It certainly sounds better to me and it seems to run smoother.  The 'chuffs' are more even now. 

Great job!

That's a beautiful engine, Stuart!

Lovely runner.  And I like the blue color.  Very nice.

Thanks all, very much appreciate your kind comments.

Well, next up is a sort of refrubishment of my lathe. I want to beef up the cabinets it is sitting on, replace the spindle and other bearings with higher quality American made bearings, re route the coolant hose and add a DRO. DRO arrives today! So that will be a fairly major project - I have two pieces of 1" thick steel plate to put on top of the cabinets and give it a firmer surface to sit on - hopefully take the "bounce" out.

In parallel with that, I'm planning to start this:



A PM Research number 4 - a bit of a bigger beastie. 1-1/2" bore, 2-12/" stroke. It's not a very "fancy" looking engine in a lot of ways, but is a decent size so should look impressive. I've read a few build logs that give me some good insight in how to proceed.  :ThumbsUp:
Stuart

Forging ahead regardless.

Oh wow.... that PMR is a beauty! I look forward to following your build log on that, not least because I have the castings for the #6 as yet untouched.

Also the lathe upgrade sounds great.
