The LRM hornblocks have a circular extension, over which fits an etched bracket – a photo is worth a thousand words, so I include a shot of the instructions and fret, below. I have toyed with the idea of soldering a pivot directly to the top of the hornblock. In hindsight, it would have been far easier to leave the powered axle in a plain bearing, but I hadn’t anticipated the lack of clearance, and had fancied a stab at using CSB suspension. This is very much a learning exercise for me.
An alternative to the LRM tags are the ones from High Level. Chris has designed some very clever tags that fit over his axleboxes and allow the choice of three heights. This gives you flexibility over the height of the CSB wire over (or under) the axle centres, or within the frame profile.
