Paul,For a stop gap can the 'block ' be transferred between trikes ?
all the best Paul
Probably, is the answer. But I am also seeing that the extremely limited range of the extremely clever internal clamp means there is a great deal of fine-tuning involved in order to get the darn thing to "lock" at a set length.
The draw-bar's pull exerted on the 4-way wedge affair seems to be less than 5mm and this means that the clamping force is rather limited. Too clever by half and currently ineffectual in its grip on the inside of the keel tube. I suspect that I shall have to slacken it all off and set the wedges initial position with the adjuster nut so that it is then VERY DIFFICULT to insert it into the outer tube. Then ram it home to the desired position and only then try and tighten it up. It may then "fix" to a length, and then I can pack the sides to prevent the "waggle". I am mindful that I cannot do anything that prevents dis-assembly, as it all has to come to bits for final powder-coating.
