Derek,
Just twigged your name on here! I posted your fork sliders (I'm mallardandcarpet on Ebay) on Saturday - and the minute I walked out of the Post Office - I thought 'I should have messaged you - to ask if you were going to the Haggis Gathering'. I picked up a couple of goodies there too - but not much!
Hope you get on okay with your Ariel Hub, some say they are not the most efficient brakes - but in good condition and well adujsted, they should do a decent job (nice wide shoe and drum). I have one on the back and it feels and works fine.
I have one for sale just now as I went with the 8" FW front. Watch what spoke pattern you get for that hub - I made the mistake of not realising the WM2 wheels came with a bunch of different patterns (1x1, 2x2, 3x1? etc). Ironically I just sold a brand new central wheels rim for half the price it cost me (ended up with quite a few spares by making this kind of mistake a few times)! By the way - don't think those sliders you bought will go with the Ariel hub/7" brake!
Anyhoo Let us know how you get on. Look forward to bumping into you at some random event north of the border. Why don't you stick something up telling us about your project - it's good to hear what others are doing and have planned.
Best regards Raymond.
