Much appreciated! The part that I'm worried about it the drilling but, I'm sure if I am meticulous with the measurements there shouldn't be a problem.
With the M4s what size drill bit did you use? 3.5mm/3.8mm or the full 4mm because the t nuts are flush in the hole? Or, is 4mm the internal measurement of the t nut (so, eg 4.1mm would be the drill bit if you want the hole flush? (bit lazy of me to ask instead of just doing the sums lol.)
I'm not sure what you meant on the side note, I didn't even know you could fit a heel lift into hockey boots! Is that to achieve a more aggressive stance or something?
I think I'm gonna go with allen bolts rather than screws to get consistent torque when fitting but yeah using a 12mm and getting good purchase on the t nuts/ foot bed is a great tip! 100% gonna use.
In my mind, doing your own conversions is one of these mythical skills people are in awe of. A bit like re spoke-ing/building a bike wheel. People think its difficult and are put off. But yet when you do it, its both a pleasure and surprisingly easy.. Says the guy who hasn't attempted it yet! :D
Thanks again
