Re: Trailer Security

What woke me up was the day my next door neighbor who has a ramp truck and I went up on the interstate to pick up a friends enclosed two place snowmobile trailer that lost a wheel and hub. A local policeman showed up, blue lights on, asked if we needed help and never asked for any identification or ...

Re: Trailer Security

The tracker that I have sends me a message once a day telling me that it is in my driveway, unless I am on the road with it. But, If I need to, theft, I can call the tracker company and they will switch to continuous mode. Shortens the battery life, but if it gets my equipment back, it will be worth...

Re: New Jersey: Cook Tool & Machine

USPS has gotten a lot better a tracking in the past 5 years or so. Before that, the package would be on my doorstep and their tracking would still say it was in the midwest somewhere. Now, it seems to be spot on and detailed.

Re: What is the difference.....

When I started at the foundry, we had 5 mg sets for melting. Two of which I hated to work on, one was a 300kw, and the other 200kw Brown Boveris, 4160vac, 60Hz in and 3000vac out at 1500Hz, both water cooled. Did I mention that one of them leaked water? Shortly after I had started, the 300Kw unit ha...

Re: What is the difference.....

A motor-generator is a electric Motor driving a generator. Such as Harolds MG melter, the motor end is 240vac 3 phase, turning a generator that is putting out 3000 VAC at 3kHz, Harold correct me if I am wrong. This is quite often all as one unit. However, I have one here that is 480VAC, 60Hz, 3 phas...

Re: One man's insanity---the story of an induction furnace

One way to look at your furnace; If it was an older ham radio, you have to tune the transmitter to the antenna. This is what the output stage, with the capacitors, of your induction is; the tuning stage.

Re: One man's insanity---the story of an induction furnace

An induction furnace is looked upon as a transformer with a shunted secondary. It relies on eddy currents for not only melting, but stirring action, which is rather abrupt, and a good thing, as that ensures a homogeneous heat. I was always told by Inductotherm guys that it is a shorted secondary, no...

Re: One man's insanity---the story of an induction furnace

"I've been aware of the idea that a "heel" is needed when firing the furnace. This heel provides a large enough mass for rapid heating, and that makes sense, but by starting with a load of small pieces, you get heating, it's just a lot slower. Is that correct?" The "heel" is made after the first mel...

Re: One man's insanity---the story of an induction furnace

Fantastic! Congratulations Harold and Patio! This has been a long and expensive project and to have this unit start and run with no problems is great! I wish I could have helped more. What you experienced with the coupling between the load and the furnace is normal. In the foundry, to start a cold f...

Re: NJ/NYC/LI Machinery Movers

Speaking of the riggers with insurance, the place where my wife works had a CNC mill brought in by the riggers. It got dropped hard, mistakes happen and nobody got hurt. Shortly there after, they brought in a brand new replacement.
