Two weeks ago I got up the nerve to mill the X-axis table and saddle. Not being very patient, I assembled the table and saddle with the old gib. It slide smoothly from end to end with no wobble. I was very pleased with myself, but all was not well. Wear marks from the first slides showed that I had very little bearing surface. If I don't do something to smooth the ways, I will quickly be back to where I started. I have spent hours reading rancorous discussions on the net about the merits of lapping versus scraping.
Enough of boring you with background. I think I want to scrape the ways, and I think that I have a plan. Assuming that I can teach myself to scrape, this is it.
- Machine a cast iron dovetail master.
- Scrape in the master.
- Use the master to scrape in the bearing flats
- Use the master to scrape in the table dovetail ( or should it be the saddle first?).
- Scrape the saddle to the table.
