  1. Hello.
    I have written to you six times before but have never heard back from you. This will be my last attempt, though I will welcome your reply if you ever do choose to provide it. I would greatly appreciate a response, as I can assure you that my query is legitimate. I am simply a homeschooling mother seeking to help other homeschoolers.

    My original query contained important background information about my reason for writing, so please refer back to that if you'd like. For the sake of brevity today, though, I will simply copy my original questions below. I hope you might reply within the next couple of days:

    1. Have you already altered any of your materials for the purpose of aligning with the Common Core Standards (CCS)/Next Generation Science Standards (NGSS)/College, Career and Civic Life Standards (C3)? If so, which materials? And what, specifically, have you changed?
    2. Do you have future plans to alter your materials - in large or small ways - in order to align with the CCS/NGSS/C3? If so, which materials and what changes do you plan to make? When will you make the changes?
    3. Have you chosen to advertise any correlations between your materials and the CCS/NGSS/C3 even if you haven't changed any content in the process?
    4. Do you incorporate materials from other vendors into your program? If so, which companies?

    Thank you very much for your help.

    Most sincerely,

  2. Tina, here is one of my responses on G+ to you:

    +Tina Hollenbeck Sorry, I haven't received your emails. I am not familiar with any of the standards that you listed, and do not have any plans to align with them. You're welcome to link to my channel or videos, of course. Please do not download, re-host or make clips of my videos. Thanks.

  3. Ben,
    Which Stainless steel bolt (size and thread pitch) did you use for your Accustream A2 Waterjet abrasive body head? Also, what size stainless tubing and ferule did you use to adapt the head?
    Thanks in advance.

    Cabi~

  4. There are some commercial ~4500 psi pressure washers that can be had used for a $1000 or so.

    I am curious how they would perform, especially on steel and if they would be at all cost effective with the high cost of garnet.

    I'd love to see it as a finale to your waterjet videos. Love the videos, cheers.
