Nice covers Simon.

In your last photo you have something between the cylinder cover and chuck.  Is that what they call a spider?

Thanks Kerrin and Vince.

Vince - they are not a spider but four pieces of setup shim that I have recycled from work.

Hi Simon, I hope these suspension set up shims will have been already in a Parc Ferme.
Very good idea to recycle these parts.
The designers I have met in my life, took every opportunity to change the shape minimum yearly.

Made a little jig to hold the studding in a vice on the top slide and then used a 0.2mm slitting saw to chop lengths off in short order!

Next job was the valve rear covers, to try and get them all the same I bonded 4 lengths of plate to a bar and then machined them side by side to the same dimension in the dividing head.  Used a corner rounding end mill to knock the corners off then into the vise to drill the bolt holes.  Tidied up the flange thickness in the lathe and then slightly tapered the boss for visual appeal.

Hello Simon,
This morning I logged on to MEM for the first time in years and was surprised to find your L&B Corliss project.  Even more surprised at the progress you have made in such a short time.  It seems like it was only last month we shipped the castings to you.

The work in your photos looks excellent, and I really like the extra details you are adding.  I will be logging in more often from now on to follow your progress. 

Thank you for posting your work and sharing your experience with everyone.

Dennis

Thanks Dennis - It's great to have you and Jeff following along.  I've been impressed with the quality of the castings - minimal porosity and they machine beautifully.  When I get to the engine frame expect some questions coming your way as I can't work out which end to start from at the moment!

Trust you are enjoying a peaceful retirement, best wishes,

Simon.

Next is the valve bonnets - plan was to use a similar technique to the rear covers, so drill and shape some plate and then turn a conical boss to be bonded into the plate.  I left a tiny radius at the end of the cone to give a hint of a fillet where the cone blends into the plate.

Very nice!


How are you bonding the cones in place? Loctite, solder, other?

Loctite 648.

Did think about solder, again to generate the fillet radii more than anything, but there is much less clean-up with 648 :-)

Jeff - I have a couple of ideas for the crab claws, one of which is to cheat and get them wire cut.

Chris - Flywheel is 11.5" diameter, overall model length is 22"
