I have been working in a fiberglass/composites shop for the last 9 months and have access to tons of resin. I've been wanting to get into doing some hand pours of fluke like lures stuff I use a lot. How should I make the mold I've watched videos and I know how to make it but should I just leave the top of the fluke as the spot to pour or should I make a clam type design and bore a hole and then vents and pour into it that way.

That one will be simple to make and pour as an open pour mold. Make the back (top of bait) flat and pour through that.

What about doing worms though I want round

Yes full round you will need a two part mold. If not too fancy and no curly tail you may be able to hand pour it. If not injection is needed.

if you can push a wire thru the worm then you'd be able to suspend it , Fill 1/2 way up the worm ,  Let your material cure then pour the other other 1/2 over top .

at some point in between you may want to add a couple locator pins or something so that your molds close up properly located every time . Its possible that your molds won't be tight enough to need venting , but if you are getting air locks then a hacksaw is a quick venting tool .

a single side pour would do for most  flukes

I you do a 2 sided be sure to put lots of oil on the first half so they won't sick together.

Thanks guys I think I'm just gonna start with a open mold for flukes. I have gallons upon gallons of resin we throw out once mixed so I'm just gonna dump the waste into my mold container to make the mold. Won't cost me a dime to make the mold.
