i just finished coating around 200 baits with devcon. Dont worry about the bubbles while mixing. If you have bubbles while applying i think your putting it on too thick. If you go too thick with a coat it will also cause a little yellowing. Just keep at it. Once you get the feel for it they will turn out great.

Where do you get the stick on scales?

Yeah tried that. I am using a rebel xti

Here are a few i just finished. Any pointers on taking pictures. These are in a light box, just cant get it to focus just right.

Here is another go at it. Need to add a little venting to this one.

Thanks Bob. How small does the vent need to be?

I should note these are bill tied, so tying directly to the bait would change things and you could go to a lot steeper angle.

Well i have tested 22 baits since i asked the question. Like others said i am sure it will be different for every bait, but 6 degrees to 21 seems to be the sweet spot. All the ones in that range run really good. None less thas 6 would run at all and it was hit or miss about 21 to 26. I am using a cnc machine so this angle is dead on.

Here is my first go at it. These are two piece hand poured. Ive never seen a commercial mold, but these seem to be working pretty well.

Thanks Bob!

What angle would you start with? 2.5" cedar bait.

Well, sealing with epoxy seems to work good. The plastic will just fall out. Now to just get the designs cad. Bob you have any paticular brand of bits you would recommend for aluminum?

Looks like it time for me to upgrade my machine. So how much you think a 5 axis machine will run?

Thanks Bob! Yeah my estimates on cut times for aluminum are way too long. Maching the pvc is easy thats why i asked in the first place. Well it turns out the pvc is not affected by the heat at all. I even burned a few batches and the pvc held up fine. Now with no sealer or release agent the plastic stuck to the pvc. It would come off so it did not bond just not very practical. Just spraying it with pam worked pretty good. Little sticking in edges.My last attempt i put a lure/jig sealer on it, let it dry for about 30 minutes and sprayed with pam. I turned it upside down and the plastic fell out. I have an injector on the way does anyone have a closeup of how a two piece injected mold is set up.

I guess ill just melt some tonight and find out

He replied "They are high temperature resistant plastic (PVC). Thank you for your question"

One of his sure looks like pvc.

The frame is pvc (zen cnc) spindel runs around 28,000. 1/8 or 1/4 bits. What bit would you recommend and what kind of feed/depth rates?

I have a cnc that can machine pvc but not aluminum. Would pvc hold up to the heat? If not what plastic are the commerical molds made from? Thanks
