Having issues using 8mm hardware w/ Armstrong boards. The tracks are just slightly too narrow for 8mm t-nuts to slide freely or even fit into the track at all. i.e. FoilDrive t-nuts are very consistent (8.92mm +/- 0.01mm) in the width that fits into the slot but the Armstrong board at the surface (where I can measure) is 8.51mm. Have seen this issue w/ 3 Armstrong boards over a 4 year spread. Bought some FoilLite 8mm hardware and can’t even get them down into the track because they are slightly more rectangular and the corners catch before I can slot them through the Armstrong specific opening “()” and into the track. Debating sanding the track slots wider so I can use more available 8mm hardware.
Aren’t there industry standards for track dimensions that manufacturers follow?
Had that problem with a prone board from them. T-nut would slide for adjusting the mast, but would get seriously stuck once cinched down on one side only. They supposedly mold their own carbon tracks, so I guess they have a habit of not checking tollerances… If still under warranty, I’d email for directions. Otherwise, 80 grit wrapped around a wood ruler or paint stick should do the trick.
Don’t understand why people fall for the marketing and buy Armstrong or other Chinese mass produced boards when they could get a high quality hand shaped board like apple tree, amos, kalama, etc.. for the same price
Sand the edges of the t-nut itself with a metal file vs trying to sand the inside of the tracks, much easier. I had this issue with my new Amos tow board, and filing the t-nuts down a bit did the trick.
The tracks on Armstrong boards are a little narrow and while they are deep in the middle and will usually take up to 30mm bolts, the actual track slot area where the T-nuts rest is not very deep. My don’t slide freely, but I can push them along with a tool, so no complaints. You just have to try different T-nuts that’ll fit better.
I had same problem one end of one track, and friend did too. We found stainless steel Duotone and AFS track nuts worked as the narrowness was only towards the top of the track.
