pryometers

Hi magnum44!

Do you want to use them for heat treating? If yes, stay away from them. A friend of mine works as an engineer in the foundry institute of the University of Aachen and he told me they call them pyrometers "lying telescopes". Guess why. He sais that all the experienced workers do a much better job guessing the temperature by looking at the glowing steel than the pyrometers.

Just my 2 pfennig.

If i were you i would call paul bos and ask him about his equipment, he has very accurate gages. His number is in the back of every Knife Annual, although its easiest to catch him at home, he rarely answers the phone during the day, busy i guess..

Pyrometers are very expensive and must be recalibrated on a regular schedule to insure accurracy. They are very preceise on the order of +/- 5 degrees or so.
Check out temperature crayons( i can't think of the real name right now,havan't had coffee yet) This are "crayons" that melt at a specific temp.Touch a piece of hot metal,if crayon melts go to next higher one in series. I think BROWNELL"S GUNSMITHING CATALOG has them.You can also try one of the big industrial supply houses like MCMASTER_CARR etc.

These are brand named TEMPILSTICKS as I remember it. Short for TEMPerature ILlustrating STICKS ?
 
Almost any Pottery supply company will have pyrometers. They are pricey, but give you an idea of the efficiency of your forge. Th last one I bought was about $80.00. I got mine at Seattle Pottery, 1-800-522-1975.

thanks guys but i need it to see if the forge can obtain melting temp, not for heat treating, rob simonich does my heat treating.
i'm not using this forge for knifemaking, instead for casting iron and doing ironwork.
 
Have you tried just setting it on a reducing atmosphere, and putting iron filings in it? It's tough to beat the results of an experiment for working data. What fuel does this one use?

This is way out of my area of so called expertise, but if what you wish is an idea of the maximum temp of a forge, I recall that potters use cones which melt at different temps, and when the correct one melts, they know to turn off the heat to the kiln. If there are any potters in your area, you might ask them. Walt
 
thanks walt, but i don't know any potters in the area. bruce helped me in finding a pyrometer. thanks bruce.
