Before I started the last frame I cut, I created some simple saw horses out of 1x6 pine boards for using to hold timbers while using my chain mortiser.
The height of these saw horses, which we called ponies as they are so short, is 18".
I can't see how to attach a pdf of the plan here on this forum, but if anyone would like it I can email it to you. Just let me know.
And I can't seem to see a picture of them in my folders, but they worked for me by lowering the timber to a position where you could stand over the mortiser and line everything up.
