I would like to try my hand a hand scraping. I have purchased a scraper, bluing dye, and the typical references on the subject. I was planning on starting with two pairs of larger shop made parallels I purchased inexpensively on Ebay. I think they can be self referencing (4 surfaces per pair) using the rotating 3 surface technique.
However, if I wanted to progress to actual machine tool work I know I would need one or more reference straignt edges. The only thing I have found doing searches is Busch Precision products, and a price list from Newman Tools Inc. The 48" Scrapping Master (6848M) is listed for $10,175 (Ground Finish). The 48" camelback Dovetail Straight Edge (6648S) is listed for $6,222 (B Scraped).
This level of investment for hobby work is difficult to justify. Have I only found the Rolls-Royce of straigh edges, or is this what is required to do this type of work properly? I know there are probably used straight edges available (although I haven't seen them on ebay), but I would then have to spend the money to have them checked for accuracy, and resurfaced if required.
Are there other sources I should be looking at?
