Title: one size does not fit all
Review: seems to be an issue with these units from reviews I've read - need to determine the shaft width - manufacturer needs to specific what brands the unit fits. Found the process confusing - returned unit at my expense, and not too happy about that. Spent extra to buy a well engineered tool - it appeared to be just that, but if it doesn't fit it doesn't matter - ended up with the 'saw brand' at a 1/4th of the price and not nearly as well made..
