New Boots

The “Truck” rallye’s I ordered way back in August are now, ultimately, unavailable.  So…. “Vette” rallye’s then.  And BFG’s.  Because Old School.

Fixed my Plasma TV

My Panasonic Plasma TV didn’t turn on.  Instead, it just flashed the power light 10 times over and over.  A quick Googling gave me THIS VIDEO that indicated which boards inside the TV were causing the fault, and what to do about it (two chips and a two 1uF capacitors).  A few other sites suggested it is only the caps causing the problem.

Since it didn’t work anyway, and since the extended warranty expired just last summer, I really had nothing to lose.  I happened to have a couple 1uF caps and a good soldering pencil.  I followed the video and took the thing apart, changed the capacitors, and lo and behold!  It worked!  Yay!

Surface Modeling

I’ve been using Pro/Engineer in my Drafting classes for about 7 years now.  The “Educational” version of Pro/Engineer Wildfire 5 is somewhat stripped down, and while Carnegie Mellon University had a sweet set of tutorials which I have adapted and updated for ~our~ version of Wildfire, it cannot do Surface Modeling.

With a recent computer update at our school, we had the opportunity to purchase the AutoDesk Design Suite (AutoCAD, Inventor, Revit, etc.), which has taken some learning but is very impressive.

I finished re-writing the CMU tutorials for Inventor 2013 and may upload them here shortly.  IN the mean-time, I was finally able to do some Surface Modeling, by creating a tutorial off of this video here.  Cool!

Vacuum Advance Limiter

For the HEI on the Crusty Chevy.  Currently running 20° base timing, 14° mechanical advance, 12° vacuum advance.  Once this is solid, I will change the power piston spring in the carb to stay closed at idle in gear (previously idling at 6inHg in drive).

Carbs are Easy

Just time consuming.

Completed all the tweaks, got it back together, and got it running.  Needs more Idle Bypass Air, so it has to come off again – but that’s easy.  Just time consuming.

Throttle Shaft Bushing Install

Rochester Quadrajets are notorious for worn throttle shaft bushings, which result in tuning difficulties, among other things.

I found some 5/16″ ID, 3/8″ OD bushings are my local auto parts store ($2).  I machined a cutter from 3/8″ rod which I turned down to 5/16″ long enough to pilot the center bushing in the baseplate.  I used a Zip Disc to cut flutes and back rake.  I tested it briefly, but chickened out and just milled the bushings with a 3/8″ end mill.

I will likely test the cutter out on another Rochester I don’t value as much…..

Tomorrow, working through Cliff Ruggles’ book: “How to Rebuild and Modify Rochester Carburetors.”
