Well I'm back for another update, Unfortunately i didn't get quite as much as i was hoping done today but nether the less i have an update anyway.
Firstly here is the top panel marked for cutting out the window.
And after a short session on the scroll saw before filing we get this
And after a bit of filing we are left with this

But im not too sure on this i think it may be a bit small for this case and i also havent rounded off the corners so i think i will enlarge the hole and round off the corners aswell.
And mounted to the rest of the case
Now is the time to move on to the front and back panels so here you go front panel cut out
Front and back panels cut out
And then onto the back panel i/o cutout (sorry didnt get any pics of marking out etc etc
But here it is in the vice being filed
And unfortunately that's all for today more tomorrow.
Hope you enjoy
Josh
