I'm still not entirely sure this is a good idea though, seems like a low-temp oven for the whole tbolt would be better if you want thermal stability.
Precisely because it is not clear that holding the backplate of a Tbolt at a constant temperature is the best way to keep the interior of its crystal oven at the most constant temperature (which is the ultimate goal), I mounted mine on thermally insulating standoffs in a cast aluminum box with about 1" of clearance on all sides, and control the air temperature inside the cast box.
For another Tbolt mounted similarly, I control the surface temperature of the cast box, which seems to work equally well.
In both cases, I adjust the controller for whatever measured temperature produces a Tbolt internal temperature reading (via the Tbolt's DS1620) of about 45C -- safely above any ambient temperature to which the mounted units will be exposed, to avoid the need for active cooling (Peltier, etc.), but not excessively so, to keep the internal electronics as cool as is practicable.
