Right!? Me too!
and they are finished, 46 Speedo housings including steel thrust washers
in the attached photo, front 3 have been media blasted to remove machine marks, middle 3 have thrust washers installed but straight off the CNC, rear 3 still need thrust washers installed
and a box full of housings waiting to be unpacked and prepared for shipping

Just a thought: as the original ones are polished, wouldn't it be nicer/easier to polish these, too, to remove the machining marks? Thought about that, too, for the clutch cover I bought from you a while back... ;-) Just need to find someone with a good mask and tight googles to polish them... ;-)

If they are up for grabs I would be interested in two media blasted ones.and they are finished, 46 Speedo housings including steel thrust washers

yes, they can be polished no problem at all but will not be me doing the polishing, not a service I offer
yes once they are all assembled and prepared and posted to Canada, Austria, Scotland and West Aussie I will have 11 left here in stock

Excellent work Red. The amount of work you do to support Laverda is astonishing. Just a few more CNC patterns and you'll be able to build new bikes from scratch!

another Redax billet part coming to market but this one is a bit oddball, only a few people worldwide would be interested
our favorite CNC guru just made a short run of custom billet lightened and modified 750 inner crank webs to be used on Twisted 750 crank webs
needs a custom center pin as well which is shown at the back
we decided that trying to source 750 cranks was becoming harder so why not just model what we need and machine the fuckers from billet, outer webs will follow next year as they are also becoming harder to source in good condition
Extra hole near the circumference is for Mallory material, part of the crank balancing procedure

750 cranks off to be balanced tomorrow, lightened by 4kg, billet steel inner crank webs, new Oil slingers, custom made Crank pins, new bearings, Nitrided Crank webs
Machined up yet another crank fixture
crank press
Use Rotary table to turn crank to 90 degrees, clock exactly 90 degrees using Digital readout on X/Y axis
Start pressing with pull down bar to be exactly in the right point, transfer to 55 ton Hydraulic press to finish pressing
Crank press 1
Three centers pressed up, 2 off to West Aussie, one reserved for Spain
Crank press 2
Looking flash as black on black

your crank is the one in the front without the outer webs
need your actual crank to be able to machine them to shape, though have been considering doing billet versions of the outer webs as well
maybe next year as our Laverda world is running out of crank webs

If you do the billet ones, I would be up for that, otherwise, you will have my crank when it arrives in the engine

That un-finished crank immediately reminded me of a Scott Flying Squirrel crankshaft that has the big end pins cantilevered off the flywheels.
Exceptional work there Red. It makes me wonder whether anyone else is putting this much R&D into re-engineering other brands of old motorcycles. The only ones that come to mind are the Horner brothers with their Irving Vincents, but they're not making their engines available for Vincent enthusiasts to buy.
