One of the main problems with home made z axis is movement due to vibration and keeping things locked so it doesn’t vibrate deeper during a cut that was a problem with the ones I made but this counter balance idea just might go a long way to stopping this.
To template mill you want easy movement but then for all the rest of the milling you don’t want any movement at all. Your mod might just do this what type of locking do you have on your z axis and are you using legacy’s split nut for engaging and disengaging its leadscrew. I’m really interested if this mod will copy details like sharp edges you may have to have a handle to manually Raise and lower over sharper profiles also while manually moving the x axis. please post pictures of it working when it’s finished Bill From: legacy-ornamental-mills@googlegroups.com [mailto:legacy-ornamental-mills@googlegroups.com] Sent: Friday, 20 March 2015 10:18 AM To: legacy-ornamental-mills@googlegroups.com Subject: Re: "Z" axis template follower today's progress...and hey curtis, bearing set up, as you inquired about...set up the 1/8" metal as i described previously...all went as planned...two pieces of 1 1/2" that slid into the legacy rail and some 1" to "box" it out, so to speak...welded the split collars to this assembly...held in place with one 1/4-20 set screw...easily removable...the split collar holds the bearing, which has a flange on it...slid the 5/8" shaft in with the chain sprockets...some 5/8" shaft collars on the end and all is in place and working as it should...moved the acme thread assembly to the front side of the router carriage(originally was on the back side) as the acme rod was right where the shaft for the chain sprockets wanted to be...this was not such a bad thing as the linear bearing rails and carriages had pushed the carriage outward...just a couple of black spacer blocks did the job...just need to now set up the chains and this mod will be done...some minor additions will follow later, like an arm to control the router carriage's up and down movement when following a pattern...an arm to extend outward on the backside of the "Z" axis that will have the capability of holding various diameters of small bearings that will ride on any pattern/template... and some type of brackets that will hold the template onto the mill itself...these brackets will have adjusters built into them to set up a template precisely...hope to make a video of all this soon...waiting for spielberg to return my call...as always, all comments welcome...joe -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
