Top Bows

 

Looks like I need the tube to be more correct for my 48  CJ2A #206759

 

Anyone who need the rod type, lets work a trade...

 

I just came in from checking the bow slope theory with my original half cab bows, and as the Famous Ed McMann always said...You Sir...are correct!

 

Roger,  Some time (when you can), please tell me the hole location that you have.

If anyone has a tube spacer like the one in the link could you check this for me please?

 

Another Note:

I found out last night , while I was swagging the center bow ends, that the reason some of you guys are getting .096 readings on the wall thickness of your center bow is because of the swag.  When the end is swagged, the metal grows on the end.

 

One more question:

How tight are the center bow & side bow sockets when they are assembled?  Whe the center bow seats to the rivet, is it still loose?  Mine slide in pretty snug (but not too snug). It occured to me that about 1/2" of paint will get scratched off in this area.

The center bow is snug at least.  On one side of mine, it's very tight.  I have to twist back and forth a few times to get it to seat on the rivet.  And the paint is definitely worn off in that area.

I put that picture in CAD and it looks like the hole is 1-1/4" from the beginning of the bend.  Does anyone know which generation this started 2 or 3?  I'll add the hole to the drawing and a notation about the generation when I get confirmation of which gen had these holes.  The bows I make will not have these holes.  I also see that the degree angle of your bow is 83 deg.  Another inconsistency.  We have 83, 84, & 85.  It's easy to tweak your bow if you want to change the angle.

 

Tube spacer:

I don't think that hole serves a purpose either except for a place to hang it in the paint booth.  I guess I'll put it in 7/32 on center from the edge of the tab.  That will leave 1/8 of meat between the hole and the edge of the part.

 

This is how to make the bend in the end of the tube spacer:

 

Now when it's finished it dimples the metal like this:

 

 

I didn't see that dimple in Roger's  but his pictures didn't show that angle.  His are 14ga (or thicker).  Maybe that material won't do that.  This is 3/4"dia 16ga material.  when I get the 5/8" material in I will have to make a new jig anyway I'll work on this dimple when I do that.  I tried to get 5/8" dia material for these first orders, but the mill had already started on my order so I could not get it in.  I have to order the steel in bulk or it costs too much so when I order material for "B" list, I'll get some extra 5/8" dia tube.  So the first sets will have 3/4" dia tube.  If anyone from the "A" lists want's the 5/8 tube spacer,  I'll sell you one at cost.  The 3/4" tube spacer will fit in you storage bracket on the windshield.  In the mean time, I hate to use the "M" word but you could do an MDJaun and put some bondo in this spot to make it look full.  I don't think that this particular area will come in contact with anything.  I will experiment but I may not be able to control this.  The metal goes where it wants to.
