Default PC 690 - Diameter of Guide Rods?

Could someone tell me the diameter of the Guide Rods used for the edge guide on a PC 690? I want to order some longer rods, than what comes with the edge guide, to build a circle cutting jig. And no, I don't have an edge guide to use as a reference. I've measured the mounting hole and I thought it was going to be 3/8" but it appears to be significantly larger than that.

Thanks in advance,
Dave.

5/16''

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

But, but, but...David said it appeared to be LARGER than 3/8". (3/8"+)
For our metric friends, 3/8" is the the same as 6/16". Stick measured his at 5/16"...somebody's mistaken.

In a recent thread, I had occasion to measure my old Craftsman guide rods at 1/4" ...ie 4/16". I didn't actually measure my Bosch guide rods but they're massive by comparison.

plan ''A''...
insert rod into hole gauge...
read number next to hole...
type in the answer....

plan ''B''...
Have David insert a drill bit that fits the hole...
read size on drill bit to learn the size of the hole...

anything else I can do for ya Dan...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

just so ya know...
the hole size is 13/32'' or 26/64 in metric...

suspect the guide is for more than just the 690...
in metric - that would be ''one size fits all''...

Bosch has two sized rods depending on year and model...
3/8'' (6/16 metric) and 7/16'' (21/48 metric)...
older than dirt Bosch had 1/2'' rods (50/100 metric)...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

You beat me to it...I went out and measured my Bosch rods.... .373" (3/8" or 6/16")
They'd probably fit David's PC.

Don't know what size but there is a Type 1 and a Type 2 PC 690 so that will probably make a difference. Do you have a caliper?
