Warbringer Nemesis #7 - Pinning the Femoral Head

Short Post today.


I was going to do something longer on putting the whole pelvis/waist assembly together, but I decided that first I should go into some detail about how I pinned the tops of the Warbringer's "femurs."  And that information would make the pelvis thing too long.

The Warbringer's femurs are similar to that of a Reaver Titan's in that they are primarily a series of pistons.  In the Reaver's case, one large and two small.  For the Warbringer, two large and one small.

These pistons, now and in all future references just for the Warbringer, are molded into the knee joint and the top part of the femur as shown in pictures below:

 

These pieces have pretty decent surface area coverage for glue, but I decided that they should also be pinned because they will carry a lot of weight, and bear a minor jolt every time I put the upper torso onto the legs.

I achieved this by pinning each of the three pistons.  After I glued them with JB Weld of course.

 For the front piston, I drilled a 1/8" hole diagonally up the piston into the socket.  Not all the way into the socket though.  Although that would have been okay too.

Like so.  I chose the 1/8" rod for this pin because the front piston is going to be mostly covered up by the Warbringer's armor plate.

That will totally cover up the hole!

Next I drilled a 1/16" hole in the rear piston.

I chose a smaller size pin this time because the rear piston will remain visible, so I wanted the hole to be fairly unobtrusive.

This time I did accidentally drill all the way up into the socket.  It was fine though, all of this is going to be sealed in by the hip connectors.  Or pelvis connectors?  Titans are not totally human shaped.

I drilled a 1/16" hole in the inner piston as well (there is no outer piston).  This piston is molded to the upper socket, so I drilled down into the knee joint here.

Then it was a simple matter of inserting sanded brass rod coated in thick super glue, waiting for that dry, and filling the holes with two part green epoxy.

I failed to document that step.  But it really is very simple.

Come to think of it, we have not really discussed two part epoxy, or green stuff (okay, sometimes it is green stuff).  I use the Army Painter stuff because the last time I ran out was around a NOVA Open and the Atlantis Games and Comics booth had that kind.  It works fine for me, but I cannot comment on its quality versus other variants.

There are a lot of guides for using green stuff out there, so for the time being I am not writing one.  If anyone is interested in that, I can.  If I think about useful tips while I am detailing this build, I will let you know.  Right now, I have none.
