Hi from Dave in Washington State

I'm not sure what I'm supposed to do here but there was a warning that I had to post an introduction so here it is.
I am retired in my 60's and have been working with metal off and on for 40 years. I have a few smaller lathes but the goto rig is an old Grizzely 12". I keep thinking I will replace it with a newer one but never get around to doing it. I added the larger Harbor Freight mill/drill about 15 years ago and it seems to do what I need but really was improved 2 years ago when I added power feed to the longitudinal axis. Welding skills are very minimal with an oxy/acet rig, a HF 110 volt spot welder and some mig wire feed thing.
Sheet metal: HF 3 in one machine borrowed from my brother, HF bead roller I powered up with the 12 volt four wheel drive change motor from an old 90's truck I used to have and that runs off of a battery charger. Miscellaneous homemade dies, tooling and big junk box with modifications made to equipment as I go along.
My current project is a Piper supercub clone I am building. I found this forum while searching for information on crimping dies like would have been used by Piper in the forty's to form the .016 "T" section their ribs were made from. I am building the small "in between the main ribs" nose ribs for my project and have run into a bit of a snag on getting the "nose" to bend into a tight enough radius. I am afraid most of the crimping dies are for stove pipe and won't do the depth of crimp I need. I have solved the problem of making the "T" section and that is well under way but the crimp is eluding me. There is a youtube film "Building small aircraft" from 1942 where it shows the building of a Piper J3 and at 11:00 or so minutes it shows a Niagra power roller doing the crimp I want but that's all I have.
