[modeleng] Re: Replacable Tips

Like Jesse, I am a survivor from the early dark ages!

 I was given my first lathe during the War (despite rumours, NOT the
 Crimean!) and this came equipped with a set of carbon steel lathe tools.
 High-speed tool bits were difficult to acquire (There was a war on!).

 I have never been an expert tool grinder and would rather spend my time
 making things - so unlike the rest of my bretheren in this List, I
 enthusiastically embraced the advent of the disposable carbide tip.    I
 have an elderly Emco V10 Maximat, which has a higher range of speeds than
 the Myford.
I find that I get the best results from the carbide tips, turning at high
 speeds whilst taking relatively small cuts.

 Harking back to those old days, fractional hp motors were very expensive,
 and factories and workshops ran off one large motor, through a maze of
of shafting, and 'loose-and-fast' pulleys and falt belts.  This would make a
 present health-and-safety inspector faint with shock!

 Cheers!    Hubert
