Thank you for freely sharing your wealth of information for beginners like me. Your channel provides so much good information that would otherwise take years to figure out.
Of all the vids I have watched, this one taught me more about what to do to get predictable, repeatable results(especially, with little to no experience) than any of the others I've watched. Thank you.
Denis, it's amazing how often simple math is used, even in Industry and in Engineering. When I was a young Engineer (in the '80s), I needed to determine the center of mass of a relatively large part based on the drawing, which I was lucky to have, so I used the same techniques you show here to calculate the needed information. I went far enough to calculate the part's weight and compare it to that given on the drawing (known to be very accurate) as a check on my work), which gave me a warm fuzzy feeling after many hours of calculations (it was a complicated, hollow part!). But my point is that your calculations/techniques definitely work and for the relatively simple shapes we make as Blacksmiths, the calculations & drawings/sketches (which _definitely_ DO NOT need to be done on computers for those without CAD experience!) can be done in very little time!
Great video, there's not enough videos on UA-cam about "shop math" a lot of new blacksmiths don't even know where to begin trying to figure out how much stock is needed for a project. Most of the people that I've talked to about some kind of formula or ratio of starting stock to any give project have said to just experiment and eventually you will be able to tell by eye how much material you'll need for a project.
Excellent!! Good idea to think and draw things out. The original 1914 edition of the Machinery's Handbook has two (2 ea) dimensional diagrams/charts along with drawings for tongs in the "forging" section, (page 1186). Each tong on the chart has different dimensions, including length and jaw size depending on it's holding capacity. Very useful !!
Interesting work, never thought of forming a patten like that before! I always just cut off any extra and no two pair are the same. Heck, rarely are the blanks the same!
To create consistent work it important to have checkpoints that you can refer to along the way. Everybody has their own system. This is what works for me. I have a hard time keeping track of a lot of details so the less thinking I need to do while I'm working the better.
As someone who taught blueprints and shop math (to mostly disinterested welder trainees), I really appreciate the time that you took to lay out all of the cross sections, broken lines, etc.
Hopefully you had a merry Christmas here's to a great new year ahead for you sir. Very nice job explaining it. Very nice way to start to finish project plan to finish. Can't wait to see what the future holds in the new year. Can't wait to see more videos soon. Keep up the great craftsmanship and hard work my friend. Forge on. Keep making. God bless.
Reading a chart is always easier than doing math. I've compared the weight of bar stock to the finished piece and scale loss is negligible for everything I do.
I'm surprised you don't calculate this by volume instead of mass. But, it's a good process. One of my struggles has been figuring out what size material to start with.
Weights charts ( before the internet ) were the only resource available to smiths who wanted a simple way to compare stock sizes. You are right, it all boils down to comparing volumes. The weight is rarely needed in most applications, its just what we had to work with. Also a weight chart in a shop will take more of a beating than any iPad or cellphone.
@@df-intheshop330 I suppose weights are also easier to calculate for round stock. Square and rectangle volumes are super easy, but it does take a touch more math to calculate volumes of round material. Thanks for the videos.
Thank you for another good video. Maybe it's just me, but wouldn't it be simpler to just divide the areas? If you did that, you'd more easily catch the error you made in your second-to-last line. Tossing unnecessary values (bar weight) into the mix only complicates things. At least that's what I'm seeing. Please do keep making these excellent presentations.
Use whatever method makes sense to you. When I started out, weight charts were the only reference available for people like me who can't do simple math in their head. The was no error with the calculations. Part of the reason for forging this sample was to see if I could get away with drawing to the reins as thinly as I had drawn them out.
I guess this channel is for engineers. The math as described made zero sense to me. I thoroughly enjoyed the meticulous nature of the video and process.
This video was an attempt to explain how to estimate stock sizes without getting too complicated. I guess I have some more work to do. The other videos in this series lays out what length to use for each pair of tongs I'm making so you don't need to do the math. This was just for those who are interested.
so great to have you back. You taking the time to do these videos is a real benefit to all of us.

Just love the way that old hammer moves the metal so quick and easy...happy new year to ya.
Awsome again

Good idea to use weight to estimate the amount of material. I think it would be much easier than using volume per length to estimate scale loss too.
Reading a chart is always easier than doing math. I've compared the weight of bar stock to the finished piece and scale loss is negligible for everything I do.
