Amp Project - Cab nearly done

Quite a bit of progress on the woodwork. I cut the front of the cab, having prviously done the sides, top and bottom. I cut the front slightly large and marked where it fitted to the main bodu. I put my little speaker baffl inside and marked where the speaker hole would be. I then marked out the two cutouts for the speaker and control panel.

To cut them I used a hole saw to cut the corners for the control panel and speaker - note the deliberate funky shape for the speaker!

I then used a jigsaw to finish the cutouts. Isn't it surprising how the quality of power tools can vary. I bought myself a jigsaw a few years ago. I don't want to name names, but it is a well known in the UK DIY brand. I never managed to cut anything even vaguely straight with it. My father in law bought me a cheap jigsaw for either burthday or chrismas and it knock spots off the "good" one.

I then glued and clamped everything up and left it a while. I then used a bearing guided trimming bit on the router to trim the front to size. That got me to the position of the first pic on here.

You may note from the date that chrismas is rapidly approaching. I also have two young boys so we need somewhere to conceal presents. The only space really is the garage which is where I have been working, so I needed to either get the messy work done, or pack up until after christmas. I chose to get a move on. 1/2inch round over bit into the router and everything looks nice and rounded. I have given the little baffle board and the inside of the cab a spray with matt black paint. As you can see I have a little overspray.

I tried the chassis in the cab for the first time. I have made the control panel cutout a tiny bit too wide and tall, but that may not be noticeable once the tolex is on. I was very pleased that the holes drilled for the chassis mounting screws are all in the right place.

There is not much to complete the cab bow - it needs a little filling and sanding. A couple of battens up the sides and maybe across the bottom at the back, and a couple of bits of ply to be a back. I may of course not bother with any form of back as all. I feel that may leave the valves and speaker a little vulnerable to damage though.

Then there is the tolex, grille cloth, handle and corners. I need to decide how to fasten the grille cloth to the baffle board, and how to glue the tolex to the cab. I am thinking copydex or evo-stick for thegrille, and evo-stick for the tolex. How on earth I am going to get the tolex round the corners is going to be the big question...
