$60.00 is my lowest price. I will be around all day if you're interested in picking them up.
Thanks for the great deal. Nice shop BTB. I'll want to visit again when you have that CNC up and running.

Hope you put those scales to good use. You are more than welcome to come by any time. The CNC mill should be up and running next week if Canada Post delivery forecast is accurate.

My install of the competition pair available here
Well..... after much dithering over how to proceed, I finally got my scales installed.
For the X-AXIS I mounted a piece of hardwood on top of the taper attachment bracket, attached the scale to the hardwood strip and secured the data reader to the saddle utilizing one of the unused follower rest mounting points. Voila.... didn't have to drill and tap any holes
The Y-AXIS proved to be a real challenge. I couldn't use @Bofobo's approach due to my taper attachment getting in the way. If I mounted the scale across the top of the saddle the data reader bumped into things (chuck, tailstock etc). Finally, I came up with this. It looks clumsy, but it seems to work ok and is out of the way and I only had to drill and tap one small hole in the taper attachment extension.
It all seems to work pretty well. On the X-AXIS the DRO reads spot one against my dial indicator. On the Y-AXIS the DRO reads spot on against the cross slide dial and my dial indicator.
I'm pretty pleased over all.

On mine there is simply not space to fit it - on the chuck side I have attachment for follow rest and on the other side I have adjustment screws...
One thing I worry about it hanging like that is support - I guess for 7" its not a big deal but for longer length the scale would have tiny bow in it due to its own weight.

For this install I took possession of the FR attachment points. If I somehow snag or make a FR I'll have to reposition.
It bow's alright. I'm thinking of doubling up or tripling up on that support bracket. That scale is a good 6" longer than it needs to be so that doesn't help. I could cut it down if I wanted. An annoying thing about these scales is that the data reader takes up a good 3", so to get 6" of travel you need to mount 9" of scale.
The slickest (neatest) DRO install I have seen on a lathe to date is what @eotrfish has on his EMCO.

Only need about half the reader on the bar ..... the trick is keeping the reader and bar engaged, that's how I managed mine to fit within the chip guard. Tweeting time was under an hour for that knowledge acquisition
I agree. Part of why that was possible is Newal Microsyn have small diameter encoders 6.5mm dia tube, relatively compact & re-orientable reader heads & smart mounting/adjustment hardware. They are spendy though. The Chinese glass scale systems are just getting better & better, price & quality wise. I wouldn't think twice about the systems out there now, they are a fraction of the cost of what DRO's were even 5 years ago. The only downside is they still seem to be a bit bulkier. Not as much an issue on a bigger lathe but more challenging on small machine available real estate. But where there is a will there's a way as you have shown.
Soooo.... that aluminium flat bar support wasn't working for me. When you moved the cross slide from stop to stop you could see the end of scale rise and fall a good 5mm.
So, I replaced it with a piece of hardwood that leveraged against the fact I could use the taper attachment slide bar as an additional support point. Not seeing any deflection on the end of the scale now.
Had to mill that HW bar to make her fit which was a interesting experience.
