After quiet a few distractions it is finished....
Ok... there is a back story. When the boys (Jacob, Ben, Joe) and I use the mill it feels like it takes 3 hands to change the R8 collet and accessories sometimes. There is no "spindle brake" or "spindle lock" on this mill. After a bit of searching it appears that Grizzly and LittleMachineShop.com both sell after market spindle locks.
As much as I love to buy parts from Carl at LittleMachineShop.com I do get tired of sending out the money. I figured that since I am man that owns tools (Mill, Lathe, etc) I should be able to make one of these.
I purchased a scrap piece of 6061 aluminum from a metal retailer in the Minneapolis area. It is 2.5"x5"x5" weighing in at 6 pounds.
Since I don't like to start small my first project in the new lathe is pretty complex. I have not even made chips on this lathe until now. --As they say "Go Big or Go Home!"
That 6 pound block now ways about 1 pound. The total cost of parts for this project was about $18. There is probably 8 hours of labor in this project between setting up new machines and tools in addition to taking pictures and showing Ben how to setup the various operations.
It was a pretty cool project and I am very happy especially given the complexity and the number of operations. It works VERY well.
This mill is a G0759 which is the same as the G0704+DRO or a BF20 or a Super X3.
