Oxy-acetylene cutting and safety

by Marc Juul

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? -- Marc

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

We have a metal-dude

by Morten H. D. Fuglsang

Ninjas! Jehan who taught us to weld while drinking beers the first day we met, isn't working his day job anymore. It sucks, but it rocks for us -- he's now into coming around from noon on Fridays, and be part of the team (at least until april when he might move from the Bay) - so he can be our inhouse metal-dude. Awesome. Please welcome, Jehan! Hooray! Make a great day, Morten

Metal-picking tomorrow & Lost Mails

by Morten H. D. Fuglsang

Ya'll, Tomorrow we're picking up metal, gasifier, and... Was there more? I suggest meeting 1pm outside the shop, ready to go. Rembmer road-trip music :] Tom and I made a shopping list, and Tom may have some connections for getting what we needs cheaply. It seems the sudo listserv has been out of order the past few days. Hopefully it works again now so that you all may receive this. I'll resend some things that I sent out the past days too. Make a great day, M
