Thanks guys

Rob

locality, good point - I am in Sunderland England so probably best if I could get help from someone in the UK, 

I am not too worried about the time scale It would probably take a few goes to get it right, iron out any problems etc. might turn into a bit of a development project.

Thats just the kind of thing I wouldn't know about - why I need help!

Pretty much but for an automatic pencil - more modify than re invent so it works properly in my application. (I wouldn't presume to try and re invent a Rotring) 

Ian (Abbott)

I'v tried quite a few pens and pencils, the problem is they don't fit well and end up as a bodge. I think if it can be done properly I will get something that works well is convenient to use and would be repeatable.

Hi Lionel

As you rightly surmise the innards of the nozzle are pretty much standard technical pencil (although German-rather than Japanese)  except a bit longer than usual - it's the dims of the outside that need to be different.

Hi Ian (Circlip)

You are giving me far too much credit with the "fantastish feedback system??" I have just heard of one that might work!

The main problem is getting the head/nozzle/nib thing in my sketch to fit. if that doesn't work then I consign the whole thing to the "well that didn't work bin"

The other thing to mention is...

In this day and age, (when ink jets are cheap and available). Who in their right mind would want a pencil to work in a plotter. Probably just me. There's just something about a pencil line. I even do drawings for the ink jet and try to make them look like pencil.

just recently joined so uncertian as to correct forum, i am building model aroplanre engine 1st one steel quoted for crankshaft is en30b uanble to source ssmall quantity can any one suggext alternative

EN24 will probably do. M-machine sell small amounts

Whats the engine you are making as someone who may have made it could give a better answer.

Also best in future to create a new topic rather than tag it onto an unrelated post.
