I really liked browsing through your website. The furnace was nice! I have the holy fear working with propane, so I ask; Did you ever consider using a large TIG welder to create a small Arc oven? The Duty cycle on a Transformer Miller Tig seems to be good enough. or Do you know of someone who does

Interesting Kirk, Thanks for the ideas. Considering that new "industrial" Nema 12 type encoders can easily hit $500-600 each this is something to think about. Dave On 3/5/2010 2:08 PM, Kirk Wallace wrote: > On Fri, 2010-03-05 at 10:23 -0500, Dave wrote: > >> Like you guys, I'm interested i

Like you guys, I'm interested in using some of these inexpensive encoders. Compared to industrial units, they are a fraction of the price. The casing and wiring is obviously not "industrial" Nema 12 etc, in nature - no oilproof military connector on the side of the encoder and no bearings...
