Aaaah, yes, the Angela&Alex kit.
Hello Charlie, thanks for reading!  :bow:
I received that same attachment this weekend and tested it out.  I don't have a strong enough pressure washer.
The soda flow was intermittent and when it flowed, it quickly clogged.
I found a video from Eastwood advertising a similar nozzle and they recommend a 3.5gpm rate. https://www.youtube.com/watch?v=ws3OrpR4CvE

Then I added the blasting gun and had it siphon the media into the water stream.  It flowed consistently, but baking soda is not abrasive enough.  No stains came off.




So, today I bought a box of glass media, which I will use dry first since it's easy to recover... we'll see.
I can't wait for the weekend again!
Meanwhile... I am getting drunk on vapor blasting videos and tutorials.

Pescatore:
I finally got to try the glass beads (40/70 grit from Harbor Freight), but without the appropriate blasting cabinet I would have to disperse
a bunch of glass dust all over my yard.  So, I wrapped the engine in a tarp, stuck the blasting gun inside and hit the engine blind.
The media worked well, but it was turning a shade of brown... pieces of the tarp.
Here are the usual before and after....


 


...and the crowd goes wild!  :rolleyes:

At this point I had to build a blasting cabinet, but didn't want to invest time in that.  That's a winter project.  I decided to improve on the tarp idea.
I had a roll of 6mil plastic
thin plywood
banjee cords
a piece of plexiglass
a bucket
a section of ventilated shelving
a 2x4 stud
a 12" swivel bearing: https://www.lowes.com/pd/Richelieu-Swivel-Plate-360-Degree-in-Galvanized-Steel/1000818576
2 saw horses
a mini soccer net
the inevitable duct tape...  Nah, Gorilla Tape!

I bought these blasting cabinet glove ports: https://www.amazon.com/gp/product/B07XGFZLP9 and gloves https://www.amazon.com/gp/product/B077YP72SP
These rings are overpriced, but work great.  I attached them to a piece of plywood, insulating the front (was not necessary) and taped the back.  Gorilla Tape is my new friend!






The gloves are not really for a cabinet.  Maybe some other dirty/wet job.  They reach past my elbow, the end cuffs are too stiff and my hands sweat too easily.  Oh well.
I attached the gloves to the rings with 7" hose clamps from Home Depot.




I cut two rectangular openings in the plastic.  I stapled the gloves panel below and taped the plexiglass above.



Who needs a cabinet, when you can make a tent?

I rested the engine on the ventilated shelf with the 2x4 under it, on top of the saw horses.  The shelf is too weak to hold a
113lb engine and makes it difficult to move it inside the tent.
I had seen blasting cabinets with an internal turntable, but the lazy susan did not work well because the engine is long (transmission attached)
and the tent is not deep enough.  I had to put the engine on a piece of 3/4" plywood, over the saw horses.

The plastic is under the plywood, shaped into a funnel and into a bucket.
I fed the air and media hoses through the hole for the bucket and had a... blast.
The media doesn't easily flow into the funnel, so I have to unwrap the tent and sweep the media into the bucket.
I covered the plywood with plastic, so it's easier to sweep.

The media still does the job after I recycled it 5 times.  Is there a limit?

Oh yeah, the bunjees and the soccer net?  The bunjees hold the tent closed and I used the frame of the soccer net to prop the tent over the engine.
One more day and I should be done with the engine.

What to do about the final drive box?!?  I can't blast that.  It will never spin again!  :undecided:

Pescatore:
I finally got the engine all clean and polished.  This is the end result of a whole summer spent stripping and blasting.


 



I started the assembly process a few weeks ago.  Reattached the gear box, rear drive and swing arm, rear tire, carburetors and air box.
The gear box shifts ok, so at least what started this project seems to be fixed.
I also attached the lower frame rails, but took them off to prevent scratching.  I still have some thing to check before full reassembly.

huub:
nice results!
anybody who ever tried to get a guzzi engine back to bare metal will appreciate the amount of work...
I am lucky i have a specialist who did my le mans  engine,
blasting the engine and box it is the only part of the Restoration i did outsource.

Pescatore:
Thanks huub.  Having approached it from the cheap, I ended up getting the right tools for the job.  That's when I made real progress... not that I would want to do this again.
I did some more cleaning after those pictures and sprayed it with ACF50.  I hope that's enough to keep the metal looking nice.
