Hi all;
I don't usually do any work on Sundays, but this piece had been sitting around for a while with instructions from Mike (mgmlvks) to see if I could fix it up when I had some spare time.  It is a little fuel filler cap from a 242, and whomever had it before Mike used "special" knurl-removing pliers to tighten it or loosen it, as the case may be. 

[49731561823_030519a4d7_z]

So, yuk, huh? 
I told him I would try to figure out something, but just re-knurling it presented the problem of crushing the fuel cap.  Knurling is a very high pressure process, and the fuel cap is thin walled. 
Here's my one hour SOnday solution:

1.jpg 
Gently chucked up and turned off as much of the old pliers marks as possible without cutting clear through into the inside threads.



2.jpg 
I knurled up a piece of 3/4" brass stock for the next step.  Forgot to take a pic of the actual knurling, but here is the result.



3.jpg 
Drilled a starter hole in the knurled end and then bored it out to be just a bit of a push fit with the turned down fuel cap.  A push fit is just what it sounds like:  You have to put some pressure on the pieces going together, but it is not actually like a press fit, which is a hard press.  On this one I cut it so I could just barely push the fuel cap into the knurled piece by hand.  Just short of a hard interference fit.  A hard press fit would have likely split the knurled piece, ruining the work.



4.jpg 
The trial fit.  At this point it's starting to get stuck, so I pulled it back out  in order to be able to part off the knurled piece.



5.jpg 
And there we go.  The piece parted off.  I went at this very slowly, as sometimes parting thin walled sections will end up crushing the piece being parted due to tool pressure.



6.jpg 
And the finished result.  I used just a bit of Locktite to augment the push fit so there will be no coming loose. 

Hope this works well for you, Mike.  I'll mail it next time I get to the PO.

Thanks for having a look,

Dean

I could be wrong, but I think that cap came to me like Dean got it from Mike.  It came off a 242nl with a compromised fount.  SteveRetherford eventually ended up with useable upper parts last fall/winter.

long story short, I sold the lantern and the new owner didn’t want the beat up cap so I switched it out.  It was found the fount was bad.  I bought it back and parted it out.  Mike asked after boogered 242 caps for a project so this ended up with him.

Hey! I happen to have a pair of those pliers around here somewheres! Didn't know they was all that special.

Pretty impressive lathe work, Dean! A fellow would have to look pretty close to know that isn't one piece.

I didn't realize that knurling was impressed, if it is. I always assumed it was cut, but have never seen the process.
It's priceless until someone puts a price on it.

WOW!  Just WOW!  This was more an experiment than anything else - and Dean comes through AWESOMELY as always.  I hate throwing away parts as each one is one less for all of us.  I believe there are repro 242 sized caps out there - and maybe this is more a re-manufactured cap.  I was just trying to find a way to make them live again - pretty sure this is NOT cost effective at this time - but in a few years?  Who Knows.

Thanks Dean and John for making this possible.  And I admit I have pliered a few things in my time, but GPA's and CCF have taught me new skills including patience!

Bill (austin65), here are a couple of pics of one of my knurlers. 

7.jpg 


8.jpg 

This one is a scissors type.  One wheel has teeth angled in one direction and the other in the opposite direction.  This is how diamond knurls are made.  There are also wheels that are just straight teeth, like the kind used to make 242 ball nuts.  I have a few different knurlers. 
The round stock is held in the chuck and as the chuck spins the knurlers are tightened down on the stock.

Timm, it's a forming process, called "upsetting".  The material is actually squeezed up out of the surface of parent stock.  When you knurl something in this way, the diameter of the stock get larger.  In some assemblies knurling is used to make a diameter larger for a hard press on interference fits to hold parts together basically forever.

Some knurling videos on youtube - none as good as Deans pics - but this one gives a sense of the operation - start about 7 minutes to miss the set-up.  Watch at higher speed does not hurt !  Delete the spaces between // and you to get the vid, or for most folk just click on the 2nd part below.

I like it! I never knew how they knurled stuff but seeing that tool now clears things up for me.

I’m not anything near a machinist nor could I ever have hope to have half Deans skills so I m asking this Just for some knowledge. Could you have threaded the brass rod and screwed the cap on there and reknurled it or would the cap still deform or become to thing to be trustworthy?

Hi Joe;
Mike and I talked about trying something like that, but the cap was so chewed up it wasn't even all around.  I don't think the knurls would have looked good at all.  Also, once it gets just so thin, the knurler would start to deform the inside of the piece.  It might not come off the threaded piece that the cap was screwed onto at all.

That was a great job done. Another piece saved. The piece is still original. Wished I have these machining skills and a workshop with all the necessary toolings to do this myself.
I've had some brass nuts turned out and knurled in a machine shop before. Yes, its certainly a high pressure process and would certainly deform the original filler cap if it was re-knurled directly. Like Dean hinted, the inner threads would have been messed up too.

Hi Dean,  Great work!

I was going to ask the same Q Joe did, but I would have suggested a steel mandrel for the support core.  I've never tried knurling brass over a marred up surface that I can recall though (For a while I was knurling EVERYTHING... even my dads old reloading press handle - solid steel, no plastic grip...),  and your comment about "will it come off the mandrel" is a good point.

Maybe with a hardwood cap fixture like was discussed in another thread for gasket removal would make it doable?

Those three pattern knurlers are generally left to heavy lathes, since they put a lot of stress on spindle bearings in the lathe head stock and on the lead screw in the cross slide.  I don't know how large your lathe is, but if it is quite large, making a tool post for it to hold the three-way would be the best bet.
