  1. Last week
  2. Update: 10/15/17

    Going to try to make updates weekly again. Printed a new version of the dimensional control bracket bought parts to put together the bracket and all pieces to mount the rollers and the strain gauge. Then put bracket together wrote down changes that were used to make amendments to dimensional control bracket So as far as my list we are at 4/12 steps.
  3. Update: 10/14/2017

    This week i was finally able to get my feeds and speeds right to finally cut an entire sheet efficiently. This next week will be considered the first week of production for all the parts of the shredder. The feeds and speeds will be tuned further for the machine i am using to finish the full sheet without stopping (efficiency improvement) Hopefully the efficiency gets to a point that an entire shredders parts can be finished in a day (4 hours reservation on machine). Next week i will order more 3/4 inch drive shafts. I forgot to snap photos before i left the shop today so i will do so tomorrow. machining to begin again monday.
  4. Earlier
  5. Update: 10/2/2017

    I have made a list of the things that are left to do. and i have been getting things done in order. image will be posted bellow. I shiped out 1 unit for a backer that wanted his unit early before the modules to play with I reinforced the hell out of the box to ensure that it was going to make it to Germany in one piece. We will see how it fairs. 3 out of the 10 things have been checked off from the list and i now have dedicated days per week to the project now. as i have money coming in from contract work else were. What you will see from number 1 and 2 from the table is that i finished a way of mounting both the expansion modules to the frame and fixed the mounting bracket onto the modules. Then yesterday i got most of the supplies to assemble the modules. these early steps are the easiest and as they go down the list the time required gets more.
  6. Update: 9/22/2017

    Outstanding ! When do you think you will be able to ship some units ?
  7. Update: 9/22/2017

    Massive Update Yesterday i cut out a few shredder dials on the mill As you will see bellow they are perfect. I will be cutting more this coming week and hopefully have enough pieces by friday to make a whole shredder. The pieces are being cut on a tormach. the precision is great. parts are around .0025 in off. (that is about a hair strand) I will post alot of pictures bellow make sure to check them out.
  8. Update: 9/7/2017

    This week I tapped all the couplers mounted all motors to their corresponding brackets with thrust bearings and couplers installed filled down the hard edges of the auger so they are now ready to install. Continued to work on the primary testing machine. more work to come. I am sick this week.
  9. Update: 8/28/2017

    This week i have cut the augers down to appropriate profile. Also i have ordered and recieved the screws that i need to put together the units. Today i plan on tapping all the holes on the couplers for the motors. Hopefully soon finish the unit that someone requested early and get it out. and see how it fairs shipping overseas. Then i will adjust further shipments international accordingly.
  10. Update: 8/19/17

    I finally got in 3 drive shafts. 3 3/4" square shafts of 1045 8" long i also got 2 sets of bearings in for testing a wider ID and a thinner ID one flange set and one non flange I have been investigating a multitude of manufacturing techniques since last update i think i have decided on milling it.(the thought i had since the beginning) i will be going to end mill retailer to get some tips and tricks to start. more coming very soon.
  11. The Green Engineers now has an office of operations in the basement of tech shop it is a 8' x 12' "maker cage" it is where The Green Engineers will be operating out of until upgrading to a larger cage I will now be building stuff and designing stuff out of the cage it was mainly rented to allocate all pieces and tools in one place as well as building production machines for the cage as well as being at tech shop to access their production machines. Added ssd to old laptop and now it will be there permanently also got 2d printer for shipping labels and my Trinus 3D printer Check bellow for pictures of the cage progress
  12. Situated In Office

    i am finally settled in in office. mostly everything is transferred however some things got lost in shuffle so i am repurchasing everything that i could not find i started assembling units. also looking for help from a intern to assemble. soon you will see a picture of them all assembled.
  13. One Week in Shop, And New Blog

    After 1 week of being in shop let me show you guys how much i got done to get it online First i sourced a 6 foot 3 shelve industrial shelve a 8 foot x 30 inch table took everything from my parents place and stored it in the cage put ssd in old laptop and now it will be permanently used in the cage. also bought a lot of tools that will be used at tech shop rather than relying on tech shop to have the tools when i need them check out the pictures bellow generally each picture represents a day of setting up the cage over a week period. so you will be able to see the progress. also i will be starting a general blog called The Green Engineers Official Blog that will cover general stuff like this. check it out for periodic company updates.
  14. Major Update: 7/28/17

    Today i secured The Green Engineers first work space It is the basement(lower floor) of tech shop san jose it is a 8'x12' "maker cage" So finally i can ge the stuff out of my parents place("storage") and into the place that i work on it No more lost tools and parts because someone moved them finally going to have one place to store everything this will speed up all work So now i will begin bringing everything that is involved with The Green Engineers into the "shop" and for the next little while every time that i go to tech shop i will be dropping stuff off and "furnishing it" super excited as this is a big move for The Green Engineers This should bring great efficiency to working on projects in a more timely manner check bellow for images of the currently as of today empty maker cage. Now The Green Engineers HQ. another big update on multistruder coming soon.

  16. 7/27/2017: Update

    Did some more cuts on the plasma i am struggling to get good cuts on it so i think im going to transition to using the water jet till i get the cutting right on the plasma so my expenses per shredder have just gone up drastically. each shredder should cost around 100$ to cut so once i get a prototype built the price for further units is going to jump drastically. im thinking somewhere along the $200 mark initially however it is going to decrease my time in post processing the steel to clean it up also this week i tried to heat treat the steel in a electric kiln at tech shop redwood city i found some issues with heat monitoring and decarbonization because of an oxygen deprived environment inside the kiln. but i bought some hardness testing files to test the rockwell C of the steel post heat treating and they are on there way from japan. also i will probably start designing my own kill to introduce carbon into the compartment to carbonize and prevent decarbonize. check bellow for some awesome images. stay tuned for big update by end of week.
  17. 7/17/2017: Update

    went to cut some more wens day and the cam software running the cutter is ignoring the inner squares on the spacers so need to figure out why it is doing that. but going to be cutting again this weekend.
  18. 7/17/2017: Update

    "going to finish up an entire shredder this coming weekend" Very nice ! Can I have it ?
  19. 7/17/2017: Update

    Got some cutting in this week Got the calibration of the fusion 360 done to get the center square perfect going to finish up an entire shredder this coming weekend i am still shopping for bearing setup and a drive shaft supplier full product coming very soon Check bellow for a lot of pictures.
  20. Update: 7/9/2017

    I have purchased and received the plate of steel. It is beautiful. 1055 1/4 inch steel 4' x 8' However now i need to figure out how to get it out of the back of my truck and into tech shop redwood city. as tech shop redwood city has no grade level door and no forklift from what i believe so it probably needs to be rolled in through front door on dolly. i was trying to go today but for whatever reason they were closed or something i am going to try to go tomorrow Sunday but i have a lot of summer class homework so i will see what is going on. As i am definitely going to talk to them to see what we can do. i also got a 3/4" solid square bar to check my holes to make sure they are correct. i will do the best i can to start cutting asap. Pictures of plate down bellow
  21. Hey guys if you would like me to send your basic unit to you while i finish work on the modules let me know and i can send them out to you asap. then i can send the modules out to you when they are finished. First come first serve. Otherwise hang tight and i will get them both to you at the same time.
  22. Update: 6/29/2017

    Hey guys sorry again for the radio silence. The reason why i have been gone is i have picked up a summer job to get some more funds for my project So here is a deal i am thinking about the fastest way of getting these out to you. This weekend i will be coming up with a solution. What i was thinking was to ship out the base model to you guys. Then shipping out the modules and me just bite the financial bullet of shipping 2 boxes. Also i dont think the entire thing will fit in that box safely. It would probably fit just not safely.
  23. 76th Week: 5/30/2017

    yes posting update right now.
  24. 76th Week: 5/30/2017

    Are you back since 17 days now?
  25. Update: 6/21/2017

    I have finally tried the cut on the shopbot with a 3/32 square endmill 3/8 LOC and 1 1/2 overall long story short i picked wrong parameters and broke the endmill in about 5 seconds. within a cut of half a inch. so we have a few options either i can keep trying to figure out the parameters while paying for 15 dollar endmills every mistake. and supposibly even if you get the parameters right these endmills only last for less than 1 shredder each. or i up the endmill size but that would cause larger radius which would mean loss of detail and material. all of these cause alot of problems So i think i have come to the decision to make the cnc plasma my production machine. Then i will just spend the time to get rid of the taper problems. Most of the taper problems are just the inner square for shaft. so maybe a broach or a router bit i sent another inquiry to the steel company for the sheet. setup delivery locally for pickup. However the sheet for delivery is quite a bit more than i originally thought. I will be doing some summer work helping out starting monday so i will be able to get the sheet soon.
  26. Update: 6/10/2017

    Back home from vacation Going to try something new for first shredder. Tech shop is going to allow me to use the 4'x8' shopbot to try to cut with i have a 3/32" 2 flute end mill We are going to see what kind of quality i can get out of the shop bot as calculators say i can do 35.4 ipm so it wont be too bad on time even though first time im going to do a conservative depth of cut per pass i think the quality is going to be quite a bit better than the plasma and also the radius of the corners will also not be that bad as it would be 3/64th radius. endmill coming tomorrow going to be getting steel during week try first shredder this weekend. generating g-code now for shopbot.
  27. 76th Week: 5/30/2017

    Enjoy your vacation !
