Looks like very nice attention to detail.
Use it a couple weeks and you will find with large rounds that the top two splits will fall on the ground, one to each side. Or they will end up on the out feed table behind the wedge. That is how the Delta wedges work. Or rather, they work you. It's a poor design, copied over and over.
When you get tired of walking around your new splitter chasing splits and lifting them off the ground, weld an extension on the four way and make it a shelf extending rearwards of the main wedge, like the top of a box wedge. The difference from a box wedge being your single wedge sticks up above the self, creating two pieces on top. They should sit there, within reach with a pulp hook. Pull one to the log lift and one to the beam to re-split. Rather than quartering big splits, run the wing low, then raise if those lower two splits need to be pulled back to re-split, while the two large splits sit on top waiting for their turn. If the lower splits are a good size, push them through with the next cycle.
Below: Timberwolf's TW-6 with a terrible wedge design. Fat main wedge and Delta four-way.
Modified wedge. Extension could have been wider due to fat wedge design pushing splits sideways a lot.
Standing between the hydraulic tank and log lift, the lower split can be easily pulled back with pulp hook by raising four-way to untrap it. Then re-split, leaving the top two pieces nest on top of four-way. Next lower four-way, pull near piece to log lift, and far pieces beam.
If your just making big boiler wood then a delta wing is fine.
