I didn't make your one like that, Brendan made that one while I stood watching... Here are Joel's instructions but you may have a problem as the 3PMH heads are pre-drilled for the shaft, my shaft was cut too thick so I had to go through all kinds of shit to make the hole bigger (no pillar drill, y'see)... If you don't cut too much off the end of your pole you'll probably be fine, just something to bear in mind... I have some spare 100mm M6 countersunk bolts/nuts, yours for a beer... I've got an M6 rod you can borrow too...
Caroline, if you are using M6, you'll want to make a 13.5mm hole in the top, and 5mm hole in the bottom, and then force the pole through. The point you cut the pole depends on where the nut is sitting, and how long your bolt is (mine are 100mm like Joe)
I can lend you the 13.5mm drill bit if you like, or if you give me the head I'll sort it out for you.
