New shrinker-stretcher for the shop

[MP&C]

Made a trip to Long Island to pick up a "new" s-s for the shop, this originally came out of a Northrup Grumman aircraft plant on LI. Here's the unloading device ....





....and located in the shop, anchors installed to keep it from moving.








To show a couple test samples, we'll use about a 4" long piece with 1" flanges. The result shown is after about 4 passes, with a close up to show the "finish" result.











Shown against a roll of tape to compare the radius size we've accomplished..





Here's a closer shot to show the stippling on the shrinker jaw....





.....and the shrinking sample....











These Lancasters are what it will be replacing....

grumman had lots of real nice equipment and raw materials too// my next door neighbor worked for many years in the calverton plant

Seems like those tools will last 100 years or more and never quit. Nice find. Should be a whole lot easier than yanking a handle 100's of times to get the same effect.
