Hi - i'm looking to build a manually operated hydraulic drawbar allied to a TTS style toolholder system. The toolholder side is sweet as is the hydraulic operation - basically i'm using a bike clutch slave cylinder coupled to a foot operated master cylinder. The problem i'm having is the Belleville washer stack - as from Hossmachine project MscDirect ? do the required washers for about $10 for a pack of ten but don't post outside continental America! Over in the UK I can find only one company who publishes prices - and sit down...........nearly $10 PER washer!
Surely they can't be that rare in the UK? I need 6 or 8No 1" OD, 0.5" ID and 0.065" thick with about 600 - 800lbs flat deflection loading. Can anyone help?
