Hi all,

One of my inserts is galled and I'm after an intermediate and bottoming tap to clean it out. Costs an arm and a leg to buy a decent tap set just to use one or two bits of it once so if you have or know of someone who has some taps please let me know with a PM or call/text 0432 902 185.

Cheers,

Brendan

Me to mate got a full set in Reservoir at my work give me a buzz if you want 0423 384 934. Or you could head down to cost less bolts or any industrial supplies, shouldn't cost more than $20 for a 5.2 mm drill bit and a 6 mm tap. You might need to redrill and up the thread size.

No pics but I'll try to explain.

Definition from the interweb: Galling is a condition whereby excessive friction between high spots results in localized welding with subsequent splitting and a further roughening of rubbing surfaces of one or both of two mating parts.

Occasionally happens with screws and inserts. When it does, the male part tends to come off worse and not repairable, but the female part - in this case the insert - just has some crud wedged in the thread pretty firmly.

A tap is a tool used for cutting a thread into a hole. By carefully running a tap through the galled female part you clean out the extra metal and restore the thread.

Because kiteboard inserts are blind - the hole doesn't go right through - you need a bottoming tap which has minimal taper so it can cut to the bottom of the hole.

Hope that wasn't too simplistic an explanation??

In this process I found out that although all my previous boards have had metric inserts - cardboard, nobile, underground, cabrinha, - slingshot and liquid force boards run whitworth threads (an imperial based sizing).

Anyway, in a few years of kiting and lots of stuffing about with pads and straps and stances this has only happened once, and was easily fixed so nothing to be too concerned about.
