HI sos for got to tell you wot it is when its finished it will be a vertical steam engine
sum pics of Wat i have dun to day

 

[Deanofid]

Bob, thanks for the pics.

You don't have to start a new thread every time you put up a new picture.
Just put it in the thread you started with a couple of days ago, and stick with
that thread. To do that, just reply to your own thread.
Otherwise, your build is going to be spread out over 20 different threads.

Do you know what I mean? I don't mean to be confusing!

HI did a bit more today i had to mack up the crank shaft and the coneting rod
did not have any brass thick enough to do the job so had to silver solder two Persis together to give me the thickens that i needed.. I MUST get sum new files and just keep them for brass i spent hafe the day looking for a sharp file :

Hi kvr3000,

In your second picture down can you explain how the drive dog is attached to the lathe. It looks a neat compact solution. Not something I've tried yet but you have given me some ideas to try out for holding small parts.

Thanks
Nick

Hi Nick.

Can you tell me a little about how you machined the crank after soldering it?
How did you hold it?
How did you machine off the ends?

Thanks.

 

[krv3000]

HI Nick no problem the Bering shafts where center drilled and the shafts was put in the lathe on centers points and
a lathe dog the same type as the one i yous for the con rod to rotate it i glued a piece of brass in-betwen the web to stop it from flexing then for machining the web i set it up in a 4 jaw chuck with the tale stock of center

 

[ozzie46]

Nick, Your doing well. Your tapping stand looks like it's doing it's job too.

Ron

 

[krv3000]

HI Ron Nick is the one asking questions my name is bob I'm the one making the engine ;D right Nick their is a nother way of machining up the crank that is two mack up two supporting brackets to of set the crank basically mark out the distances betwen the centers of the bearing shaft and the big end drill and ream
two end's to fit the bearing shaft the nother ones drilled for fixing in the lathe
put a Peace of stock in the 3 jaw then face it off center drill it then drill and tap it to hold the bracket if you remove the stock before you have finished you will have to remake it as it will no longer be on center and as for the length of the bearing shafts i just cut them dawn with a hack saw and file the ends a scetch
of the set up

[krv3000]

HI sos for got to say mack the end that is gowning to hold the bearing shafts long enough to be drilled and taped once you have reamed them drill and tap then split with a hack Saw to clamp the shaft
