Cross dowel, 1/2 Ply, jig ?s

[Redicliff]

I'd like to use cross dowels to join 1/2 ply.
Assume 1/4 is appropriate cd size?

But, the jig?
I find this jig on aliexpress
3 in 1 doweling jig
which looks like a knock-off of an earlier, discontinued Woodpecker's model.
or would an inexpensive jig work, such as this Home Depot offer
jig

Advise and recommendations appreciated.

Don't think I'd use dowels to join ½" ply. There are some good doweling jigs available of that is your thing. What are you planning on joining to what and using what joint style?

This is what I think of as a cross dowel.  Is that what you are talking about?

the first jig you linked to looks to be the type to install cross dowels like Allen shows in his post
the other one looks to be just a doweling jig to install wood dowels
there are a few cross dowel installation kit makers at least there were like jessem / woodpeckers / LV and probably more
