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.

  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.


Paul Lamar


It appears from the makco chart that 580 and 590 join at the base of 675.
What puzzles me is the image of the brown part of the damper plate assm. in
your rhino rendering showing internal splines, with no pilot shaft. I guess
this means Tracy cut the splined extension off, thereby opening it for the
shaft from the planet with pilot extension.

It is confusing if you hav'nt seen one before. I'll visit the trans shop on
monday, or go to PYP for a one day e40d trans class, and just take the whole
thing apart.

Ed Carver

Well I just did not draw it in. It is on every part that Tracy shipped.
It pilots in the end of the e-shaft. It would be great if you can find
one. I have two of Tracy's boxes in the hangar. One belongs to Milo
and the other is in the RV4. I would rather not take them apart.
