I really wanted to slow down the accumulation of the byproducts of cutting wood on my honeycomb bed. I figured I’d need to raise the work a little and found some spikes (used to put spike studs on clothes). My first attempt was to mount them onto magnets, but the magnets wouldn’t align the way I wanted them all the time. Instead, I found 1/4” x 3/4” pop rivets and modified them. These fit into the openings in the honeycomb bed with the stud raising the work 13mm above the bed. This has shown to give me much cleaner results (less flashback as well as honeycomb bed) than before. I’ve include some pictures that show the original pop rivet, the pop rivet with the pin driven out, the assembled pop rivet with the spike, and the assembly in one of the holes in my honeycomb bed. This ends up giving me almost a bed of nails, but still allows air flow down through the honeycomb where the standoffs aren’t placed. I’ve also included a couple of picture of the edge holder for 3mm wood that I created using my CNC machine. The magnet shown in the picture is a 60mm x 10mm x 3mm one that holds the holder in place on the steel honeycomb.
Nice! Where did you get the spikes?
Everything I used I got from Amazon. I’ll list the item numbers below:
Spikes: B0B56FCT1H (Note: about 10% are defective, but I was able to find enough for what I wanted)
M3x25mm screws: B0CTMH33L1
Magnets: B07DFZH4WT
Pop rivets: B09YY8L875
Note that the spikes are difficult to hold when screwing on the bolts. I used a pair of pliers to hold the edges of the spikes while using a screwdriver to tighten the bolt.
I like using the rivets to work with honeycomb. I use spikes on magnets with a steel pegboard - super cheep, easy to work with - no flashback.
Note that you can get taller spikes - mine are about 20mm (.8 inch) tall which lets more air under and believe reflects any laser at a greater angle.
These are what I used - 100 for about $9
I had looked at the longer spikes, but that limits the height of the material being worked. These work well and I haven’t had any airflow problems. YMMV
