I finally got around to making a heater for my lubrisizer.
It's just an aluminum plate that the lubrisizer bolts to. Actually, it's two pieces of plate, just because I didn't have a single piece wide enough. The plate is drilled & countersunk for drywall screws to attach to the reloading bench, plus is is drilled & tapped for bolts to attach the lubrisizer.
An iron is placed on the plate and set on low heat for about 30 minutes before the lubrisizer is used. It takes that long for everything to get warm, but once it does, the iron can be turned to the lowest setting.
If you leave it unattended for an hour, you may return to find liquified lube dripping out. Don't ask me how I know that.
Total cash required = $0.00. The aluminum works nicely but you could use steel, too.
