Default Pulse XT 40 Engine Mount

I am assembling the Pulse XT 40.
I installed the engine mount and it is to wide by about 1/8"
I would like to get the rails closer together so there is more meat for the screws.
It appears I could squeeze them together to accomplish this.
Not an idea I am happy with.

Have others had this problem?
How did you handle?

Thanks,

Use a different engine mount.

Some engine mounts come in two pieces with oblong holes.

You can adjust the width of the mount while the actual mount hole locations remain constant.

See this: [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXJ772&P=ML]Click me![/link]

If that does not work you can do what we normally do.

Get a standard width hardwood dowel from a hobby store... say a 1/4" diameter or less dowel.

Cut 4 small pieces off squarely.

Tap out the existing Blind (T) nuts.

Epoxy the small pieces in so they end up FLUSH with the BACK side of the firewall ( you want the flush on the back as you'll not be able to get to that later! ).

Use a Japanese razor saw or sanding wheel to cut and sand the front side flush...

Mount the engine on a mount PROPERLY.

Put the mount on the firewall and center it perfectly and mark the location for a new set of holes.

Drill the holes and install the T nuts again.

Now mount the engine.

Except for the epoxy drying it almost takes me as long to write this as to do it!

Opjose,

I am familiar and experienced with the process.
Hoping to find some new ideas, I hate having to alter a brand new pane.

Thanks for the idea,

Get a mount that fits the motor , The motor is useless without one , or get a motor that fits your mount...There are adjustable mounts that would probably fit the firewall...Resetting the blindnuts is quite easy at this stage in the game anyway ..

Well, I found a 5/32 round file that fit the mounting holes.
I was able to elongate the holes which moved the mounts closer together.
I now have a slightly adjustable mount that fits perfectly.
(Why didn't Hanger 9 include an adjustable mount?)
The file was designed for sharpening a chain saw.
Consequently, it was not very aggressive and the process took some time.
The results were well worth it.

Thanks for everyone's input.
