sounds like you've a plan, keeping things flat and parallel is the both the objective and the trick. it'll give you arms like steel bars by the time you are done.
Still, I'd get the surface plate and indicator going sooner rather than latter, if you keep scraping with benefit of a reference you may well be making more work for yourself by taking too much of one area, not enough on another etc.
Keep in mind those pits or spots where someone's machined into the table might be 20thou or more deep - they make to difference to the accuracy of the table and may have you scraping until Christmas. |
