Do you have a build log up anywhere? Would love to see your work.

I don't but do have a bit of information posted about it in the group builds.:

/forums/t/134344.aspx?PageIndex=185

Perhaps I could start a build log about it with all the work and problems I have encountered so far.

Why can't I find the "Any" key on my keyboard?

Glad to hear you got it bent. I would use caution heating pe up until its red though, you may actually start to melt of deform it.

I was careful, only heating it for a few seconds until it just started to to turn but no more.

I wanted to let you all know that the annealing process was a success! I clipped the corner of the part in a locking set of tweezers I have, got out the old propane torch, heated the part briefly until it glowed red and allowed it to cool! I was then able to use the kit part to mold it as it was very soft, almost like lead foil! I even had to be a bit careful because it bent so easily! Nothing more than my fingertip and a toothpick did the job!

Thanks all for your comments and suggestions! This also will come in handy when i go to add the radar, which requires a curved piece to be formed from a flat oval! (Part #91)

Yes, do the step first then curl it... Annealing will probably help.

There is another option though... IF there is a kit part that matches that shape. You can use some aluminum sheet or lead foil burnished over the kit part. Lead foil would be the easier of the two since it stretches easily. Burnish over the kit par and then cut it to it's final shape. If there is no kit part you cal still do it by remaking the PE part in lead foil. Just copy the shape and then bend it as directed. In any case it will be easier than brass.

 

Just my thoughts.

Well, well - I might buy this very PE set some day... It's not the easiest thing, but it's doable. Do the "step" first, by any means, then the "rounding". For the rounding you will probably need a tool - maybe you'll find something around the house, if not, you'd have to shape it yourself. Then you take the stepped part and roll it on the tool, and there you go. Hope it helps, good luck with your project and have a nice day

Tough part :)

If you can't use the part itself to bend on, I would use a small marker to bend and use the lid of the marker to help me do the step at the same time.

Impossible bend of PE part? Success!
Posted by jimbot58 on Friday, September 16, 2011 2:56 AM

I am working on an F-105G Trumpeter kit and am still pretty much a PE virgin, though Have had some experience. Tonight I am stumped.

If you follow this link to Eduards .pdf file:

...Part #53 is a flat piece that is not only to be rounded, but also it has a bit of a step in it. I Can't figure how to make the required bends while at the same time round it to follow the curve of the engine nozzle in the opposite direction.

I also hear of annealing the parts to make them softer and easier to bend, but I'm not sure of the way to do this. I have already separated the part from the fret so, I wasn't sure if I still can do this, and if it might help here.
