On the current project, I've just this afternoon trialled and fitted a pair Andrew Crawford's 'smartHinges'. I hate with a passion fitting any sort of brassware and on this particular jewellery box I was terrified that the lid and base edges on the large routed 'ole for the Birds Eye Maple 'moon' might have a 'step' and require some 'adjustment'
The set-up instructions on Andrew's site are very explicit and easy to follow so I spent an hour or two this morning getting the router table prepared. I then did a few trials on a small oddment of oak:
Girding lions I then proceeded to route the four slots in the Indian Rosewood box, drilled the pilot holes (Andrew recommends a set of drills in 0.1mm increments) and inserted four screws, having first lubricated them with a smear of Vaseline. No steel screw is provided to cut the threads but fortunately I had a box of No.3's that were ideal; there are however, plenty of brass screws in the packet.
Having screwed the lid to the box...
...I then closed it to check that everything, inc. the aforementioned 'ole was in line. Which it was, absolutely spot on
These things are expensive, but no more so than the Brusso hinges from CHT. Provided you follow the instructions to the letter you should obtain a respectable result. No affiliation to 'smartHinge' in any way - Rob
