Default reverses

I had a few more suggestions for reverses in general:
Some of these ideas are best suited to smaller parts, but maybe they'll spark some ideas for your larger parts too.



This stake is made from a loggers cable pull, welded into a piece of pipe. You buy them rough and have to clean them up but they are nice and hard. It is one of the handiest stakes I have for small reverses.







This part goes on the back of the birds neck. There's a lot of shape in it.



This is another hammer modified for slightly larger reverses. This one would not be found in TM Technologies catalog.

I wanted to add that the forming stake can be straight and still work fine if you lift the metal off the stake and strike just off of the point where the metal touches the stake. Having a curved stake does make getting the shape smooth, easier.



Lastly, an assortment of air hammer dies for different degrees of reverse shape. These can save a lot of time over hand hammering in some circumstances. Reverses can be mind benders. -My $.02

@ Gene Olson: I'm not working on a particular project where I need this shape. I'm just trying to teach myself and collect different tools and did not find much info on this shape.
Generally my projects will be middle-sized, furniture / bicycle parts and such.
This thread really shows a variety of tools, tips and projects and that's exactly what I was hoping for. Thanks everybody for your input.

Hello mark,

WOW! Nice work, i love the birds. mother nature has create the best looking shapes. i really like your interpretation.
you have some nice tricks in your "toolbox", i would love to see a little more. how about a shoptour ? what kind of airhammer are you using? these reverse curve dies are looking very usefull. could they work in a pullmax too, what do the other guys thinking?

Default saddle dies

I appreciate the responses and comments on the work...

The saddle dies do work in the libert I converted, although they're much faster in the air hammer. I don't have much time using the reciprocating machine yet. I am still learning the differences in the ways in which each style of machine moves the metal. But, they've worked well enough in the libert so far to seem encouraging.

As Kerry pointed out in a previous post they work similar to a "hot dog" die, which he demonstates using in a reciprocating machine.

Maybe these should be new threads.

Yes. Exactly, the same process. The Hot Dog Die thing came from Terry Stolarski. I documented it with his permission.

However, using a hand process allows much more control. It's easy to go too far using the hot dog die.

thanks, mark and kerry, for your explanation.
i have already made a hot dog die for my pullmax, works nice. but i could build some more lower dies, with different curvature, if i need them.
