Buy a regular Tanaka Powerhead...not the Nils head....cut bend out of handle on Lazer....jam a 1/2" threaded rod into chuck on powerhead...add a little weld...you have instant (faster than Nils) powerdrill...we have been building em this way very near thirty years....you can have any good machine shop build you one...had a friend have a couple made for an Echo drill, was not cheap....
