KISS, MYOG, 5 ounce Pack Frame

Paul,

I used the edge of a 4’diameter lawn furniture plastic table.

I turned the table sidewise and started from the mid point of the tubing.  I would press down firmly with both hands, move a few inches toward the tubing ends with both hands, repeat, etc.

The tubing would spring back each time I pressed it down and it fell short of taking the shape of a 4′ diameter circle.  By the time I got to the ends it was bent sufficiently to meet my needs, however.

.

A perfect KISS solution. I wasn thinking of using a 55 gallon barrel but your idea was much better.

CORRECTION

Just used a micrometer to measure the od of 3/8″ nylon barbed tees.  They are actually .05 inches larger than 3/8″ (..425″ instead of .0375″).  So aluminum tubing needs to have .425 id or larger to easily fit over the tee.

I think they add .a bit to all sizes of  tees so they fit flexible plastic pipe tightly.

(I hope people see this before they buy any tubing to fit a particular  tee..  One could sand off the .05 nylon but what a hassle.  Site won’t let me edit any of the posts from the first page so I can’t make a note where it would be most useful.)

Any suggestion for where to get the aluminum tubing, D&D?

dk,

No help on aluminum tubing source.  I used some I already had that I acquired 40 years ago.

Daryl,

3/8″ OD on the tubing . What is the ID? (I hope I didn’t just miss it above.)

My handfull of used Easton arrows came yesterday. I quickly learned that I will need to fill them with sand and bend them slowly. I wanted to see how much it would take to break one and it broke much quicker than I expected.

Paul,

“3/8″ OD on the tubing”3/8″ is the named size of the nylon plumbing tees.  The actual OD of the tees is .425″ however, not .375″

“What is the ID?” Looks like the id of the 3/8″ nylon plumbing tees in the KISS mock-up is about .3″.  I don’t think id is consistent from one brand to another, however, because plastic pipe  only goes on the outside of the tees, not the inside. .

The aluminum tubing in the KISS mock-up is 1/2 “OD and .425″ID.  It fits over the tees so any ID => than .425” would work.  OD isn’t critical relative to fit.

Pole OD greater than or equal to .425″.

So 11mm OD it is!

Got it. Thanks

Paul,

On the KISS mock-up the aluminum tubing needs to be .425″ inside dimension (ID) or greater so it will fit over the nylon tee.

Note to self:

1.) Do not post after the sleeping pill has kicked in,

2.) Do not just enjoy the pretty pictures, study them, and

3.) remember, that getting old sucks…..even if I often cannot really remember that.

Thanks much Daryl

Paul,

Thanks for the laugh.

Hi, Daryl,

I like your simple and elegant design.  I also like the addition of the front pack.  I was unaware of the Aarn stuff as well until I saw it in one of these threads, but all their stuff is quite heavy.  The off-balance nature of a backpack, even if it only weighs 20Lbs. has annoyed me as I’ve gotten older.

A couple of questions for you;  Is the front pack only buckled on after the the rest of the pack is on?  How do you put it on (the main pack) if there are no shoulder straps?  Lastly, why did you move to a padded hip belt?  In the original thread, I seem to recall you saying the unpadded hip belt was quite comfortable.

Regards,

Craig

Is the front pack only buckled on after the rest of the pack is on?   How do you put it on (the main pack) if there are no shoulder straps?

When using the front bag without shoulder straps It would be buckled on before putting on the rest of the pack.  Only when using shoulder straps (in addition to the front pack) does one have the luxury of buckling the front pack on after putting on the rest of the pack.

My current padded shoulder straps only weigh about 2 ounces so I usually put them on the pack in addition to the front bag.  Gives me the option of using the pack without the front bag.  The front bag straps are separate from the shoulder straps. 

The shoulder strap tops attach to the cross  bar, not the nylon corner tees.  The shoulder strap bottoms attach to the same nylon bottom tees as the front bag. 

The front bag is connected directly to the nylon tees that are at the 4 corners of the pack frame.  Two straps go from the front bag top corners  and two go from somewhere near the front bag bottom corners.  

The top two front bag straps carry the weight of the front bag.  The bottom two straps keep the bag from swinging.

Lastly, why did you move to a padded hip belt? In the original thread, I seem to recall you saying the unpadded hip belt was quite comfortable.

Yes, it was quite comfortable.  This belt is a mesh hat/helmet ? band I bought at a military surplus store.  When  I tried to replicate it I couldn’t locate or replicate the special mesh they used. I also found it difficult to produce the perfect fit  on my wife and friend.  So I switched over to a simpler padded version.
