RFQ - custom 43mm spindle mount

[HankMcSpank]

Hi Ian,

Good spot with the mounting bolts., I'm liking what you've done...




In this fine forums' opinion, would 25mm be about right for such a mount? (just checked the spec 4.2kg of my spindle ....yikes, no wonder my CNC Z plane stepper was struggling on my homemade machine!). Also, I need that amount of 'throw' from the back of the mount to the spindle centre (because the upper portion of Proxxon spindle measures about 82mm diameter) ...just wondering about the mount's weight here ....would it be worth removing some material out of that long back edge (a recess?!) to remove some weight from the mount?

Oh btw...

. The 71mm pitch isnt a problem, you can just mill a drilling jig to get it spot on if you really want to.

That's why I like this place so much ...to my non engineering background, this is pure enlightenment! (ie you've solved a problem not just for this, but for all those other "hmm, how do I drill two holes of required spacing accurately" ...the answer simple .... make a drilling jig/template on my CNC - doh...[shakes head & mutters under his breath] Hank, you're really not the fastest guy when it comes to stuff like this!)
