Default Converting 32 HE to a snub

I have a 32 HE sn 103673 that I bought to steal some parts off of for my 32 Target. After that, I put the HE back together with some left over parts and all works as it should. The finish on the barrel has some minor issues, so got the idea to convert it to a snub.

I bought a 2" barrel that looks to be off of a model 30, and an extractor star and extractor rod for the 2". The HE has a right hand threaded extractor rod and the replacement is left handed.

In disassembling the extractor and extractor rod I noticed that the old rod has a flange on it and the new one does not. I know I will have to shorten the center pin, but will the newer extractor parts work with the old cylinder?

It's not that I need to do this, I could just sell the piece, but I thought it might be fun to put this together.

Thanks in advance.

Robert,

Sounds like a fun project. Your .32 #103673 is a .32 Hand Ejector Model of 1903-5th Change made from 1910 to 1917. And The extractor parts were not changed until the end of WWII when the RH thread was changed to LH. So parts can be readily found.

This is a simple project but there's a lot of little details to consider:

1. I frame extractor rods didn't change to LH thread until soon after the WWII ~ 1948-49 (whenever pre war RH threaded parts inventory was exhausted.)
So RH Ext rods are numerous.

2. If you want to use the LH Rod replacement you already have, you'll have to change the star extractor. You'll run into little issues like the LH star needing fitting to your cyl. Also matching alignment pins in cyl with holes in the star. So simpler to start with RH ext rod parts.

3. The 'flange on the rod is called a collar. It's sometimes integral to the rod but most times it's a separate piece. So it's simpler to use a rod of similar vintage to your gun to get the same collar style and location as your gun. In that case, all you'd have to do is cut the front ends ctr pin and rod to proper length for the snubby barrel, and re-knurl the tip of the new rod.

4. Also to use the later vintage LH rod, you'll have to match the collar placement of the new rod to your old rod for the large diameter spring to work properly and not bind. You may have to trim the rear threaded end of rod and threaded front end of star shaft to locate the collar to match the original rod/collar location. Then cut the front end of the ctr pin and rod and for proper overall length. And re-knurl the tip.

5. As you can see, it's much easier to start with a matching vintage rod with RH thread. So just get another rod that matches yours or cut down your original rod, but you likely want to keep the original to convert back to longer barrel if you ever want to.

I hope this helps, any questions just ask,

Hey, Robert...this would be a great project to document with pictures!! I love these sorts of projects, and it is fascinating to follow them. Hondo is a great mentor, as well. I'll be following this thread!!

Good luck!!

Best Regards, Les

Unless the extractor rod has a large barrel or mushroom knob on the end the simple solution is to use the orginal rod and center pin, just shorten close to correct length , then use a fine file to get just right. Then take the rod to a machinist and have him chuck it up in a small lathe and reknurl the tip. I have done it on 4" to 2 1/2" conversion and even fixed up the end of a rod some idjit had smeared up with pliers or something. If I wanted to shorten a rod with a mushroom end and keep the mushroom I would cut off the mushroom shorten the rod, drill the mushrom to fit the rod, then silver solder it on.

Based on Hondo's advice I bought a spare rod and center pin so i can modify them and still have the original. Plus it gives me two chances to get it right. I can use a small lathe at the plant i run, and since i spent years running a lathe, i plan to try this all on my own. The extractor rod has the large knob, and i thought to turn it down and knurl it rather than mill a flat on the barrel for clearance. The silver solder idea will be easier than rethreading the rod.

Question, is the barrel pin straight and can it be pushed out from either side?

I will post pictures along the way, but be patient with me....i tend to procrastinate.

Robert
