**I’ve Enjoyed Working on A Lot of Interesting Projects …**

### LOOK at LIST on SIDE for Projects ⇒ ⇒ ⇒

### WHY I CREATED THIS SITE …

On this website, I will share photos & CAD Photo-Realistic Renderings of my current projects, as-well-as **Future Concept** ideas … Some projects below water ~ Most above … There will be lots of experimenting … Results, etc.

Unfortunately there are many items I can’t show due to their proprietary nature

… However, will try to share as many of the ‘**Just-for-Fun**‘ projects as I can.

Note ~ I had to remove my ‘Area 51’ joke from this website because I got a few comments from people that because live in Las Vegas … *sigh* … Some individuals actually believe I work out in the ‘Area’… *LOL* … maybe? 😉

With that said, the purpose of this blog is to help me organize thoughts and to remember concepts at a later date, and also to log the dates of concept design ideas. This blog is not secret; therefore, if you happen to find it and wish to read the blog, please ENJOY!!

Sometimes help others with their Projects like these R/C Micro-Rock Crawlers

### Casting Metal with 3D-Printed Patterns

… also create random posts of SolidWorks CAD Photo-Realistic Renderings …

This 670cc V-Twin engine has the correct dimensions & weight ( and center of gravity ) for use in SolidWorks Assembly projects …

… also post whatever else seems interesting on a particular day … or night …

Silk-Scree Unit whereby every part will fit into several Flat-Rate *unlimited weight* USPS shipping boxes which saved over a $100 in shipping expense because weight of parts was no longer an issue …

… High-Res SolidWorks CAD Drawings of projects … ( Click and Zoom-in )

Design Plans can be Viewed & Downloaded from GrabCAD.com

https://grabcad.com/library/gantry-lift-table-complete-plans-1

I try to show building images and * Finished Project* photos to compare with the SolidWorks CAD Design drawings to show how accurate the design process can be from Start to Finish …

SolidWorks Photo-Realistic CAD Renderings help visualize what an item will look like when finished … Even down to the Paint Colors and Product Labels …

I also enjoy to collaborate with other on 3D-Printing & Metal Projects …

My goal is to provide fabricators with more information about 3D-Printing.

After each project I try to write an post with CAD renderings of the design process and also images of the finished 3D-Printed parts.

Example: **3D Printed BBQ Door Hinges**

Please feel free to contact me in the COMMENTS area …

I design a lot of Flat-Patterns for people that with to have bent metal parts …

SolidWorks allows me to dial in the perfect bend deductions & allowances so finished parts come out to the correct dimensions when they are bent in a press brake.

Fit-Ups can be tested in SOLIDWORKS before any parts are cut saving $ …

If you want to Learn more about Electronics and Arduino Micro-Controllers

Watch **Paul’s Tutorials** on YouTube … They are GREAT!!

Paul has a Link where you can buy a very inexpensive Kit allowing you to use the exact items he uses in the Tutorials … I ended up buying an additional kit along with the one from Paul to have extra parts to expand on the Tutorials because the Kits are much easier than trying to find/buy individual electronic parts.

Thank You Miss Brenda for the Photo of the Bighorn sheep for Silk-Screen!

I don’t sleep much, so if going to work long hours at night on SolidWorks CAD drawings, I might as well be comfortable: therefore, created a computer stand/table which allows the monitor to reach over my LazyBoy Chair.

With this setup I can easily see the computer screen & TV at the same time and work for long hours on CAD model design without getting sore.

nice work!

Just found you’re blog. Bravo!

I especially enjoy seeing the balance of “design first then fab” vs “fab and figure it out”. You’ve been bookmarked

I’m looking for some interesting projects and makers to feature on maker2maker.com, please check us out and drop us an email via the site if you would be interested 🙂

I will take a look at maker2maker.com 🙂 Thank You … If you would like to see more CAD files and renderings please take a look at My Profile on GrabCAD : http://grabcad.com/charles.metaldesigner/projects ~ CHEERS

Dear Sir/Madam

The Design and Technology Association is developing a resource for UK secondary D&T students on Systems & Control, including the uses and options available, and would like to feature an image from your website in a PowerPoint presentation for students.

We would appreciate it if you are able to allow the image’s use. We will of course acknowledge the source with a weblink? The link is to https://ctmprojectsblog.wordpress.com/2013/07/page/2/

Would you please let me know if this is acceptable.

The D&T Association is an educational charity that promotes design and technology and provides teaching resources for its members and others.

I look forward to hearing from you. Please contact us at info@data.org.uk

Kind Regards

Jacqui Eborall

You may use any of the images you wish from my website. CHEERS!!!

Interesting Charles! I appreciate your help. The world needs more people like you =)

Keeps me up-to-date with SolidWorks CAD Software features when I am spending a lot of time in the Workshop… Gives me a reason to come in early and work on some CAD designs for people to help them express their 3D-Printing ideas. Within just a few more years, much of manufacturing will be done with some form of Additives manufacturing … Metals, Concrete, Plastics, etc… and I feel most engineers and designers should start familiarizing themselves now with some form of 3D-Printing to prepare for the future. Thank You for the Note. CHEERS!!

Awesome blog! Found it while looking at my RC crawler wondering if 3D printed parts would be strong enough, knew someone had to have done it. Thinking SLS nylon may be strong enough for a 1/10 scale crawler frame, might have to try it out. What program do you use for your renders? I am fortunate enough to be proficient in Solidworks but unfortunately am not as good at metal fab as you are so most of my designs remain on the computer. And am yet to learn proper rendering and tend to just use the Solidworks renderer with pre made materials which doesn’t come out great.

Also love the iPhone submarine!

Cheers.

Sorry it took so long to respond I have been busy building Metal items. I use SolidWorks PhotoView-360 to Create the Renderings and .GIFs … Jim Frye is selling these 3D-Printed Crawler chassis online and he has re-designed the crawler even better using his knowledge of Micro-Crawlers and Robotics. One night when I could not sleep I took some 2D-Drawings of Jim’s and came up with the 3D SolidWorks Concept model for the R1-Crawler that is now called the GOAT. I am not sure the web address for Jim’s sales but if you find it let me know. CHEERS!!!

any more info on the go pro sub? I’d like to explore the idea of using one to study underwater behavior of dolphins.

Hello Sir I want your “small workshop lift table” design part and its report for my study purpose. Kindly send me that report as soon as possible

The SolidWorks CAD files can be found at: https://grabcad.com/library/diy-workshop-table-lift 🙂

Very interesting blog about your powder coating ‘box’. Maybe I have not seen the relevant page on your blog – but I was wondering what spec your computer is for running SW ?

I use a custom workstation built for me by BOXX Technologies out of Austin, Texas, USA it is 4 year old and still faster than anything I could buy in a store … It wasn’t much more than a normal store computer; however, they add the exact items needed to run SolidWorks CAD Software & Photo-Realistic Rendering : http://www.boxx.com/solutions/manufacturing-product-design/solidworks 🙂

Hello,

looking to build a silk screen print. Noticed your post. Do you have any detailed plans?

Thank you

I did it a while back but I can check so see if I have the plans on a back-up computer drive … Let me know if you are still interested, just noticed you note today a month later 🙂

Hey! I’m Brook, CEO of Printrbot. You obviously have skills. I love the little rendering of the sub thing 😉 and the micro rock crawler. Always wanted to do an open source 3d printed one. what do you do for a living? Do you release any open source projects? I’m always looking to promote pet projects from the 3d printing community at large.

All my best,

Brook

Hello Brook 🙂 I sent you an email from SpiderMarlinDesign 🙂 CHEERS!!

Would you create another set of aluminum handles for drill press and sell? I have looked around and think I have run into similar issues of finding a replacement that will last. Mine are a 3/8″-16 thread and will need three.

Thanks!

Next time I do some casting I will make up some more handles 🙂
