News:

That nice Mr Ali has a lot of sellers offering Tau 5030 Solenoids, at prices bearing little resemblance to Amazon’s

But, as we don’t do links to the aforementioned … here’s Amazon:

Still hoping to keep this topic on the first page of the list 🙂

I am pleased to report safe delivery of Qty.6 of these solenoids … for a total expenditure of £10.39

It pays to ‘shop around’

Edit: __ I bought the 12v ones [blue coil] … They are nicely made and [with no additional load] operate smoothly on 5v

As source of lamination how about using a Micro wave cooker transformer. As regarding cutting/ milling mains transformer lamination, some years ago I made myself a ‘Growler’ using a large transformer and milled a large VEE in which to place the armature, no problem.

Microwave oven transformers are not the best choice as a a source of lamination material. This is because the normally have a weld run across the windings. They also tend to use cheap materials. If you have a friendy scrap yard you could try them for an industrial transformer.
