Thanks for the heads up Petey...

After being informed about this item, I would have received mine in about 1 months time... IF they shipped to Aussieland.

It seems a TAD (big tad) better than what I've customised,

Unfortunately mine is more a macro adjustment rather than a micro... The 6 TPI thread may not be optimum.  Unfortunately I have to use 4 mag switches as there is too much play in my fence between firm and loose hold, and I have to have it on firm to ensure it locks on 90° with the last press... so it needs to be virtually locked as I advance it... I'm guessing a lot of that is due to the sheer weight of the fence brought about my on-board acoutrements.

At least this has inspired me to start looking at a metal threaded system... Difficulty will be attaching the "swivel" to the fence. 

If your first cut is too short... Take the second cut from the longer end... LBD
