I have a jetcat Roo mount and need some ideas from others who have used this mount. What hardware did you use and how did you prevent the mounting screws from hitting the turbine casing?

Thanks in advance.

I mounted my Simjet this way on my Roo, same size as P-80.

I used a metal plate to prevent the screws from touching the engine.

Hope this helps.

PS: Don't use the doble side tape that you see in the picture, no need for it, it's a pain to get it off the engine and mount.

I wrapped several layers of glass around a can the same size as my engine casing. The cut my mount out of the ring, used flush head screws to attach some cut off hose clamps. Mount gets glued and screwed to the fuselage... Simple, reliable, cheap and aesthetically pleasing

I don't have pictures handy, but the JC mount is best mounted with counter sunk screws-in the UK we used M4, but 6-32 CSK if thats what you get.
You will not get the screw heads completely flush as the ali is not thick enough.
To protect the turbine case I cut a strip of 1/32" ply wood the same width as the mount and around 4-5" long wrapped around to allow the screws to "locate" in its thickness.

HI, I also used stainless steel countersink screw on my ROO, I am also using a JetCat mount on my Kj66, but what I did also because the mount is alum. so it is easy to conform, I stamped the holes to give a counter sink fit, so the screws will fit flush, I beleive I used an old punch, I ground down to the perfect fit. Also on the fuse, drill a counter sink to match the mount contersink. Now you will have a nice flush fit with fuse, mount and turbine.

this is what I did for my Roo....

1) using a tap drill size for your screws...drill the mounting holes thru the jetcat mount and into the Roo.

2) Counter sink the holes in the Roo so that your screws are about 1/16" below flush.

3) in a piece of scrap hardwood drill and counter sink a hole for the screw you are using. dill size = major diameter of the screw. now c'sink the hole in the block that the screw is 3/64" below flush.

4a) place a spare mounting screw thru the mounting hole in the jetcat mount and into the hole you just made in the block of wood.

4b) place an old screw driver in the mounting screw, with a small hammer stike the screw, to drive it flush to ID of mount.

what you have done is extruded the holes in the mount. the scrap block of wood is the die and the screw is the punch.

5) check the screw to be flush to the inside of the mount, you may have to strike them again, or deepen the C'sink into the "dieblock". once your adjustments are good then extrude the other 3 holes.

6) check fit of mount to the Roo, you may have to deepen the C'sink into the Roo.

7) install the mount. done

Thanks folks. This was all great info.
