I keep coming back to this design for that and other reasons.
    Also because it can be retrofitted to Tracy's gear box.
    The stiffness  of the silicone blocks can be almost anything.

    Not because it is my design :)

    Paul Lamar

    Paul, I am willing to do some of the leg work getting these parts
   made if
    you like. Industrial metal supply is a few blocks from where I
  live,  they   can cut most of it. Plenty of other cutting options
  nearby as well.

    And to get a prototype made, I can weld it up too. Have an 84
   syncrowave
    waiting for a job.

    Ed Carver

    Great Ed go for it. I think there are some laser cutters in your
    neighborhood.
    I am in the boonies when it comes to industrial stuff. Are you up
    to speed on Rhino or Solid Works? Most laser cutters guys can take
   Solid
    Works
    files. I can send Rhino files that will load into Solid Works.
    Mazdatrix sells suitable ring gears. Does Industrial metal supply
  sell   4130   sheet?   Use a .090" for the flex plate. A bit over
  kill IMHO but fine for   a test prototype. I'll test it on the RV4
  after I get a few hours   on it.

    You might want to make a prototype with cheap sheet steel to be certain
    everything fits on a counter weight.

    Get all that want them to send a deposit. Let me know what you
    need and I will send a check or cash your choice.

    Paul Lamar

    No rhino yet. I have Industrial metal working on a quote for the raw
    stock
    .090 4130. They do water jet and will take one of your rhino files
   maybe.
    I
    will be down there tomorrow to purchase the 1 inch tube for my engine
    mount.

    Ed Carver

    OK Ed. Let us know what they are charging for 1 inch .049 4130 so
  we  can   compare   prices.

    Check with IM and see if they can accept IGES or stp files.

    I can send them to you and you can give them a DVD or thumb drive.

    Paul Lamar

    They will take stp or iges.

    .090 4130 3'x12'=$525 I figured it is a little more than needed
  to make   20   parts.   They did not stock .050 4130 one inch tube,
  so I priced what they did   have;   .065 x 30 feet=$130

    They do water jet and laser cutting. Contact Terry Hill:
    thill@imsmetals.comHe apparently is the programmer for the lasers.

    I will, as usual, price this stuff elseware, IMS has usually been
  less   costly compared to other local vendors. They do discount for larger
    orders,
    and business accounts. Which does'nt include me.

    If the .050 tube is more than sufficient, I will us it for sure.

    Ed Carver

    I would go easy on the quantify of material bought  until we test
  this   thing.

    Try .049" perhaps somebody is not reading the list properly.
    Yes the .065" is over kill for the motor mounts  and too heavy.
    I have to leave in a couple of days for a week in Reno so I will
    not get the dwgs done until I get back.

    AC Spruce is not bad on cost.

    Paul Lamar

    I need to make a trip to ac spruce to get epoxy, etc. I'll pick
  up a  12x24   piece of 90 thou plate, it's about $30. I can make a
  prototype out of   cheap   stuff from ims.

    Ed Carver

    Great Ed.

    The splined plate is made from  part 675 in this dwg I think but
  I could   be wrong.   You might want to get one and find out. I'll
  see if I can get one when I   come   back from Reno if you can wait.
  I think Tracy adds a short cylinder  to act   as   a pilot in the
  eshaft.  I know it is not a stock manual transmission   clutch
  spline. The 2.85:1 planetary gear set is part number 582 and the sun
  gear   is   612. Ring gear is 592.

    Paul Lamar

    The 675 center shaft appears to be the only thing that the forward
   planet
    can ride on. So without seeing it, the back side of it must have the
   female
    splines. The brown part you drew shows the end removed but I am
  not  sure why   sense I have never seen Tracy's unit on the bench.

    Discussion has been made about creating a lighter psru. It
  would'nt  bother   me to begin to work on getting this done. If all
  it is' is getting  lighter   smaller bearing assemblies for front
  and rear, then we just need to  create a   new housing to hold it all.

    Where do I go to get the parts? Is Makco the place? I have a lot
  of   transmission shops nearby, that is why it only cost me $75 to rebuild
   my MPV
    Ford transmission clutch basket assembly. I have a 6 pinion planet
   set saved
    on my ebay page. I just don't know about the rest of it.

    Ed Carver

   Here's some ebay items for the center shaft:

   Hi Ed;
   There are several versions of that C6/E4OD/4R100 center shaft.
   At least 1 version has a center pilot extension on the splined end.

   The ones I have seen have a large bored cavity in the non-splined end
   (red in the image)
   I don't believe there is enough material to add a sun gear,
   although I have not checked the specific sun gear part you are
 considering.

   I'm guessing Tracy has his shafts custom made with the correct spline.

   Cheers
   Cary

   Not custom made. Some part from some automatic.

   Paul Lamar


I'm gonna search for the correct part. A few clues as to where would help.
I'm not sure what the part looks like. I could use a spline count, diameter,
and other  features of the part.

Ed Carver

The spline is 1 inch OD with 31 teeth. It is most likely 675 and it mates
with 555 or 554 in the Makco jpg. If you print this jpg and take it to an auto tx shop
they can probably verify. Part 61 in the Slauson E4OD jpg.
The male part is part number 420 in the Slauson E4OD jpg.
Each company has a different numbering system. Sometimes the parts
are shown stand alone and some times they are shown snapped ringed to a mating
part. Just so you can be confused.
