Is there any consensus on how many holes to put in a board?
Mostly concerned with the touring bracket, now that the Voile binding pucks are two nice spread-apart holes (ayo). I see no need for t-bolts on the heel lifter.

Havant seen any one post about a broken board ever from tnuting. The biggest influence all the holes have is "probably" in the way the base rides. I used quiver killers for my touring brackets, but i can see these possibly ripping out if you go over the fount...

s o b I would t nut everything. Not worth the risk of things failing in the BC There is a lot of talk about "swiss cheese" boards but i've made heaps and none have snapped. The risk is more when you go for adjustable stance, but most of the DIY board suppliers offer this. Id just make sure your board has a good wood core and is stiff before spliting it.

Thanks for the input. I do have reports of two DIY splits breaking at the touring bracket. Same guy though, and from what I can tell he puts his gear through way more than I do.
I've got a tentative offer to go through the top on the remaining holes with some helicoil inserts. I think I'll go that route on the remaining holes, if the opportunity presents itself. Until then, I'll stick with two tbolts on the touring brackets and wood screws on the risers.

I went with wood screws for the heel risers on my first DIY & it's still kicking. The second though I went with T-nuts throughout for that factory look (& makes swapping hardware a little easier).

What if you don't cut through the glass on the insert flange. So the insert would be visible on the base. I you have a 3/8 hole as opposed to a 3/4 you have way more strength.
