Fascia capping problem

Hi,

I have currently got wood facia board grooved with a ply soffit in. I did my downstairs garage to learn all the requirements to cap/add soffit trim etc and that went ok, I just screwed the soffit on the lip of existing fascia and threw the capping over to support it.

I'm doing the roof now and the Original windows were replaced a while back and they literally have zero gap available to put the fascia capping over the existing fascia wood board.

Key challenge is I've ordered all the fascia capping board, before you say anything, I tested with a small bit of facia it on another upstairs window but that one for some reason was just about fine to get the fascia on the existing lip.

I don't want to get this existing plywood soffit out, it's laid along the brick line and im seeing this as causing more aggro with the brickwork.

There is a 20MM between existing soffit line and the bottom of fascia, when the new Soffit is on that is 9MM, that leaves 10/11MM.

Fascia is 9mm thick, leaving 2MM.

Has anyone had a similar issue?

1. Cut just enough fascia board off the existing lip all the way along the 10M front/back with a jigsaw?
2. Use router to do the same?

Or is this whole plan doomed OR am I overthinking it.

I've done a window section to test and this works with a jigsaw.

I'm going to need to run a guide (Old bit of facia cut off thats straight enough screwed on temporarily) to get the Jigsaw running straight.

I'm assuming I won't need to treat the cut end of the fascia wood if being covered up???

Jigsaw will be pants and will wander about like a fiddlers elbow. We use a (battery) circular saw. You need to leave enough meat on the bottom of the existing fascia so that the existing soffit board does not fall out.

Thanks for the tips.

I agree, at height on the ladder for the test section it did wander, I am going to use a guide screwed in.

Doing it on the ladder wasn't ideal so I'm hoping when my tower arrives Thursday it will be easier to manage the jig, plus the Makita Jig I've bought for this job is pretty nice to work with tbh.

I've got a mate who can help loan me a Circ on batteries though so thanks!
 
Ok, so job was done in about 3 days on/off over the bank holiday.

Used an old line of fascia cut off to provide a jigsaw run of the fascia, i've saved 5M worth for the front of the house as taking it off every metre or so at a time got rather time consuming.

Pain in the ars regardless cutting off 10mm of wood for 8 metres two storeys up.
 
Thankfully I wear specs, although they've needed to be replaced after getting knocked off when bending through the tower I hired lol.
