Model Forum / General / Models / November 2008Stepperhead
Hi Guys I thought I would show off my efforts for your comments (cringe). Over the past few years I have been designing and building a variation on the Metalmaster. It is made from solid cast iron blocks and standard mild steel sections to avoid making castings. The essential difference to the Metalmaster is that the bed remains stationary and supported at each end and the head and tailstock can be raised or lowered relative to the bed. A secondary vertical column is incorporated in the integral tailstock to avoid an unsupported overarm and tailstock. The machine uses stepper motors to drive each axis. A separate stepper motor is dedicated to driving the headstock (Stepperhead) The axes can be operated either manually, power driven by the stepper motors or CNC operated via the lap top computer. I entered this machine in the Model Engineers Exhibition in 2008 at Ascot UK where it was awarded a Gold Medal and The Bowyer-Lowe Trophy. I have written an article which will be printed in the Model Engineers Workshop soon.I have also added some dodgy videos on utube and some pics on Flickr http://www.flickr.com/photos/32647007@N02/?saved=1 http://www.youtube.com/watch?v=Yiug1F8XCME&feature=user http://www.youtube.com/watch?v=yMxv1jU-R_A&feature=user http://www.youtube.com/watch?v=FDNTeuojC78 http://www.youtube.com/watch?v=wNxgWhizX54 http://www.youtube.com/watch?v=DMmDCHkff0c&feature=user http://uk.youtube.com/watch?v=sCsZN8Spbq8 Regards Alan > Hi Guys > I thought I would show off my efforts for your comments (cringe).

Russell Alan, I saw this at Ascot - very impressive indeed - prizes well deserved. I particularly liked all the accessories (milling spindle, etc...) - you had more than you show on Flickr on the bench under the machine (at the show, at least), as I recall.. Does the Spindle always turn the 'wrong' way, or is that only an option that you describe on the photo captions ? The topslide construction suggests more conventional rotation....

The machine normally rotates in the conventional anti- clockwise direction, I was just trying to show that it can equally run the opposite way and gain some advantages.

How do you find it in practice from the point of view of stiffness/accuracy?

It can turn quite parallel and gives a good finish and I am no CNC expert but it works well. The feed screws are only acme and the design maybe considered quirky, to be honest I am still in test mode. Regards Alan > Hi Guys > I thought I would show off my efforts for your comments (cringe).

For you it is a rendered drawing and the long text is to expose those with a limited attention span - like you Regards Alan > Too long, no one reads this. > Possibly a haux? it looks much like a rendered dwg...! For you it is a rendered drawing and the long text is to expose those with a limited attention span - like you Regards Alan Sorry Alan, I am a jerk. You really did built it..! Just could not believe it when seeing the pictures. Now having seen and read it all, I feel deeply ashamed. Dirk > > Too long, no one reads this. > > Possibly a haux? it looks much like a rendered dwg...! [quoted text clipped - 9 lines] > ashamed. > Dirk Dirk, There is no need to apologize. I can see what you are saying, I added the long verbiage too try and explain/justify the unconventional design. It is up for criticism/opinion so steam in. Regards Alan >> Too long, no one reads this. >> Possibly a haux? it looks much like a rendered dwg...! [quoted text clipped - 9 lines] >ashamed. >Dirk Welcome! Come in, spit on the cat. Call the rug a bastard :-) Well said that man. regards Mark Rand > Too long, no one reads this. > Possibly a haux? it looks much like a rendered dwg...! Wow! I'm impressed as I didn't realise that rendered drawings could look so good. Henry |
