Thanks for the feedback GW... Furtunately all my cuts were withing the capabilities of my mitre saw's "height"... I can see the benefit of the tenoning jig on the TS for say 290mm wide boards...
Hmm, that's got me thinking that my tracksaw on a piece of timber clamped flush against a "tabletop"/base could also do the trick... length might be an issue though.... never tried but may be worth considering... if you have a tarcksaw.
If your first cut is too short... Take the second cut from the longer end... LBD
