Yo peoples,
The oxyacetylyn torch handle and tube-valve-stuff is at 2704 Adeline St.
Marc and I are on our way to big sur so wont bring it in Saturday, but one
of you peoplez can go by and pick it up. Theres usually someone home around
noon. Just knock.
Also, remember to put on the check valves or you will die. Seriously.
Make a great day,
Morten
Hi Alaric!
Thanks for getting in touch. The address of Eric's workshop is 953 w.
macarthur in Oakland. We will be welding a soil grate, and some other
stuff, we will also be cutting things, grinding things, torching things,
and dropping them on the floor. We will also be drinking and barbecuing.
Feel free to bring beer or things to grill, although it's not required.
We need to also reverse-engineer some possibly buggy shop drawings from
Open Source Ecology.
We have 3 MIG welders, one of which I am sure we can use, and two that we
will need to buy wire and tips for. We have a bunch of gloves and face
shields, but feel free to bring your kit.

Hey you makers of things you!
I am Alaric, and want to help you weld/build/make/fix stuff! I think your project sounds really neat and I would like to be able to become involved.
A few questions, I hear you're meeting on Saturday at noon, where exactly will that be? Will we need to bring equipment? If so, what do you need? What sort of things do you need done (welded, hit, looked at, fiddled with)?
Awesome, thanks!
Also, my tweets are at @apisgirl which is a good way to hit me up for stuff and what-not.
We were talking about hot springs in Big Sur. Try this, about halfway
down the page:

I'm racking my brain to think of a glorious Central Coast natural hot
pool that I went to, reached by a short trail, and virtually unused.If I
can think where it was, I'll send another email.

We downloaded http://opensourceecology.org/wiki/File:CEBIVFab.pdf.
Unfortunately,
some of the measurements were wrong (the slats on the grate). We will be
able to fix the wrong cuts we made, but it would be nice if the most
current versions of the plans were made prominent on the site. Is there a
more current version we could download?

I've been trying to find an oxy-acetylene cutting torch handle at a
decent price.
The cheapest one I've found is this one from harbor freight at $55 +
tax and $7 shipping (1-day shipping):
http://www.harborfreight.com/18-inch-oxygen-acetylene-cutting-torch-96290.h…
Two problems:
I'm not 100% sure that our hoses will fit it (though very likely it will).
It comes with only one cutting tip, a #1 size, which is used for
around 3/4 steel, whereas for 1/8" we should use a size 000 or size 00
tip. We _could_ probably use this tip, but I'm not sure what using the
wrong size tip will do.
It's possible that we can buy a replacement tip, but not from Harbor
Freight as they only sell the #1 size, and I don't know which other
brands are compatible with this handle, if any.
Another one I've found is this a Harris brand cutting torch for $75
including shipping:
http://www.ebay.com/itm/Genuine-Harris-Ironworker-Cutting-Torch-w-Acetylene…
This is certainly much higher quality, and it has the advantage that
new tips are easy to buy in all sizes. With shipping it is $13 more
expensive, but for a much higher quality product. Another good thing
is that it is more likely to fit our hoses, since it's a harris
product as well.
Two problems:
We will probably have to buy another tip, since the included is size
#5 (recommended for up to 5 inch metal). The new tip will cost $10 to
$12 including shipping.
We may not get it until after the coming Friday (though we should
have it for the next Friday). I have asked the seller about faster
shipping options.
Here is a nice image showing the difference between the different tips:
http://www.ebay.com/itm/2-Acetylene-Cutting-Tips-6290-Size-00-for-Harris-To…
Here is a chart for tip sizes:
http://www.hoopersupply.com/tipchart.html
I've also looked at other equipment, and I think we should get:
5 pairs of impact resistant safety glasses at $2 each (for ourselves
and visitors when just standing around / cutting / doing basic work):
http://www.harborfreight.com/impact-resistant-safety-glasses-94357.html
1 adjustable untinted face shield at $15 (for use with safety
glasses or goggles):
http://www.harborfreight.com/adjustable-face-shield-46526.html
1 set of two fiber tip markers at $3 (for marking metal):
http://www.harborfreight.com/industrial-marker-92925.html
With the Harris branch cutter and extra tip, these expenses total
$121. With the cheap cutter and no extra tip they total $90. Split
over four people that's either $30.33 each or $22.50
Another option is to not buy any cutter and try to borrow one for at
least next friday.
What do you say?

Angles, box-sections and flatbars, in any width - above 1 foot long!
Just joined the list...heard y'all are waiting on / choosing an oxy-acetylene torch. Bobby (cc'd here) is pretty handy with his plasma cutter after years of keg modification etc and might be persuaded to help out for a few beers or just the additional glory. Sorry to cold-cc you here bud :)
I'll see if I can take off next friday afternoon to make next week's meetup - looking forward to checking out the operation.
Cheers,
Hol

Sounds good. Sorry for the delay. I'm down for you ordering the safety
gear too. Just cashed my check so I should have my contribution on
Friday, Thursday at earliest
