GM-70 Iron Works, Metal Chassis Tooling …

P1120025 b2

OK, So I am not quite yet sure how the intricate fine details of the schematic shall work out, but in the so called meantime, I guess that having found a nice can of Hammerite paint, and using a sunny long weekend, I came up with the idea to take the saute, rusty iron bits and pieces that came along with the whole set and try to make them less rusty looking …

A bit of rust cleaning here, a bit of iron grinding and brushing there, and then, finally, put some paint on the stuff.  Why Hammerite ?

Because it is the only reasonable paint that I know of that can be applied on rusty surfaces. Any other solution would require at least two different types of cans: a). an anti-corrosive underlayer paint and b) the finishing paint.  Here I have it wash-and-go. 2-in-1.

And besides, I had a can readily available, partially used and abandoned long since, aging since three years in the cellar. If I would not use it for this project, most probably I would be throwing it out to the trash within the next five years or so. What a waste.  Since it is available, … Go for it!.

So I did.

And this is what I came up with.  Mind you, very old paint, and partially with lumps, papules, but with a bit of brush work – I managed to even it out. Sort of. Anyways, this is just the preliminary first layer.  Finishes will come after some possible additional tooling.

At least it is not rusting any more. A higher spouse approval factor.

On the pictures below, you see the 10 kg or iron representing the left channel, and 10 kg of iron representing the right channel.

Indeed, this is a “military” version of DIY.  The hammer green blends in well with the sheer kilograms.  But the toroids will definitely be refrained from shedding electromagnetic havoc.

These sturdy, 3mm thick steel walls will strongly discourage the transformers from spreading stray magnetic fields (the power supply ones).  At the same time, the interstages, the chokes and the output transformers will be somewhat protected from picking up stray magnetic fields.

This does actually come at a price of the sheer kilograms, though.

Simple and Stupid … Brutal Force – in Action !
