Rate of advance on 1.5 inch piece

[Stephen Richard]

You are trying something difficut.

I suggest (in degrees F)

11/hr to 510 no soak, 17/hr to 1000.  Start checking from about 600, as there will be a lot of heat work put into the piece by this time.  It might even be tack fused at a lower temperature.

Anneal cool should be on a slower schedule than previously, as the tacked parts will try to pull away from the big block.

So I suggest 3.5 days for heat up and 2 days for cool down to be sure everything is secure.

Is there another way you can do this?
