We're rolling on this again... I know, it's been a while but, these are my "leisure" projects -and it's been too hot/uncomfortable lately...
Here we're surfacing the plates to be used for the base. I'm not going to recycle the old one as I wish to keep it intact.
The mill is trammed nicely and is giving almost a blanchard grind look. There are several of these to do and the new vise (
http://www.machinetoolonline.com/VisesHighPrecision.html ) is doing great! I've checked the width of each at 1" from from the corners and total variation is staying well within 1 thou. -Would not have been possible with my old vise -no way, no way at all!
That's a 3", 5 insert cutter spinning about 800 RPM. First DoC was just 5 thou to take the scale off. Next evened it out 10 thou then, I took a skim pass not changing the DoC. No coolant today -not needed for baby cuts like this and plate was easy to handle meaning temperatures were probably around 110 degrees.
More later... I'll be working on this all day to catch-up...
(Plate looks really blue because we have a beautiful blue sky today. The grind marks in the plate are nowhere near as ugly as they look on camera).
