I used inventor to design my bait. Although I am only using this as a template at the moment. I am in the process of trying to figure out a simple fixturing process to machine these from blanks. As of now I am leaning towards a two operation process, one for each side. Then I would manually remove the ends. I have seen a few duplicating machines on youtube that have the fixturing down pretty good.
I have put this project on hold as I debate on just switching my materials from wood to foam.

Heres a couple new projects, I'll post the prototype images soon. That swimbait is enormous, now I have to go buy gear to throw it! Ohio bass havent even seen blugill lures to this scale so a reaction strike might be an understatment haha

Cool! I just got a student version of inventor the other day. I'm sure it will take a lot of work to get comfortable with the program, but I'm liking it so far.

A-Mac thats great! Have fun with it! If I see enough of a demand for CAD modeling practice help Im thinking about doing a tutorial on model feature organization/design intent.
Not sure how much experience you have with CAD programs but I'm always willing to help!
Its one thing to build a model that looks the way you want it to, but its a completly different story to build that model with the robustness required when you start tweaking dimensions and dont want to go back and rebuild half the model. I use these platforms for a living and I'm still learning these techniques so its not an overnight deal, but for me it beats carving a model by hand(even though I hail to the guys on here that do).
One cool feature you should check out is to import a JPEG of a crawdad, shad, bluegill, etc. and use that image as an underlay to create your sketches for buidling the surface model. Takes a little bit of the artistry learning curve out of it, because its all about the ratios between the physical features of the animal to make it look "real".

Would love to learn more about this if you did a tutorial about lures. They are very distinct shapes and attributes. I have been mucking around with 3d stuff for several years now. Dave is a master of this stuff. Was a huge help in getting my feet wet. It's very time consuming.

Here is a selection of some of my models. I have not included any of the sold models as that would not be fair to the customers. All models drawn using CATIA V5.
I have left the surface joint lines on the first two, so that you can see the basic construction plan. Sometimes I use circles but the best results come with splines. The hardest parts to model are the nose and tail. I use a lateral line to shift the buoyancy up higher.
The second was a swimbait idea. I decided that it looked too lumpy and so never built it. The CAD model allows you to see a realistic image without leaving your seat.
The craw was modeled just for my own interest, to see if it was possible and how long it would take. I had a buyer interested, but he was not prepared to pay for the time. Even though it was already drawn, I would not give it away for peanuts.
The fourth image of the Bawal is a recent project, to design a quick and easy to build lure. Build and assembly time is less than 30 minutes. A great hunter and it catches fish, one of the few lures I have actually fished.
The green swimbait was an early design, to test the effect of joint directions. Result – the joint needs to be reversed. Cad was very useful for planning out the hardware layout.

Dave - Thats some awesome stuff! You mention that you have customers, do you do this on a consultant level or do you manufacture/sell your baits? I'm beginning to get to a point where I could see selling my baits once I get them tweaked and tested (<1 year), and seems like youve gone through alot of the obstacles I'm about to come upon. If it would be ok, I'd like to PM you and ask you a few questions. Once again, these are some great looking baits!
Since it seems like CAD isnt the dominant means of prototpying lures on here, lets mix it up alittle bit.
Does anyone have any pictures of their full line of lures(CAD or Physical image)? Example: Shallow Crank, Deep Crank, Topwater, Craw , Frog, Lipless crank, and so on?
I thought this would be interesting to see since this is the approach I'm taking right now, trying to fill out a "line" of products. Just a thought to give everyone a place to showcase their Brand!

Ohio angler - PM is fine. Maybe you should start a new thread for the other questions, as the subject is moving away from the original.

Thank god I am not smart enough to understand this Dave, I would need 36 hours in a day.
Nice 'drawings' all. I wish--I wish.

Just got around to printing the swimbait from my previous post, and now I am tweaking the ballast location and line tie location to get it to swim correctly. Almost there! Now I need to find someone to do some paint jobs!
PS- Can I upload videos to my post? I have a .mov file of this bait swimming as well I just didnt know how to upload it.
Posted 02 July 2013 - 03:43 PM
That looks awesome! So that was done with a 3d printer? How long does it take it to make? I'd be very interested in seeing a video. Is it a buoyant material, or is it hollow?

I have spent some time thinking about this as I already have a modestly small CNC router that burns through wood like a princess goes through her daddy's credit cards. It was not expensive, but I upgraded it to make it the wood shredder it is today. I bought one of the little Chinese import CNC routers pitched the rotary tool it used for a spindle, and installed an actual wood router on it as a spindle. I alos upgrade the stepper motors and controller. Add a computer and control software and its about 2 grand in it not counting my time.
I could rough out crank bait bodies a couple dozen at a time. pretty darn fast. For me the hold up on doing more along that line is the paint process. A good job on paint is time consuming and stretches out over days.
A simple 3 axis CNC router like mine could produce a lot of bodies. A plastic body machine like the Fireball could do it, but slower because of frame flex. This pieces is about 10 inches by 6 inches I think. Complete machine time is about 30 minutes including cutter changes for the small stuff, and this is a HARD wood. Red mohogany I believe. Its probably the equivelant cutting of roughing out 20 small crank bodies.
If I took it as a challenge I am quite sure I could build a machine for my own use for $1400 dollars that would produce similar results. Don't count the computer and the control software and I would bet money on it. I would not however build and sell a machine for that amount of money. My time is worth something too.

I would add that for some simple bodies like flatside baits that don't have anything more than a roundover on the top and bottom I could cut them out an order of magnittude faster. The machine would probably cut them faster than I could setup the next sheet to cut.
P.S. Don't be tempted by the Carvewright. It has kind of a cult following, but it only "looks" cool. There are lots of more crude looking machines that would smoke it without breaking a sweat and not spit ball bearings all over the place doing it. Read some of the old reviews on it.

P.P.S. I have worked with Dave a couple times, and his stuff never has stupid beginner issues with the graphic files. Its been spot on.

Surface finish is always an issue, but if you could rough a body to ready to sand in minutes per body wouldn't you? (There are thing you might be able to do to improve that too.)
And, no. Doing just one side is not the limitation. I already solved this problem a long time ago. Setup a simple clamping jig with alignment pins along a central axis. Cut one side, flip the piece, reverse the scale, and cut the other side. One piece wood crank bait bodies by the full sheet. Cut the holding tabs and sand. Thiockness isn't even an issue if you zero to something other than the surface of the wood sheet.
I have done it for certain types of features with molds too like fins that stick out the sides of a bait. I have to machine both sides of a top (or middle) plate, so the first thing I do is machine the bottom plate with alignment pin holes along my flip axis. Then I drill or mill matching holes in the plate that goes on top of it. I mill the top of that plate, and then I flip it over and mill the bottom.
I'm not picking on you though. I am almost embarrsed by how long it took me to figure out somethingthat no seems so simple.

So, 3d printers typically print in abs plastic with many colors to choose from. At work, I use the printers for prototyping mechanisms and form factor models when we need it quickly. It also prototypes fishing lures quite well. There are a couple problems with it though. I print the parts as I'd they were to be injection molded parts and glue the two halves together. Inherently this is hollow. But! I have to seal the model to make it watertight. This is done by dipping the model in acetone using a process I have developed here at work. When I generate the cad file I can place the lead ballast weight in the part apply material properties and immediately tell where my center of buoyancy and center of gravity are. Then if moving these critical points is necessary I can do so methodically with in a couple minutes plus about 2 hours to print the updated prototype. Really cool technology and I think as it becomes more affordable lure designers will have them in their homes, I know I will!

ABS 3D printers are already out there on the hobby level. Most are struggling at the "look what I can do" stage, but some are producing some astounding results. I don't think its at the "buy a tool just to be supplemental to another hobby" stage like subtractive machining just yet though.
