Not sure it's called the big jim system. Others have been using it for a while also.

I called Big Jim system because I have great respect for the master and his work and especially his kindness that he shows. This system is used by many and did not make sense to appoint all of them. It is important to recognize the system ,,,so    :help:

I haven't had either of those two systems so can't really comment. I DO have Shrews and Griffins with the bow-bolt system.  It wasn't on your poll though.

I think it's called a tenon and socket. I don't have either,but i've heard that the tenon and socket is a heck of a system. If I ever get a two piece that is the type I would get. Big Jim shows a video of him wrapping a sleeve if you would like to see it Milan. It is on his website. Go to his hompage and click on videos.

I have the locket socket on my Black Widow PLX,same as Big Jim uses and some other bowyers.I feel it is the strongest system out there.I have seen it on some heavy poundage bows,that to me is a good system.I don't think I have heard of one failing.

I have done almost all the prep to start making a bow for me ie bows. But nothing professional in the sense that I want to live of this, but as a hobby. I personally like a lot system that uses Black Widow and Big Jim.

I am in the process of building a two piece bow of 140 +- using the socket system (I don't really have a name for it and can lay no claim to any of it's design...but I sure like it).

Thanks, bigjim

Tonight I watched the three times , videos on how you're making a two-piece bow. I barely had time to sleep!

I struggle between the desire to make my bow, and to order from you Buffalo 2 pcs     :banghead:

Both work well, Big Jim was not the first to use the slide together system, many bowyers had been doing that for a long time.

Anybody made a Hill style longbow with the BigJim/Locket Socket etc. sleeve?

I am going to try that this spring but I'm curious if it's been done.  I'm not sure if there is enough material on my grips that are about an inch thick.

I may reinforce it with an I beam of fiberglass.

I think Harrelson made a Hill style like that...I may be wrong.  [edit] I was wrong Harrison.....

Jack Harrison used this type of joint for his newer two piece bows, both reflex deflex and his hill style bows, and taught many other bowyers how to make it this way also, my HSS is not made from fiberglass but made from carbon fiber. What I like about the unnamed system is it does not depend on the string to keep it, where as the metal hinge system mentioned above does, however I would imagine that the metal to metal system might be stronger or wear better ?, but this is unknown to me to be an accurate statement.

Maybe is better for Hill bow to use hinge
like on this link    HINGE (http://www.dickwightman.com/archeryactivity/bowbuilding/connexionhinge/practiceinstallation.html)

yup , is very good system but is highly expensive !!!
This bow cost in minimum $1500 ,because to make this bow - you need very good machines ! And highly professional bowyer . I want to say is not easy to make Wolverine  .
I have two choice
1 fiberglass socket ( BW , BigJim, ect,,,,)
2. or system for tomahawk two pcs

hinge don't look nice

BW's DVD that accompanies it's bows has some additional segments that include one of Ken Beck using a gauged hydraulic press to test the deflection and breaking point of BW'S Locket - socket compared to a solid riser of the same construction.   They tested identically.  

Larry Hannify at A&H told me that their test results matched BW's.  

Big Jim uses the same system.

BigJim is one of the BEST ! I spend a lot of time in the workshop and I know how to identify a dangerous good master    :clapper:  He knows what he's doing

As long as you reinforce the riser before making the bow, there should be no issue in doing a hill style with the fiberglass socket system.

The Harrison system is not carbon, it just has a carbon wrap over the male portion of the sleave. I do use carbon in mine too, but it is not really necessary as the socket itself is already excessively strong. Don't reinforce the riser for your two piece, expect to have problems...maybe not on light lb bows, but why take the chance.

thanks, bigjim

I really like the socket that Big Jim uses, slickest TD system out there.

I shoot a Big Jim Buffalo 2 piece and find it as solid as any one piece bow.

Post by: typical2 on November 18, 2013, 06:32:00 PM
Well...bigjim, I just ordered some fiberglass earlier today to reinforce some Hill style risers for some socket style 2 pieces.  Just need to watch your videos a few more times before I tackle one.

The takedown system like Big Jims is stronger than the bow. You can check a video of this here and watch the bow explode before the takedown system.

The Hinge system has 2 screws per side right? That kinda scares me. I have a plx with the sleeve TD, and it feels rock solid.

both outstanding when done right...safest...?  BOTH... :)   I have owned several of both from BW PLs to Great Northerns and Robertsons...I prefer the FEEL of the "Locket Socket" but both work very well.

I've heard of three friends bows breaking with the hinge.
