Proper Temp For Adjusting Propionate Frames Without Causing Shrinkage?

[Lelarep]

My reference book says the temp. for properly adjusting propionate frames, without causing shrinkage of the frame, is 67 degrees Celsius.

Is this correct? I wanted to make sure my references were right before I attempt to do so for a customer and destroy their frame. Never worked a propionate frame before, any tidbits of wisdom from our more experienced members?

Our hot air machine is in Fahrenheit, and can be adjusted in 5 degree increments, so I think I'll use 155, given the conversion from Celsius sort of falls right in-between 150 and 155.

Seriously, absolutely no love on this, at all?

This resource also agrees with yours.

i just really really hate propionate frames :(

Temp was right, but apparently my pressure was too much, it left a "crease" in the frame. Sigh. That's the first, and last, propionate frame I will try to adjust.
