Quick update
I'll keep an eye out for that stuff to seal it, or cheap equiv.
bit of an update now, I tapped my first bolt hole with great success, something I have always wanted to do, tick that off.
My test hole worked but was a disaster getting it to work, I was wobbling all over the place so I got thinking.....
For the actual hole I put the cutting bit in the drill press then lined everything up and pulled down as if drilling a hole. I then turned the chuck with the key to slowly cut the thread, not what its intended for but wow did it work. The entire hole was done in about the same time it took to do a 3mm test piece wobbling all over the place.
A strange thing I noticed, whats up with the threads, in the attached pic the red highlighted rod threader doesn't match the bolt, yet the green highlighted hole threader does match. Both are a M10 1.5pitch thread, is my external one dodgy and perhaps needs some work? cheap ebay kit is probably why.
Also attached is a mockup of the pier, just gotta screw on the head and bolt it all together, seal it then chuck it in the ground.
Exciting stuff!
