My kids keeo giving me these at birthdays and xmas – I think they’re testing for when I lose the capability to follow sequenced instructions – so I’ve built a few of ’em.

They require close attention and sometimes there’s a risk of breaking parts as you press them out, so all-purpose superglue’s handy.

They’re good fun and generally work well.

I’ve done a few of these, a couple of marble ones and a surprising accurate timer/clock thing.

Being wood, I usually end up having to repair…..

I broke a part or two popping them out of the matrix on the first model I built. Nominally they just push out under thumb pressure but some parts are a little fragile because of their shape/size.

Once I realised that and took the time to consider each part and take appropriate action (Exacto knife in some cases; extra support etc), it wasn’t a problem going forward. Above all don’t try to hurry.

This is reason for many of my failures!

I get near the end of a project and get carried away with the finish in sight!
