Mark Parkinson---Hi--- hay thanks for the link and if you could Please ---put up the other links up--- i will go for a look see---

Glenn Hi and Thank you for that info most interesting I understood it worked the same way a diver gets the bends ... the nitrogen in the blood boils when it is depressurized to fast the diver then has a gas in there blood and the Oxygen boiled later or at a lower pressuer ---but that's just me nutting it out --- himm wonder what the Absorption material is Zorbox marketed a small plant --but thet no longer doing it

Hi I am interested to find out about a PSA - Pressure Swing Absorption ---Oxygen Generator the ones for Generateing Oxygen for use in a small engineering shops ----gas welding of panil steel mostly for oxy-acetelyne welding all thow having enouth for Oxy propane cutting--- Would be a good thing to have ---I am interested in the cost of a P.S.A to do that type of work ---IF any one knows the Prices of these things that would be neet ---- Thank you for you time----

Spark Eroding--- This works by useing spark erosion...

I was serprised at how well Jiff worked ok a don't know how good it was for the cutting tool / drill

ApprenticeMan; Hi thanks yer i well neeb all the help i can get

Hi ...I have stated to make jaws for some vices i am rebuilding... making them from some old files I have Annealed in lime then cut drilled and fitted to the Vice.... I need to know what the best way and or Temperature to temper them at ??? Also some one said that this can be done in some type of mud dos any one know about this technique? Thanks for any info

Hi --i would get a drill press some old drill bits and try out your cutting oil that you have and see what works best....

I have just found this site i have an interest in blacksmithing as part of my hobby in engineering wish every one well
