Jet Tags Hull! - Game Changer

[makejetskiinggreatagain]

What about machining it out of plastic? I don't know much about CNC. I've been poking around about building one. I have another product that I would imagine would be easy to machine out of 3/8" plastic sheets.

I think similar complex shaped, small plastic parts are injection molded. Tooling is so expensive though. I just think what I could accomplish if I had a CNC. I don't mind the labor if it means I can save thousands of dollars.

the problem with machining that part isnt the material. Aluminum is already considered soft as butter in the machining world. the problem with machining it is the process called surfacing. basically you take an end mill, usually a ball end mill, and you create a toolpath that involves hundereds of thousands of lines of code and thousands of tool passes. the tool makes a cut and steps over a very small amount, like lets say .001" and then makes another cut. This is used to cut odd shapes. The software to produce surfacing code is usually extremely expensive. Here is one of the coolest surfacing videos out there. They are using a 5 axis machine but surfacing can also be done on a 3 axis with multiple operations and sometime hand work to eliminate blend issues.

Wow that is cool I think I just had a nerdgasm. That machine is on my wish list. Make a slight donation and buy some HIN tags! Just need to sell 50,000 of them and I will be there.

I really need to get up to speed on some of these manufacturing techniques. Maybe I can find a decent book to get started.

I have the software to design molds for plastic injection, but it's useless to me because I don't know the intricate details.

The conversation that happens when the one guy who sells hin tags tells the other guy who sells hin tags to make donations and buy some hin tags.

Haha we are stainless steel to plastic. Like apples to oranges. Wet Dreams definitely wants his logo on his HIN tag

 

[makejetskiinggreatagain]

Haha it's true, apples to oranges. Plus competition makes life fun truthfully I love his tags, especially those ones he did for Nate_D!

That's one of the coolest things I've seen in awhile. I can't imagine the programming time for that.

I'd wear that helmet! Regardless of weight or what people think! Stick some pads in there and go! >

I made some major changes today. I got a finish that is pretty good. I think a lot of people would be happy with it just the way it comes. By making the bottom deck into two separate pieces I was able to make a hollow engine bay. The hood no longer needs to be glued. It has a slight interference fit that it won't fall off, but can be removed. I may introduce a motor later on or it can be used as storage for. I will update photos tomorrow.

Also I may add silver to my collection of colors. I think it would make for a nice contrast on black hulls.

I want one to set on my tool box at work, I should even make a mini lake think of it as a "tech deck"

I am taking it one step further. I will have a photo line up of every color I have by tomorrow. They will be ready to order minus the acrylic stand. The stand will be another week away because I prototyped one and didn't like the angle.

LOL just bustin your balls. Keep up the good work.

I haven't read this whole thread - but I want one!

I just want to know how you were able to pop that intake grate off the build plate using a fused deposition printer

I use PEI surface at 100 degrees C.. I don't really prep often. Printer settings matter a whole lot too (first layer height/width/speed, adjusting bed temperature by layer etc.) I just periodically wipe it down with ABS/acetone mixture. Maybe once a week (when things start warping slightly). A nice sharp knife takes care of removing everything. When I first began 3D printing I figured out very quickly that information on the internet is false and misleading. I think the people who actually make things don't post their methods online so I was left to tuning in my own way. One time the internet had said "220 C for polycarbonate" .. way off the mark .. it's more like 285C and slowing extruder speed in 1/2 in comparison to ABS.
