What is the best cut to join the two sections: 1) one straight mitre from corner to corner approx 30 (& 60 degrees) 2) a 45 degree mitre from the inside corner with a right angle portion on the wider board exposing end grain that would then be flush with outside of the narrow board 3) a 45 degree mitre from the outside corner with a right angle portion to the inside corner 4) a butt joint exposing end grain for the full width of either the wider or narrower section.
Are there differences on the stability of the joint. My own impression is that the most attractive and possibly stable joint would be choice 1, a straight mitre.
I have all the machines but cannot cut the full mitre with my sliding compound mitre saw and am concerned that it will be difficult to do it with my table saw (General with a 12" blade and wide table) as the material is very heavy and the angle quite acute. Can this be cut accurately with a portable saw? Any other suggestions.
Also, are there any suggestions for strengthening the joint?
Any thoughts are appreciated and thanks in advance.
