EVEN I USE MECCANO :-) SOMETIMES!
AN ALL MECCANO MINI GEARED ROLLER BEARING???
OH YES, IT IS!
Just to prove it - the illustration shows a drawing of the geared roller bearing also featured on ‘Aggravator’, my micro Hammerhead Crane.
"ALL HOLEY" :-) although the 1.5" Pulley centre was ‘treated’.
The bearing has 14 No 38A Plastic spacers A as ‘floating‘ rollers, centralised with a 1.5" plastic pulley B with the centre bored out to 0.375" Dia mounted in a 137 wheel flange C on a plastic 27c 95T gear D with its boss upwards fixed to the top plate of the gantry E and plinth F by two upward mounting bolts and nuts G.
The top bearing plate H rotates freely
and this is the 109 mounted with the boss upwards forming part of the base
of the jib which is pivoted on a vertical slewing shaft omitted for clarity.
Happy Mutilations !
