Hey Derek. Thanks for the kind words! I def find them sturdy. Being hardwood, I find that if I pre drill to exact depths and widths the metal pegs stay put. Plus the tubular hardened brass at that size would take a large amount of pressure before compressing or shearing. I also glue the pegs in the holes top and bottom using a high psi 2 part epoxy, so once the glue sets there is no movement. I’d be more worried that the dowels I used for the glue up would shear off under great force then the pegs moving about. But in order for that to happen you’d need to apply several hundred pounds to even get close.
