Looking to get some spindle liners for my machine and I’m curious as to how far out the back of the spindle they can be extended. I got a quote from trusty cook and they said 4” max. But those are plastic.
My machine has a 52mm spindle bore and the drawtube is only 30.75” long. There is about an extra 4” by the time it gets to the front of the jaws or collet Chuck though. Basically I can fit a 36” bar no problem as it sits.
I would really like to run 4 foot bars though.
Can the spindle line be extended say 10”?
That way with my part extending into the machine a few inches practically nothing sticks out the back of the liner. I would like 11” extension as then I could just make a 1.75” liner and use a set of haas liners I was planning on purchasing as they are 42” long
Whether I extend them or not I got .109” wall tube .030” over size for all my common bar stock. Got 10 sizes and it ran me about $300. For 48” lengths. I figure I can make the biggest first and work my way down one at a time.
So what are the thoughts?
Is .109 thick stock heavy enough wall?
Is 11” too much extension?
Will making my own be a terrible idea?
Should press the collars on or weld( figured welding would distort the tubing. May just use bearing retainer.)
Figure it will take me a day tô do and a full set would be over $3000 so I’m still making sop rate.
