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, 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.

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.
