Thanks for that, pretty cool. My two 754's were originally delivered to Texas Instruments and Virginia PolyTech University. The newer one was delivered in April '99 -? it's a B032XXX. So looks like

Re: I would like some input on a good wire forming tool.
Slide the tool until the outside is just inside the holes for the part on the board. Use that notch. If you have the lead bending tool (the one with the thumbwheel), then there are tips much like a

I've always (50+ years) used one of these: https://www.travers.com/soldering-aidfrksplice-ttc/p/99-004-252/ They no longer sell them but I'm sure others do. I got a bunch on closeout from Travers for

Re: I would like some input on a good wire forming tool.
The largest problem I have found with the plastic bending guides is they are too large, with the pocket that the component fits into too small. They worked very well when component densities were

Re: I would like some input on a good wire forming tool.
Select the proper notch, insert part and push the leads down until they are parallel to the tool. That set has multiple widths to make it easier than the old design, where you had to center some parts

Re: I would like some input on a good wire forming tool.
I used a pair of needle nose to bend the leads, prior to find the block. I would simply find out how far from the tip would give the proper length, and bend the leads one at a time, but the block was

Like Chuck, I have one of these https://uk.rs-online.com/web/p/pcb-lead-cutting-forming-equipment/0545109/ They seem to have got very expensive. 20 years or so, when many more components were leaded

Re: I would like some input on a good wire forming tool.
They are used to bend the leads on an axial part, that will lay down on the PCB, so that they will fit the spacing of the holes in the board. You put the axial part in the middle of the guide, with
