My home built mini milling machine (using some Unimat SL1000 lathe parts) video 1 HD
Here is the link to my latest video for this great little milling machine: https://www.youtube.com/watch?v=Cf9I5XkKmfw This video was recorded on 24th May and shows my home built mini milling machine which I created to help me with the locks I make and refurbish. The mill uses a few parts from the Emco Unimat SL1000 lathe like the head stock quill, head stock spindle, head stock feed lever, Emco drill chuck (M12 x 1 thread), motor (later type UG77 motor) and motor bracket. The rest of this great machine has been made up and put together by myself using a small cheap X Y milling table bought on ebay for £30 as the main structure for the X and Y movement. I made the milling head spindle holder and column myself and also engineered it (based on the Emco Unimat SL1000 milling column so that the milling head can tilt left or right and it is locked in position with a large M12 allen grub screw (same setup as the Unimat SL1000 milling attachment/column only a bit more robust!) I was working on building a better motor (Induction motor instead of a universal brushed motor) for this small milling machine and I have already cast from Aluminium a totally different motor bracket (which is not shown here), as I plan to upgrade this mill later on this year to the new better drive motor. The Unimat motor is just a quick fix temporary solution because I had a lock refurbishment job on and I need a small milling machine to help me make some brass face plates and keeper plates for this mortice lock, Normally I would either have to drill a couple of holes through the brass plate and then open up the holes with needle and warding files until the face plate (or keeper plate) is made, This is very time consuming! and my only other options to speed this up is to use my larger Emco FB-2 milling machine or to use the filing machine I made back in the summer of 2015 (this filing machine works well but it is rather slow because I made the mistake of using a 1400 rpm induction motor when i should have used a 2800 rpm induction motor which would have worked much better) So this is the reason why this light duty mini mill was made to help me out with the locks - I will post another video in due course when the drive motor on this mill has been swapped for a better motor :) I also plan on improving the column for this mill by milling a 8mm keyway all the way down the column post, fitting an 8mm x 8mm mild steel bar to the column post (which will be the same length as the column post), broaching an 8mm keyway in the milling head support bracket and adding a height adjustment handle/leadscrew so that the milling head/milling head support bracket can be moved up and down quickly and more precisely rather than the rather basic Emco Unimat SL milling column set up that it has now at the time when this video was recorded. I am also working on yet another mini miller which is somewhat based on the Emco Unimat 3 stand alone milling machine (or Emco compact 5 stand alone mi
