Never heard of trefoils until I saw them on LJ, then immediately had to try to make one. In cherry, with wipe on varnish finish.

Basically copied someone else’s project, except made the segments 3/4” instead of 1” because of the stock I had – though in retrospect the 1” looks better and would be stronger. Not too happy with the result, but lessons learned:

1. Pay attention to wood grain direction! I have most of the splines orientated in the wrong direction, making this very fragile. Doesn’t particularly help when sanding / finishing when you have to be that gentle.

2. If you are going to make a jig, use decent plywood. I had made a little sled to cut 45 degree miters, but made it from cheap plywood which turned out not to be sitting too flat, throwing all the angles off.

Will be giving this another go someday.

I did my learning experience with 3/4” just to convince myself that I could cut that many 45 angles and get close. To my amazement that part worked. I didn’t use splines. No splines meant 3 days of gluing up smaller segments before complete and the last mating of two big segments was high anxiety.

A big learning item was to make sure the wood was the same dimensional square at all points. I must have had some snipe involved with the board I cut up, some intersecting pieces had overlap on two sides of about 1/32”.

Cherry and walnut stock are cut for the next ones, these will have splines with attention to dimensions.

The nice thing is that regardless of how far off you might be, you can always recover by cutting the last 3 segments to fit as each one has a different orientation.
