it’s generally cutting more vertically than when I used it a few weeks ago, eg, my cuts didn’t have a slope to them.
before I started, the bed was not nearly high enough, and the bed was bowed upwards, eg “concave”. It seems the back of the bed was caught on the frame, so I lowered it down and pulled the bed forward, at which point it moved freely, and came up high enough to focus properly.
it looks like the laser is out of alignment when cutting on the forward right corner (towards the control panel) like the laser is diffracted inside the tube and cutting two lines. I noticed this on a few pieces. I’ll see if I can find a sample to get a picture of.
@derpko had a look at it last night and we think the issue has been solved.
This does bring up the issue of if there’s a problem with one of the machines you work with PLEASE deal with it or tell someone
Clay Space coordination meeting Monday April 10 4-6pm
I wanted to share the draft agenda of the meeting on Monday April 10th 4-6pm to coordinate the Clay Space development and invite you to attend, if you are interested. It is quite a project and I look forward to seeing Makerspace Members empowered with yet another capability.
Clay Space Meeting
Monday, April 10, 2017
Invited: Amanda Eccleston, Janet Whitehead, Karen Clark, Cheetie Malouin, Vaughn Warren, Kile McKenna, Grant Fraser, all Members welcome.
Build-out and Install of Clay Space and Kiln Rooms:
• Review Community Arts Grant timeline and planning confirmation
• Materials and plan review going forward - double check requirements and get ready for install
• Mitigating impacts on other Spaces in building during major install
• Gathering and scheduling volunteers and support during install
Coordinators and Members:
• Coordinators roles and how to support them (keys, materials, scheduling, etc).
• Focusing on ramping other members into the Clay Space so they can use it confidently and grow it.
• Quantifying how many Keyholder and Drop-in memberships are baseline for successful operation - goals to meet in that regard.
• What is the formula for what Members pay for workshops and how to ensure everyone’s needs are met?
• How many workshops offered per month, in addition to ongoing and accessible free-form use - at least 2 per month by diverse instructors.
• Signs and rules for the clay space.
• Kiln set up
• Clean up schedule/ cleaning routine
• Where are we in relation to the funding?
• What do we really need money for next?
• How can teachers make money?
• Firing fee?
• Other fundraising ideas
• Other potential instructors and players

@kile lets dial you into the discussion about the Classroom reno, the Social Planning Grant requirements related to it, and the opportunity to do the Classroom AND the Kiln Room in the same window. We need to avoid middle May for reno’s, because of Kathleen Raven workshop and 100th Hack.
When I used the machine last I found that the oil was not dripping down through the little window in the front of the machine, even when I ran it fast. I do not know how oil pumps work in these machines, but I understand from the instructions that the oil is always supposed to be moving through the window. I checked the oil level and it seems to be fine, so there may be something wrong with the pump. The oil pump looks like this:
I demonstrated on my tiger wheel instead but I did show how to use the big wheel anyways, I just didn’t throw on it. No rush on working on it as I won’t be demonstrating on it for a while. But new people can use it to their liking.
@clarkwerk Absolutely. Aluminum in the presence of most strong acids reacts to produce hydrogen gas and heat. In large enough quantity you get fire or explosions. (When I was in high school, we used to fill garbage bags with H2 gas by taking a plastic conainer of H2S04 or HCl, dumping in crumbled balls of aluminum foil, and throwing the bag over… Don’t ask what we did with floating bags of explosive gas!) In small quantity, the acids will cause pitting of the surface of the aluminum, which increases the surface area of the pitted part, which then reacts more rapidly… Causes pinholes then crumbling.
We passivate stainless by soaking in strong acid until the iron at the surface is eaten away, leaving a chrome and carbide surface (which is mostly non-reactive to the acids)
We have placed on long term loan a delta chop saw that was given to us by Michelle’s dad. It is new old stock. Practically new because it only saw really light work. Old enough that it didn’t come with a finger guard. Heavy enough that I had to brace the table.
i found very thin scraps of ply on in the Mt Paul industrial area where it is used in shipping. They were happy to have me take it away. There is also a gazebo/deck manufacturer that puts out tons of scrap–in this case non-ply, and they are also happy to have you take it away. Let me know if anyone wants to meet for me to show you these places.
Laser is back up - I bought and installed a new 12’ USB A-B and Kile and I installed it in such a way that it does not get beaten by users. Laser freely, brothers and Sisters.
And thank you to @Pierre who diagnosed the problem in 2.4 secs.
