Tube notch central

Despite being preoccupied with milling machines and related paraphernalia - and even decorating! YES I've made a start on painting and tidying up the walls in the cellar. The floor is next for consideration, it needs all the oil getting out of the concrete first but after visiting Bob Brooks workshop a while ago i was amazed how much light is reflected back up off his painted floor, and with no windows the lighting in the cellar has always been an issue.

I've managed to get a few more tubes notched up and tacked into position in the frame. It's really starting to take shape now and most of the tricky tubes are already done. Only a few more tubes left and i'll be moving on to all the brackets and other bits that will undoubtedly take up a lot of time.
I have a whole front end (forks, brakes, wheel etc) to go with the frame, but the forks will need shortening and stronger springs fitting, and i can't do those things until i have a back wheel and tyre in place so the ride height & ground clearance can be set correctly.
It looks like i'll be building the back wheel from scratch, probably following the design from the bopchop wheel but fitting wider rims.I don't like the look of the side drive wheels that are popular at the minute, and i can't find split rims with beadlocks, so they might have to be beadlockless.

With new mill now in situ i spent 2 evenings  this week fitting a Digital readout and Linear scales to it. I bought them as a kit off eBay, and initial impressions are that it's very cool! No doubt they will quickly become invaluable, as it opens up a whole new world off accuracy and repeatability. Not like it wasn't possible before but all that measuring makes it very tedious. This looks a lot easier to me!
The mill itself seems pretty impressive so far too, it produces some very clean cuts, doesn't vibrate when making decent size cuts, and the variable speed is a revelation!
