I developed a prototype tumbler in early 2016 and shall attempt to complete the project in early 2017. I intend to produce plans, including a formal video, as a fundraiser for nonprofit smithing associations. The tumbler is simple and low cost to build, fairly quiet, large and effective. The noise level in the video is greater than that in reality. First step is to pickle the forged work in food-grade citric acid for 12 to 24 hours and then to neutralize the acid upon the work in a baking soda solution. The pickling causes the forge scale to become dust like. A rubber mat lines the interior of the 55 gallon drum and its two ends. Media to date has been 'drainage rock' from Lowe's; the rock is deeper than that shown in the photo. Tests have been both dry and wet tumbling. The photo of bent nails show the results after just 20 minutes of tumbling. Fontana_Forge_Tumbler_Video_01-16.m4v
Hi, I have been making hooks ,and it takes as long to wire wheel them and wax them as it does to forge them. So I made this 5 gal.bucket as my tumbler. My question is now, how do I use it? What type of media should I use to descale? Should the bucket be 1/2 full or 3/4 full of media? Also, should I put some thin cuts in the bucket to let the dust out? Thanks for any help you can give me. Keith
