draggie748 Posted March 21, 2021 Share Posted March 21, 2021 Greetings Fellow Modellers, I'm looking for drawings or leads to such drawings of the underwing pylons for the T-33 ECM cannisters that the USAF used. I have searched all my links and print references, but have had no luck. All help is appreciated. Thanks Phil Canberra - The Nation's Capital Australia Link to comment Share on other sites More sharing options...
72modeler Posted March 21, 2021 Share Posted March 21, 2021 See if any of the information in the link below is of use. I would imagine the pylon shown in the B-57 walk around would be the same one as was used on a T-33. Do you have a scale in mind? If so, I think one of the 1/48 T-33A kits might have a pair of underwing pylons. From the photos, it appears that USAF A-1E/A-1H Skyraider or F-100 pylons might be the same size. Looks like they would be pretty simple to make from laminations of plasticard.

Murph Posted March 22, 2021 Share Posted March 22, 2021 One thing to note is that the pylons were permanently attached, so they were not uploaded and downloaded or swapped round. You'll need to find a picture of one with pylons to ensure that airframe actually had them mounted. Regards, Murph Link to comment Share on other sites More sharing options...
Rob de Bie Posted March 22, 2021 Share Posted March 22, 2021 Here's a reasonably good view of the pylons used for the ALE-2 chaff pod: https://www.alamy.com/stock-photo-lockheed-t-33-shooting-star-showing-chaff-dispensers-under-wing-55263958.html It looks like a simple shape to me. Maybe you can find more photos, so you can do some measurements. For comparison, the ALE-2 is 13' 10.2" long and 19.58" diameter. I scratch-built that ALE-2 chaff pod for another subject.

draggie748 Posted March 23, 2021 Author Share Posted March 23, 2021 Gents, Thanks for all the replies. I think I now have enough info to graft a couple in 72nd scale for my build. Murph, the aircraft I am modelling does have them fitted. 😁 Cheers Phil Canberra - The Nation's Capital Australia Link to comment Share on other sites More sharing options...

Rob Rob, Very nicely done on the ALE-2. One humorous note on the pod is that there was a seafood store not far from Pease AFB, and the containers they packed their live lobsters in fit inside the ALE-2 chaff tray perfectly. I'm not sure which was one sized to the other in this case. Regards, Murph 1 Link to comment Share on other sites More sharing options...

Reminds me of when we were stationed at Dyess AB, TX with the 516th TCW flying C-130's in the 60's. When the guys would go TDY to Alaska, they would come back with crates of King crabs, chilled suitably during the return trip. Our next door neighbor was the check pilot for the wing and always told his wife "Daddy's comin' home with the crabs! Big buying frenzy on the ramp. Those were the days!

I use Sika G27, but yours seems to have more pot time. Andy Link to comment Share on other sites More sharing options...
Rob de Bie Posted March 25, 2021 Share Posted March 25, 2021 I use Smoothcast 305, its pot life is just perfect for my methods. Here's some data that I collected some time ago: Type potlife demould shrinkage Biresin G27 2 min 15 min ? Smooth Cast 300 3 min 10 min 0.5% Smooth Cast 305 7 min 30 min 0.35% Smooth Cast 310 15-20 min 2-4hr 0.025% Rob Link to comment Share on other sites More sharing options...
Rob de Bie Posted March 26, 2021 Share Posted March 26, 2021 I forgot to include G26 and the viscosity numbers, so let me try again: Type potlife demould viscosity shrinkage Biresin G26 3-4 min 30 min 70 mPa.s ? Biresin G27 2 min 15 min 30 mPa.s ? Smooth Cast 300Q 0,5 min 4-5 min 80 mPa.s 1% Smooth Cast 300 3 min 10 min 80 mPa.s 0.5% Smooth Cast 305 7 min 30 min 80 mPa.s 0.35% Smooth Cast 310 15-20 min 2-4u 80 mPa.s 0.025% G27 is really thin, which makes casting easier, but the potlife is just too short for me.
