EMF Paterson on sale

Now those Pietta grips look like they came from an Uberti revolver.      I've always preferred the look of Uberti grips.     Looking good Richard.

[ShotgunDave]

I have to concur with Mike. Those grips look much nicer. Well done.

[Captainkirk]

Much better look, Richard! Kudos to you.

Hi Guys, thanks for the kind comments. I took my living room display Paterson to do some work on it. After you do one gunsmithing job on a particular revolver, it's easy to repeat it. In less than 1/2 hour I had the arbor drilled and tapped for a arbor length set screw. I also checked if the 0.434 reamer for the barrel arbor hole would be helpful to this Paterson. The reamer fell right in. It seems that my newer (only 100 serial numbers higher) Paterson has a larger barrel arbor hole than the barrel arbor hole already reamed. So much for Pietta quality control.

I think that the fouling binding up of the Paterson is baked into the design of the Paterson. As Mike and scooby have previously said " the Paterson is what it is". Sometime one needs to live with design idiosyncrasies.

Regards,
Richard

I would be curious to know the various manufacture date codes on your Pietta Patersons. Pietta commenced using CNC machining ~2000, so anything older than that compared to a CNC gun is like comparing a Baldwin apple to a Granny Smith apple.

Jim, can't speak for Richard but pretty sure both were purchased new within the past 2 years.

Hi Jim, my first owned Pietta Paterson was purchased 1/2017. It has a date code of CN (2015). My second owned Pietta Paterson was purchased 8/2018. It has a date code of CS (2017). The serial numbers are only 100 apart. One can understand the lack of current production, minimal demand.

Hi, I measured the arbor and barrel arbor hole for my two Pietta Patersons:

CN (2015) arbor = 0.430". barrel arbor hole = 0.434", difference = 0.004"
CS (2017) arbor = 0.433". barrel arbor hole = 0.440", difference = 0.007"

Look at the barrel end of the Paterson and see that there is a reduced section next to the arbor hole to allow wedging the barrel off the arbor. This seems to show that fouling is inherent with the Paterson design.

Note, barrel on the left is an 1851 Pietta, the Paterson on the right.

Hi, Richard, does the single set screw function as both a barrel wedge adjustment and an arbor length adjustment?

[ssb73q]

Hi Kirk, the set screw just is used to adjust arbor length. A 10-32 screw would provide too small a surface area for a wedge adjustment. A small area would batter the wedge. Also, I don't drill the set screw hole all the way through the end of the arbor. If it was drilled all the way though it would weaken the part of the arbor that has to take the pressure load on firing.

Richard

Hi, I came across a write up on the Paterson where fouling is discussed:

https://www.guns.com/news/review/colt-paterson-reproduction-by-pietta-is-a-worthwhile-experience

He found two things that can be done to reduce fouling. One is to increase the barrel/cylinder gap to the width of a playing card, (~0.011").  I had already discovered that a large Paterson gap is helpful to reduce fouling. The other is to use a non stick cooking spray on the arbor. Maybe something like PAM? I'll try PAM the next time shooting the Paterson and report back.

Regards,
Richard

[Captainkirk]

No reason PAM shouldn't work.

[G Dog]

PAM works fine - for about 18 shots, then it's gone.

Three words:  White Lithium Grease. 

Put it on Sunday morning and shoot all week.

Hi G Dog, I already tried that, Lubriplate:

Hi, I was watching the Movie "Texas" from the novel by James A. Michener yesterday. What was really a hoot at the end of the movie was seeing a shootout by actor Ricky Schroder using two Patersons. I really liked that movie in that all the firearms are historically correct. If you like Patersons, don't miss the end of the movie Texas.

Regards,
Richard
