What I was referring to was the argument about whether cookies should be crisp or soft. One of those topics with strongly defended positions. I didn't realize when I posted that I was responding on page 2 to comments on page 1 so it made little sense.

They're back from Golden Week and I got this photo in email. My payment still hasn't appeared in their account, the banks are probably digging out from a week of backlog. They said they're ready to ship as soon as they get notice of the wire.

You guys seem to have an awfully short memory for topics cancelled when they got into the realm of religious discussion.

When you said spring, I had coil spring in mind. If its a leaf spring they're a lot easier to have made and you probably won't be incurring the big setup charge. Back when my dad had his diesel repair shop I'd work there summers doing parts runs and cleaning up. Sometimes I'd go to the spring shop and enter this noisy, darkened shop with furnaces going and people making all sorts of giant springs and then dipping them in tar for corrosion protection. A few years ago when I needed a spring I drove to the old place and found a block of luxury condos. No more spring shops here, the land is too valuable.

A lot of the time most of the cost for single parts is in the setup. If that's the case here you might think about buying several and making them available to others in your situation to share that setup cost.

A few years ago I put together a very simple heat treat oven for a friend who needed to make some transmission parts he couldn't buy. I used firebrick, some kaowool for a quick shell, two 220V heating elements I picked up cheap, and a digital temperature controller from a surplus store. I don't think I had $50 in the whole thing and it worked pretty well. You had to set the temperature each time you needed a change to ramp up or down but for one off, it wasn't bad.

This probably belongs in a general topic but since it came up here, I'll comment on it here. I know this runs a high risk of my sounding preachy and that's not the intent. Sometimes people will ask questions and then insist that what others are telling them they're doing wrong is right, or say that they'll keep doing what others are telling them anyway. In my mind, the first can be either an unwillingness to learn, or maybe its just kind of thinking out loud to elicit more argument about why its wrong so that they can learn from it. The second instance might be because someone just wants to experiment and learn first hand for themselves how things behave. I think there can be a tendency assume that the behavior always stems from the first reason (unwillingness to learn) and then for the more experienced to not want to waste their time on someone who thinks they already know it all. I think we'd all benefit from at least starting out with the assumption that we're dealing with option 2 until the posters proves himself to be in camp #1. In my case, I asked for advice on power hammer importers and got a bunch of advice telling me not to do it. All of it well meant and trying to save me from wasting thousands of Dollars. I tried to explain that I knew and understood the risk and this was an experiment I wanted to do. I wound up getting some PMs instead of a public response because some people felt the hostility to the idea and didn't want to poke their heads up. If I was a newbie trying to learn for myself if I could forge weld in my home oven instead of a thick skinned old fart, I might have given up on the forum as a place to discuss and learn. I think Xaiver and I wrote at the same time. I got a notice that he had posted and went ahead and posted without reading his. Last thing: Xaiver, in my gas forge I run 15 PSI in general so if you can get to 20 that might be all you need. I got a 30psi guage because its what the store had.

Great. I never looked at the Github, I'll go take a look. If the code needs any change or if someone comes up with new features I'd be glad to help. I've worked on a lot of things on all sorts of processors. I just took at look at the Github page. The processor they use is one I know very well. There are a couple million devices out the world with my code in them that use that processor. Easy to make changes if needed, or to just build what's there and burn the flash for whoever builds this if they aren't set up to do it.

Code requires that a 4" ball can't pass with 50 pounds of force applied to it. At the very bottom between the stair treads and the bottom of the railing, that's a 6" ball. The work looks great, and that collar is nothing to be ashamed of. Regardless of whether or not they have kids who might get injured you have to build for the visiting child or the one who might live in that house in 20 years. I built a railing for my place where the pickets had bends and twists. I placed them 3 15/16" apart at the top and bottom, but the bends and twists created spaces over 4" so the inspector made me close it up. I welded in a bunch of 4" rings with a 3" ID wherever I could fit one in. My original plan was to remove them after the inspector left, but in the end they looked nice and added to the appearance so I left them in. I never got a collar to look as good as your so I never put them on. I should try again.

Unless you have calibrated ears you should get the guage. A small difference in pressure can make all the difference in the athmosphere in the forge. You also need a big cylinder, at least a 100 pounder. The reason for that is that you'll get less gas out as the cylinder cools from use and with a small cylinder that's rapidly cooling that can make a real difference. I have wanted to experiment with using an O2 sensor from a car to regulate the forge athmosphere, but never have.

I do embedded firmware for a living. If this thing needs any microcontroller work to do a user interface or some sort of feedback control, I'd be glad to lend my skills. For instance, it wouldn't be a big deal for me to read an IR thermometer pointed at the work and PWM, or otherwise control the power, of the heater to get a part up to a preset temperature and then keep it there. If there is something that can be read from the output waveform that will allow on the fly tuning for efficiency I can do that, or it might be as simple as monitoring a few component temperatures to make sure that some expensive output stage part doesn't fry. This sounds like a great project but I know that I lack the high power electronic skills needed to do anything beyond a color by number build of it. If I can help make it better with what I know how to do, let me know.

Each of those is amazing and they are even better together. So many great ideas to steal. Maybe given Picasso's comment about how good artist copy and great artist steal I should limit myself to just saying I'm going to copy.

I just sent final payment. I expect delivery mid to late November.

It doesn't look like that grinder design would give you good access from the sides. My grinder, like the knife grinders I've seen has empty space between the front and back so you can get right into indentations and transitions in shape you're working. Maybe you can see that grinder up close before you buy and see if the parts that are in the way are removable.

Years ago I knew someone who held some sort of a commitment ceremony with his girlfriend where she was going to get branded with his mark. I didn't make it to the party and we've lost touch so I have no idea if they're still together or if she just has a permanent reminder of a bad decision. I think they used cold instead of heat to do the job.

I got email this morning with a few pictures and a video of the testing of my hammer. It turns out that China pretty much shuts down the first week of October for the national holiday so they won't be back to work until after the 7th of October. I'll send the balance of my payment and start the countdown until I get that call from my local warehouse. Now that I've bought the thing, I have some questions. Is the little petcock at the bottom to drain the oil that makes it past the rings and doesn't blow out? Is there an air filter on the intake air?

My 11 year old and I were at the spring conference and had a great time. We spent nearly all of it at the forge area participating in the project demos and working on them. On Saturday he put in a 14 hour day before I could get him to go to sleep. We were going to go to this but the description on the website made us think it would be mostly instruction by 1 person with less chance for the hour or two long "make a XXX" and some time at the forges to try it. Did we properly understand the flavor of the event or did we blow it by making other plans for the weekend?

forbidden.

I had never heard of vessel finder. That's really cool. I spent some time looking at ships moving around the local area and checking what they were. I'm sure my boss will be grateful for your mention of vessel finder once my hammer makes it to a ship and I start spending time tracking its progress.

Indeed. I couldn't see them until you pointed them out. I hope I get that video of it making some toothpicks soon. Its feeling like that last week before the start of summer vacation as a kid.

It doesn't look like there are any forklift holes. I doubt they'd be adding them now. Maybe those only start to appear with the 40kg hammers. Just as well i don't own a forklift I guess.

I'm not too worried about the schedule slip. I just found it kind of funny that there is an otherwise finished and ready to go hammer sitting in their factory and they can't ship because of the weather. Sure, I wish it was here and working, but I understand things take time and even if they had to put my order on the back burner for a few days to get more pressing or profitable work out, I understand that's just one of the tradeoffs you sometimes have to make to run a business. Included with that email were a couple more photos. I don't know how to turn the picture to show the right way, but you can see the filler on the casting waiting for paint.

More news on my hammer from the factory: Hi Mr.Philippe Habib, Sorry for replying you so later. I think I must delay the shipment date. Because our here rains three days,we don’t Paint it now.The bad weather is not suitable For painting. The weather forecast said it may become better. I wish tomorrow would be sunny day. If there is any good news,I would tell you. Have a nice day.

Since its got a square shaft with a collar shape on it, wouldn't it be more likely to have been designed for use in a hardy hole rather than pounded into a stump?

I'm sure that some have made improvements or modifications to the original design over time, but they are very similar. I think the Russian hammer for $1000 euros will be hard to beat. You could invest that much again into repair and still come out ahead.
