Welcome to the new digitalhobbyist forum
I really appreciate the interest shown in the last 6 hours of starting this new forum.
Currently standing at 14 members, and most names I recognise from other forums. My intention is for us all to benefit from new affordable electronic assists in chipmaking, be it metal, wood or any composites, share ideas in our? quests to produce projects and tooling in our hobby shops. This forum does not negate or ignore the need to apply manual machine practises in tandem and welcome any new?innovation ideas, but there are plenty of other forums available for general hobbyist?s interested in machining. I specifically have set no No ground rules yet except the normal zero tolerance on subject matters of Race, Religion, Politics, Profanity and to treat others as you would expect to be treated. Disagreements naturally will occur between forum members, tempers may fly, but lets get?going first and sort out things as we move along. Neither am I an autocratic or dictatorial person, and purposefully I have not signed off as Owner or Moderator of this new exiting forum, you all know who I am when joining. Moderation if necessary will be minimal, as we should all be capable of this task amongst ourselves. The saying is true,? "you don?t know what you dont know " but lets get going and see how it all pans out. Newbies to our specialist niche hobbies are very welcome to join and will give them the courtesy they deserve, we all started by learning from somebody. Posts to be on subjects referencing our hobby machines,but if you happen to own a Bridgeport Mill or 9" Southbend lathe then this is not a problem, we should not limit posts?. as enhancing our hobbyist machine tools including 3D printers?is what this digital forum is all about. Lastly, as you may be aware from other forums I have a record of posts referencing good sound work safety procedures and I will not be politically correct in my replies when reading or seeing unsafe practises.? Again, very pleased already with the interest from a great bunch of guys signed up. So lets see what happens, the future is all around us at affordable prices. Thanks very much. John? Lindo I will not let you down. John?? |
Re: ELS project

Prasad,
I am in the midst of implementing a similar ELS project to John's, with his help and suggestions.? I prefer to think of it as "super-ELS", as the original ELS concept controlled only the lead screw, as I understand it, so that the user could thread basically any pitch.? Super-ELS, as John and Richard (in the UK) have implemented it, (based on the software concept of a Russian gentleman whose name I don't know), also controls the cross-slide.? This allows complete automated threading, and also provides taper cutting, various turning options, etc.? I went with some rather over-sized motors, as you can see in the photos.? The encoder shown is driven off the spindle directly. I am really looking forward to finishing this and putting it to work! -- Regards, Charlie New Jersey, USA |

Charlie Well done A very nice forum post with clear photos. Thanks John On Fri, 9 Aug 2019 at 21:14, CLevinski <clevinski@...> wrote: Prasad, |
Re: Thanks John
Ralph Welcome aboard. If I can help you I will, and we also already have some super top notch futuristic signed up forum members. from all over the world. Amazing. There wont be anything that cannot be sorted out. Futuristic hobbying that is? LOL.

Hi Charlie I know and I am planning to visit you one of these days. I am excited to get going but as you know, too many open projects on hand. Everything is important. I will phone you soon.? Prasad

Re: ELS project

I want to do this, I wonder about the motors, yes Charlie your motors appear to be huge. How big of a motor is needed for Z and X? Anyone have some extra motors you want to get rid of? I believe the original ELS has the capability to drive X or it can be added. Ralph On Fri, Aug 9, 2019 at 3:25 PM John Lindo <bechetboat@...> wrote:

Hi, Ralph,
I was not aware of that.? I thought the cross-slide was not considered.? My apologies if I am wrong.... -- Regards, Charlie New Jersey, USA |
Re: ELS project
#RELS
Ralph,
My motors are NEMA 23, 113 mm long, with a 2-phase holding torque of 3.0 N-m.? It was certainly overkill for the cross-slide, and may be excessive for the lead screw, but I have this philosophy... I would rather have extra torque and not need it than not have enough torque and wish I had speced a bigger motor!? I bought three of these on sale, intending to use the third one for a power feed on my mill.? I have attached the spec sheet FYI. John, I know your motors are NEMA 23 but not as long.? Do you know the torque spec for Ralph?? You have never had a torque issue that I know of, and you push your lathe to the edge of its performance envelope... -- Regards, Charlie New Jersey, USA |
Re: ELS project

Charlie I cannot believe those are NEMA 23 motors I thought they had to be NEMA 34. I have a bunch of NEMA 23 motors maybe I could/should play around with them. Of course that would be this winter, right now I have too many "priority" must do projects none being in my shop. Ralph On Fri, Aug 9, 2019 at 4:21 PM CLevinski <clevinski@...> wrote: Ralph, --

Re: ELS project

But, but, but Charlie, you're modifying the lathe! Are we allowed to do that? I've always adhered to the maxim that if I own it I can modify it however I want. Hardware, software, whatever! And if I'm not allowed to modify it, it's just a rental. I don't rent much. :) Go for it!

like to submit his third photo as an interim image. ---Mark
