I just spent 2 hours looking for a mold for them and can't come up with anything.  Does anyone know of anyplace that could either make one for me or sells a mold for a 4in soft plastic spider grub/hula grub?  Or do I have to buy the skirts and melt them on seperately?  If a mold for the entire grub isn't available anywhere, is there a way to get a mold for just the skirts??  this is frusterating

I've never seen a mold for the skirt part.  I would expect you would need an injector for something like that.  The only way I know of doing it is pour the body then melt the top on it.

Yeah i think they make the skirt part of that separatley and then attach it to the grub body

What if I made a tube mold...not sure how to explain this but you soft plastic pourer dudes might be able to tell me if this is stupid or not.

1.  Make a mold using 2 different sized dowel rods.  It would have to be a 2 part mold.  The thick dowel rod is for the "tube" and the thinner one would be for the skirt.

2.  Pour the plastic in from the top then insert the smaller dowel rod

3.  Let plastic dry

4.  Pull out the "thick headed tube" and cut the hollow part into the spider grub legs.

Would that work or no?
