mentioned before I don't pretend these railgun models are 100 percent accurate but as there is no kits of these models and lt is as close as I can get , I build it to have a representation of a model I want and I love Railguns.

I am not knocking all your I interest in this model and am enjoying your interest and comments on the build.

Barry, whatever the purpose and function of that counterweight, that's a brilliant model and dio, well done, especially given that there isn't much information available on the gun.

Don't worry Barry, I don't understand the fisics either!

It's a great model, and no mistake, and I know no one was questioning the accuracy. We were genuinely intrigued as to just what that 'lump' was, and it's function.

Thanks Ron and all guys I know know no one was knocking the model and I enjoyed the discussion.

Absolutely fantastic, as is your norm Barry!

I certainly wasn't criticising your build Barry, or its accuracy. I was merely curious about that thingumajig. While I'm still not totally clear about how it works, I know it's some sort of counterbalance and I'm not curious enough to dig any further! :smiling:

Keep up the good work!

Thanks Dave , I would not bother either but need to find out more if I can.:sick:.

Hi Barry,

While all the scientists are at the Counter Weight Convention, I just want to say that this is truly a phenomenal piece of scratchery Sir!!! I don't know how you do it or find the RR parts, but in 1/72 scale, it is amazing.

I would imagine that this in 1/35 scale could take up half of the living room. About how long is this piece of arty and where do you get the cool figs??? TIA.

Thanks Allen, the model is 20 inches long and I source wheels from 00 gauge railway wheels , some of the barrels are made by a mate with a lathe. All the rest of the model is scratchbuilt this is my twelfth railgun build and I intend building three more, God willing.
Figs are from milcast models.

HI Barry trueley a phenomenal build as i like to look at these big guns as it amazes me where they can be hidden from air attack but my fav is the biggest an its dora isnt it ? ps an how heavy are the shells for this gun ?

About how long is this piece of arty

The real thing was 31.61 m long, so in 1:72 that would be about 44 cm.

Simply Stunning work.
