I have used the original NEY machine for many years now and this
device has not let me down. In fact, in a difficult sitution between
moving and resetting the shop, I was forced to use it in my home
driveway. With the “almost self balancing” shell/protective rim" and
the base, the machine was set on a board between two saw horses and
worked fine with a little cinderblock weight on the sawhorses.
Failures with this NEY machine are almost always attributible to my
technique and not the machine. Unless you want to go for much higher
priced “do it all” machines set up for mass production, I don’t see
you going wrong with the NEY. It has served me well.
I have used firebrick and fiber lined burnout ovens. The NEY is a
fiber lined, or a more uniform formed high heat surface with the
heating elementd enclosed in the fiber material. This over has also
worked quite well for me. No probs. The lining is cracked a couple
of places after many, many years of work but all does well and not a
repair needed yet. I got this equipment several years ago, not sure
when but soon after it was first introduced on the market. If the
quality is the same as before, you are a go for Ney. If the quality
is better now, it is more of a go, regardless of the price
differentials with other brands. The compact “ready to go” aspect
of the Ney caster is to be appreciated, esspecially if you cannot
always have a permanent setup for your work.
This is my experience with the equipment you mentioned. I do hope it
helps in some measure.
