Mikey, I have no idea how old the 2100 was when I took it from Clive to work on it; but it had certainly had a busy life.
It wasn't visibly abused, but ......
1 the cutter block bearings were worn - so I replaced them
2 the cutter block was stripped, cleaned, adjusted and rebuilt - several pressure washers were replaced
3 I turned two knurled, threaded knobs for the measuring arms, which were missing.
4 there was no bottom or top stop. So I sourced the two stops, but they were both incomplete so I had to make knurled, threaded adjustment stops and lock-rings for them.
5 the top stop measuring rail was also missing so I made a new measuring rail and milled it out, to take a small rule which was very similar to the original fixed rule for the bottom stop.
6 I made a new mat plate, and a locator pin for the beveled margin fence.
7 cleaned and trued the clamp rail which was slightly twisted.
That was it: the reason I bought the incomplete top & bottom stops was because I sourced them from Mark at Underpinner Spares for £70 incl. P&P, which was less than half what they would have cost anywhere else. And Mark got them to me without any delay.
I can't envisage Keencut or Valiani producing a 'clip-on' system that is not sufficiently robust - just when I see things like that, I wonder
