Hi guys after trying a few different types of hammer i found the lead to be the best as you dont have to try so hard to hit the wing which improves your accuracy plus if you miss it doesnt ding your rim I have 4 tips for knock ons allways use a lube paste like
zinc or copper this stops the alloy gauling and making a mess of your rims. the other is dont over tighten them with a lead hammer you get it tight with a 3or 4 taps.
make sure you are hitting it the right way and that you have the correct thread direction right on the left and left on the right.
Wazza i have allready made you your lead hammer.
