JTisher:
 Beautiful work Arnold. I look forward to seeing more :headbang:

No one will spot the extra length of the lower left recess, Arnold....  :wave:

Also, no one sees both sides at once, to compare.  :thumbup:

Nice work, all of it!  :clap:

Really nice work on those rods arnold -  :offtopic: I've got exactly the same pencil torch as you - mine seems to do what it wants !!

Thanks Gents  :beer:

Nice catch David - the grooves in the bottom one all end up 1mm closer to the holes than the top one's.  I neglected to write down the dial readings when I did the first one, and when I flipped it, I couldn't remember and guessed  :palm:

Nick, mine also does what it wants...  It's actually volunteered to donate its jet and filler valve for making my own gas tank and regulator for firing boilers - just as soon as I can get my hands on a better pencil torch.  I have another pencil torch of a different make, but it leaks its gas out; If I fill it up and want to use it a week later, its empty.  So I don't use it any more, as its a potential hazard.

Not much done on the loco today...

Some 5mm hex brass, turned down to 3mm and threaded M3 for a bit:


After parting off and repeating, I had the outboard rod bolts - with a dud that I parted off slightly too short (the head is too thin) as I was doing things by eyeball rather than properly measuring:


Having made those, I was hit by "designer's block" - and I wasn't in particular interested in small work today, so I made up some clamps for my tooling plate - I'll post that in the tooling plate thread.

Regards, Arnold
