We decided to fabricate our own false bottom. Basically I just ordered a 24″ x 24″ stainless perforated sheet with 0.09375″ holes with a 0.15625″ stagger. After I climbed inside the kettle my wife placed the perforated sheet on top and I used a sharpie to trace the shape of the kettle. Then I cut out the circle with my angle grinder.

The handle and the leg supports will be made out of 0.125″ x 0.75″ stainless flat bar and bent into shape. I cut each support/handle at 10″ and make marks where I want the bend. Placing the flat bar in my vice at the appropriate mark I hit it with a hammer until it has a 90 degree bend.
