Got a Lathe Spider

A couple weeks ago I ordered a spider for my 7x14 minilathe, something I should have bought years ago. Little Machine Shop had it as their weekly special so I finally pulled the trigger on it.

Link to minilathe spider: https://littlemachineshop.com/products/product_view.php?ProductID=1136

The spider threads onto the end of the spindle and provides additional support to long workpieces, to prevent them from whipping around.




To install the spider you remove the gear cover on the end of the headstock and simply thread it onto the end of the spindle.




I used it today while drilling and tapping the flared end of the factory ramrod that came with my Investarm Gemmer Hawken. Even though I bought an unbreakable Delrin rod for it from Track of the Wolf, which is threaded on both ends, I want to keep the OEM wood rod as a spare.

This shows the ramrod mounted through the spindle bore.




And here I was using the lathe as a tapping guide to keep the 10-32 tap straight. I did not do this under power. Instead, I used the chuck key as a handle and rotated the chuck manually. Power to the lathe was off when I did this.




Aside from drilling and tapping the end of the OEM ramrod to accept 10-32 accessories like cleaning jags, worms, and bullet pullers, both ends of both rods got drilled and cross-pinned. To drill the holes I used my minimill.

Always cross-pin your ramrod tips! Failing to do so can result in the ends pulling off the rod if you get a jag stuck or need to pull a ball. It's simple to do so:

  1. Drill a hole through the rod crossways. I used a #40 drill because for my pin I used some brass rod 0.098" in diameter.
  2. Chamfer both ends of the hole.
  3. Drive the rod through the hole and cut it off. I used side cutters.
  4. Using a hammer, peen over both ends on a metal surface. I used the anvil on my bench vise.
  5. File the ends of the pin smooth.
One end of the Delrin rod from Track is tapped 10-32 and the other is 8-32. I will use 10-32 jags, etc. and have an aluminum T-handle with an 8-32 stud on the end. I have qualms about using it for cleaning or ball pulling.

Just another example of how my small, tabletop machines help me out with gunsmithing tasks.

Investarm Gemmer Hawken Rifle

With Lyman getting out of the black powder business, Muzzle-loaders.com has taken over as an importer of Investarm guns. I had a 10% off coupon from them that expired at the end of last year, so on 12/26/23  I put it towards a left handed .54 flintlock Gemmer Hawken. It arrived this past Wednesday. The Gemmer Hawken is the current incarnation of the Lyman Great Plains Rifle, which for decades has been very highly regarded for a production muzzleloader.

Back in the 1990s I had a LH flint .54 Lyman GPR but sold it off after a few years. At the time I wasn't hunting and my shooting interests were more along the lines of milsurps and S&W revolvers. I wish that I had kept it. Let's just say that the Investarm rifles made today are not as nice as those made even 10 years ago, much less my old GPR. In particular, the triggers were horrendous. Rough, difficult to set, and so heavy when unset as to be unusable. So, I ordered a Davis Deerslayer from the Log Cabin Shop and it arrived today. The Deerslayer was originally designed for use in  the T/C Hawken and Renegade, rifles but it also works in similar guns like the GPR/GH.

Installation was painless and while the instructions mention removing wood, that wasn't required. (Doing so may be required on a T/C.) The rifle now has an easy to set trigger that would be usable even when unset. Dry firing it feels like I'm holding one of my custom muzzleloaders. In my opinion the Davis triggers are worth the $80 asking price (although it shouldn't be necessary to replace the triggers on a factory rifle to get something usable).

Pic before installing the new triggers:




Yesterday I added a couple coats of clear Watco Danish Oil to the stock, which is some unspecified European hardwood that was lightly finished. Older Investarm guns, including the Cabela's Hawken I took a big doe with in 2022, had walnut stocks. I also replaced the vent liner with an RMC unit that uses an Allen wrench for removal. It's coned internally as well on the outside so it should help ignition.

The lock sparks well even with the cut agate flint that it came with. L&R now makes left handed RPL replacement flintlocks to fit the GPR/GH but I'll give the factory lock a solid workout before thinking of replacing it.

The only other modification I have planned it to put slots in the barrel keys and install pins held in by the escutcheons so they can't fall out and get lost.

I may not be able to shoot it until next weekend, due to the weather. I'm hopeful that it will shoot well with 70 - 80 grains of 3Fg and a patched .530 ball. I'm also going to try some .526 balls which should make for easier loading in the field. My reason for getting a .54 is to improve my chances of a complete pass-through on the large whitetail deer up in Tioga County, compared with the .50s I've been using.

As an aside along those lines, I'm hoping to work up a good conical load for my percussion Cabela's Hawken .50 that I can use during the early antlerless season. I have some Hornady Great Plains bullets that should shoot well in the gun and be really effective on deer.

Aside from the larger ball, the Gemmer Hawken will give me a flintlock rifle that's easier to handle inside a deer blind, since it's significantly shorter than the longrifle I toted last week.

More to follow after I shoot it ...

Galco Draw-Ez for Holsters

Recently I've posted about M3 Tanker Holsters, of which I have three variants. The no-name copy that I wanted to use with my Beretta M9 was very snug, so I did a couple things to make it usable.

First, the leather was very dry, so I worked in some 100% neatsfoot oil. This softened it a bit and will preserve the leather. At some point I'll also rub some Sno-Seal dressing into the outside, to provide some water repellency.

After treating it with neatsfoot oil, I wrapped the Berretta in Saran wrap and forced it into the holster for about a week. This loosened it a little and the I added a plastic bag over the Saran wrap, then let it sit in the holster for another week or so. By this point it was getting there. However, the gun still dragged when drawing it.

So, the final step was to rub some Galco Draw-Ez Solution into the inside of the holster where the gun rubbed against it. I let it sit for about 10 minutes, put the naked gun back in, and tried drawing. It made a noticeable improvement.

Draw-Ez comes in 1/2 oz. (15ml) bottle. It's not cheap but a little goes a long way. If you have a leather holster that is hard to draw from it's worth trying.

Jewish Boycott?

JEWISH BOYCOTT

BY John Neville Cohen – Publisher


BY COMUNIDAD JUD√ćA · 13 SHEVAT 5781– 26 JANUARY, 2021


A short time ago, Iran’s Supreme Leader Grand Ayatollah Ali Khamenei urged the Muslim World to boycott anything and everything that originates with the Jewish people.


In response, Meyer M. Treinkman, a pharmacist, out of the kindness of his heart, offered to assist them in their boycott as follows:


“Any Muslim who has Syphilis must not be cured by Salvarsan discovered by a Jew, Dr. Ehrlich. He should not even try to find out whether he has Syphilis, because the Wasserman Test is the discovery of a Jew. 

If a Muslim suspects that he has Gonorrhea, he must not seek diagnosis, because he will be using the method of a Jew named Neissner.


“A Muslim who has heart disease must not use Digitalis, a discovery by a Jew, Ludwig Traube.


Should he suffer with a toothache, he must not use Novocaine, a discovery of the Jews, Widal and Weil.


If a Muslim has Diabetes, he must not use Insulin, the result of research by Minkowsky, a Jew. 


If one has a headache, he must shun Pyramidon and Antypyrin, due to the Jews, Spiro and Ellege.


Muslims with convulsions must put up with them because it was a Jew, Oscar Leibreich, who proposed the use of Chloral Hydrate.


Arabs must do likewise with their psychic ailments because Freud, father of psychoanalysis, was a Jew.


Should a Muslim child get Diphtheria, he must refrain from the Schick” reaction which was invented by the Jew, Bella Schick.


“Muslims should be ready to die in great numbers and must not permit treatment of ear and brain damage, work of Jewish Nobel Prize winner, Robert Baram.


They should continue to die or remain crippled by Infantile Paralysis because the discoverer of the anti-polio vaccine is a Jew, Jonas Salk.


“Muslims must refuse to use Streptomycin and continue to die of Tuberculosis because a Jew, Zalman Waxman, invented the wonder drug against this killing disease.


Muslim doctors must discard all discoveries and improvements by dermatologist Judas Sehn Benedict, or the lung specialist, Frawnkel, and of many other world renowned Jewish scientists and medical experts.


“In short, good and loyal Muslims properly and fittingly should remain afflicted with Syphilis, Gonorrhea, Heart Disease, Headaches,Typhus, Diabetes, Mental Disorders, Polio, Convulsions and Tuberculosis and be proud to obey the Islamic boycott.”


Oh, and by the way, don’t call for a doctor on your cell phone because the cell phone was invented in Israel by a Jewish engineer.


Meanwhile I ask, what medical contributions to the world have the Muslims made?”


The Global Islamic population is approximately 1,200,000,000; that is ONE BILLION TWO HUNDRED MILLION or 20% of the world’s population.


They have received the following Nobel Prizes:

The Jews are NOT promoting brainwashing children in military training camps, teaching them how to blow themselves up and cause maximum deaths of Jews and other non-Muslims.


The Jews don’t hijack planes, nor kill athletes at the Olympics, or blow themselves up in German restaurants.


There is NOT one single Jew who has destroyed a church.


There is NOT a single Jew who protests by killing people. The Jews don’t traffic slaves, nor have leaders calling for Jihad and death to all the Infidels.


Perhaps the world’s Muslims should consider investing more in standard education and less in blaming the Jews for all their problems.


Muslims must ask ‘what can they do for humankind’ before they demand that humankind respects them.


Regardless of your feelings about the crisis between Israel and the Palestinians and Arab neighbors, even if you believe there is more culpability on Israel ‘s part, the following two sentences really say it all:


‘If the Arabs put down their weapons today, there would be no more violence. If the Jews put down their weapons today, there would be no more Israel.”


Benjamin Netanyahu: General Eisenhower warned us. It is a matter of history that when the Supreme Commander of the Allied Forces, General Dwight Eisenhower, found the victims of the death camps he ordered all possible photographs to be taken, and for the German people from surrounding villages to be ushered through the camps and even made to bury the dead.


He did this because he said in words to this effect: ‘Get it all on record now – get the films – get the witnesses – because somewhere down the road of history some bastard will get up and say that this never happened’


Recently, the UK debated whether to remove The Holocaust from its school curriculum because it ‘offends’ the Muslim population which claims it never occurred.


It is not removed as yet. However, this is a frightening portent of the fear that is gripping the world and how easily each country is giving into it.


It is now more than 65 years after the Second World War in Europe ended

Now, more than ever, with Iran, among others, claiming the Holocaust to be ‘a myth,’ it is imperative to make sure the world never forgets.

Guns for Jews

I've put together a primer on gun ownership for fellow Jewish-Americans who are new to it, in the wake of the October 7th pogrom. It's in the form on an article I'm hosting on my Google Drive.

Guns for Jews.

Please share it to anyone who you think might find it useful.

The M3 "Tanker" Shoulder Holster

Sometime around 1939 - 1940, the US Army adopted a shoulder holster as an option for carrying the M1911A1 pistol. A similar version was adopted during WW2 for the S&W Victory Model and Colt Commando revolvers. These holsters remained in service at least until the 1990s, AFAIK. After the 1911 was replaced with the Beretta M9, it was used for the new pistol.

Several years ago I picked up a copy of the USGI M3 shoulder holster for the S&W Victory Model from the now-defunct Pacific Canvas and Leather. I like it a lot for carrying my Model 15 or Ruger Police Service Six, but of course it's too small for an N-Frame.

I recently replaced the grips on my S&W Model 28-2 Highway Patrolman, which made the gun much easier to shoot with my small hands. It previously wore a set of Herrett's Shooting Stars. I replaced them with a set of Thai Magnas + a BK Grips adapter. With it now fitting me better I started thinking about packing it as a woods gun.

So back on 9/3 I placed and order with El Paso Saddlery for one of their “1942 Tanker” holster, which is their version of the USGI M3 shoulder holster. It arrived 9/15, much sooner than expected based on what the EPS website says.




If it looks backwards it's because I'm a southpaw.

It’s very nicely made with nice leather, stitching, and hardware. They also threw in a key fob.

Out of curiosity I put my Colt Shooting Master in it and except for the fact that it’s too short for a 6” barrel, the holster fits the gun well. So, if I ever pick up a 4” Colt New Service this holster is usable with it.

A S&W Heavy Duty would look right in this rig.

I'm looking forward to using it in the woods.

I also have a copy of the M3 for 1911s. I don't have a 1911 anymore but I do have an M9, so tonight I tried it in the holster.



(I don't recall where I got this one from. Maybe Amazon. I'm pretty sure it was made in India.)

It's very snug and takes quite a bit of force to insert. So, since the leather was dry I gave it a good coat of neatsfoot oil and plan to leave the Beretta in it for several days in the hopes it'll stretch out.

As-is, my Browning High Power and Beretta 81 Cheetah fit OK. The CZ P-09 won't fit at all.

I've recently run across variants of the Tanker holster cut like the leather ones but made from canvas. The Amazon link above has some. I've never tried them and they are a bit less expensive, but I've no experience with them. They might work well, might not.

I also ran across this blog post extolling the merits of the M7 shoulder holster. The M7 differs from the M3 in that it includes a chest strap to help keep it from flopping around. That post also lists a variety of pistols that will fit, which makes it close to being a universal holster.

As to why to use one, as noted above I find it comfortable. It also makes the gun available if you're sitting in a vehicle. The strap can be adjusted so you can wear it over your clothes or concealed under a coat. Also, if you can't normally carry a gun but want one that you can quickly throw on, it's an option.
