Title: Angle plate repair
Post by: steamer on July 27, 2012, 09:32:13 PM

Hi All,

I bought this from a UK based tooling house as it was just the ticket for some work I want to do on my Wallaby


It was advertised as precision ground....as you know I've been wielding a scraper as of late so I decided to see just how precise it was

As received

So I did a mark up on my surface plate and got this.....

YUCK!......OK got the carbide blade out and started in on it.
After a couple of cycles...

Notice the low area on the left side...it's still there... but the bearing is improving
20 or so cycles after that....and I was leaning on the scraper

At which point I called it good....I took about .005 off!   

I checked squareness now and found it was pretty good!....but I have to chaulk that up to luck!

I took the issue up with the vendor, and he sent me another one...free of charge......so I'll check it out...and probably offer it for sale...don't really need 2

Hi Dave,
This looks like another case of machining un-seasoned castings far too soon after being cast. Perhaps this could also be a case of "just in time" production not paying of, well, as far as the customer is concerned.
Nice save, though.
Ned

Not a bad theory Ned......Let's hope it stay's put!
