Plastic Dominoes?

[jbair]

So I've been wondering how it would work out to have various dominoes made up by a plastic injection molding company in the various sizes and lengths for dry assemblies. Maybe incorporate a hole for inserting a tool to remove them on disassembly. This may not be necessary if specking them .1 or .2 mm thinner than stock. Then I began toying with the idea of drilling a hole lengthwise through the centers of the ends to use as aligners with "knockdown" assemblies. Maybe color coding the plastic to match the cutter color coding and all that. Sound useful to anyone else?

I don't have the Domino....YET....but is t it important for the domino or in my case currently, dowel, to expand with the glue creating a tighter fit?  Could you get the same fit with the plastic?

I just lightly sanded a couple different sized dominos for dry fit assembly.  With a red sharpie I wrote "test" on them so I don't use them.

I'd do an extrusion rather than injection molding for that. You'll get much better yields and it should be quite a bit cheaper to boot.

Do they make pvc dominos for exterior pvc trim?

No. But you can make your own easly.

I've done the same but I've written the size in magic marker. It makes it easy to see which size the test domino is and a reminder not to use them.

The first time I dry fitted an assembly, I had an extremely difficult time getting it apart without damaging my projetct. Immediately after that, I lightly sanded down a set of dominos for assembly purposes. I think most Domino owners have gone that route. Sure, you could go the plastic domino route, but that would take time and money. I bet you could even market them. But, for most the do it yourself set is the easiest, cheapest way go.

True, just wondered.

Actually, guys suggesting this is what got me thinking about having plastic ones made instead of using the actual dominoes. I figured even after sanding, with humidity changes there'll be times the "test" dominoes still get pretty snug if you leave them close enough to spec to hold together a dry assembly. The suggestion in this thread to "roll my own" with PVC may be the answer I was looking for. Make an assortment out of PVC, Mark with Sharpie for easy size ID and have them available. I like it.
