rob I too thought the cost compared to a load of drills but then broke a specific drill, later at night, all suppliers closed etc, etc. Three days cursing and a trip to suppliers later... For the ease of being able to say "fixed it" it was worth the cost. Plus it was a" a lovely reminder of our holiday my love" rather than the usual holiday tat ! :beer: Devious - who me??? :thumbup: Only you can make that decision, I've no regrets ( apart from not getting the larger collet obviously).

Uuh...ordered 750 model from Amazon, "free delivery" my ass, delivery + all other expences added up 60 real money over that 139$ price tag. Got it and first looks is a bit disapointing....looks chinese made, lot of critical parts are plastic etc. but have to try it out to see how it performs. http://screwdrivers.viabloga.com/news/drill-doctor-internal-mechanism-220v-convertion Looks like a cheap DC motor and rectifier. MFG is coming at it at a little obtuse angle, looks like marketing talk to me. http://www.drilldoctor.com/faq I live outside North America - can I use my Work Sharp Sharpener with an adapter? A transformer (not a complete power supply), plugged into single phase 230v, can drop the voltage to the 115v range, but doesn’t account for the difference from US frequency at 60 Hz and Internationally at 50 Hz and may not regulate the voltage or provide sufficient amperage well depending on the quality of the device. Running on 50 Hz puts a greater strain on the motor, so while the correct voltage may be supplied to the unit, the frequency isn’t correct to get full performance (reduced power = lower efficiency = extra heat = destroyed unit). The voltage may also not be precise, out of a transformer and the 115v motors are designed to run in a specific range. High or low voltage will likely cause failures. I did dig up my old 220/115 VAC tranny, but it spits out a bit too much voltage and it is that old that I'm going to retire it, checked it inside and the euro-plug is bit funny, insulation would not pass moderns standards etc....Don't like. Expecteng it to perform impecably, marketing is that massive that if ti produces nothing less than perfectly sharpened drills in seconds I'll be very disapointed. Pekka |

Pekka, What I do is to be very careful when "aligning" the bit with the "snap down leaves." Getting that wrong can easily destroy your bit! I place the "bit" in the "chuck" so that it is a "slip fit loose." Then, retracting the "leaves," insert the "chuck" and bit into the "alignment guide" and release the "leaves" -- and (light finger pressure) twist the bit to make sure that the "leaves" have a good hold on the bit. Then I tighten the "chuck" (with finger pressure to mate the tip of the bit to the metal "depth setter"). With that as "care," everything seems to work out fine. |

Thank you Lew, I will get 230/115 VAC transformer tomorow (If we can me schedules co incidence after the work). I did try 14 mm and 6,5 mm OD drill chucking and alignind to it. I have 750 model. 1) There is stop screw (MTO!) I adjusted it all in - minimum material removal...that looks like it affects on the aligment too.... 2) Is the aligment mechanism designed to work with old fashion drills with complete heel? Most of my drills have the heel pretty much cut out. Question: How much interaction this "aligment" and depthing adjustment (MTO) have interaction? Is it relevat to sharpening? Probbaly just have to try out some less worn out drills and just to polish a minimum amount to see how does it conforms with original drill's sharpening. Thnak you, Pekka |
