Dear Al:
Thanks for your letter of October first. I appreciate your Interest.
I have a cubic unit under construction (about 501 complete) for 5/8 inch on edge anvils f pyrophyllite cube is about .78 inch on edge). Its hydraulic rams have a thrust of 300 tons each. This will give about 65 kbar at full load. This unit la scheduled for completion by April 1976. It is more elaborate, prettier, and better than the Indian unit. Also, the Indian unit only hcs 200 ton hydraulic rams. This new press will have automatic oil pressure control (to + 10 psl). Temperature will be manually sef with SCR control but will not ha«e~automatlc regulation. I do not have all the coa^s together but think it will have to sell for about $106,000.00.
I would recommend a 600 ton press fcr 3/4 inch on edgr anvils. It- would cost about $210,000.00 and require about 18 months for construction.
For 1 inch on edpe anvil*, I would recommend a 1000 tor unit. It would cost around $325,000.00 and require two years for ronstructlon.
On reading your letter 'gain, I think that you were specifying the size of the pyrophyllite cube face and I have been giving the length of the edge on the square faced anvil. If this is the case, a 200 ton press would have 1/2 inch on edge square faced anvila and would use pyrophyllite cubes of 5/8 inch on edge. This machine would cost around $80,000.00 and could be built in about twelve months time.
J. Martin Neil la working with Hewlett-Backard on programmable controls for our presses. They will be available next year a-ad will make it possible to program pressure and temperature in most any desired manner. Such a system will add about $50,000.00 to the cost of a press.
I'm leaving for India on October 17th. Agarwalla has had thr press alnce May but has not had a place to set it up until now. He is supposed to wait for my arrival to assemble it but I think he has been trying to put it together in advance of my coming. Let's hope they havenfc wrecked it.
Best regards.
