To join the sections together he uses "table pins" to align the modular sections. I found several suppliers. One source is Amazon. https://www.amazon.com/Hafele-America-Table-Pins-10/dp/B003FHOQ6O He uses 2 part epoxy to fasten the table pins in place. May be something to look into.

The real problem with using locator pins on your modules is not so much sourcing the pins as it is getting them accurately and consistently located on the modules. If the same two modules are always mated to each other, then it's a simple matter of clamping them together, drilling the hole, and installing the pins. However, if you have several modules that you wish to drill and dowel so that they can fit together in any combination, the problem is not so simple, since just drilling the holes so that they are plumb in two planes is difficult to do with just a hand drill, you really need a drill press or milling machine to get them square to the world. Just being off a degree or two can cause problems. Then there is the question of getting them in exactly the same location on every endplate, it's just not that easy. Also, the chances of different builders in different parts of the world each making their modules with the same size holes in the correct locations is even less likely. Using module kits that are laser-cut or CNC milled by the same manufacturer is almost a necessity, and even then, there is little room for error.

A simple hole jig made from metal will take care of the problem. That's how it was done in the pre-computer and CNC days.

A Jig is the best way to go if you need uniform placement.

There are dowel centering pins that you can use.

But the simplest solution that I can think of is:

Align the two pieces of wood and clamp them together.

Then, drive a nail or screw through them.

Extract the nail/screw.

Unclamp and use the nail/screw hole to locate your alignment pins.

All great ideas so far.

Here's a couple of videos of a German guy with an HOn30 modular layout. I'm impressed with his method of how modular his layout is.

The video link does not show at all on my iPad, is it in adobe "flash" format? Can you post the actual URL address written out?

Thanks...
