Ed Bray said:Okay,
Domishims measure
3/4" Domishim measures 5.9mm
1/2" Domishim measures 9.15mm
In use, both require the fence to be set at 15mm to work correctly.
Hope this helps, Eddie.
Great - many thanks!
So...
3/4" = 19.05mm => center line at 9.525mm. 15mm fence shimmed by 5.90mm is 9.10mm
1/2" = 12.70mm => center line at 6.350mm. 15mm fence shimmed by 9.15mm is 5.85mm
I guess that means the nominal 3/4" material needs to be 9.10mm * 2 = 18.2mm thick, and 1/2" is 5.85 * 2 = 11.7mm
I'll have to check what I've got the garage to see if that's right (assuming my dodgy maths, and understanding of a tool I haven't used yet, are accurate).
