I wanted to know if the Muhle R-89 razor has the standard 10/32 thread pitch, so I can swap the handle off another razor and put it on the Muhle. I think I read somewhere that some models of the Muhle don't have the standard thread pitch, so you have to stick with the handle that comes with the razor? But I'm not sure if I'm correct or not? For all the B&B members who own this razor, can you tell me if it has the standard threads like other 3 piece razors? Thanks.
Question about Muhle R-89 razor.

None of my tech handles will work on mine
It depends if you are talking about the Muhle with the Merkur head or not. The Merkur head is supposed to fit. I had the R89 old model. I think it was supposed to be the Merkur Head... The Muhle head fitted my Tech handle but the Muhle handle didn't fit the Tech head, go figure...

No, the one I ordered is the Muhle R-89 closed head, see link below for pics. I think it's a "Merkur style" head?

A lot of times the plated or (replated) head will have excess plating on the male threads.
They compensate by using a oversized tap (H7) on the female threads.
I've had problems with older Progresses not fitting my knobs until I got a oversized tap (H7)
The other way to fix this problem is to run a #10-32 thread chasing die down the male thread to clean off the excess plating.
I just had a client who bought one of my Bull Mastiff handles for his Goodfella, the handle wouldn't screw onto the head.
I had him send it to me and I had to run the die down the cap threads to clean off the excess black chrome.
Fit fine after that and took less time the it's taking to type this down.
If you buy a lot of old razors these simple tools come in handy for fixing buggered up threads.

How do you use a thread chaser? I Googled it, isn't what you're talking about one of these: http://en.wikipedia.org/wiki/File:ThreadingDies.jpg
Do you insert the threaded post in the center of one of these disks and turn it, or do you insert the post inside one of the many circles (3-4) per disk? I could probably buy the right thread chaser, but I need to know how to use the tool properly. Also do you lubricate the post with oil before using the tool or do you run the tool dry over the threaded post?

The head of my 23c fits ball-end handles. Haven't tried it the other way round as I'm so happy with my Muhle.
FYI, the head shown in this R89 picture is the new MP head. It is the same as the heads on the EJ razors now made with MP heads. The way you can tell is to look at the rounded (top) part of the head of each razor. The EJ and the R89 both have nubs on either side of the center thread that are flat on top. The older MPs have nubs that are rounded on top, much like the nubs on a Merkur razor. The reason I know this is that I own an EJ with an MP head and an MP with an older head. I hope this helps.
BTW, it is very hard for me to distinguish between both razors in terms of the quality and feel of the shave. Both are less aggressive than my Merkur 38c, but still give me a BBS shave after I do my ATG pass.
Just bought a custom stainless steel handle for Merkur heads from Pureslab. I was thinking it would fit my new 2009 Muhle head that came on my Edwin Jagger DE86. Will I have to run a die to make it fit?
I'm using this type of die with a 5/8ths wrench, a drop of oil on the threads first helps, it cuts the plating right off the threads down to the brass.
I took my new MP head down to the hardware store and found it to be a metric M5 thread. The 10/32 die will not work on this new MP head. Now remember, this is the new 2009 head and is different from the previous heads on the Muhle R-89 razor.

Was that the fine or coarse thread M5?
Because if I knew I could buy a tap and make a handle no problem, but of course it would only fit the Muhle head.
I did not know there where two different thread types for an M5. The best I can do is tell you I measured eight threads to a quarter inch.
All, I took the Muhle head from my 2009 EJ Chatsworth to work today and carefully measured the thread on a Nikon measuring scope.
I got a major diameter of 4.798
I measured the lead between 10 threads and averaged them came up with 0.795
So this would make it a M5-.8mm thread
Just FYI
The two posts are 4.79 diameter and are 25.44 apart
The holes in the deck are 4.910 diameter and are 25.43 apart.

I just received a beautiful 1951 Gillette Tech W2 with the black tapered Bakelite handle made in the good old USA. The handles swap perfectly between my new Edwin Jagger DE86 with its new 2009 MP head and this Tech. I tried each handle on each head and it appears they are the same thread size. Did Gillette ever use metric threads? How can this be? I tried a 10/32 nut when I was at the hardware store and it would not fit onto my MP head.
