Remember this hack job?

I need another. 

And I’m curious about wax thread & leather. Just may go to Joane’s, the sewing store, to see about options. Options for home-made footwear. It should be fairly simple to fashion a pair of moccasins to run with. I thought about it when I put a welding glove on my foot yesterday. No need for the 5-fingers nonsense, though it is somewhat appealing. 

Have wondered over t-shirts duct taped snug to the foot/ankle, but leather sounds even better. 

And what better to do than work through a problem on my day off??!!

Vacuum idea

Toying with the air hose after filling with my tire, I sit in the car and dust the surfaces. Often, the dust is too thickened or too stuck to the plastic and nothing much happens. I blew all the FOD from my change pile; crumbs flying everywhere. 

This air machine gives a bunch for 75 cents. 

I turned the tip towards the carpet and the pressure blew a clear path of sand out from the carpet. The 1/8″ path of air had bulldozed a full square inch in seconds, leaving pretty blue carpet. 

…yet the debri was only blown inches away. The air ran out. 

Then two days later, I needed air again. I quickly went for carpet after the tire. I managed to sweep a patch of six by six inches. Fairly quickly. I did realize in process that if a vacuum was added to the region, then the dust could be collected. 

A brushless vacuum is basically the idea. Using air pressure. I’d imagine this gas already been applied to vacuums  — I wonder how well it works. Strap say five to twenty of the high pressure air nozzles with a broad stroke vacuum. Air knocks things into the air, vacuum is the large net. 

I wish my car was prepared for a sketch. Perhaps later. 

Engineering questions regarding juice press manufacture

I want to create a simple hydraulic press (up to 10,000 lbs) for juicing. 

A is the pan of a thousand tiny holes. B is the plunger. (NOT to scale)

Both A & B could be made in any way, but if I were to CNC the pieces from a metal — what all needs to be done to it afterwards?

 And what options do I really have?

I’ve always seen “food grade” stainless steel, but is that a designation when buying material or the processes which treats the metal during manufacture?

My initial questions:

  • If I were to manage to get our machinist where I work to CNC the surfaces on which food is in contact, (besides standard soap & water), how do you wash to remove all oils & such that had contaminated the metal?
  • Is there an actual “food grade” metal that should be used?

Other questions are as such:

  • Is there process that needs to be done to harden for pressure?
  • How thick to resist pressure?
  • How thick to resist pressure & fatigue long term?
  • If I used pipe (welded to) plate for a plunger assembly, are the same processes applicable for cleaning?
  • What is the preferred grade of cress to use for the application? Or would alluminum suffice for the project?

The design is very basic. Mash the pulp of fruits/veggies, which is held in a mesh pouch, by a plunger. This slowly forces juice through the drain holes with 5 tons (max) of pressure. 

The press needs a gearbox possibly to slow the speed of the press. As you don’t want to release the juice quickly. 

… 

Thanks in advance to the engineer who I’m asking this to!!

[edit]

The response: 

“You would probably want 18-8 or 18-10 stainless.”

I will query him again, after I do my own research and/or ask another guy.

Gundam 

I’m attempting to model some Gundam dude. I have a picture for reference. I’m not creating a duplicate, but a near copy. 

…here so far, creating a piece every day or two. And each piece will likely be further editing, copied, & revised eventually. It will be a slow process.


Yes, using CATIA at work, but fully off the clock.

A couple days ago, I 3D-printed what I have so far. It’s not much more than above. My attention has been focused on other things lately. 

Not really sure what scale it ended up at. I was using near 2 cubic inches of material. I believe, 1.84 is where it landed for volume of plastic. 

  • Material: PC polycarbonate 
  • At full scale, the thicknesses of those materials would range from 0.080 – 0.20. Ultimately, it is a human sized model. 
  • However. I believe the idea of GUNDAM is that these robots are actually huge. Like 6 stories tall. But I dunno or fully care as of yet. 



Comment to blog post while searching “CAD Workstation for rent”

Www link

Stumbled upon this while looking for a CATIA workstation rental. After reading half, I realize this is a fashion blog and I am an engineer!! As such, I design within the aerospace field, but sadly cannot quite afford a $50,000 per year cost for a lisence (plus a $3,000 cpu to properly run it). 

However, I could afford to rent a cpu and a few hours per month of use on the shareable lisence. There are many specialty workbenches available that I’m sure cost a fortune to buy. As occasionally the hundreds of engineers within our network (at both Gulfstream & B/E aerospace jobsites), we use ALL available lisences and must ask for others to drop theirs. 
With that said, within engineering, you could offer CATIA (aerospace), AutoDesk – original CAD: Inventor for mechanical, Revit for architectural (they actually have rental software now), SolidWorks is huge in many industries, Unigraphics is dying, & other industry specific cadd software. 
For people like me with thousands of ideas that come and go and get sketched on paper. Well that’s great and all, but ink in on paper only illustrates so much. I want to look at it and add details and build onto my one sketch. 
For the idea, preferably I’d like a “school” to go to. Where I use a workstation with high end monitors and have a chance to meet other like minded folks to exchange ideas and perhaps even business ideas. But school sucks; they charge fees for things in which I care not and force you to take multiple classes… I want one class: drafting/engineering. 
Even though I cannot relate to the group of pattern-makers specifically, the idea is great to me. But given the fact that my perspective disagrees with most, I have serious pessimism towards the idea for a productive investment (of $$). If you are able to find a few individuals to begin with and can finance, I would go for it. 
The best ideas have ALWAYS been doubted by society.
