DIY heater for a Lyman 450??

I have read in a WTB thread prople talking about making their own heater for the lyman lube sizer. Any one here "been there done that" if so how?? I'm always looking for cheap but safe stuff!

1/4 inch scrap Aluminum plate under the sizer-------- FREE
Old cloths iron from a tag sale ---------------------------$2.00
Cheap enough ??

The Iron has all the heat control you need and works great.

Old heat gun or hair dryer, heat from a light bulb.
Use softer lube.

any other idea's? i have same luber and looking to make my own heater for it....

I use a 100-Watt bulb in a clamp-on, goose-neck lamp that is secured next to the 4500. I cover the 4500 and lamp with aluminum foil till the lube is to temperature than remove it and turn the lamp off. If the lube cools too much, I turn the lamp back on.

I just finished adding a heater to my 450. Elsewhere (can't remember which forum?) I saw a suggestion to use an automotive oil pan heater. I found a 2 inch by 5 inch 50 watt heater for $11 at Amazon and had some 1 inch thick aluminum plate that I made the heater plate from. I have access to a mill so I cut a channel to put the pan heater in. if I had had some 0.5 inch plate laying around I would have used that and a piece of 2 by 6 wood that I would have cut the channel in it would have worked just as well.
I just finished cleaning out the old Alox 50/50 lube that was in 450 and loading in the hard lube. After trying the heater the first time I found that the base of my 450 was rough enough that I wasn't getting good heat transfer to the lube/sizer so I added some heat sink compound between the heater plate and the 450 and added a lamp dimmer to adjust heater output. Now the plate is at about 135 F the body of the 450 is at about 125 F and the sizer die is about 122 F at 2/3 setting on the dimmer.
