As im quite new to high-tech machinery, (like lathes for example) I have a few questions regarding them:
This link contains design criteria for static and dynamic o-ring applications.Alster370 wrote:1.) what depth of cut would I need for an o ring groove on a piston of 19mm?
If a work piece is long enough to require removal of the tail stock, it's much to long to run unsupported.2.) Am I ok to remove the tail stock so I can work with a longer work piece?
What's the o-ring inner and outer diameter?Alster370 wrote:1.) what depth of cut would I need for an o ring groove on a piston of 19mm?
As long as the piece is properly held, and you're working near to the chuck, it should be fine. Consider getting asteady rest though.2.) Am I ok to remove the tail stock so I can work with a longer work piece?
Stop using it immediately and have it checked out by a competent electrician. It could be down to static buildup due to friction, but I wouldn't risk it.3.) I sometimes get a fairly nasty shock when I have the lathe running and my hand is touching the variable speed control knob, despite it being made of plastic, any thoughts?

velocity's link is useful.Alster370 wrote:tube inner diameter, is 19.5mm. Im also looking for what size o ring I would need, as I am unfamiliar with them and which size I should go with for a piston of this diameter. Any general rules to follow concerning this?
Careful with long thin material, it can whip around and hurt you.Ok, I think i will try without the tailstock and make a decision based on its balance and how heavy the work piece is. Also on how much the work piece is exceeding the maximum length with the tailstock.
Is the drive belt rubbing against the body?Also as a sidenote, this electrocution is not while im cutting or grinding, just as the machine is spinning the work piece.

So i just thought id buy 22mm round bar and trim it till its a good fit.Il check in a minute, I can run the lathe with the cover off right?Is the drive belt rubbing against the body?

its quite expensive too . Il definitely get some aluminium barstock, soft, strong and surprisingly cheap 
Told you soAlster370 wrote:The belt had bits of rubber still attached to it where it had been cut, so Ive shaved those off and I don't get electrocuted any more!
"soft" and "strong" ehIsn't delrin acetal?

Sorry Alster, the world doesn't work like thatsoft, strong
Did you totally disregard the link I posted for you? All the necessary info is there.Alster370 wrote: Im also looking for what size o ring I would need, as I am unfamiliar with them and which size I should go with for a piston of this diameter. Any general rules to follow concerning this?
