The best one I bought - gave away the others (toys) - is a Western unit, brass and steel. I took the orifice out and opened it up with a little wire drill, about 15% on dia. Now it makes heat, light, and sound - with a 3ft flame.

You can get an idea from the photo, annealing a 6ft bronze gong.

Used a Victor torch for years and then tried the pistol grip Dillon torch which welded nicer but put my hand close to the heat and it always felt a bit awkward to me, I was so used to conventional style torches. Lately Iíve been using a Meco Aviation Jet with Kentís extra flexible hoses. The gas valves are spaced 180 degrees apart so you can lay it down on itís back while burning and with Kentís hoses it never rolls overÖÖ kind of a fire safety feature. It also takes a cutting head and is pretty light with itís aluminum body. To me the only drawback is it isnít manufactured anymore so tips and parts have to come from eBay. Damned shame, Iíd love to buy a rosebud type tip for it. ~ John Buchtenkirch

P.S. When I first got Kentís hoses I thought they wouldnít hold up, they just looked so small. Now itís 8 or 10 years latter and still no problems .

I'm going to go over to the welding supply place in town and price oxygen and acetylene tanks. What size would everyone recommend? I know they have oxygen in R (20CF), Q (80 CF) ,K (244 CF) bottles, and perhaps others. What size would you recommend?

Also, how do you transport larger bottles? Currently all I have is a Q argon and a R CO2 mixed gas. These are small enough that they strap in easily in the pickup. I just wonder about the larger bottles and transporting them.

Do you want to lease tanks or buy them? Do you weld enough to justify leasing? Do you want to exchange them outright when filling (small tanks, fast and easy) or go through mandatory inspection process with larger owned tanks every time you fill them? Talk with your supplier about your plans and their guidelines. I hear some people exchange larger tanks through a friend or employer's lease contract but I don't.

As mentioned, here in SC 40cf tanks are the largest that can be owned and exchanged outright so they best fit the way I weld. Last time I checked, 40cf tanks are approx $200 new and I've bought them used from $40-$100. They do expire at 10? yrs so if you buy used check the manufacture dates and rotate ones you might have. Duplicates extend your welding ability. After the last time at RockHillWill's, now I want to set up a pair of my spare tanks like he's done -with a dedicated rosebud torch for annealing to save time when working.

Same with transport- your welding supplier can tell you what is legal in your area like capped tanks, no regulators and specifics about what is both safe and allowed. A simple corral, crate or rack to use in your truck keeps tanks, truck and you safer, no matter what size tanks.

I stopped by the welding supply house yesterday. Like the argon and mixed CO2 mixed gas tanks I have from them you buy the tank and exchange it when emptied. They take care of tank maintenance. I actually exchanged a CO2 mixed gas cylinder that had been expired for about 5 years without issue.

I have to decide between a Q (80 CF) or a K (244 CF) for the oxygen and a #2 or #3 acetylene. I'm probably going to go with the Q and #2. The tanks are only $180 each plus the gas fill. If I decide to go bigger in the future, they will credit the purchase price of the smaller tank to the purchase of a larger tank. But, if I find the tanks limiting, I'd likely just buy a second set.

That is a good size and easy to transport.

Good info- your post made me want to check with a different supply house than I've always used since opening the studio. They handle larger tanks up to 125CF for purchase and exchange outright, so glad to know there's a better option. Thanks.

Default Gas bottles, how to acquire

note: after I had my account at the local welding supply for a while, and had a few bottles on lease with them, I bought an old gas rig for the bottles. Tossed the old stiff hoses and the cheap regs, gave away the torch and parts, and took the bottles in to be filled and changed to my account. The deal to transfer the bottles over to my account was just a basic charge to list them ($35) and fill them. Done. They assume I'm reputable and not out filching gas rigs .......

My projects vary so much that I often go months without ever lighting a torch, so leasing just doesn't fit. Some guys cut and carve stone with a torch (or thermal it to pop off tattle tail tool marks- aka cheating....) but that's not my thing.

This welding shop I've been using has always been good to deal with, but I checked with them again recently about the largest tanks they would sell/swap. Surprised to learn the other shop in town has much different operations when I called this AM.
