Re: What is the 'BEST' Unimat ?
As you have already surmised there is no answer for that question. It depends on what you want to do with the machine.
Additionally I think you will find better availability of parts and pieces to put an SL together to do anything that you want to do, and for less money. ? |
What is the 'BEST' Unimat ?
Hey guys, I'm still on the fence, as it were, as I've not found a deal i can afford for the most part ! However I would like to pose the question 'What is the 'BEST' Unimat ?' OK i realize that all depends on what you want to do ! Condition and Cost are also a consideration off course. As is what all is included in the sale Attachments etc. Whats the capabilities of the machine etc etc. With my limited understanding of the range of attachments, the capabilities of the different models versus other models in the range I am leaning towards the Unimat 3 for the sole reason it has an attachment at the rear of the bed for a Post for a Milling Head. I think this is a reat feature but believe that other models can also do this but i dont know how, as they lack this feature. Your thoughts and suggestions are ofc appreciated. Anyone wanna sell me a Unimat 3 cheep ? :D

Re: Drill chuck
¿ªÔÆÌåÓýHi Gang: It is easy to drill and tap a drill chuck for M12x1. I've done, 1/4", 3/8" and 1/2" chucks. Carl. |
Re: Drill chuck
Not that I was asked, but I have the actual Emco drill chuck that came with my DB, which is very good. However, I consider my Jacobs (USA) 7B on a 3/8-24 x MT1 arbor a very nice upgrade. However, it is a 0-.25" range, and sometimes I need more capacity. I have a larger Jacobs, but it is very long, so sometimes I will use my 2" Unimat 3-jaw chuck. (I normally have my 4-jaw on the headstock spindle.) |
Re: Drill chuck
Ah! the plot thickens! Well if it fits then give it a go if you think it would be useful to you - assuming you have a DTI just check it for concentricity first! I'm still confident it comes from a hand drill and as these were never meant to be that accurate you may find that it is also not that accurate! Good luck

Re: Drill chuck
¿ªÔÆÌåÓýHello Pete and Dave: It is a simple chuck that are often used on old "egg beater" hand drills. The missing part is the 1/2"-20 threaded spindle that pushes against the disc and thus the jaws. It would be tough to make this chuck run true since the body isn't locked to the spindle, but wobbles with the screw thread. It might be nice for a hand chuck by adding a handle with the required thread. Carl. On 9/9/2023 10:59 AM, pete wrote:
Hi Dave, no this is not a Unimat chuck, the unimat chucks are tightened with a key much like an electric drill chuck. This chuck is a keyless one from a hand drill of some sort! |

going to require a great deal of work to get it up to

bidding doesn't get too crazy tomorrow.

Re: end mill holder
Thanks Dick, yes, I understand that now, thanks for the clarification.
Mike also confirmed (he mentions it in his post above but I didn¡¯t pick up on it) that he used ?a dial indicator gauging his existing E16 holder (which is also 8 degrees) to set the taper slide. Brilliant! I¡¯ll be using that method, I think. |

Re: end mill holder
Peter,
I use a dial travel indicator on both axis to set the taper. I hope this describes the setup enough to be clear.
