That is looking a lot better Jean.

Make sure the prop flange is the same as one of
these SAE standards. The big one is for wood props
and the smaller one for CS props.

I PAUL
I FOLLOW YOUR RECOMMENDATION TO DESIGN WITH NEEDLE BEARINGS
AND I CAME UP PRETTY GOOD BUT I NEED YOU TO LOOK AT IT AND
COME BACK WITH YOUR RECOMMENDATIONS.
I AM SENDING YOU 3 2SHEETS WITH DIMENSIONS


Jean Prudhomme

If your drawing program can export IGES or AutoCad DXF files send me
 those
instead so I can import them into Rhino. STP (STEP) files also work.

It is best to send the individual part drawings with dimensions rather
than dimensions on the complete assembly. Too confusing.

I don't need the part drawings on the Ford planetary parts
as I have those in Rhino dwgs already.

Once you have it in Rhino you don't need to send dimension
at all. All you need send is the Rhino 3DM file.

Paul Lamar


Paul all the file are in IGES and i try to transfer to george Grimes
and he can open it.

I still working on the full design and i added a snap ring on the
front to hold the front seal,i will have to use 2 check valves to
prevent the high pressure to interfer with the low oil pressure.
I should start to design the separate parts soon and i will forward to
 you

Here is a preliminary Rhino rendering. It will take a lot more
work. The prop flange spline may not be accurate. How many
spline teeth are you planning on Jean? It is also not clear how
you are going to retain the flange on the spline.


Paul Lamar


 Good afternoon Paul
 The flange will be secure between the bolt,s flange and the
 reset on mainshaft, i am looking to add a small portion of taper
 at the end of the flange and the shaft  for a better tight fit
 when main bolt will be torque, a special shaft with same spline
 as the planet to be machined and will be welded to a steel flat
 bar as a tool to hold the shaft at the moment to torque the prop
 flange bolt

 I added a snap ring at the front to prevent the seal to coming
 out.

 I know your idea to machine the front planet and attached to the
 inside flange flange shaft ,but my point of view it will be less
 machine work and cost to machine the whole planet with the shaft
 and it will be easier to mount the planet gears and will be
 stronger and it will be one pce for lateral movement.
 For machining it can be first drill sideway at each gear close
 to the size and be finish with small end mill bits
 ,those gears shaft head can be pressure fit without driss pin
 secure .

 Just an idea.
 With my design it will be less expensive and easier to replace
 the planet ,the inside flange can have pins with  the planet
 surface to increase the strenght, it,s already 6 holes of .250
 for more oil feeding but can be use for pins between the shaft
 flange and planet

 Here is what it would look like with a housing made
 from thick wall tube and plate instead of the mini sprint bell.

 There are two tube sizes needed. Four inch dia. 1/2 inch wall
 and six inch dia. one inch wall. The four inch can be bored
 out of bar stock as I found a shop in SZP with a really big old
 lathe than can drill 3 inch dia. holes in 4 inch dia. bar stock in
 one operation. You weld everything together and then machine it
 to final dimensions like Don Dunbar did on his gear box.
 Don'3 was a bit over kill as far as thickness's were
 concerned. I also don't think the webs are required but
 they can be welded in with no trouble.

 This would be better than the mini sprint bell as the 6" dia. section
 that holds the ring gear can be made long enough to accommodate
 all the thrust bearings required. Just like Tracy's box.

 Also it will fit Jeff's stock motor plate.

 Paul Lamar


Paul, I have a couple cast housing, 6061 T6 like in picture 6 from an old
experiment that i will send if you like. Give me the dimensions and I will
measure them up. no charge.

milo

Thanks Milo
That one is about 5 inches long and six inches in diameter.
I'll send you a shipping address by private email.

-------------------------------------------------

I got it Milo thanks. How many castings do you have?
I think we can design a box around it.
ID is about 3 inches and OD at the mount end is 5 inches.

BTW when are you heading for Texas?
