Quick how to make a shrinking stump and how to use the stump to shrink sheet metal. metal shaping. Thanks for watching. Please subscribe, like, comment and share!
How much time and money could've been saved if only RU-vid was available in the 80`s. I`ve been stuck, pissing away my life behind a computer for the past twenty-seven years, doing a job I can`t stand. If you can`t find something that appeals to you now days, and via RU-vid, well... you might just be lazy! Best to you and yours for sharing this!
Thanks for sharing and the quick tutorial, I'm getting my stump today to make my shrinking stump. Your vid answered a lot of questions. Thanks once again
when working with steel I was taught to start from center on shallower depression and gradually work out. When its just deep enough that you can move the material to touching the bottom of the depression is seemed to work better, less bouncing around, and easier hammering.
Jonathon Driscoll That would work if the dish in the stump matches the radius of the piece you are shaping. The way you describe it you are shaping a piece by stretching the center. This video teaches how to “shrink” the edges of metal. There are times when you need to shrink the edge to create a shape and you don’t want to stretch the center. There is always more than one way to skin a cat.
I'm planning on making a fire pit about three feet round. Would you first make a small bowl. Then weld a larger ring and then stretch it to eventually get it three feet across or would you do it all in one piece? Great video. Got my stump and the bowl made and I had the wood hammers. I've been shrinking all kinds of stuff.
Todd Elliott Yes, hardwood is preferable. Oak would be great if you can get it. This stump was from a large elm tee I had cut down I let it dry out for a few years before putting it to use. I have two large solid elm stumps that are about 10 years old now. They aren’t going anywhere anytime soon. A solid stump that is allowed to dry out slowly will work and will last.
Fantastic video. Is there calculation for what size you start with to get the the size of a bowl? My bowl's work hardens and I normalize them. Seems to work easier and doesn't crack. Is this the way they make those bullet that the 50's cars had on their bumpers. I do this 1/2 at a time and weld them together.So far not so good but I'm getting better.
I have multiple stumps with shapes cut into them. Different shaped stumps just like different shaped mallets, hammers, dollies. People ask me why do you need so many different shapes and size mallets (I have a lot). My tongue and cheek response is, Why does a socket set have so many sockets?
Nice work, kudo's. Showing the striking face and reason for it will help with all those hammers you made. I am just starting shaping and have making rings from coins is about it. What about a hammer with a radius face that matches the cutout in the stump? Good or bad I like to see a finished product as I mat learn from your difficulties with a piece.
I have a lot of mallets in different shapes and sizes. I do have a stump and a mallet that I made that were a matched pair. I made them specifically for a project I was working on. So yes, there are no limits to what tools you can make to get the job done.
get an old empty large propane tank cut the top off square cut the foot shroud off fill it with concrete nice convex dome, u could add to that like you have done with your stump..good idea u have there. Regards
I've seen that done. I prefer using a wooden stump for shrinking. When the stump and the hammer being used are softer material than what you're shrinking the process is more effective. But there are always exceptions to the rule.
How many hammer blows to your fingers before you perfected the art of hammering ? Been there, done that, and even spent several nights there. LOL Great video, very detailed info...
I am building a metal spinner for turning flat steel into a concave surface because I don't like beating the metal into an uneven stress condition and then smoothing on an English Wheel.
elena olivares Spun steel and aluminum is great for symmetrical shapes. When you do “tuck” shrinking the metal is not stressed. It’s actually very happy with its new shape. The metal is changed at a molecular level and the shape is very stable.
There are different processes a person can use for a teardrop shape and fenders. That's where experience comes into play. Knowing what techniques to use to achieve a shape is the art. Just learning the technique is the first step.
Trev Cessna172 There are many ways to shape metal this is one technique for “shrinking” the edge of metal. What you are describing is obviously stretching metal. We use different tools and different techniques when necessary to do the job. I have probably 15 different shot bags in my shop of varying sizes and purposes. Even shot bags that are designed for shrinking like with a dished stump. If you are not using shrinking methods in your metal shaping you’re missing out...just saying.
Some people do that. If the stump were to ever dry out enough to fully crack i just figure its time to replace the stump. ;) Keeping the stump from drying out too fast is what keeps them from splitting. Thanks for the input.
C List That’s not what annealing does for the metal shaping process. Shaping aluminum that has been annealed will still need planishing and metal finishing. Annealing is a tool/process that is used when needed to combat the effects of work hardening. Sometimes you need it and sometimes you don’t. The same way stump shrinking is a tool that you use when you need it.
I like to have a good sized flat section on the stump as well for planishing. It also leaves me room to cut in another size/shape dish if I need to. But there is no reason why a person couldn't cut it in the center if they wanted to.
@@stark6837 so what your saying is you wont watch someone who maybe giving great advice but he does not follow the same safety standards that you do! hum? that's your choice but don't tell other people to change just for you. you know you should wear ear protection. and that's all what matters.
As a woodworker of 30+ years, I find your plunge technique worrisome. Plunge cuts are inherently dangerous, the best way I've found to limit the danger is to put the front of the saw foot down on the work before starting the cut. Now I'll watch the video and learn something.
I guess we have something in common. I as well have been doing woodworking for 30+ years. I guess I don't see it being any more dangerous than having used a chain saw to cut the tree down and cut the stumps in the first place. I think circular saws are just inherently dangerous. Thanks for your concern.
@@SnapFabrications you controlled the saw very well, in less experienced hands it would probably be flying across the room. I would have rotated the saw and eliminated much of the chisel work, but that's also not something I would recommend for those with less experience. The best part about this video for me, is that it features one of the few metal working tools that I can afford.
Circular saws are inherently dangerous. I don't believe this is any more dangerous than having used a chain saw to cut down the tree and cut the tree into pieces. Thank you.
