Cross Slide Scraping Hercus 260
Had a visit from Mal of Australian Metalworking Hobbyist this morning.
We dismantled the Extended Cross Slide on my Hercus 260 Lathe to examine & get some dimensions.
Anyway while it was apart, checked it for flatness, it had 3 thou (.003") lengthwise convex on its base slide.
Spent the last 3 hours scraping it flat using the granite surface plate & blue.
Then scraped the cross slide saddle to match. This section was surprisingly flat & accurate, requiring little attention
The Extended Cross Slide had obviously moved over time, through stress relief.
All is now good !!!
Learnt a lot in the Scraping Course in Melb. (Thanks Phil) a couple of years back.
regards
Bruce

How straight is the dovetail now?
Gold, the colour of choice for the discerning person.

Practice is the best thing for mastering those skills Bruce.My cross slide is available as a tool to further hone your skills anytime.Always remember I am only offering to help you out.There is not much in it for me.
Well maybe a super refined cross slide with deadly accurate action but who's counting.Micheal.

Cross Slide Scraping
RC
Your question of accuracy, has been on my mind, so because its 40 degrees here today & too hot to do any work outside, took a few hours to finish the Hand Scraping job, on the Hercus Extended Cross Slide
The Saddle was accurate, so I scraped the dovetails on the Extended Cross Slide using the Saddle & its cross slide section as a master.
It took a while to scrape the dovetails, however all is now good !!
Better than new.
regards
Bruce
