hi all well as sum of you no my compact 8 was missing its compound slide and i had modified a one of a myford to fit. well having a workshop vised from mick IE micktoon he thinks that he new where their was one any way after sum emails i picked it up from john's IE doubieboost and i was over the moon as it fits my lathe so her is the refit so fare its a emco one all in all in good order just needed my loving touch striped it dawn and gave it a repaint the three jib screws Will be replaced as will the nuts and i will be making two new handles for the feed and i fitted a toothed belt on to the mane body see pic i then did the graduations on the top slide and on the bottom ring for angels this my tip on the job in hand don't clean off the rings leve the muck on concentrate on removing the muck from the numbers and the markings i do this with a needle in a pin chuck the reason for leaving the rust on the rings them selves is 1 the pant wont stick to it and 2 you is only removing a minimal a mount of metal if you clean the ring before panting when you cume to remove the pant you is also removing metal and if the markings are worn then you is making it harder to reed them the pant i used is car spray pant right sum pics

Hi,

there nice little lathes the Compact 8, there is on thing I'm not to keen on, the quick change tool post. The side that has the tightening bolt at the top, has more than half the nut outside the tool holder!. I find them fiddly to adjust the height, I haven't thought about it yet, but I feel sure there's room for improvement!

Nice job, regards, Matthew

Mine had rubber rubber washers behind the bolts, it was all soggy to adjust. I removed them, when it's slack enough to adjust, it lowers, so you have to compensate, adjust lower, then tighten, re-check, try again and if your lucky you might get it right on the third go!

It's certainly better than no quick change!

Regards, Matthew.

Hi Bob, Looking good

and will be doing your turning jobs in half the time

Cheers Mick.

No rubber was much better than gooey! I'm busy with my dividing head at the moment. Curious to see what you come up with.

Bob

Your fingers always seem to do their magic on anything that you set your mind on restoring or repairing. This is just another excellent example. Thanks again for sharing it with us all.

Best of luck with the your heart procedure. Don't be too naughty with the pretty nurses. I expect you will be back in the shop better than ever in short order.

Cheers

Don
