Nice pictures and progress on the pump  :ThumbsUp:
Looking forward to some extended runs with the cooling system up and running.

To make the connection from the coolant outlet passage on the cylinder head to a radiator hose, I needed to make a fitting. I took the inspiration for this fitting from a thermostat housing.

The fitting is made of two parts:



To assemble the two parts, slight press fit and some JB Weld for good measure.



...and the fitting installed on the engine:




The next set of parts I made were the pulleys to drive the pump. I'll be using two O-Rings as drive belts.





The bearings installed in the pump pulley.



The pulley installed on the pump:




At this point is was time for a test run. I used a pulley I messed up earlier and had to remake, chucked up in my drill motor to drive the pump. I measured the rpm at about 750.



Thanks everyone for following along, and stay tuned for more.

Thanks guys for the kind comments! It's very much appreciated.

To have a way to tension the O-ring belts, I decided to build a dummy alternator.

For the alternator bracket and tensioner parts, which are somewhat odd shaped, the first side is machined. Then a set of machinable jaws are installed in the vise to machine off the holding stock and finish the second side.







Second side in the soft jaws:







The tensioner parts are tapped, and the slot is milled for the fork.





The alternator housing and end bell are finish machined:





Here the finished parts:









and the assembled alternator:





installed on the engine:






Thanks for following along, and stay tuned.

Hi Yogi,
Your Twin is turning out very nicely. Looking forward to see it in its completed form. You may still have time to finish it up for Cabin Fever in January. Hope you plan to have it at the show. Even if you don't get it finished, bring it along anyway.

Nicely done,  Yogi.

Functional, yet adds a lot to the look.

Looks good  :praise2: The next challenge is a working generator or alternator  :stir:  :) I think that the alternator might be easier without a commutator  :headscratch:
Best regards

Yogi,
The "thermostat" housing looks great, clean & elegant. The alternator bracket looks good as well. I assume you need to remove an end to tighten it? Or did you complicate it by left handed threads on one end and wrench flats in the middle. Everything looks great glad to see you back at it.

Jeff, no guaranies about Cabin Fever, but that would be a goal to work towards...

Roger,  :stickpoke: :thinking: :stir:

Art, yes, I have to remove one side to adjust the tensioner. I certainly contemplated a right/left hand thread like a turnbuckle, but decided against it for simplicity sake.
