Continuing with the baffles - the upper rear mount uses the engine crankcase bolts - more taking my finished engine apart! |
|
The LHS rear baffle has a strange alignment. The plane that the bolt location is in is well aft (1/2") of the part 15 brace mount. Not quite sure of the process, may need to put a bend in. Some trimming needed but pretty good out of the box. |
|
The RHS rear baffle on the other hand, needs significant trimming and working. The good news is the plane of alignment between the rear surface and the #15 brace seems much better. |
|
Lots of trimming by file, rotor burr and scotch brite wheel. Not difficult just taking it slowly and carefully to try and reduce any excessive trimming. |

Photo of the front looking back on the RHS rear baffle. |
|
The problem with the RHS rear baffle to RHS aft cylinder baffle (parts #7 & #8) is the gap. Not sure of the 'best' solution - looking at some of the other guys websites, cutting the flange off and using a piece of AL angle. More thought needed and probably no decisions until the engine is on the aircraft and a lower cowl is roughed in. |
|
Then onto the front baffles. The LHS uses the cylinder mount point (right of photo, half way up) which provides the top fixing of the angle stiffener. |
|
The stiffener is based from a .063 angle, the shaping was fairly easy, just requires time and effort. |
|
This is the underside of the LHS baffle. Note the part #13 (with the blue plastic on). I didn't understand the original layout - this will get a piece of angle at the top to support the lower surface of the baffle floor. |
|
The 'finished' support for the LHS baffle floor. In general so far the baffles haven't been too bad, just slow steady process. |
