Title: Needed accessory
Post by: RJ HEDLEY on May 31, 2004, 06:21:29 PM
 
   ***Mr. Rohrbaugh, are you following this forum?***
 A tool to assist in disassembly/ reassembly.  Remember the little Seecamp used a .32 round in a *stovepipe* position, to align the *take down pin* ?   Why can't we have a small block of aluminum dimensioned to the correct size,  maybe in a *T*shape, so in won't fall through.

RJ,

I think you're on to something.  It could be brightly colored and serve an additional purpose of a "chamber unloaded plug" when the weapon is stored.

A plastic orange device -- similar in nature -- was included with a S&W Model 669 I owned many years ago.

To help with disassembly I whittled a dowel down to size to stick into the chamber like a stovepipe. This keeps the slide in the right position to punch out the pin for disassembly, and it works fine. But it seems like a really crude tool to use in taking a beautifully machined pistol apart. What are the rest of you early owners using to help make disassembly easier?

Nothing. But I need to do something. This is an item that Rohrbaugh should make and sell.

I just got my R9S today.  I barely have the hand strength to hold back the slide to align the pin hole for disassembly.  Don't know if I'll still have the strength to do so in a year or so.  If anyone has determined an item that can be used for this function, please share.

When I get mine, I will make a device available for any that want it.  If it is simple enough, they will be free.  
 I said *if* :)

Maybe some one could turn a metal rod on a lathe to the correct thickness and then cut off 1 inch lengths.

This is an issue that Rohrbaugh should deal with soon.

I've gotten a lot better at assembly/disassembly since doing what the Marine Corps taught me to do many years ago.  I spent last night disasembling and reassembling it about 100 times.  I'm pretty good at it now but would still like one of RJ's gadgets.

I have a lathe and some brass stock but ... not the time to play with it right now.

I think longer term, all Eric and Co need do is sub out to an injection moulding company -- for them to make a real simple ''T'' shaped piece out of polyethylene .... the cross part of the ''T'' would be placed in the open breech, it's forend engaging in chamber mouth .. rear end simply impinging on bolt face.  The rest of said ''T'' of course acts as a simple handle.

Cost?  Once set up .. a few cents .. and it'd make owners happy I think.  Hopefully Eric might see this thread and note the ideas .... if he doesn't find this then we must mention it to him sometime.

For now, I think dowel is simplest quick fix.

 Interesting,  I just tried something on my S&W model 6906.

I pulled the slide back slightly and placed a 9 mm  round in the *stove pipe* position, and guess what?  It was in just the right spot for disassembly.  
 Has anyone tried this with the Rohrbaugh?  If so and it didn't work, what would it take, dimension wise?
Title: Re: Needed accessory
Post by: 9mil.mouse on June 20, 2004, 07:16:26 PM
RJ,  I just tried it, 9mm is too big. The piece of material needs to be just slightly less than 5mm to work. The crude dowel I whittled down for this purpose measures about 4.8mm to 4.9mm in diameter. Anything from 4.7 to 4.9mm would work fine.  

"...what would it take, dimension wise?"

I am getting by pretty well using a slightly amended "glock grip" that eliminates the need for a third hand.  That said, I waiting for those of you more scientifically minded to work this thing out.
Title: Re: Needed accessory
Post by: R9SCarry on June 20, 2004, 08:40:04 PM
Know what ... when I last posted I was just visualizing .. and not checking, imagining slide having to be further back.  I have just done that and 9mil is right ... only about 5mm.

Being quite critical tho ... to gain reliable alignment for pin re-fitting .... would mean quite a close tolerance insert, and I am thinking now of not round bar but flat.  High density polyethylene would still do the job - and would need to be little more than an oblong section short stick .. very basic.

Once I get ahold of one of an R9 (may be awhile...getting ready to order), I would be happy to design and prototype a small batch here in my lab at school.  At the university where I am a grad student, we have about every prototyping cabability you could imagine from cnc machines to stereolithography.  We can even make small batch runs of injection molded plastic parts.  It's amazing to go from a 3D design in my laptop to a production capable part in a few hours.

  I'm not sure how this tool is to be used since I'm still waiting for my R9s to arrive.  Please describe the application and this tools function.
  If a rod of between 4.7 & 4.9 mm diameter will work, this is available from McMaster-Carr  at www.mcmaster.com (an industrial supplier that will sell one piece at a time).  Am I correct that the material should be softer than the slide material so no damage occurs?  If this is so, Nylon may be a good choice.  A 3/16 inch diameter rod will fall between 4.7 & 4.8 millimeters.
  Go to the Mcmaster-Carr web site and look under the "Raw Materials and Springs" heading and pick "Plastics".  Then pick "Rods" under the Form header.  Then pick "Nylon" under the "Material" header.  Then pick "Nylon 6/6" under the "Nylon Materials" header for its description (it is available in .1875 diameter).
  Let me know if this will suit your need. :-/

Post by: R9SCarry on July 03, 2004, 12:33:37 AM
Oscar - this could well work .... however one thing concerns me ...

We will assume, necessarily - that the ''spacer'' is softer material .. certainly Nylon 66 would be fine.  However ... it might take only a small depression in said material to effectively reduce its dia a fraction - enough maybe to take it ''out of tolerance'' for this function.

I personally think a better bet might be (like the end of a chopstick I am using right now) .... a taper piece .. going from say 4.7 thru 5mm over 3/8" or so .. this would allow for exact positioning for everyone .... and allow for compensation should a small groove wear in it.

See what I mean?  Slightly more versatile ... maybe?

~~~~~~~~~~~~~~~~~~~~~

Forgot - said piece acts as a spacer or stop .... when inserted into space between rear of barrel and slide aperture ... at the exact point of slide rearward movement that permits extraction/replacement of slide pin - re disassembly.

Chris:
When you guys with an engineering background work this out please translate and let me know what I need to buy and where I can buy it.  

Does anyone remember the scientist's equation on the blackboard in the movie "The Day the Earth Stood Still?"  Your discussions seem to remind me of that.

Yes, yes...this is a great project for all you engineering types. Yes, please solve this problem for engineering morons like myself. I have enough trouble trying to nail a nail in straight, so while I do not have a clue what you are talking about...figure it out and then as Murray suggests...translate the answer.

A good thought ...

I'm picturing a small slot in my pocket holsters for such a tool and an extra magazine!   ;D  Hint! ;D ;D
Title: Re: Needed accessory
Post by: R9SCarry on July 03, 2004, 02:42:55 PM
Consider this ... just as an example. ..... made from high density polyethylene or Nylon 66 .. something tough ... but also of course best if made thru quick injection process rather than machining.

A 9mm case is just over 3/8" (0.375") ... and so this or not too much longer is what we have to play with when inserting into space behind chamber.  Working on (sorry - going metric briefly) .... around 4.8mm as a safe min dia .... and going up to 5.2mm as a reasonable max dia we then have what I have drawn up... tho with ''normal'' dimensions! :)

For most part, the area of taper around 5mm mark ... near middle of taper - will be the section to use, but with the taper it'll be easier to move slightly in or out - to get optimal position.  Seem useful?  

Maybe even make max dia a tad larger ..... and leave of course a parallel section of inch or so for holding.. this is not all shown.

WOW...I have trouble signing my name, let alone "whipping-up" prototype blueprints. How do we non-engineering types keep you engineering types happy?
Title: Re: Needed accessory
Post by: FJC on August 28, 2004, 12:56:43 AM
Ok, now take your blueprint and go to this site:

http://emachineshop.com/

And you can upload it and have them make the parts for you. :)  Looks like in a quantity of 100 it might be as low as $1.90.  Order 100 of them, sell 'em to all of us for $5 each, and make some scratch for your effort.

:)

(FYI - I know nothing about that site/company, just stumbled across it and it seemed like the solution to getting something specific made).

We ARE quite a bunch here!

Here we are just a few members and we seem to have the skills, knowledge, know how and abilities -- in excess of what Congress,  ::)Harvard  :Pand the Media  :-X have... combined!  :o

OK, I'm IN... will this collection of ideas and resources get us into production?  I'll volunteer to buy a couple of tools and use them for the Beta-Testing phase!
