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.
