With the PTC Heating Element arrived, it was time for some metal bashing.
Actually, it briefly got a bit more "high tech" that that. I needed to try and replicate the Elma Heater, based upon what the Elma spare part heater looks like from catalogue pictures. A quick estimation on my part seemed to indicate a mounting plate size of around 90mm diameter (the element being 85mm on it's long side). Where to sort it from?
A quick conversation with an old work-mate turned up the opportunity for a catch-up and a bit of "metal bashing" for the cost of a light lunch.
A bit of mild steel around 1.5mm think was run through his laser/plasma cutter in no time and I had my mounting plate. Once back home, it was drilled to attach the heating element. So that job done, now to mount it in the machine.
In my opinion, it's not a bad replication of the original Elma spare part and I cannot imagine that it would be any less efficient.
SO - if you cannot get hold of the Elma Heating element, all you need is a relatively cheap PTC Heating element, and a good mate with around £35,000's worth of plasma cutter!
I have a french four glass clock that has a mercury pendulum, I have noticed that the tubes where placed upside down I have placed them the right way up, how long does it take for the mercury to run to the bottom of the tubes because its not exactly free running stuff, I think it would be pointless trying to regulate the clock until it has is this correct ?
You really cannot skimp on a watch fitting glass tool. You need to have one that you can trust and get the repair done without worrying about is it going to work. The cheap tools will not do a good job, they do not fit properly, and they break, not lined up and will not last long. Buy the best and it will last a lifetime. I had many including the Robur. It is necessary have tool.
