Amazon deliveries in the mainland UK are very quick, especially if delivered by Amazon themselves rather than by post or courier. Amazon Prime is normally next day if ordered before 5pm, though there is a growing tendency for two days as demands on them during lockdown have increased considerably. Non-Prime orders are normally 2-3 days. But most online ordering from UK web sites generally takes only 1 or 2 days to arrive.

I don’t think I’d have a problem with most guitar bodies on the current table, though maybe a long one like an Explorer or Explorer bass would be more difficult. The table at the rear is about twice as long as at the ‘front’. But the table is steel, so it would be possible to drill and tap holes in it to bolt on a larger wooden table. You’d just have to rout a hole and an indent for the various round plastic rings that allow dust to be sucked diwn through them.

The unit has mounting holes on its base so it can be bolted down for stability, but I didn’t have any issues doing the end of a guitar neck on it yesterday in a free-standing mode.
