Finished up my BIL's PowerStroke charging problem early Saturday morning and had some time left before the wife got home so I started on a personal project that I have been wanting to do ever since I purchased my new lathe back in 2014.
I have been wanting to machine an outboard spider for the lathe spindle. I started by measuring the spindle.
I also noticed that the hole in the cover was not symmetrical with the protruding spindle. The hole was favoring one side more than the other and I needed adequate clearance for the sleeve I was going to machine.
Here you can see where I roughly marked with a Sharpie where I needed to trim.
Here I clamped the cast aluminum cover down to my mill table.
Setting up the boring head to clean up some of the casting flash in the existing hole. I would then merely move the table in the "Y" axis and offset it about .150".
Making progress.
Boring completed.
Cover test fit. The clearance is much more even around the spindle now and ready to accept an outboard spider without coming in contact with the cover.
My rough dimensions of the spider.
As soon as I have some more time in the shop I will start on the spider as I found a piece of thick walled tubing to start with in my scrap bin.
