Hi folks,...i have put the Coombes to bed for a while and have cleared the decks to do some work on building the corliss......milled one of the bed plates to size after marking out the points to mill to...a lot of working out the dimenions ...definetly not a stuart and turner jobby...went to one of our local Dentists and Scrounged about a dozen tiny little Tungsten ( i think ) ball ended rotary burrs ...they are perfect for spotting or starting holes in awkard positions I used the Cowells mill with a cutter normally used for cutting Carbon fibre ...like a knife through butter the set  up for the slide bed will be some what tricky  I think,
                                      Cheers ,
                                                John.

John are you going to start a seperate thread about your Corliss engine?

You might even convince me to get on with building my  :o huge one .

I will more than likely do just that...invested in a descent calculator and a couple of (crap,o cad)  Pukka pads one pocket sized...I have a brand new Bosch industrial l electronic \router, which i am going to make a rig to allow for more  milling ops ...will see how that works...currentlu browsing fora build sequence ...if I can find one.

                                                                                                       cheers,
                                                                                                                    John.

Hi folks...back in shop again..Corliss cylinder on hold while i make a parellell long grinding tool from a tapered stone !!!I am going to try grinding out the hard spot'''anaway ,
now back on the ''James Coombes''...had to make a new ocillator sheave out of bronze...and make good fit to the big end.  some minor faffing about and then I gave itfull power from my new compressor...AMAZING!!!the reluctant sod actually works ...I ran it while yelling at top pitch for a photo or videoAll cloth eared ?***!!It eventually slowed down and stopped ...I found that the slotted  grub screw was notholding the sheave  so need to obtain someallen type grubs...
 The bit that I am happiest with is that my design changes work...
                                                 All the best for now...

Hi John,

A runner  8)

You need to host the video on something like Utube and then provide a link to the address (URL) in a post here if you look above the smilies there is a button which adds the characters to the address to make it work on the forum.

 :whoohoo:  A runner  ;D

I see you find focusing the camera as challenging as I do  ::) Is there an automatic focus setting I find using that helps no end.
