The insert plate isn't glued up yet, and still has the protective film on it, but you get the idea.
I removed the 8mm threaded rod from the router and took the base off. Removed the spring in the column furthest from the adjuster.
The threaded hole where the 8mm rod was had a hole in dead centre so I used this as a pilot hole to drill a 6.5mm hole for the connector bolt. Also countersunk a little around the hole for the casting under the bolt head.
The connector bolt has an allen key socket in it's head. So before putting it all together, I fixed the base to my insert plate and used a brad point bit, which fitted through the 6.5mm drilled hole, to mark the insert plate where to drill for the allen key, for above table adjustment.
I removed the base from insert plate and drilled a small pilot hole through. Then on the bottom of the insert plate I used a forstner bit to counter-bore a few mm deep for the head of the connector bolt. Then drilled out the pilot hole to make it big enough for the allen key.
I drilled 2 small holes in a tee-nut that I'd removed the spurs from. Then used this as a template to drill 2 small holes in the horseshoe part of the router body. Then 2 self tappers to hold in place.
Threaded rod cut, long enough to go through the tee-nut and meet the connector bolt without whizzing out the tee-nut on the opposite side. Also for 2 nuts as a stop, to stop the base coming off. Then another nut on the lower section of threaded rod.
The two are joined using a rod connector (a long nut). Mine was 18mm long so 9mm on the connector bolt and the other 9 on the rod. I added threadlock to 15mm of both the threaded rod and the connector bolt then screwed them into the rod connector tight against each other. Then brought the two nuts up tight to the rod connector to ensure a good lock. Then it was left for 24 hours to ensure dry.
On the top part of the threaded rod I originally just added two nuts locked together so I could use my cordless screwdriver to move it, but then added a homemade knob so I can turn it myself for micro adjustments. This is why there's an additional rod connector and section of rod at the top. It still has the two nuts for my screwdriver too.
Think that about covers it. Any questions, ask away.
There's a video of it in action here.
