Thanks Simon for your advice.
I did have a 3mm tap from my aero-modelling days at Greenham Common (as was) but
blowed if I can find it.
Found some 2.5 mm brass screws on ebay but they don't fit very well.
Only a fiver but more money down the drain (grits teeth again).
Mixed some lightweight filler and crimson stain for the neck joint, reasonably happy with that.
Put it all to one side to concentrate on the finish.
Several coats of lacquer, leave for a few days then worked through the grits.
Got to 10000 grit today but only because I had some haha.
I can smell the solvent again slightly after sanding so I will leave it to cure
for a few days before the rubbing compound and polishing nonsense.
Then it will be tackle the hardware time.
I really like this guitar, the shape and feel in the hands is rather a joy.
Pics attached..the top colour is more like the close-up image, the full guitar image is rather orange
and not representative of the colour.
Once polished I will do some proper colour corrected images on a camera, not a bloody mobile phone haha.
