Working on a new 4 1/2 inch worm mold and need some input

Recommended Posts

I'm working on a new 4 1/2 inch worm mold that I will be machining and offering for sale on our site and wanted to get some input on suggested changes. ( see attached drawing screen shot )

The diameter of the worm body will be just a tad over 1/4" ( .28" to be exact )

In this mold I'm going to include a second port for making just the tail sections. ( good idea.... or bad? )

Thanks for any input or suggested changes....

Thanks,

Kent

The tail and worm body look like they need a better connection point.  A butt joint isn't a great connection, and the tail may fall off during normal use.  Something protruding from the tail that the worm body can wrap around to create a mechanical connection would be much better.  Otherwise, the worm looks good.

Thanks guys...

Yes, I agree Comrad on that tail connection point.... I'll do some work on that..   The outside diameter of each ring is .28"

So maybe 2 or 3 rings on the tail connection that are in the .18" OD which should allow enough material to wrap around it.. 

Is this kind of what you had in mind?  ( see pic below )

Thanks for your feedback...

This mold does have a lot of tight corners which results in a lot of machining time. This mold takes about 2 1/2 hours to machine and it takes 18 separate end mill tools.. so its kind of a spending process.

You asked about the CNC mill I'm using. For this mold I'm using a Haas DM-2 with a 15,000 RPM spindle motor. The machine weights around 5,000 LB

I've been really happy with the machine.

'When did TU become an advertising forum? I thought this forum was about DIY bait making. Years ago posters were banned for advertising here. I visit to learn and share info, not to see an advertisement about a companies attempt at selling an unwanted product to me. '

I reported this post when it first appeared, and again when it dropped the  ruse and went into full sales mode. I know the mods are usually on top of dross like this, but this one seems to have slipped through.

LSM joined 2 years ago, so it is a safe assumption that they know the rules and just decided to flaunt them!

Hi Guys,

When I started designing molds several years ago I use to design them with what I thought they should look like, and I quickly found out that it's best to ask the people that actually use them. otherwise I found myself spending all that time on design only to later make a bunch of changes to the mold that should have been there from the start.

That was my intentions here. The great suggestion that Comrad made for the tail connection got implemented into the final design.

I probably should not have put the link in the post, but I wanted to avoid going through the whole process of folks direct messaging me because I don't keep up on checking these as often as I should.

I attempted to edit the post on Sunday to remove the link, but it won't let me remove the link, so I deleted that section of the post and the pictures of the finished mold.

Thanks,

Kent

5 cavity worm mold plus a 10 cavity tail mold... the price seems competitive to me.

I agree!

Look at the Bloodline swimbait mold a 2 cavity with included bloodline is more expensive. As is the 10 cavity Ice Preybait with included tail mold. I know as I own both of those.

Both from different manufacturers and both at a higher price point. Yet cheaper than 2 molds sold separately.
