Thanks for the idea Bob, I did this ONCE and cleaned up half my bench, by stuff vibrating off, before I could switch the lathe off.

We use a similar setup to that at work some times. We would normally use acetal or nylon bushes in the support, but your setup with the bearing is probably better.

150 years of Qld rail - no machining content
Queensland's first railway line ran from Ipswich which is about 40km west of Brisbane, to Grandchester another 40km west. That was opened in 1865 and 150th anniversary celebrations were held at Grandchester today.
It was a good day out, but to me the really cool thing was that the loco that made the original run still exists and made that same run 150 years later.

Dont panic if the drawbar dissappears
Hey,
Newbie mistake 101 ?
Have been learning how to use my Rong Fu 30 circular column mill.
Opened up the top today and ...... Oh no ... shock horror ..... I've broken it !! Damn ! - the top of the drawbar has been sucked down deep inside the guts of the machine ............. how will this mill newbie ever fix it ? ...............
Sudden idea ................ wind the quill back up to zero - Bingo ..... top of the drawbar reappears .... panic over.
So anyway - what a stunning and amazing bit of gear - eats metal - far more effective than my little Hercus lathe - quite astonishing - I cannot imagine what it would be like to have one of those huge mills with the moving knee - they must be amazing.
Am working my way through Harold Hall book - done T nuts and simple clamps - tomorrow is DIY paralells then some toolmakers clamps, and a sharpening table for grinder, and one of these and two of those and and another thingie etc. etc. etc.
I can see that I may become a tad frustrated now and then with belt changes for speeds and losing the alignment when I change heights - there are workarounds and its gotta be character building and will make help me put together the specs for the next milling machine - had to start somewhere.
Seems to be quite a lot of people out there who have done lotsa work on improvements and then continuing to use their old circular column mills.
Think I'm kind of happy that I bought this one instead of a brand new X1 for the same dollars.
Oh yeah ... Have been using the brick we made in the scraping classes at the start of the year as a big solid square for aligning work on the mill - is that what I'm supposed to do with it ? - its so heavy that it sits there stable and I dont need to grow a 3rd hand to hold a flimsy square whilst I'm trying to set up work on the angle plate - works very well.

What I learnt today, don't buy an X2 mill
Bill, you'd be more than glad you bought the one you've got rather than the X1, if mine's anything to go by. It spends more time in pieces or waiting for parts, than working.
Up to now, there has been several drive gears in the gearbox including a set of metal ones it chewed up, 2 X circuit boards, these are now in Qld awaiting repair, motor drive gear X 4, the intermediate gear X 3. The only ones making money out of my mill, is Australia Post and the spare parts places , I think I've spent around $300 on postage for parts and posting off, plus close to $1000 for parts.

Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

I learnt that a chuck slowing down while turning when tool applied to the surface may NOT be slipping belt, motor dying it may just be that the grub screw on the pullley has come loose.

CNC Lathe Crash.
Don't let inexperienced people push the cycle start button before the program has been proven!!
This crash happened at work a few weeks ago and although I knew that the turret was misaligned, I did not expect to see a broken crosslide casting. The crack/break could not be seen until I removed tooling and turret in preparation the relatively simple process of replacing the bent dowel pins.
I now have a much larger job ahead of removing the crosslide to survey any other damage and then trying to locate a replacement slide. This is a generic FEL 1640ENC CNC Lathe of Asian origin.
