This bowl lightening all started out when a customer absolutely had to have the lightest jet pump in the world.  A titanium shaft was procured, the ball bearings in the thrust bearing were replaced with ceramic balls, and the impeller was lightened.  I was tasked with finding a way to pull the most weight off of a Dominator bowl possible.

I wanted to have cool race parts on my boat too.  I reverse engineered my Berkeley G bowl, the same way I did the original Dominator bowl, with just a test indicator and a mill equipped with a Digital Read Out (DRO).  I generated a drawing in SolidWorks from the point that I measured.  I did this for every surface that I could reach, inside and out.  In some cases, I had to make special styli to reach into the curved vanes.

I like to try to learn something new in everything I do.  For my bowl, I wanted to push my limits in SolidWorks and my CNC programming.  I have never really liked how the cradles attach to a Berkeley bowl and I hate installing them even more.  While working with Beerjet, we came up with an idea of integrating the cradle into a spacer.

I wanted to also integrate the bowl plug and vane extensions into this spacer that would extend back into the droop for water control, but I didn't have the time nor the guts to machine out 7/8" of my bowl vanes, potentially scrapping my bowl, and fit new extended vanes.

My intent was to come up with a design totally unique from what I had done in the past as well as what the copycats are doing.  The contours are all elliptical radii, blending the spacer/cradle into the original contour of the bowl.

The bowl and spacer/cradle were modeled as one so that the contours blend seamlessly.  The single model was then cut into two separate part detail models, one for the bowl and one for the spacer/cradle.  The two separate detail models were then inserted into an assembly model.

The assembly model was imported into MasterCAM and code was generated to machine both parts assembled together.

That is awesome. I love the spacer with the ride plate cradle. 👍🏻 nice work Joe

Sorry Jim, I just can't take less than the customary SCJB offer of a candy bar wrapper and a half-empty beer with a cigarette butt in it, I got too much invested.

I intended this idler pulley to be my crown jewel.  I have been dreaming of this for many years.  An homage to my favorite Halibrand five-window mags.

Drilling operation to rough out the windows.  Surface high-speed roughing with 1/2" ball end mill.  Surface high-speed finish waterline with 1/4" spherical end mill.  Surface high-speed finish radial, .001 step over.  Before polishing.

This stuff is awesome, amazing work Joe, keep up the good work

Thank you

Amazing work! Now I get it, Flusher is Joe from B1.

Top notch work Joe, I still get compliments on my Ford rail kit that you and Chris made me. 

Indeed.

Thank you. I enjoyed the opportunity to work with a Ford.  Hope you are keeping up with your machine shop classes.

Cheers,

Joe

Awesome work Joe.

I'd get that idler trademarked or you'll be seeing Chinese knock offs available at Summit soon.

Awesome work Joe  so clean
