Cucumber - small or no fruit

Thanks JWK, I found a male flower & hand pollinated two female flowers, I had to judge by looking in the centre because the stems weren't entirely straight - there is a little green bit on the end which the flower comes out of I have two plants together would it be okay to polinate female flowers from one with males from the other? Probably a stupid question but I just want to make sure.

 

"I have two plants together would it be okay to polinate female flowers from one with males from the other?"

Absolutely (assuming they are the same variety - even if not probably OK, but might "have issues")
