Hi Willy, I am sorry, I did not expect you to reply so soon.  It was late here and I went off to bed.

You seem to have the technique now, those last two at 200 to 300 kB size came up well.  You are allowed up to eight, but I must admit that I find that a few too many to keep in mind with the text unless they are really quite self explanatory.

I am looking forward to seeing what the second rod does on the valve gear.

Hi All ,  Quite busy with the Governments machinations at the mo in sync with my machinations in the WKSP ....!!  the glands have been tidied up and the parts prepped and soft soldered to the "casting" ...need to wait an hour for it to cool down...

Hi Chris , yes quite complex but it is manageable !!  more work using the  .035" 14 BA studding !! the nuts are quite small and i have used a 3 BA grub screw as a box spanner ...The bottom gasket is made and the holes in the cylinder are broached out to make it easier to assemble..

More work prepping for a steam chest .. I have drilled the holes for the cylinder cap... 10 holes and i have used this multiple sided jig to space them . also silver soldering the flange for the gland then filing to shape using an aluminium plate to protect the cylinder cap from file marks the. I have used a cotton yarn charged with granite from a carpenters pencil for the making. I have made up some gaskets and bolted on the steam chest covers. I have also had to seal the Meyer valve gear holes before i can do the steam test...

Okay, that's a new one for me, gotta see more of that multi sided jig and how you use it....   :thinking:

Hi Chris, More info on the jig  ,it has accurate faces of 3 4 5 6 7 8 9 10.  So you put it in the lathe chuck and using the 'footed' square bring it up flush with the facets and the lathe bed.!! I have scribed 9 equidistant lines on this piece brass. I also use the 60 tooth /120 division bull wheel on the lathe ..however you can only get 1 2 3 4 5 6  8 10 12 divisions with it !!  also i have colour coded the teeth to make it quicker to set up...the cross slotting in the ident also has a cross slot to be able to get 120 divisions.      also i have a new tool !! this is a calliper to check dimensions, it is graduated in  1/64ths " so the numbers go up to 8 and then 1  so it is not a decimal inch tool ,but a  "hexadecimal " ??  tool ?? there is no makers name on it however ? and i have not seen one before !?it also has a screw to keep the dimension if one has to measure an inside dimension.

Interesting tool Willy and thank you for showing an example on how to use it :ThumbsUp:

But in my world it can't be a hexadecimal system as this has to be based on 16 - see :
https://simple.wikipedia.org/wiki/Hexadecimal_numeral_system

Oh and nice build of yet another old English history piece.

Hi Willy, the base 8 number system is called Octal, I believe.  As Admiral says, hexadecimal is base 16, and pretty common in the world of computing.  It’s easier to convert to binary than decimal.  Definitely works for a device graduated in sixty-fourths.

But I think they sold you a pup on that new tool.  It doesn’t look to new to me!

I also found that little jig and the way you use it for dividing.  Fascinating, it would be a challenge to try and make, especially in one piece.  Thank you for posting the detail of it in use.

And great work on that beautiful engine.  So many new techniques for me to learn.  I look forward to every update.

Hi Derek and MJM , It is strange that Hexadecimal sounds like it should be something to do with 6  but then 16 is  six...teen... also octal is sort of half of 16 ....!!!?  anyway i have now got lots of pre 1989 small diecast and brass 00 gauge and 009 gauge ? locomotive and traction engine components and kits. these are really tiny models and the parts are beautifully made with tiny electric motors...I don't quite know any thing about this branch of model making  but it seems all the hundreds of parts may be quite valuable in the right place ...so a few pics.  the phone numbers are the old 4 digit ones that are pre 1989...Here are some pics...The backwoods  kits have all the parts and the instructions..!!!
