[sudo-discuss] Is there a welding hackerspace support for Revolution Books in Oakland?

http://RevolutionBooks.org needs to make 50-100 a-frame sidewalk-sandwich-boards out of angle iron very similar to construction barriers https://mollybandme.files.wordpress.com/2014/06/summer-construction-016.jpg to mount posters promoting out weekly events Is there a hackerspace that does welding in Oakland? I either need to find a welder to donate labor or someone who can support me inexperienced doing it myself welding / cutting / drilling the pieces together - or do you know someone at The Crucibile who could support this? The photos show the first draft of our simple metal signs made out of angle iron and in the background, you can see the current version and size of our 4x1.5' posters. Rev Books is fighting American fascists and has come under attack 9 times this year by the alt-right. There are many other reasons to support this bookstore which is part of the center of building a movement for revolution in this country. Jacques
