CAD model for front/rear bumper mounts, open source maybe?

I've looked a lot for diagrams/schematics for tacoma front/rear bumpers. Ive seen 1 or 2 DIY kits, but no schematics.
Here's the thing.
I'm good at CAD. I'm good at design. I'm good at Solidworks and Solidworks:sheet metal extension. I have access to build bumpers myself but I don't have any interest in doing that as a career.

What I need to do this is have a good, ideally CAD model of the proper mounting points on the tacoma for this model. Distances and locations and angles of those mounts. I imagine most of the ones built are done off of measurements of the truck actual and not off of a CAD model, but I'm thinking *maybe* somewhere out there is a cad model of the truck frame.

If I could get this I would build the model and make it open source or take donations for the schematics/ paper diagrams. For, you know, the community, or whatever.

 

Once you get the mounting locations you still need to make sure that the top plate will fit. That takes trial and error with cardboard. Hard to take an overall dimension for that. Same with fitting a winch under the bumper.
I haven't released my bumper yet because someone will end up doing it for money. It's actually all in SW.

I wouldn't mind writing out the mounting locations. That's also up to interpretation on how you want to mount it although there's not 1000 ways.

I figure if I put it out under CC and then someone builds it and sells it, they're selling their labor and material cost. The margins are pretty slim on that; VS if I sell CAD model or paper models for say, $50, that's way less back breaking labor for me, as much as I like welding.

 

So are you going to have it as an open source or are you selling the models.
Not sure someone would want to give out the time it took for them to do the work of making sure the bumper fits for someone else to sell their model haha.

 

Open source model, sell paper plans. In my experience people are too lazy to find a large format printer and print something out when they can buy paper plans for $50 or something.

 

I've been looking for a suitable first gen CAD model to mock up a rear bumper, but haven't had any luck. Mostly pre-Tacomas out there.

 

Have you tried making a mock up?
Rear is easy compared to front. Take off old bumper and take the frame measurement for mounting.

 

The rear bumper mounting on the second gen threw me for a loop the first rear bumper I fabricated! It's not complicated but the little details are ....tricksy.

 

I won't be ready to build for a while, still need to learn to weld and buy equipment etc. But I'll have a garage space to work in starting in March so that might happen at some point.

Really just want the CAD model to tide me over till then

 

Have you ever thought about using a Laser scanner? You can rent them for a couple hundred dollars. You would have decent tolerance results (1-3mm) And you can have models of any truck you please. I use 3d point cloud drawings at work, to create detailed large scale 3D models of production plants. In my opinion, its the most efficient tool for retrofitting.

 

Not a CAD but 1st get frame measurements. Hope this helps some.

 

The flatland kit I bought was close but not spot on. I had to extend the mounting holes on the side rails about 1/4" to get it to fit right. The real pain in the rear were the large bolts that go into the end of the frame. Lots of elongation there to get it to sit with all of the distances to be the same. I ended up welding a chain on it so that I could use the engine hoist to put it on, take it off, elongate, repeat. No way in hell one man could put the bumper up empty... and the winch and forget it.

 

There you go, buy the flatland kit and make whatever you want @mermalady

You might have had it move when you welded it all @Glamisman

 

I have stuff for the back.
Do you own cad software though?

 

3D scanners can be great, but not for all applications. For one, they don't like black/dark colored objects. You'd have to paint/color anything dark. Point cloud data (faceted models) aren't very fun to work with either if you don't know what you are doing. All that said, it may be worth a try. I would also recommend 3D printing important interfaces to check you design. My 2 cents.

 

cardboard aided designs the way to go.

 

I'm pretty sure that's not a first gen frame. The file is even called 85 frame...

This is the diagram for an extended cab frame. It's still not really enough info to work from.

 

I found a frame model of what looks to be a 2015. however, It's not free.

Have access to Solidworks through work.

This is exactly my plan.

 

Not to kick a dead horse here but how are we doing on this front? I'm yea close *pinches a cunthair width of air* to surveying the bumpers plan view and then section/details of bumper mounts. Just waiting on snow to melt.
