Hi Per - yes I think I've surprised myself with how much I've enjoyed picking it up again. Novelty hasn't worn off yet so theres still a bit more to come - who knows it might even get finished  ;D

Good to hear from you, how's that new mill going?

Hope you are well, we are still ticking over nicely despite the restrictions.

Sue sends her regards too,

All the best - Tug

Great to hear that you enjoy making parts again  :cheers:

I'm sure that the mill is doing fine, though it might be a bit bored as I only had found time to correct the T-Nuts for it and repairing some parts for my Off-Roader winter bike so far ...
But I have promished myself that the first model engine part done on it will be the piston pin hole and weight reducing milling internal to it, for a new Viking (and the old one too)  so I can get it to run as it should.

I'm doing fine, if rather busy with (as usual) way too many projects and unfortunately with higher priority than model engines ....

Thank you to you both and best wishes

Hi Per, I shall look forwards to that Viking in due course  ;)

I've been picking away at the trip gear parts - all milled from cast iron and small amouts of JBW to give the odd fillet here and there.

Though I have found the drawings to be good overall there are some slight discrepancies in this area but with some careful jiggling and countless take aparts and reassmblies I'm getting there.

Here are a couple of pics of state of play as of this evening

The HP valve rocker is finally linked up which served to highlight the fact that any adjustment finer than half the thread pitch is out of the question. A 5BA LH tap and die is on order to rectify this situation.



The exhaust linkage had to be rearranged for clearance on the inlet linkage. New pins are required hence the loose parts



One of the things I overlooked when changing the steam stop valve to top mounted as opposed to floor standing was the bracket for the govenor linkage. I think I can get away with this by putting a spacer underneath the valve.

That's the latest - still the inlet valves and spindles to deal with plus more linkages  ::)

Regards - Tug
