I had seen and heard of making a fire pit out of a washing machine drum. Well lucky day! The washing machine died!
Please use all safety equipment and caution when working with power tools and sharp materials and fire.
You will need to determine what parts to save and may be different than what I have. However, I present to you an idea you can adapt to your situation if you desire to make your own creation using my idea. The usual W/M tub fire pit is vertical and I thought of going horizontal with complete inclosure.
