NickG:
Think I might do, would be good to have a dedicated tool for the job too as not everything is done in the milling machine. Steam engine is looking great by the way, some nice aesthetic detailing, I should definitely learn from some of your methods here ... great write up, keep it going.  :clap:

Darren:
Thanks Nick,

Don't worry, this thread is set to continue, I've been a little distracted by another project..... :thumbup:

Darren:
I drilled some holes in a little plate tonight.....

So what I hear you say, well it took me ages that's what.........., all night in fact.
Jeeze the concentration, nearly did me in... :lol:

I marked it off the other day, but I used the mill to position all the holes. The mill says my marking wasn't that accurate, but they did show me a couple of wrongs turns on the mill before I flunked it :thumbup:

Only one more to do  :bugeye:

I need to make two 18mm holes in this plate and I'm not sure how to go about it.
I'm guessing drill first to say 14mm, biggest drill I have under 18mm and then use the tool in the picture. I don't have a boring head for the mill, but this is like a miniature version of one.
It's for the lathe turret.

Any tips chaps?

sbwhart:
Yes

Have a practice first in a bit of scrap you don't want to drill all those holes again in a new bit of plate, perhaps you should have done the 18mm hole first then if it went wrong your not scrapping off too mush time.  :bang:

When you get the right size in the scrap mark the tool position in some way so you can get back to it when you do it for real.

That tool look like its got two way adjustment you only need one so lock one up.

Is the tool steel square or round?.

and keep your fingers crossed  :lol:

Have fun

Stew

Did I give you any small gold plated boring bars, if so they would be great to do this job just make an holder for one.
