Help Restoring Deckel FP1

[Ogriobhtha]

This is a bronze plain bearing then I suppose How good is the bearing itself How smooth is the journal

What is the best way to assess the soundness of the journal praytell?

Just to be clear, that is not an FP1 spindle assembly.
Concept is the same, details may be quite different.

Spindle OD can be assessed using “V” blocks and a known flat surface (surface plate or machine table).
And a good tenth’s reading indicator with surface gauge or height gauge.
Testing the contact of a good spindle to the bushing is done less thrust washer using Prussian blue.

All that Ross says But I would look at the surface first
It has to be very smooth No signs of any scratches or scoring Idealy scraping marks inside the bronze bushing
The journal was lapped when new

For the professionals only. Back then when the FP1 was introduced MT was universal for a toolroom machine which doesn't need rapid tool changes. MT4 tooling is available at reasonable prices and for a beginner hobbyst it would be just fine.



Maybe you can find one in EU and have it shipped to a reputable member here for inspection and re-shipping.

So pardon my ignorance, but is there any distinction between MK4 and MT4?

MT is Morse taper in English
MK is Morse Konus in German And to be complete MC is Morse conus in Dutch
Phisicly all the same

Ok that’s sort of what I suspected. Thank you!

Oh btw CM in Frenche Cone morse

MT is Morse taper in English
MK is Morse Konus in German

I always thought it was Morse Kegel in German

 

[Peter from Holland]

I always thought it was Morse Kegel in German

I stand corrected

 

[ballen]

I stand corrected

I'm not confident that I'm correct. I got this because I am sure that SK40 means Steilkegel 40. Steil = steep and Kegel = taper

PS: I think either one is OK: https://de.wikipedia.org/wiki/Morsekegel gives both Morsekegel and Morsekonus.

The standard DIN 228 defines following terms for the same morse taper (metric taper is not meant in this case):

English title: Morse tapers and metric tapers; taper shanks
German title: Morsekegel und Metrische Kegel; Kegelschäfte

"Morsekonus" seems to be an old-fashioned word, but the germans who know what Morsekegel means will also understand Morsekonus.
