I have a quick question for the engine guru's here.

Ok.. I have an O-470-A core. I have an engine mount, for this project that is set up for the o-470-A/J (I think).

I have an IO-470-S, engine. What are the chances that the engine mount ears, from the o470-A, would bolt onto the io-470S (The s is currently installed in the starduster ii, and we don't really want to pull it, to figure this out.)

I don't know much about the differences in o-470 continental engines. Would this make the io470 fit onto the engine mount that i currently have, or would i be better to come across a Cessna 180 engine mount, and change the legs so that it could be installed on the front of the poorman?

I spoke to a guy named Cooper from central WA at Airventure this year. He holds the STC to put the 470 on the Stinson. Although you're experimental, what I learned may help.

I believe that it is possible to put the mount ears on the IO-470 and it will bolt into your mount.

The STC uses the old style mount, and he tells me there can be a lot of movement in the old style rubber bushings that go in the saddle type mount from the early 180.

With the extra power and torque of the IO-470, you may have more deflection of the engine in the mount than what you'll want to tolerate. If you can get or fabricate a mount that will use the rubber pucks and later style mount ears you might be happier.

My 1953 C180 had the 470A engine until 1993, when it was replaced by a 470K.
They used the original engine mount, but they had to pull the mount "legs" off the old A engine to do so.
I've heard the later style rubbers are a better design

So it sounds like I can move the ears from 1 engine to the other. . But the words of wisdom are to change the mount to the new style of fittings because the new style is sturdier.. . Good thing I got a year or two to figure this out.

Thanks guys

Try Acorn Welding in Edmonton. They have a jig for nearly every mount. They might be able to fabricate something for you with the 180/185 mount up front, and matching Stinson mounts at the rear. Hopefully they can offer better prices for an experimental mount than for a certified mount. They aren't cheap!

They could also have some damaged mounts that they'll sell you for parts. I believe that their repair procedure could sometimes involve replacing every part on the mount, although they are only certified to repair, not to manufacture.

"Repaired hammer by installing new head and new handle. OK for return to service."

Feeling guilty. . Didn't work on the plane today. . Decided to hitch a ride to a few gravel bars

Saw that plane for sale a while back, looked really, really nice. I didn't realize it had made it North!

One of my friends bought it maybe 6 months ago. . I helped him get it imported. It is a nice machine but he wants to do some modifications after his hunting trip this fall. . He wants to get rid of the bungee chords and a few other little things

Which bungees? Are the aileron-rudder interconnects still in there?

The suspension bungee chords

He wants to put some big shock type of gear on. Like the just stol stuff. Preferably taller also to get a little better angle of attack.

Ah, gotcha.

First landing for my stinson on a gravel bar.. thinking I need a little bit bigger of tires

Haven't updated much... been so busy working on other people's projects.
The bullet went on a diet this winter.. new landing gear.. new tail wheel. Repaired almost all the tubes in the tail... just about done this project for my friend.. I basically did the supervision and arranging parts/people etc part of this job.. I wish I could take credit for the skilled labor.

Landing gear has 20" of travel.
