think I put them up on CEF a long time ago - can't look for them - CEF's down again this evening

- fine this morning

.... interesting idea, but as Ruben says, the geometry is all to cock to be really effective
interestingly .... the guy in the video is using one of those converted plastic 'squeezy' clamp thingys for the FF couplings at 1:47 ... obviously no pressure in them ... went together waaaay too easily

..... must have a go at knocking one of those out
