For 16ga steel, I would recommend a 24 TPI blade or higher. I’m not sure what blade the school shop has, but the tooth spacing felt a bit coarse for the job in the video. You want at least two or more teeth to make contact within the thickness cross section of the material to avoid breaking the teeth off your blades. Smoother cut edges are achieved with a finer tooth bade with slower material feed rates. And your blade speed is going to be around 300-150 Ft/min. consult your bandsaws literature for recommendations. Blade composition is usually a high-speed steel, or better yet a Bi-metal. I’ve found Starrett or Lennox make pretty good blades, but I’m sure there are other competitive brands that make good blades too.
In middle school shop class in the mid 70’s, we made dust pans from galvanized sheet metal with riveted (not pop) connections. I made 4 of them, and every single one is still used today! It’s a shame that in most parts of the US, shop classes are ancient history. The skills I learned in school shop laid a path for me that’s provided a very good life! At 61 years old, and looking back over all those years, there was much greater value in the shop than any other class I took! God bless you Sir for keeping the dream alive!
I made one of these in 1974. I spot welded it together. We only had arc and spot. :) Part of our requirements was to spray paint the toolbox to demonstrate that process. I used it for years, gave it to my dad, and now I have it back, still useful. Fun to see this project again. thanks
Perfect processing sheet metal bending demo with precision machines and tools. Jointings you have shown tig welding and spot welding.could have shown revet joints and lap bend joint also.All jts in one.
Those wire speeds differ by a lot given that the rest of the weld parameters are about the same. I wonder if they are in different units, or perhaps not units at all, just numbers that are meaningless outside of the context of the particular welder. If they differed by a factor of 25 I could see them being inches vs mm per minute but they differ by a factor of about 7.
I teach a adult welding class and use this type of project to get my students something they can say i built that. only a few week class couple of hours per.
Great video! The only gripe I had with the school I went to for fabrication and welding is that we never made anything useful considering the amount of shop time at hand. I hope your students appreciate the work you're putting into this. It's much easier for a teacher to have someone churn out endless lap welds than it is to teach something practical
nice video--nice project. Question: What blade are you using on bandsaw (ie TPI) and what speed?

Great easy to follow instructions.

Thank you for this perfectly detailed presentation 👍👍😎👍👍
Nice!

What part of the US do you teach welding class?
great

Didn't he put the cutting disc on the wrong way?
