Ah, I didn't realize you built the Elidir engine. Mine is the Milner design. It is not as close to prototype as the 3" designs. The firebox part of the boiler doesn't stick up to provide steam space but it fires well and has not primed.Steve Goodbody wrote: ↑Mon Jan 08, 2018 6:23 pmHi Fred - I can't remember if your loco is the Milner or Don Young 4 inch scale design? I've heard that the valve gear on one of these designs can benefit from modification but can't recall which one. The valve events on the Elidir design seem good while bench-running on air, time will tell how it performs on the track however.
The notched lever is the steam brake valve - it's a modified version of the Martin Evans progressive application design for Highlander. The original design uses a rotary handle, I've modified it to a more prototypical-looking pull to apply, push to release version.
