That started life as a bit of 1″ square bras, hacksawed to about 5/8x1x2 and then flycut to size, next the bolt holes and cavity were do in the mill but like I said the lathe will do the same job.

 

 

 

Most of the ME metal suppliers will have the metal mine probably came from College Engineering.

 

J&L do the long ctr drills that one is 1/8×3″ , I also have a 3/16×4″ but you can get them upto 6″ long. If you go to their site, click the virtual catalogue and look at page 99.

 

As you say a picture make it easier to follow thats why I took those shots yesterday while I happened to be doing a steam chest.

 

One thing you would have to do if using the 1/8″ ctr drill that I mentioned above is to fit a “neck bush” this is just a bronze or gun metal bush that fits into the chest and gives the valve rod a more suitable metal to run against, on full size it had the advantage of being easily changes if any wear took place. You can just see the brones in the second pic at the bottom of the stuffing box and where it enters the valve chest in the first.

But is it a traction engine steam cylinder or a diving helmet?

 

Seriously, that’s lovely work Jason, is it the ME Allchin?
