Any one have a Good way of forming wheel-well lips? I been playing with hammer forming patches and do all right as long as its a short strait bend but when its bending on both axis I have a hard time with it been thinking of trying Hard wood former? what works for you?

a shrinker stretcher works wonders, or a whole heap of tuck shrinking and then stretching on a stump and planishing.
pics help in showing which part your trying to make
try metalmeet forum, great guys and very informative

Hey Krem
Ya I know a shrinker & stretcher would work and I am looking at getting one but I don't like the tooling marks they make in the metal when using them so I would really like to learn more about doing it by hand like you said " or a whole heap of tuck shrinking and then stretching on a stump and planishing."

Just me but I enjoy the process my self its cool

Every time I go to that sight I cant find a thread for just basic stuff like what I am asking about Forming a 90 and putting some Tucks in it and start shrinking them in makes metal bend in one direction try it in the other direction and it all goes to pot, I could use a Bit more instruction from there, do you got a Link for just the basics?
I am ordering a bunch of steel sheet this week so I can make more SCRAPMETAL

I love seeing what true professionals can do with metal fabrication.
My visits to the metalmeet site were almost overwhelming with terminology being used that I do not understand completely.
It does seam that a Planishing hammer, English wheel and bead roller are absolute necessities if you plan to get serious.

Hi Jim
Ya I think so
I picked up a lot of the Harbor frieght junk now, most of which I have had to modify. OR FIX.
The English wheel especially, It is a noodle, I still need to weld more metal to it to stiffen it up. when I got it The lower roller skated every where side to side I completely rebuilt and redesigned the lower half so the roller would track strait and clamp up tight and hard with upper roller. Its still a noodle but I can make scrap metal with it.

The Planishing hammer deal from them is Junk but I havnt had to modify it yet it makes scrap metal, I have attempted to make some Dies for it but have most of what I need already.

I Went ahead and picked up a Throat-less shear tonight & a cheap 30 inch bending brake and that cheap shrink-er stretcher set all from HF.
I am gonna set them up and try them out in the morning, they wouldn't even sell me a warranty on the shrinker stretcher set so I know its junk!
Its the teeth in the Jaws I'm sure the metal is to soft to last any length of time.
I do have 90 days to return them though & I also got the the foot operated stand with it as well, something else I am sure I will have to modify in order to really use it! The linkage just looks way to flimsy.
I am just hoping I can at least knock out some rear window channel patches with all of it for the fire bird.

The Brake thing is Junk but it will make a 90 with the use of some Vise grips or clamps and for just forming up patches I think it will work fine. I will modify it though.
The Shear thing looks good as is as long as the blades have any kind of hardness to them.

i also went on ebay and Bought another shrinking disk the smaller one this time I hope it works as good as the larger one I have.

This guy is awesome with metal shaping by hand or machine, and he shows how to make the wheel opening in his videos, this is just a teaser.

Well The metal shrinker stretcher tools themselves work, I was playing with them on the stand with some scrap pieces of sheet metal.
The Kicker Stand itself had to be modified, The stand itself are made from sheet metal and came with two 5/8" 6" long bolts to secure the legs which would have crushed the stand when tightening the legs down my cure was to make 4 spacers to fill the area so it wasn't crushed when tightening the legs.
This could be done with a Hand full of washers but I had some bar stock that I cut up on my Lathe. Also the Shrinker/stretcher stand does not supply 4 bolts to secure them to the stand the instruction for the stand say they do luckily I had some metric bolts on hand.

The Throatless Shear is usable after setting it up and adjusting but leaves a lot to be desired its not a well designed tool but a cheap copy of a good tool but still usable I am sure it will last long enough till I can buy a well made American made one.

The Brake is a Cheap brake requiring you to supply your own clamps or Vise grips to use it.
and again im sure it will work long enough till I find a nice used 48" Box break.

Well I got the Throat less shear all bolted down and the el'cheapo break.
The shear cuts Metal like Butter in a Perfect circle if you want Not bad for the money not at all.
If you need a cheap one it aint bad.
The brake does its job as well Bends sheet metal with ease, Box break its not! If all you need is simple 90 degree bends maybe a poor mans Z channel or U why not it will work.
Jury is still out on the Shrinker and Stretcher combo Im gonna have to give that a thorough work out before I give it my blessing. (buyers beware)
Ordering a bunch of AK 1008 in morning after I work some of that with it I will give an opinion.

Well Its my Friday gonna spend the next 4 in the shop its all cooled off now even kinda cold out there I'm gonna enjoy some time with that Fire Bird project of mine maybe I will actually get something done?

I bought a cheap (read: Chinese Junk) metal break when doing the cab enclosure on this John Deere Loader:

About all it was good for was slightly rounded 90 degree or less bends, and that was after I adjusted, tweaked, hammered, and took an oath never to buy HF stuff again. :wink:
