Model Forum / General / Models / February 2006tubing for .30 & .50 guns
Hi all,i was wondering if anyone here can put me onto the info for what size tubing could be used to replicate .30 and .50 MGs on 1/48 scale aircraft(USAAF). Also,what material is better to work with?Brass,Aluminum,what's your favorite and why? Thanks for any info on this.

This is VERY small. I have heard of surgical stainless steel tubing with this small an ID, but not the normal brass or aluminum at hobby shops. On the other hand, you might consider sizing by OD and let ID fend for itself. In this case you would probably use 1/16, the smallest you can ordinarily buy (as in K&S). Use brass 'cause in that size the aluminum is a bit fragile. The gun will be OVERSIZE in OD, but won't look too bad. If you want to really scale it accurately, you'd need a hobby lathe and start with brass rod, drill end 6 mil, turn OD to proper size.

I don't remember the needle gauge, but they seemed to be the type that would really hurt if you got poked with them. So, if you can get some needles, that would be the way to go, they are stainless steel and have the proper bore. Ray Austin, TX ===. Best 1/48 scale .50 cal. gun barrels In my oppinion the Karaya barrels look the best, since they are a scale diameter, and are perforated to match the actual jacket. They do not make a .30 gun yet. Also note that the perforated barrels would not be seen on a P-47, since they were covered by the steel jackets. But any bomber that had .50 cals are an excellent option to use the karaya guns, they are also available in just the barrels if you don't need the resin receivers. http://www.karaya.ceti.pl/eng/browning.html Dave > Teresa Voyles wrote: > [quoted text clipped - 17 lines] > Austin, TX > ===. King's Hobby here in Austin sells small cut sections of SS tube in at least two sizes. The small envelope I have at hand is labeled Minimeca Ref 119, Tubo 0.80 x 10, 20 unidades. Looks about right for .50 cal. Also you might want to check out .50 cal. barrels and cooling jackets from Karaya, also at Kings or found online. At one of the shows last year I found some lengths (about 8 inches) of steel tube at should work very well. Wish I could remember the vendor.

To cut it I put it in a pin-vice and use a needle file to file a groove around it ,and snap it off, put it back in the pinvice and square the end off . I think I used 16guage in my Revell 1/32 P40, which I got from my local vet ,they use bigger sizes on horses and cattle , than on humans . SignatureKevin (Bluey) "I'm not young enough to know everything." bluey69@westnet.com.au You might want to look at this: http://www.smallparts.com/products/descriptions/htx-xtw.cfm Small Parts has all sizes of stainless hypodermic tubing ranging in price from about $2.50 for 6" to about $25.00 for 36" lengths.

The big benefit with stainless steel tubing is the walls of it are quite thin and as such look much more to scale than brass copper or Aluminium, these metals need to be thicker in the walls to give the tubing some strength. I also a small bit of hypodermic tubing stuck into the nozzle of a bottle of Veleao Plastic putty and us as a miniature chalking gun, yes it does work and the putty flows through the stainless steel tube, cut about 1cm in length. You can apply a neat controlled line of putty alond a join seam etc and then wipe with a wet finger and it's just about perfect. Our vet said catching something from the used hypo's is remote but to be sure I soak the in Metho for about 48hrs just to be sure regards JimboD > You might want to look at this: > http://www.smallparts.com/products/descriptions/htx-xtw.cfm [quoted text clipped - 10 lines] >>Regards, >>Kelly Voyles |
