i am from doncaster looking for others in area who i can chat with pick up some tips, i am considering making a gem faceting machine, used to cut and polish stones, at the mo still locating plans and different designs, there are a few they all mostly work on the same principle, apart from those with more digital extras, its good to be able to look on here to get inspiration. if there are any locals or any shows coming up , it would be nice to know

hello thanks for your interest, , john and bob. firstly my initial concept was to use this system so as to not be purchasing oxygen refills, all i wanted was to do some welding ,brazing without being tied to consumables. so i looked at how, acetylene is produced, and then oxygen, i kind of bumped into it while researching, the design is not my own in fact it is used in a few areas, one being oxygen concentrators used for the medical industry, for people who need purer air , oxygen than the norm, there are also uses by the military, and it is used to produce nitrogen and oxygen, in the nitrogen process oxygen is the waste product with argon and other trace gases, simple process . compressed air is pumped through a zeolite, molecular sieve, to about 120 p.s.i. oxygen or nitrogen depending on your sieve is separated from the air mix, , you can harness either or both,. there is a brilliant design in (Instructables, by imsmoother) full assembly and materials it uses 40 kilograms of molecular sieve, 20 in each reservoir. the creator of this particular model uses it to harness nitrogen, he then goes on and liquidises the nitrogen, very clever, does it on his driveway, however inititialy i want one . i am interested in modifying this design, using smaller materials, it would make more cost effective. so any thoughts would be appreciated, i have just located a supplier for the molecular sieve in the uk, took me ages to find. heres a picture

hi i am also in the process of building a furnace, the main one is to be out of a stainless steel beer keg, the refractory i will be ordering is from artisan foundry supplies. artisan foundry .co.uk, its tri-mor monolithics up to1700c, can melt iron if using a waste oil burner, similar to collin pecks design, , the price for the refractory is£41.99 for 25kg. i looked at the electric design however not so good with electrics.

thankyou for all the replys most appreciated, i am in doncaster south yorkshire,, i will be checking through your suggestions

hi everyone am new here but i feel i am in the correct place. to start with, i am building a furnace to melt metal, i needed to do some welding, so i decided to build my own oxygen absorbtion machine. when complete should be able to process compressed air to oxygen actually its concentrated oxygen. with the pressure swing system, it separates, oxygen and nitrogen, and the trace gases, it can process nitrogen to 98% and above using a molecular zeolite filter, called 13 x, . heres were i could use some wise knowledge, i need some flanges for my machine, i have been all on the net , even today t a local fabricater not small rather large firm however. i thought to myself i could make these myself if i had the tools,(i am a carpenter by trade). so is there anyone on here who can make these flanges or do you reccomend someone. heres the spec.

8"150# raised-face slip on flange i need 2 of these

8"150#raised-face blind flange. thankyou for taking you time to read through.
