You can use a 1lb disposable propane tank with your Bond model 67836 fire pit if you get the right adapter. I've done this with my own camplux fire pit, and it works fine for short sessions. The key is to ensure the adapter is tightly secured and there are no leaks. However, keep in mind that a 1lb tank won't last long, maybe an hour or two at most, depending on the flame size. It’s handy for portability and quick use but not ideal for longer gatherings. Always keep a spare tank and check for leaks before lighting.
