The use of power tools isn't necessary to build a LR but it surely does speed things along if properly done. Since installing roller bearing blade guides on my bandsaw, sawing on the line expedites the stock shaping big time. The "infamous" Dremel is maligned by many because of the "oops" that can occur when it's not properly used but for many tasks, to me, it's indispensible. I use a cutter to sink the lock "guts", use 1/2" dia. sandpaper wheels to install the curved portion of a buttplate, rough in a sandcast trigger guard, thin the wall of a cast muzzlecap from the inside and a few other jobs. There must be some skill req'd in a Dremel's use w/o causing damage and observing rotation is the key. An electric hand drill isn't necessary, but again if one is skilled in it's use, can save some time. The only other power tools in my shop are a floor mounted drill press, 12" stationary disk sander and a bench grinder for shaping tools. Some may ask..."Why all the emphasis on saving time since most builders are hobbyists?" On most of the tasks that I use a power tool, especially the Dremel, I do it because these tasks are labor intensive , downright tedious and really stretch my patience. Overall, I estimate that 90% of my hours to complete a LR are for using hand tools so I still consider my LRs "hand built".....Fred
