1025 forum posts 204 photos | I used the MTech-3 DRO that came with the mill but never installed. I was going to put the Z scale on the quill, but may instead get a longer one for the column instead. The mag tape one seems fine for now for most things that I will be making. It is from here http://www.thedrostore.com/ it is the Promo - 3i set.
The only thing I wish about it is ,if the angle reading was in decimal degrees and stead of minutes and seconds. I do like the secondary screen and the calc functions etc. It is great using it to make the rest of the parts etc. Well worth the time to install as well. Neil |

2276 forum posts 801 photos | My installation of scales on a RF-45 clone. Y-axis scale mounted at the rear of the table leaving the front clear to use the existing travel stops. Z-axis scale is fitted to a specially built support at the side of the head. The scale is attached to a guided shaft which is connected to the rear of the clamp fixture at the base of the quill. A 4th scale is to be fitted to the column to measure the movement of the mill head. I have a 3-axis Easson DRO and intend to swop between the quill read-out and the column read-out with a computer monitor switch. (have not tried this as yet). LED lights work well to illuminate the work area. Paul.

![]() 144 forum posts 39 photos | @Paul Lousick - I couldn't figure out where to put the Z scale on mine. I have a big motor terminal block with two capacitors in the way where you have put yours. The mill is in bits now with the terminal block off so I'll have a look and see if I can relocate it. Where are the terminals and capacitors on your mill? |

1394 forum posts 103 photos | Y-axis scale mounted at the rear of the table leaving the front clear In normal industrial parlance, that is the X axis (table left-right movement) - the Y axis is the table front-back movement. Nice installation, with the table scale in the "optimum" position nearest the fixed dovetail (opposite side to the gib strip) . I am currently looking at a 3 axis DRO for my FB2 clone & it oden't look like I have enough room to put the scale at the back of the table without restricting an already short (140mm) Y axis travel.

2276 forum posts 801 photos | Nigel, Typo mistake ('Old timers' disease problem ). Hi David, I must haver a different motor on my mill. No external capacitors. Paul. Edited By Paul Lousick on 01/05/2018 10:52:14 |

1025 forum posts 204 photos | I found in the shed today a 3phase 220V 1.5 kw motor. So latter I will change the single out for the 3ph and run a VFD to get other speed ranges and to get more RPM on the top end. The other option is to get the 2KW 2900 rpm 220 V 3ph motor and then run it at 100% to a reduced rpm limit, instead of 100% and then going to 85hz on the 1450 rpm motor. On my machine the LH side where I fitted the Y axis DRO is the non gib side. On the front however, it is on the gib side. I don't yet have a good picture showing the access to the stops or the gib locks. On the same side as the handle to lift the column, I have coming a digital scale like what I have put on the quill. So when lifting etc, I will have a reference. I am not sure apart from convenience the advantages of the DRO of the quill on the box. Out of curiosity, what have people done to get the column square to the run of the table in the for and aft plane? Mine is out by about 0.03 mm to 0.04 mm over the 129 mm quill range. What oil do people find is best for the gear box head on these Mill? What will help to keep it quiet? Thanks, Neil |

Hi David, I must haver a different motor on my mill. No external capacitors. You have exactly the same terminal box as me but yours is attached to the motor. I don't think mine was, because I could not get the Z scale to fit on either side of the gearbox. Thanks for the photo, when I get mine back together I'll see if I can do it like you did. Regards, David. |

1001 forum posts 49 photos | You will have problems if run the Luxs faster than they come 1250rpm. Quite easy to get a C type glass scale on either side of the head, done it 13 yrs ago positioned near where Pauls is, credit where its due. Also needs the pin sizing in to reduce quill rotation. Hydraulic 68 plenty good enough from Smith and Allen about £17 delivered for 5 ltrs, changed mine for sealed SKF bearings 8 yrs ago, the oil dont froth like the stuff that comes with it and if its good enough for Harrison head stocks its more than good enough for chinese. Neil i wouldnt be putting X axis there you cant use any stops, poweer feed (trips 2 and stops) and cant use a rotary table with dividing plates or even use the must have bed locks without socket, extention and bar on tap. Power feed packed up on mine yesterday mid job didnt want to spend any more on it, as good as scrap 8 yrs ago. Turned 3pm ordered from Goodwin saves me a trip to Brum or Tamworth, delivered by 10.15am next day. Shame could have been £360 put towards something decent now may be able to use it as a knee lift or Y axis motor.

1025 forum posts 204 photos | If I change to socket head screws, I can use a long series T bar hex key, but as is, can just use a ring spanner. I can also add micro switches from the left or right as well if I go the power feed option. From the front the lock screws are below the scale . My rotary table will be on a raised mounting block, so that It can be used anywhere on the table, and not have to have it hanging off to one side. Still got the covers to go.
Only the centre lock can not be accessed from the front, and has to be accessed from the top.

1001 forum posts 49 photos | Missing the point Neil, the dividing plates have to drop down the side of the bed. On mine to clear or be level with table you would have to raise the RT up 2.4" thats over 60mm. You would now run in to the realms of head height max adjustment with literally a chuck on RT, drill chuck and a tank cutter 1 1/4" dia which isnt very long shorter than an 8mm drill flute. The inside of dividing plates to table is 33.6mm at present pulled out in the T slot. Limited as to where the RT can be positioned on the three T slots, mines using the middle one. Do like allen bolts bit they fill up of swarf and debris. Lastly think your beds shorter than mine and Pauls, i originally had actual 24 1/4" travel. After power feed its down to 21" region. |

1025 forum posts 204 photos | Thanks for the explanation Jon. Yes mine is the shorter table, and I have chosen to limit the X travel so the Bed does not go pass the cross slide block edges. But with the full travel, it was 610mm, but the end of the table over travels on the cross slide block. Yes it is about a 60mm spacer that is required. My chuck selection, is a low level self centring 4 jaw, and a regular 4 jaw as well. The 3jaw chucks I have are the standard taller rmodels, and as you point out, can run out of room real fast, I also have a ER40 low level collet chuck . It is still a work in progress, so some other changes may happen yet. Neil |
