Appreciate this question will have been answered many times indirectly - (I'm still reading threads).
I have acquired a selection of cast Iron Straight Edges (4 @ 6ft) 1 @ 5ft, 1 @ 4ft & 2@ c3ft - widths vary from 2" to 4" ( & a good 2ft in proven condition) I have a 18x24" granite in good condition.
The older SE working faces were all badly rusted up and whilst they show some signs of scraping approx 30- 40% of the faces are pitted and lost.
I have need of a 6ft SE to begin my Hollbrook lathe refurbishment.
My question is what would be the most efficient/ effective way to re-scrape the working faces of the SEs so that I can put them to good use ?
I had imagined working the 6ft units to each other to 'average them out', and then use these as reference for the shorter SEs - that however has now taken a knock having read the thread earlier this year about the Whitworth 3 plate method (Forrest Addy write up) - I should really read these threads more frequently !
I appreciate that I could use the 2ft good SE and overlap it (6") working my way along and maybe do the 3ft first to then repeat the exercise on a 4ft, then 5 ft and finally 6ft ? i suspect the possibility of error building up this would be a less sure method.
Any advise greatly received
