[sdiy] Designing control surface, potentiometer heights?

[Tom Bugs]

Yep -- Lorlin type rotaries are too f'ing tall for me -- there are quite 
nice Alpha ones for not too much $$$ available through Mouser (I now use 
Song-Huei equivs which are even more affordable but MOQ is 1000 
pieces..) - only shame being that you can't change the number of stops 
like on the Lorlin type
Alpha SR1712F is, I think, what I meant (search via Mouser) - but hmm 
they're not so cheap... and I'm sure they had them with spline-shafts...

A problem I've found is the body of the pot/switch before the shaft/actuator can vary greatly in height. So my rotary switches (Lorlin type) are 20mm or so high in the body, whereas the pots and sliders are only around 7mm. See the link for an illustration in CAD: -  https://flic.kr/p/qhipLE
