Reel Retainer Replacement

Another item for my old reel to reel tape recorders. A reel retainer replacement for vertical reel to reel tape recorders. The rubber retainers that came with these recorders in the 60's and 70's have mostly gone hard and do not work properly any longer.

I thought about designing this as a one piece, friction fit thing but realised sometimes longevity is best served by complexity!

Tap the holes on the Top to M3 and place a 17mm x 5.5mm or there about, spring in the slot in the lock piece (make sure the lock piece is the same way round as in the picture) and clamp the three bits together with 2 x 10mm x M3 countersunk machine screws and your done!
