(16) Engine Mount ( Mike)

Hey Guys,
.
.
For a Stock Mount.... Watch Earl's video... it should help...

When I bought my engine , it came with the mount.

The dynafocal mount was on a stock Cessna 152 ...

So I set-up "the Board".... The same one that has been used to mount the Bushings on the Fuselage...

Then used to match those holes for the Landing gear mount....

I mounted the landing gear back on the board.... My lines and Datum have already been drawn...
.
Since this isn't a fresh start.... I simply positioned the mount where it goes...

I'm center on the Datum , and I've measured the distance I need from the board...

My Oil Filter will have 1/8" clearance ( UNSCREWED) from the Firewall....

The 0-235 is a heavier engine than the stock 0-200 per print... So closer is better...
.
After Height and position have been figured out.... I secured it in place with some all thread and a 2X4

This held it SOLID while I fit some tubes...

I'm mounting it like Jim Clement does on his Tailwinds. It looks like a Strong Mount.

Note the curve I put in the lower tubes to get surface to surface welds....

DON'T DO THAT...... Well, don't do it like I did....

You'll need to put that bend in it.... But cut the tube at the bend... The surface can be welded...

and there is no bend in the tube....

Hey Guys,
I've got 3/4" tubes as the Main Structure , Then 5/8" tubes... These are a heavier wall , at least .049

All I had in 5/8" was .058 , so I used it...

After everything was tacked up good , I cut away the old mount.

Hey Guys,
Time to check "fit-up" , also I need to check clearance for a couple of tubes...

I put the mount on , and cut my other tubes and marked the location...

Then I had to clean up the area before tacking them in place... ( Back on the Board )

Hey Guys,
Everything is tacked , and looking good...

At this point , I mounted it on the Fuselage , and welded everything I could...

That would hold it better than bolting it to the board...

Another "note" , It's always good to know which way to "Favor" something....

Yes build it the best you can... But if it doesn't end up PERFECT...

Favor it pointing to the RIGHT....
.

Hope this helps...
