        With the price of a replacement Gib as above, it is hardly worth the effort and what is more you are starting with a full size unworn part.

          I am undecided at the moment whether to repair the old or replace it. If I repair the old one, it can go straight back in, if I get a replacement, I am led to believe from the Practical machinist web site, that I will need to scrape the new one in. At the moment I have made 2 temporary plates, one at each end of the gib, and I have the old gib held between 2 adjustable pinching screws, one each end. I have been using it today to edge the spectacle plates for my 6″ Garret, and everything seems OK, although I have not taken any big cuts likely to cause chatter, and finish is not an issue either. The gib itself seemed in good shape apart from the broken end, so I am leaning towards the repair, which seems less hassle than scraping a new one in. Thanks again for the input, and I would welcome comment on the scraping in issue.
          Chris Gunn.
