The drill blocks are great but you can buy an awful lot of drill bits for $26….
I’ve done both methods more times than I can count, they both work fine but you’ll break just as many bits either way if you don’t drill straight and keep them lubricated.
I really like the way Walt trims the cotter pins and bends them back, that’s slick for things like brake calipers that don’t get moved around much. I’ve found that high quality stainless safety wire with the special pliers makes a quick and neat job as well but there again you’re spending money that could be used for tires ;)
This would make a great sticky too, I can’t count how many times I’ve seen folks get turned away from the track because things aren’t secured properly. Good work Gif!!!!
