Decided to have my Milling machine slideways Re-ground. It's difficult to make accurate helicopter parts with worn slideways.
I used Unislide Grinding in the UK, it cost £1440 for the table, Saddle and Knee ways to be done but not the post as I didn't think it was necessary on my machine
They welded the holes in the table and ground all sides of it so it looks very nice, the Gib's have a layer of something added to compensate for the material removed.
I was very reluctant to take my milling machine apart to have this done because it's such a useful tool but very glad I did.
As it was apart I cleared all the lube holes of grease (someone had used grease instead of way oil) and I'm going to modify a grease gun to inject way oil through the grease nipple type fittings. Looking forward to making some more rotor parts and seeing how much better it is!

I have a Deckel FP2 - they are also often full of grease instead of oil that creeps down.
No one does RTFM, before they grab the ol' grease gun.

I've not used a Deckel Fp2, are they good machines? Yes it's a shame some people don't read the manual, as I'm sure your aware grease attracts grit and swarf and turns it into a lapping paste perfect for advanced wear. The manufacturers could have used a fitting other than the one everybody associates with grease.
