Tube Frame Safety / Design

[JimmieD]

Hi guys!

I don't want to post any details at all regarding a method for inductance, or as mentioned more correctly, resistance heating, due to personal liability issues, sorry. Just brought it up as a possibility for those who are able.

And regarding the frame and thinking wood design while designing, that's a generalization of planning distribution of loads, that if it would work in wood it will work in steel to have sufficient strength. Speaking of tension and compression loading.

Anyways, I was just tossing it all out there for chit-chat so apologies if it all sounded like a bunch of chit, but we did chat!

Have a GREAT week!

If you do this, please take video, I'd love to see it.  How do you control the cooling rate afterwards (which is critical for normalizing)?  How do you control max temperature?

In your description, I don't think this would actually be called induction heating, but more likely resistance heating, which is much different.

Induction heating is very common in the heat treating industry.  Are you saying this type of normalizing procedure (let's call it the Frankenstein method) is common for frame builders?   

It sounds like he is basically taking an oven element and wrappping it around the chassis, rather than passing the current through the chassis. You would control the max temp and cooldown thre same way as you would with an oven - thermostatic control of the amperage.

Edit: Whoops, he did mean resistance heat treating. Oh well, same control methods I guess?

i don't think you understand heat treating basics guys.
