Thanks Muzz, I have really enjoyed making this cutaway motor.

This is the coolest!

I think the company I work at might like to have you do one of our machines. Certainly not as involved but might be good fun for you as well. High speed disk type centrifuge (Italian!)

Now the back half falls under the knife (well in this case a cut off wheel and sawsall). It's a leap of faith at this point...

I clean the rough cuts with an autobody file, the old fashioned steel serrated blade that screws to a wood handle, a hand file and a mini air driven belt sander. then into the vapour balster

Test fitted to the engine

Now just to clean up the transmission internals and put it together then paint the cut edges. This small motorbike hydraulic lift table may just ne the perfect display stand, a couple C clamps around the bottom of the oil pan to the table secures it.

Keep up the good work.

Well I think I am done with the cutaway motor / transmission, will need to make up a permanent and more stable stand, but the transmissions together and joined to the bike. I am pleased with how it came together and I think I gained a better understanding of the Guzzi drive line architecture, damn solid piece of engineering.

That's impressive and beautiful!

If you could find a pedestal like this for cheaphttps://www.ebay.com/itm/DELTA-ROCKWELL-MILWAUKEE-PEDESTAL-7-TRIPLE-DUTY-BENCH-GRINDER-STAND/113588229591?hash=item1a7262d5d7:g:0oYAAOSw~llcR25J or fab one up from tubing would be the hot ticket.

"Damn solid engineering." For sure, and a damn fine piece of work out of Canukistan..

I see the clutch plates made it.

Sure did, just this afternoon, Thanks for providing the last of the missing bits.

Thanks for the stand picture Rink Rat, that would be perfect, a great big industrial cast base, powder coat it and put a rotating type top on it! I need to keep my eyes open for that kind of thing.

I have had some 1/8" steel plates laser cut with the Guzzi text and logo, I traced over a jpeg in AutoCAD and sent the files to a fab shop.

These two sides will be joined with a 1" x 1" steel angle to a 1/8" steel base plate and I plan on making up an opaque white plexi-glass light box to fit between the steel plate sides and back light the logo and the underside of the engine.

Looks absolutely brilliant! Does it still rotate? If it does, you have to hide a small eletric motor somewhere and make it animate!

Thanks Rick!

Yep it still rotates, I am guessing that the generator could become a motor? What it would really need is a very low rpm 120v electric motor inside the generator case to rotate the engine. I thought about attaching a wheel with a handle like one off a milling machine but much larger diameter to the transmission output shaft and then rotate the drive line by hand. I have lots of work to do just to finish the base and the lighting, our local vintage club has a show in a shopping mall the last week of May and I want to have it at the show.

I finished the engine stand today, laser cut 3/16" steel plate, 1/8 Plexiglas top and side inserts. I will install a LED light strip inside the light box and run it off a 12v battery.

If anyone wants the CAD or pdf file of the side plates for the stand just send me a pm with your email address and I will share the file with you.

Muzz · « **Reply #74 on:** May 02, 2019, 08:29:51 PM »

That is just amazing Jim. A real work of art.

No Roper sloppage plate fitted though. This could lead to a lube failure.....

Thanks Muzz!

I will try to keep the cornering speed down

Those appear to be V700 timing gears, which have finer teeth than later ones.

That is an interesting observation Antietam. I thought they appeared to be a different pitch to "normal" ones. I reassembled a set with similar pitch back into an 850 T motor, from where they came, and wondered what their heritage was. I am sure you are aware of the inability of a factory gear set being assembled into a chain motor due to the oil pump shaft end & centre distances being different. The crank gear was a shocking fit on the crank, I had to put a hardened washer behind it to work properly on the bearing thrust face, the cam gear was simply loose on the shaft & the oil pump gear needed a washer on the front so the nut would not threadbind. It has a billet high volume oil pump.
Here they are here;

Great work maestro!

Here's one I did in 1980 by hand with a hacksaw & file, in the lounge of a little flat I had with a Canadian chick. We split and she was surprised to see it finished when we got back together after a 20 year break.

It now stands in our front door entrance.

Great Job Canuck750, that is indeed a masterpiece. Sending you a PM also for that CAD file, thank you for offering it. You picked IMO the best version of the guzzi logo!

dguzzi · « **Reply #79 on:** May 03, 2019, 08:23:01 AM »

Our company would love to have one of our machines done like that, for a lobby display. But I'm sure they would freak out at the cost. Even just for the rotating part would be cool as heck.

Thanks mate, awesome stuff. Bloke here down under cut a section out of a 5 speed because he couldn’t get it to shift right...

This has been very enjoyable to follow along. The finished product is worthy of display in a museum IMHO.

I look forward to seeing your display base lit up.

That looks 'orribly like an Ajay/Matchy twin pushrod.

Break it's crank did it?

Sounds like we have some discussion time at the Tattley Rappet this year.

Roy gardner · « **Reply #83 on:** May 11, 2019, 03:50:37 PM »

Correct Muzz. No, it didnt break that crank, just blew it's aluminium rod out and ventilated the case as they do. The crank that is in there is "twisted" around the centre main bearing according to the reconditioner who I asked to grind it. That appears to be a contradiction considering that cast iron is so brittle we dont generally imagine it having the ability to "twist" without breaking.
