Just want the measures for the locations?
Just want the measures for the locations?
Sorry, could not find the thread again.
The rails attach via carriage bolts and t-nut washers so there is infinite lateral adjust ability. I assume that you are asking about vertical location. Measuring the holes, they were 1 1/8" on center below the table top. with teh bolts, there is some vertical adjust ability also- maybe 3/16". There is a slight chance I have the guide around- I will look for it tonight.
I found the drill guide. The center of the hole is 1" from the table top. The hole size is 3/8". Bolts are 5/16". . . . . The second quirk is the micro dimples that the locking mechanism puts in the "hardened" steel guide rails. After a few years it will be difficult to get an exact setting (in the heavily used area of the fence) when clamping down. The solution is to swap the front and back steel guide bars, to put the dimpled area in a different place.
Doing some organizing in my loose item container, found the excalibur drill guide if still wanted.
I have a baltic birch extension table covered with Formica and it works well- I don't get any significant expansion but it is the basement that runs a dehumidifier constantly during the summer so (I hope) the humidity does not greatly vary through the year.
