    Hello all,

    I picked this up a month or so ago, and I'm starting to get it prepped to install in my small shop. I have reviewed tons of old posts for info. All of it awesome and much appreciated. Please forgive me if this may be redundant to some.
    1. Am I correct in assuming I'm missing a bottom plate? schematic shows another plate.
    2. Looking for recommendations for adding back plate insulation. What have people had luck with? I'd like to possible use fire brick.
    3. Is there a way to do a 'lazy man's rebuild" by simply sealing inside seams without taking it apart? Furnace cement possibly?

    Cheers guys!
    Ken

    Yes, it's missing the bottom plate. Try to locate one from a scrapped 602. In a pinch you could make a bed out of firebrick, but at a loss of firebox capacity. I added a rear burnplate by making a cardboad template, then having a friend plasma cut one out of some 3/16" steel. I bolted it to the back with four 10-24 screws using a nut in between the plate and stove back to create an air space. This definitely reduced the heat on the back which is a common place for cracking if the stove overfires.

    Rebuilding these stoves is super simple. There is no reason not to do it right. It took me about 2.5 hrs and that included drilling out and retapping a couple broken bolts.

    Did you still and tap your backplate to the back of the stove, or just lean it in there?

    I drilled clearance holes in the back for the 10-24 screws and thru-bolted with another nut on the outside to hold the shield firmly in place.

    There is a bottom plate with wavy lines cast into it at the base of the firebox.

    The bottom (underneath the plate) also has those cast squiggles, but only 2 and some sort of mineral insulation between them. It looks like the insulation was scraped out on the OPs stove. The bottom plate that goes on top of this has 4 squiggles and looks more finished.

    It should have more protection. The sand layer is recommended to go on top of the bottom plate.
