Is there such a thing

[panzerjager2]

So for those of you that have followed my Panzer III build, (THANK YOU), you know I am in the midst of re-doing the barrel. Now the question I have is......
Is there such a thing as a rifled/groved barrel that I can add to my scratch built barrel.  Now the dimensions of my barrel is 5/32 outside diameter. With what I have created, I was wondering if there is some company out there that makes such things as a barrel sleeve, you know a groved insert that I slide into my existing barrel.

Just wondering, MANY THANKS in advance

Not that I know of....I know a 1/35 Mörser kit has one...Inside the Armor's 1/16 upgrade for the FT-17 had a sleeve. SO it is possible one might one might be out there. I am wondering if photo etch for Railroad fanatics might have something ribbed you can use.

Did you not want to have a go at it?








5/32? I/D or O/D? ...either case, maybe some 0.005" styrene sheet with either strips 0.01 x 0.02 or cut your own about 0.5mm stretched sprue?

I popped a couple test pieces...because I don't have anything better to do at the moment...








If nothing else, the thicker strips look like crap if you ask me.  I stretched some sprue and had a go.  Cut the small strip as I previous did...I think it looks fairly credible.  I would suggest letting it sit for a bit and then running a sanding stick over the trip before you cut and fit.   Probably would look better coming from a scratch modeler such as yourself and taking the time to space the sh*t correctly.  I would also put more of an angle to get more twist.

T,
Excellent info...............  After seeing your post, i got to thinking, I have some 1/30th corrugated tin. So I'm gonna try that technique you showed using my tin...UPDATED to follow.

LOL...Go for it! I was looking at a corrugated tool I have thinking if it would work...the scale was too large though. I wonder if you could take a fine tooth saw blade ( you know the ones I am talking about) and drag it a couple times to score some thin sheet stock and make it happen! I thought of tossing a course file down the tube...if it fit snug enough and just push twist it a couple times. LOL....if you can't tell, I am still waiting to get back onto the cave and try and be productive today!

Actually there is such a thing, but with the advent of metal barrels, they're probably rare.

I have set I bought years ago, forget at the moment, the name of the company that made them. They're made of PE but they only cover the end of the barrel maybe 1/2 an inch or so.

If I can find it, you can have it. I assume you need a 50mm for the Pz III? I have used a few so I'll double check and see if I have them left. They made several sizes on one sprue.

Let me know, Paul

Paul,

Thank you for your very kind offer......... My challenge is that I needed an insert for a 1/25th scale Panzer III Kwk 39 L/60. As you can see from my build log, i have the gun and am VERY happy with it now. What I seek is a rifled insert. My original thought was something like a 1/35th scale 75mm or even 1/48th 90mm.

A company from before the beginning of time, Om The Mark Models had a p/e sheet of 1/35th rifling. However finding one would be a miracle.
