Replacement for 1/48 blast tubes & decal option question
Posted by 7474 on Wednesday, January 6, 2021 12:43 AM

What's everyone using to replace the blast tubes on 1/48 aircraft, such as the P-47? I would rather not buy AE, if I can buy tubing of some sort, I'd rather do that as I have several P-47s in the stash I'm working on and it would be expensive to buy several sets. I also have other allied fighters. Not sure what diameter tubing to get. I can't drill out the tubes straight. 

Also, does anyone make decals in 1/48 for Dottie Mae? Despite my internet searching, I can't find anything.

I've heard many people recommend hypodermic needles for barrels. Not sure of a source, though.

I've ordered steel tubing from McMaster-Carr, https://www.mcmaster.com/tubing, on a recommendation from a post at Modeling Madness years ago.  You could also use brass tubing, which you should be able to find at any hobby shop that has model railroad supplies, or online.
 
As far as hypodermic needles go, yes, they're a good material to use, too.  I don't have a formal source, but when my mother was still alive, she was taking blood thinners as part of her course of chemo, and she saved me the hypos.  I just had to disassemble them to get the needles out.

As was said above, tubing is available in almost all hobby stores and internet sites like Sprue Bros. and Squadron.

I have a sheet of dimensions for inside and outsite diameter of all types of barrels. I'll look for it today.

Also try K & S tubing.

Hi;

    You can get Hypodermic needles in some different sizes at most places that sell Farm Supplies. Farmers do have to do their own Injections on cattle Etc.  This is where I get Hypos for 40mm and other gun barrels. Also if you talk to your local Pharmacist they Might Help you.

Sprue Bros. sells packs of nickel and brass slide fit tubing. The assorted sizes are very handy, plus they do slide fit, so that making items with sleeves, jackets or blast tubes is easy.

Mr. Mike,  I've used concentric tubing for some of the propeller shafts instead of what comes with the model.  Not only does this arrangement allow the prop to spin freely, but also allows removal for transport as needed.  

Estimating that the OD of the gun tube is about 2", that makes the tubing required about 0.040".  That should be available at hobby stores and some home improvement stores.

OK! Here's the link to my Barrel sizing chart. Hope that it works.

PS - The part numbers on the right are for a company that sells syringe tubing in 6 foot lengths. The guys in the club chipped in and bought a couple of each size we used and cut them up and shared them. We had enough to last for a long time.
