The new scraping thread

[Dave J]

I would ask around and see if you could get it ground first, it would save a lot of work and is not that expensive so I have heard.

I'd be asking Hercus or see if there are any machine rebuilders with a large bed grinder in Perth. That's the easy way out, then you can scrape the saddle to match. Otherwise, see RC's thread regarding his grinder refurb for survey tips. If you can wait a few months I can lend you some needed tools for that job.

You will notice the near extinction of the oil grooves on the rear bed ways. 60 years of lapping with grinding dust and oil has taken it's toll.


p.s. Thanks for the replies Fellas. I'd just slipped out to the shed armed with the Nikon. I wasn't expecting such a quick response.

Gregory,

It's the surveying that is a great concern. I will read up on Richard's Macson refurb. The little Hercus is very basic in comparison. I may need to lean on you for the tools.
If I can speak to Steve Durden at Hercus tomorrow, I will post the outcome.

Bob.

FWIW I have almost 2/3 of the parts that I need to make a Kingway alignment tool. I need to have made the cylidrical part, and some holders for the levels. With a this tool you can do some sophisticated survey.

Also, regarding the extinct oil grooves: I once saw a tool advertised on ebay as an oil groove router. I gather it did just what you'd expect, but the photos were not detailed enough to reverse engineer. On the other hand, digging a ditch in cast iron isn't too hard to do.

On edit number two: a Dremel tool in one of their router bases would do OK in restoring the oil grooves I reckon.

Any chance of a description of the tool and it's use or even an image?

Bob, do you have Connelly's book on rebuilding machines? I can lend you mine if not, however it's something I tend to refer to quite regularly so I think it's worth obtaining a copy if you intend going down this path. It's typical text book pricing, so no bargain. You may even be able to get Boffins to order it for you, I've bought a few machining/engineering texts from them.

If you study Connelly carefully I think the surveying conundrum will all make sense though I'll confess I've been scratching my head at times. There are many ways to skin a cat, but simply following his guide is arguably the best advice for those like us who only get to do a handful of machines in our lifetime.

+1 for Connelley. There may be a PDF floating around.

here's some of what I have on the Kingway tool. There were a couple of threads on PM too.

[Dave J]

Here you go Bob, easy made by a bloke like you.

Forgot to mention, I think it was RC posted a thread over on PM which is where I got the pictures from.
If you do a search there is a bit more info on this tool.

Is your intention to make this like new or useable?
For the oil grooves a Rotary Bur in a die grinder or electric drill,by lookingat some of them it appears they were done manually,stone the burs left.
If the main use is for Mill tooling I would take readings along the bed and use the part that has the least amount of wear or taper.
If on the other hand you were sharpening reamers or longer bodied items it would be more of a concern.
As most sharpening would normally occur in the longitudinal plane the cross slide would not be a great worry.

Here's some photos from a thread on PM. The pictures are from Shapeaholic in Sudbury, Ont.

Eskimo has the Connelley book on CD. If you do a search for it on Google it is usually available for free down load.
