Well I have spent an hour tinkering this afternoon and it has highlighted several problems

I can't do anything until the 'chocolate' gibs have been replaced, last weekends work by Bogs has highlighted how utterly useless they are. So i thought i would make a quickie replacement out of some scrap, but i couldn't find anything of a suitable size and with the knackered gibs no method of machining what I have

so i will have to get something suitable tomorrow, I then realised that even with the added movement on the cross slide I still couldn't machine tapered gibs

all very frustrating
