George Greer,
"digital scales and remote readouts, for the X & Y axis....where would be a good place to find one for my mill, and brand name?"
Donīt really know about a good place, but a cheap (almost as good, IMHO...   :lol:) would be Arc Euro Trade
http://www.arceurotrade.co.uk/Catalogue/Measurement/Digital-Readouts. No brand name (Chinese, of course). I have those, and so far (6 months, +/-) canīt complain, theyīve worked as expected. There are lots of alternatives, glass scales, far fancier readouts, FAR higher prices, etc.
Iīm in fact planning to get a Shumatech readout, as soon as they are available (maybe August), and then Iīll move these readouts to my lathe.
I donīt think you will easily find cheaper DROs, except maybe in ebay.de. Same scales appear there now and then.

P.S. Seems that Mr. Swali is out of remote readouts (Digital Display Unit) atm.   :doh:
P.P.S. Thatīs one tidy shop!

Congrats! I got my BF20vL this spring... Its a GREAT mill. I had some issues with mine but I got it all sorted out now... Some things to look into on your mill that can save you some grief.

First thing I had a problem with that took me the longest to sort out was the tram of my head. I could get it set left to right, but it seemed to be tilting forward 0.1mm. At first I found the cover for the gears (between the Z axis slide and the head) had some screws keeping the head from being 100? true to the Z axis. later I found the TRUE problem. My mill only had 1 bolt locking the head swivel in place. This bolt essentially was pulling the heat out of true and causing my error and throwing my tram out....

Here is a link to the topic I had running over at another forum (http://www.cnczone.com/forums/benchtop_machines/109730-bf20_shim_column_solved.html)

Another item you may want to look into is to make up some adjustment screws to help you tram the head. Machinechick came up with these tram aids... work great...




I just installed a ShumaTech DRO and its WELL worth the money.. I cant believe how much it has helped me be dead nuts accurate and it has doubled my rate of production.

Another Mod that I came up with was to make a Power Draw bar... this is another massive speed savings. Here is a link to my vid on Youtube

So this is just a taste of what is out there for the BF20 Mill. if you are searching around you will find that allot of manufactures are making these mills with a wide range of quality. Check for the Grizzly W0704 or the Weiss PM20 or PM25.... allot of these mills seem to be getting converted to CNC... Looks like you and I got a winner when it comes to the possibilities.... now if I can find or purchase some skill I will be set :)

Hi this looks so simple am I righ in thinking that it is just a drill used on hammer to remove the draw bar ?? My brain is even worse than normal due to things my doctor has forced down me so am not machining or thinking stright so sorry if it is a stuppid question.

Bogstandard:
Peter,

A power drawbar would be just perfect for yourself, and they can be made up fairly cheaply. It all depends whether you want remote operating buttons, or whether you can cope with just the butterfly handle on the power driver. I bought a 3/8" drive version for helping me with hand tapping, and it was less than 20 squid.

I can't get the above link to work properly, so I can't see what ZD has set up, but seeing as you can't machine at this time, if you need brackets and stuff making, don't be afraid to ask.

This is the sort of thing I was on about.
