Just picked up on this thread while googling Pehaka. Maybe a little late for comments, but here's a few that I hope may help you on your project. #1- the blade guides are DoAll style, different thickness slotted blocks (to accommodate different blade widths) with a 45 deg. bevel at the end. Not sure if they'll fit but it's sure worth a try. #2- to power the 3ph. motor you could go with a Variable Frequency Drive with a single ph. input and three ph. output. You could then use the Freq. drive to control motor speed. I used this setup on a 14" band saw and it works great. Good luck on your project, Jerry
