Hi Guys
Guess most of U will be getting ready for Festivities for which we can take the occasion to wish U and Your Families all the best.
Most of U may be aware of my purchase of this Walter Milling Cutter, Hogger - I call it, quite a while ago.
Due it having a 25 mm Shank, I was advised at that time to turn the Diameter down to my required 19-20 mm's. To get that done correctly, we had mutually agreed that it would obviously have to be done on a Four Jaw Chuck.
Well we tried that month's ago and it literally drove us nuts as we just could not get that right. If it clocked perfect at the Jaw end then the Tailstock reading was cockeyed. If the Tailstock end was rectified then the reading at the Jaw end was off-beat.
It was crazy. We even argued with the Supplier thinking that he let us have a reject part which we got off Flea Bay.
Cut a long story short, we tried again yesterday and battled for another hour or two, getting the readings close, but not perfect to our satisfaction. Even the Wife suggested we just leave the problem alone for a while, as we were getting no where with this.
It then dawned on me today that seeing this is a Three Insert Holder and a Four Jaw is never going to grasp the front face evenly, why not try the Three Jaw Chuck.
And voila, it worked like a charm.
As a precaution we did clock both ends and the readings were a couple Hundredth of a Millimetre off. That was more than ample enough accuracy for this sort of a cutter.
Although it has a hardened shank, Turning the interrupted cuts ( Weldon Shank) was a breeze. Methinks we achieved a fairly decent finish.
We ran the cutter on the Mill just to eyeball concentricity, and she ran flawless.
Lesson for the day, the FOUR JAW is NOT always right for the Job - as it's made out to be.
Guess most of You Guru's will disagree, but for now, I know from experience.
Like always, there's no good story ending without pics. Well we have attached lots to eyeball. We reckon we can live with the Chuck Jaw markings on the Cutter Face, which we will try and avoid, next time - LORD Willing.
Thanks for reading, if U got thus far
Stay safe and Take Care
