Hi John,

Many thanks for the kind words.

All the Drummond flatbeds are 3.5 ins so mine is the same size as yours...ooer missus! :)

It is half the fun figuring out how to make stuff fit; I look at pictures of milling machine set ups and think that it makes life so easy...but would I appreciate the hobby as much? It would seem a bit like work. Of course, the other thing is cost, not just the machine itself but all the tooling required.

I have got myself set up really nicely to be able to tackle almost any job within my scope. I had to bore a 5in diameter, 1 foot long gearbox sleeve for work and the little M walked it...after I had made an indexible boring bar from a length of key steel and an odd insert...then mounted it the right way up! :lol: :lol: :lol:

I have to say that the B/M type bed is as stiff as anything and the M headstock bearings are fabulous! I can cut 1/4 inch of cast iron in back gear! The B headstocks struggle to not chatter at that.

There is something about the Drummonds which gets me every time. The Super 7 is quite fiddly to use as I am used to, it wants to automate every movement and I don't trust it not to go too far. The lack of leadscrew clutch means that you have to turn all the changewheels as well to use the leadscrew handwheel which is hard work when I have got the fine feed all set up nicely. :doh:

Horses for courses, use the machine for the job...but hooray for Drummonds!!!! :D :D :D

Work has been postponed!

There is something wrong with my shoulders and right arm. My right thumb is numb and won't bend at the top joint. :( :( It is like I have permanent cramp in both forearms that then seize up.

Thought it was a trapped nerve. Went to an Osteopath but after cracking me up (literally) she says I have to go back to the quack. :scratch: :scratch: :scratch:

Could be something to do with the medication I am on for high blood pressure.

Tried to get on with the piston centre but a muscle spasm on a vital cut buggered it a bit so I daren't risk doing worse! :bang: :bang: :bang: :bang: :bang: :bang:

A very unhappy bunny! :( :( :( :(
