Did have a mind to visit the Bristol show - is it soon?

This coming Friday

That would be a possible....

I'll either be: In the car park acquiring more castings  At the ICEBG stand sharing sticky thingies (assuming someone does not pig them in 2 seconds flat this time  ) or trying to spend my hard earnt pension money

Bit more work on the eccentric strap - had to machine a bit of chuck clearance into the tooling boss in order to cut the nut pocket.  Also ordered some plywood to make a base.

Hi Simon, nice family shot of the made progress so far.

Hello Simon,
Such good work.  I've been MIA on this board for a time, busy life these days, . . so I have a lot of catching up, and photo viewing, to do but eventually I'll catch up.

Thanks for the comments guys!  Slow progress of late - made hard work of machining the eccentric multiplier stand casting - it was just a pig of a job to hold and establish a datum.  In contrast whipping up a pedestal for the outboard bearing took hardly any time at all out of a piece of TB650 :-)

Time for an update - been mostly fighting with holding castings of late.  The eccentric multiplier lever casting seemed impossible to hold so gave up and machined it from bar stock.  The steam inlet elbow also proved difficult - tried holding it in the four jaw but couldn't grip it properly, then tried holding it in a small vice and the in the four jaw but again the grip was poor.  Solution was to tap the core holes M10 and then make an L shaped jig to bolt it to - was then easy to hold in the four jaw to shape the flange, and then move to the mill to drill the bolt pattern and swap ends and repeat the operation on the other flange.

That valve and elbow came out looking great! Nice way to hold the elbow, thats a tricky shape for sure.

I love what you're doing with those valves SCO.   I see so many engines with valves that are anything but prototypical.

Perfect

Nice work. Clever workholding......I'm enjoying this       Terry

Nice work Simon - I'd heard you'd gone down the bar stock route 

Love the valve too - looks very original 

Happy New Year to you and Wendy

Good thinking there = great result.

Took time this morning to review a lot of this project Simon.  You have done an excellent job on this model and your postings have been very helpful to me.  I have learned a lot following the project, especially about the problems associated with holding castings for machining.  Some of these problems could easily be addressed when designing the foundry pattern by adding an extra lump or bar to the casting that could be cut off after the part is machined.  It will be my New Years Resolution to add holding considerations to my list of pattern design parameters.

Many thanks for posting your work and comments.
