Picked up some cheapo varnish from B&Q – they’re selling Sadolin varnish (in certain colours) at half price – so the shed is now “light oak” rather than the clear I was going for, but I saved myself £20 so that’s got to be a good thing. One thing I’m finding is it’s a real pain cutting accurately through the plywood/kingspan sandwich – I bought a reciprocating saw (one of those “alligator” jobs) – but the blade bends so it’s impossible to cut straight and guarantee where the blade’s going to pop out the other side. I’d noticed this issue when cutting the rooflight (where I was holding the saw vertically) – so I didn’t even try when cutting the window. So I had to resort to measuring the hole on the inside and trying to match it up on the outside – measured it FOUR times and it still wasn’t bang on… Came across one of those lovely moments where I had to bodge and the bodge was better than the original idea (always nice)…
I’d measured the double glazed unit and accounted for the width of the frame (then checked, and double checked), cut the holes in the walls, painstakingly spirit-levelling and adjusting as I went… Fitted the frame and of course, the window didn’t fit – by almost a whole half inch all round – How does that happen?
I’d mitred all the frame up, so I couldn’t redo it so I dug out the power planer and cut a 5mm rebate 2½ inches into the frame all round. Once I married the window up it fit so snugly it’s like I’d designed it that way… I love it when a plan comes together!
