    As big a fan of EVs as I am, I would have a hard time wanting to convert an older car.  Though it seems relatively easy to mount an electric motor to the front of a conventional transmission, that is only the start of the problems.  You have to add 1000 lbs of weight to the car for the batteries - which of course requires changes to the entire suspension, braking, steering, etc.  Speaking of brakes and steering, they then need to be converted to an electric system.  And if it is a more modern old car, an electric air conditioning system needs to be devised and so on.  It would be a never ending project.

     

    I know a fellow who converted a Porsche 914 to EV.  He has been working on it as a hobby for over 10 years.  I was amused at his cabin heating system.  He found a couple of womens hair driers that would work on DC.  Wired them in series to match the battery voltage and they then blow hot air through the HVAC ducts.  (No need for cooling as he can just lift off the roof.)  He also did a lead-acid to Li-ion battery conversion a few years ago - which added to the costs, but also gave him a lot more range and usability.  While it is quite driveable, it is definitely still a "work in progress"...

    Guess the one thing I've learned and been taught in life is "electricity", (AC or DC), it has it's advantages and faults as well. Case in point, (thank God for Big Ben alarm clocks) power is out in the morning, no lights, no heat...5 oil lamps get lit for showerin' and shavin' and a log or two in the stove for heat. As far as vehicles go, there just isn't a charging station deep in the Gila Wilderness, places I enjoy beyond civilization.....They'll just have to impress me beyond fossil fuel....

  2. If the foundation is solid the rest can be rebuilt ....and whole lotta fun to drive. I had a '60 Willys back in '80, it was geared low with the F4-134...45 mph downhill with a tail wind. BUT, would climb a wall in low range ....so much fun.  Kaiser Willys is gonna love you  if you choose to get it rollin'.

    I will file a complaint against him, even if I live in France, it's not a problem

    The internet is a powerful tool... report it to "Ripoff Report".....If you have a name and address to which you sent the money contact the local DA's office and report it to them. If everyone that has been scammed reported to law enforcement (DA's office) it will become a file. Sooner or later this SOB will do it locally and be arrested for Deceptive Trade Practices. Being as you are in France....Mail Fraud will be on the table as well and that's a Federal offense!  Watch your back and each others and take out the TRASH!!  Bastards like this hurt me as well just trying to make a living and doing what I do best.

    Foundry pattern makers used the shrink rules to make the Master Patterns which obviously have larger dimensions than the blueprint show net shape desired.  This is a "two shrink" scenario (master pattern-to-production pattern-to casting desired dimensions).

    I recall a few times over the years when replacement casting issues from folks came up here.  They wondered if they could take an existing casting, clean it up, then have a foundry use it as a pattern.  Well they did not know that the iron would shrink to below the desired net shape.

    Yep, master patterns were sent to an aluminum plate manufacturer and reproduced in single or gang configurations using plaster molds, 1 shrink...molded at the foundry in sand 2nd shrink. they were designed for high repetitive production generally on squeezer and Hunter 10 and 20 molding machines. Long ago they even used Magnesium to make the plates. 'Bout the only casting you can cast from itself would be cast in Ductile Iron, shrink lays in at 1/10 of an inch per foot...ok for small products with no machining involved but larger and machining needed a new tool is required. Gray Iron sits at 1/8 per foot and the numbers just keep going up from there for all other ferrous and non-ferrous metals. For the last few decades my shrink rules sit idle, I prefer to use dial calipers and convert into thousands of an inch...it keeps the tolerances closer to +/- .000".😉

    You knew someone in the foundry business? Not many people know what a shrink rule is for.

    Yup, me.... 40+ yrs a Journeyman Pattern and Model maker. Got lots of steel ones too. Starrett and Lufkins. LOL, not many know what I do, seems when I tell them I get the "Deer in the headlights" look!

    My sister did the ones in my 30 Cadillac exactly how the original ones were sewn. Three sides by machine and the side where the arm is by hand. Plus made me dinner while I waited is a deal you can not beat.

    I just noticed I never replaced the screws to original ones.

    Screw the screws...your sister has a blessed talent....recreating a 91yr old skill is her gift! Lucky you!!

  7. Cool Thread....I grew up with Bach and Beethoven playing in the house...My mother played it on the piano like a symphonist....sang like Julie Andrews too.  Music = the moment for me....If I'm tweeckin' it's soft and slow....If I'm installin' it's "Rock On"!  ALL music has a moment for every occasion! 

  8. Hi Ken,

    Don't cut just yet. First take some measurements of the casting and jot them down, they are actual to the part and period. Second, if you can, make a "jig" from wood and bondo and secure the casting (wax it first) to the wet bondo and wood. This will give you a fixture to epoxy the casting back together filling "just" the saw lines. Castings are like a solid print, exterior first and interior second. You are going from iron to bronze so the shrink will be different and measurements will be critical. I did a "Thomasnet" search and didn't find any bronze foundries in your area. You might try a yellow pages search of 'Frisco and Oakland and see what comes up, there may be one not listed on my search.
