Shrinking stump fabrication
Hello everyone! I have been a member for awhile and figured it was time that I contributed. I have started a youtube channel that has been a great learning experience for me. I just uploaded my latest video where I fabricate an unconventional shrinking stump. https://youtu.be/GDjd3wXvQB0
I hope you enjoy. I would also love to hear critiques about it so I can learn. I am hoping to upload more videos about my journey to improve my metalshaping skills and I am all ears!

Nice stump Dave. I'd suggest you'll work a lot less and be more effective if you dump that tear drop hammer and make/buy a 'Winsett Hammer" (baseball bat hammer) or shaping hammer from Hoosier Profiles or Imperial or ?? IMO you need more weight to put the metal into it's plastic state.
Here is a thread on making one: https://www.allmetalshaping.com/show...ght=bat+hammer The only thing I'll add is to put the handle at the balance point, not the middle. That way you can easily spin it from one end to the other. I do the majority of my shaping with a Bat Hammer.

Thanks Kerry, I mostly work in 18 ga and you are right, I feel like I am beating the heck out of it. I definitely need a better/heavier hammer. Thank you for the advice and the link. I have been doing shaping for a few years, but still feel I am an amateur. definitely looking to upgrade my skills

Dave, it looks a great stump and well thought out. I agree with Kerry though, throw the little mallet to one side and get yourself a decent blocking hammer, it will save you a lot of time and effort!
Out of interest, what sort of lifespan would you expect from the stump, with it being made from plywood?

Thank you! I definitely need a blocking hammer! I have used it a few times now, hardly any real damage to it. If it does get damaged I will sand it again. Hopefully it lasts a few years since I do not metalshape professionally, it is a passion only/hobby

Dave bought this blocking hammer from me. I bought this from Joe Andrews at Metal meet Maybe 15 yrs ago. Due to the arthritis in my wrist ,elbow and shoulder ,I can't swing a hammer very long. When I do ,it takes a few days for me to recover. I watched Dave's video and along with many metalshapers felt the pain of watching him wail on that sheet metal with that light weight hammer. I'm looking forward to seeing his next video once he gets accustom to his new hammer.

That is for sure! Better to set up for endurance!

That deep of a crater of a shaping stump is humanly impossible to use to produce results with the very limited force that a human can produce. Shorten up the free span of the metal across the crater is the first step. Long radius curves can be obtained by utilizing a short span crater.
The shorter the span the more stretching will be achieved. Think a little at a time will get the results required. Remember humans do not have a great amount initial force but can exert a little force over a long period of time. Try shortening up that span. I have ground a crater with a radius of 5 inches into a roughly flat river rock and using a wooden mallet with a domed end to produce panels with very long radius Ed and very short radius Ed as little as 8 inches. Though I think I could form as small as 5 inches. Any way shorten up that spam and use many hits. Also use temples to check your progress. Mike |
