Shrinking hammers & dollys, and shrinking in general

I've got a pile of body working hammers and dollys, including a shrinking hammer I bought.. I'ts been a while, and I did most of my learning (especially about shrinking) through trial and error (about 10 years ago). Anyway.. I don't have a shrinking dolly, is it necessary to have both hammer and dolly? What should I know/bear in mind having a full assortment of regular dollys except for a shrinking dolly, plus having a full assortment of hammers and spoons.

Also, are there any good guides on heat shrinking (especially about where I want to pick my spot to shrink, and how big of an area to shrink at once?) I suspect I've forgotten everything I learned through trial and error years ago aside from how to heat then cool to shrink metal.

Hi Slipangle,
In my opinion, your best bet would be to take your shrinking hammer straight to the forge and make a useful tool of it! Same goes for shrinking dollies. It just gimmicky crap!! You're number one tool for shrinking should be a shrinking disc. There is a message posted already about this tonight. Have a look at the shrinking disc topic for more details. If you want to learn how to use one, let me know and I'll be happy to post a tutorial on how they are used.

usually only auto body pros can use those, theyre kinda hard to use and if you dont know how to use them you can get more damage than fixing. I just use oxyacetylene setup for shrinking metal.

shrinking disks aren't hard to use, and the nice thing is that you are far less likely to over-shrink using a disk than using a torch. With a torch you are putting so much heat into such a small area...you're just asking for trouble.

The shrinking dollies do work also, although they come at a cost. It really eats away at the metal when you use them.

I have used a stud welder gun with a shrinking tip on it.Works great,especially if you have an "oil-can" problem.
