Bench Rammer -- Alternate use
Pros: I'm using this as a hand-held tamper to pack soil back under foundation footers that we have tunneled under to bring in electrical and water lines. Easy to use in a horizontal position when kneeling or lying on my side, and much faster and less tiring than trying to use a manual tamper. Getting good compaction yet isn't overly loud. Appears well built and doesn't use a ton of air (I'm running a 1/4" 100 ft line to a 25 gallon surge tank near the tool and my 5 hp compressor and the surge tank are able to keep up with intermittent use (shovel in some dirt, tamp, shovel etc) Works well in a crawl space since it is so compact. Small size of the tamper foot means I don't have to carve out a huge tunnel (A full sized air tamper would require a much larger excavation so that one could fit the tamper foot back under the footer.)
Cons: CFM requirement means that you aren't going to run this on a small framing / pneumatic nailer compressor.
