How do I get this widget made (a small rectangular bit of 1.6mm mild steel)

I have a notion that you need soft iron if you want to do magnetic stuff. I could be wrong but hot rolled sounds a lot more appropriate than gauge plate. Sure cuts easier.

If you need this job looking at its pretty straight forward. Lots of very elaborate and overkill ways have been suggested to make this part and its really very simple and is not a job that warrants fancy machining methods to produce at a cost, A lot that have been suggested will cost you a small fortune. It's some 1/16 cold rolled sheet stripped up and machined to a size............... that's all it is really. If you need a super finish on the visible edge then there are methods that are available to achieve that finish without fancy and expensive grinding.

If I can be of any help please feel free to contact me.


Kind regards,

As it transpires, since my initial post, I've now established that I probably need the part to be something like 430fr stainless (on account it has higher electrical resistivity, therefore less eddy currents - and eddy current heat seems to be more of a problem than I first realised - especially at higher frequencies) ....430fr also resists corrosion (which was something else that was troubling me)...so right now, I'm on another quest to find a 430fr supplier that won't want me to buy 0.5 tons as a minimum order! (& the early indications are that it's likely to end in a cul-de-sac, because 430fr seems to be mainly supplied in rod form ...& in large quantities - it's a wonder anything new gets to market made by the small guy!)

Thanks to all who contributed ...& Scott, I'll definitely be in touch when I need such work done.
