How to Make Springs

How to Make Springs: "SPRING DESIGN
If you're trying to make a spring to replace a broken one, you don't need to know a whole lot about design. On the other hand, if you're making a prototype of a machine, for instance, and you don't know exactly what you want, then this page is for you. Here you'll learn some basic data about spring design, which is what you'll need to know to make exactly the spring you want."

Here's a link to a whole list of ballistic programs.

http://www.stevespages.com/page8b.htm


"Don't mention it. Of the many programs listed in the link, two that I like to use for determining the mean radius are Group Size Calculator and RSI Shooting Lab.

Group Size Calculator is very inexpensive ($10.50) but does require a scanner to input your targets. RSI Shooting Lab is much more expensive ($99.95) but does not require a scanner. Both programs require careful calibration of the program to your scanner/monitor to provide accurate results.

There are other programs that don't require calibration, but you have to measure the coordinates of the shots on your target and enter the numeric values into the program by hand. (More time consuming.)"

Trying to see if a burglar that is breaking into your home is armed or unarmed wastes valuable time and really doesn't matter. A high percentage of assaults and killing of victims is "by items readily available". Personally I would try to retreat to the room my wife or others were in. But if I ever did have to use a firearm in self defense, I would keep shooting until the fight was over. Most drug addicts are not stopped with 1 bullet, they'll keep coming at you!

What you do next is VERY important!

1. Secure you house and family. I don't care what those clowns on TV tell you, protect family and self FIRST.

2. Call your lawyer. If it is nights or week-ends leave a message.

3. Put you gun on the dresser. Make sure it is in full view from the doorway and within easy reach.

4. Call 9-1-1 LAST. "Some one is shot at 1234 street and may need assistance" Answer nothing but name and address. Admit nothing. "My lawyer is Joe at 555........"

Go get a pencil and write this down.

My name is _________ of _______ street
I defended myself and family with minimal force

You have a good chance of getting an honest policeman to show up. There is a possibility that one of them is related to your dead intruder or they don't like people with guns or even blue cars in your driveway. You will want your firearm on top of a dresses or table so they won't have an invitation to rummage around your stuff. This statement you wrote down is not an anti-police rant. They use the same procedures if involved in an off-duty shooting. Almost all policemen on duty don't make a statement without representation.

In God We Trust . . . and our lawyer does the talking.
Don't let them shake you. Hopefully none of us will ever need this advice. Hopefully we'll never need our fire insurance, but most of us have it.

Magazine conversion - RimfireCentral.com Forums: "Chief Says . '' better to make your own . As you can see with my 10-22 lr converted to 22 magnum , one needs the magazine chum is asking about .
Especially if ya have a ' 2 chambered barrel ' 22 lr on one end 22 magnum om the other. With the BC backpacker stock , ya can switch calibers in less than 30 seconds.
Or you can go 17hmr or 17m2 or 14m3. Best to have cantilever mounts on the barrels . each having its own scope."

Magazine conversion - RimfireCentral.com Forums

Magazine conversion - RimfireCentral.com Forums: "Chief Says , First you must have a gun capable of firing any rimfire round with just a barrel and magazine change. One needs a setup that doesnt require a complette disassembly of the weapon.
My conversion trigger assembly allows for the larger magnum magazine and also allows you to shoot the magnum (17HMR) and others with the same receiver. Alterations to the receiver only require two small cuts to get the mag to fit. Once you get the action , trigger, ect you need a way to swiftly change barrels. I choose the BC backpacker stock as it always secures the barrel perfect. I testted this stock ( system) and acrually tried to wear it out. It held up to alot of punishment and still works flawlessly.
The double chambered barrel was just one of my ideas , allowing the shooter to carry one barrel and have choice of 22 magnum anfd 22 LR .
The initial plan was to have each caliber barrel setup with a cantilever mount and each having its own scope. Thus no need to re-zero upon changing cal."

The piece would be the screw in this picture.

A modified screw that would stick out an extra 3/8' so it could engage the magazine release plunger.

That way I could have a 22lr magazine that would work in my 77/22 magnum magwell. Then I could get a 22lr or 17m2 barrel for it and not have to single load.

This would also come in handy on a 96."

i've got a 96/22mag[num] that i use for all 4 rimfire cals..

i had a rfc member machine me a hex nut for the mag that was an extra .375" longer than stock.... it held the mag forward just fine, but allow the mag to move against the mag latch just a touch too much when the empty brass hit the ejector on the feed lips....

so, i made a removable block that fits on the rear of the mag and keeps it from moving rearward against the mag latch spring.... i just used a piece of .375" phenolic... i drilled it for the "tit" on the rear of the mag, and epoxied a section of brass rod in the other face to match the mag latch.... i posted a pic of it around here somewhere....i think it was in a thread re: lightend hammers...i slip the block on the rear of the mag as i insert it...it's workin just fine

77/22 All Weather Mag to LR? - RimfireCentral.com Forums

77/22 All Weather Mag to LR? - RimfireCentral.com Forums: "i've recently begun working on my 4 caliber 'critter gitter'....lol... a 96/22mag action, w/ a selection of bbls for the cals/ammo.... i'm up to 5 bbls now!... (gotta have a smoothbore for bird shot!)

the issue of the firing pin is one that will be literally 'hit or miss' from the factory.....the good news is you can tweak them and make them work

the magazines are no big prob..... i made a .350' spacer out of some flat micarta to fit behind my lr mags, w/ a dimple on one face, and a tit on the other for the mag latch....i'm hoping someone will produce another batch of the 6 sided nuts on the rear of the mag .350' longer..... i heard a rumor someone has made a batch, but i've been unable to lay hands on any....

i've only made one range trip w/ this gun, i've only shot the .22mag and .17hmr bbls.....i do use a set screw in my vblock, and didn't notice alot of change in point of impact when i changed..... i was only shooting for groups, so i don't have an exact measure of how close it was in repeatability.... it seemed to be about what i remember getting when i remove/remount a single bbl....

now, if we can get one of these engineers around here to come up with a nice front sight base to cover a bbl tenon/vnotch, and we can reduce our bbl count by half!!!..... those double chambered bbls in the 'box o bbls' may have found their home!!! .17hmr-.17m2, .22lr-.22mag...

keep us posted on how this works for ya....i'm very interested in these conversions

77/22 All Weather Mag to LR? - RimfireCentral.com Forums

77/22 All Weather Mag to LR? - RimfireCentral.com Forums: "i have a multi-caliber set-up using a 77/17 (magnum action) to shoot 17m2, 17hmr, and 22mag. all i need to do to switch barrels / calibers is to remove the barrel and switch (15-20 minutes). although an option, i did not replace the triggerguard. instead, i use either a modified magazine or install an extended plunger. won't go into detail here (too long) but if you're that interested in doing it, read the following links to help guide you through the process:

http://www.jesseshunting.com/forums/...howtopic=73585

here's some more info switching from lr to mag and vice versa:

http://www.rimfirecentral.com/forums...d.php?t=127843

as stated earlier, there are dimensional differences between the lr (17m2,22lr)and mag (17hmr,22mag) when it comes to rim thickness and rim diameter. there are ways to address this issue.

there are a few here that have played with the 'switch' or 'multi-caliber set-up' and i'm sure they will eventually provide you with some type of feedback and insight on how they pulled it off. if they don't, use the search function and you'll be able to retrieve past posts about the conversion.

good luck and enjoy!
