I found an old Kitchen-Aid stand mixer and adapted it to the purpose. It's still the old "stainless steel bowl and heat gun" method, but now it's essentially automated. I go out to start the process (2 minutes), then come back about 20 minutes later to watch the finish. I do about a week and a half's worth at a time. Simple, effective, and not worth the upgrade to something "better."
