How did the bending go? When you heated the Ti, did you have to worry about oxidization? I have also read about needing to heat Ti to bend it, but have never seen or done it. Is the heating similar to the heating that occurs in an exhaust in use? I have heard the coloring of Ti exhausts' is simply s...

If you have a non food oven the part will fit in, bake it for 20-30 min. per inch of material, roughly, at about 550F, or till it turns a nice blue in a clean section. That will give you a full temper, retaining a good hardness and bringing back some toughness. I'll post a pick when of some tempered...

Funny, I'm teaching a workshop on heat treating in the morning. The "tester" you asked about is for placing a metal on the Rockwell hardness scale. There are lots of testers out there for a range of prices. I find the best place to find them is from drag racers. They use them to verify clu...

Those look awesome! We are just putting a blacksmith shop together at work and I'm excited about trying my hand at forge welding. From my research so far it seems like so many other old world skills in that you just can't read yourself into know what to do. That being said, if there are any good res...

I'm down for a prototype. I'm not sure I could add much in the electronics department, but mold making is another story. When you get to that point I'd be glad to help.

^^^^^
That thing is awesome.

That's certainly a possibility. If you want to save money. You provide the artwork and I can cut the vinyl at low cost. This is the free software that I use. https://inkscape.org/en/ The software works on Windows, Mac and Linux. You will also do the weeding, as I hate this part of the job. :roll: &...

A vinyl cutter is one of those machines you never knew you needed till you get one. Not sure if anyone would want to, but if you put a vinyl sticker on leather, say the back of your welding jacket, you can use a heat gun and make it stick. It's how they put sponsors logos on racing leathers that are...

Good to hear good things about green and nice report Coolide. I have been eyeing the little 125 ac/dc machine from them as something to throw in the van at the track (motorcycle racing). I know I have wished I had a welder a few times after a spill, and I know I could pick up some good karma, and ma...

I've been using the air diffuser also for many years, here in the states I find them at McMaster Carr listed as pneumatic air mufflers.

I just found a pile of those suckers in a pipe fittings drawer at work and that the same thing.

We have an arclight with a 4x8 water table and 85amp hypertherm. The water table is nice, but requires some upkeep. We also have the indexer for pipe, which works really well with the table. We run Mach3 with it. I generally like Mach3, which we run on our other CNC's, but am not a big fan of it for...

What kind of paint are you guys using? We sealed our whole shop floor with an epoxy. It works great everywhere but the welding room. The epoxy melted and burned quickly from any sparks that touched it. We ended up putting down aluminum diamond plate and welding the corner together. Im not sure what ...

I have built a number of adaptive controls for folks, but never a welder. I work with a group locally called May We Help. They are a volunteer outfit who take on such challenges for community members. I think you are on the right path and would reach out to your PT or rehab providers.

how can you back-purge internal tubing sections with an external trailing cup?? Let me try that sentence again. Would purging the front with a trailing cup and regular torch flow and purge the back by filling the tubing with argon be sufficient. As I count I would need 3 lines. One to the torch, on...

Thanks for the feedback. The article is a good resource, so thanks ldbtx. I probably should have started this post with 3 statements and a question. 1) I have never welded Ti. 2) I have designed and welded many role cages and other frames for that try to stay close to the ground at speed, but never ...

Anyone here play with Ti? I have a member at my shop (I work at a Makerspace) who wants to build a plane with a Ti tube frame. He is not really a welder. My first instinct is to tell him he is nuts and run far away from this project. The part of me that is interested in welding new materials that I ...

I keep my old mig and stick only rigs out in the cold portion, but the TIG with the water cooler in the heated section in the winter. Done it for years, no problem. I'd probably keep the TIG in the cold if not for the coolant.

Seems to have posted twice and I can't seem to 86 this post.

On the other side of the spectrum http://images.tapatalk-cdn.com/15/04/25/7886545c1b6e2ba67df47b88ca937ed1.jpg A wild tiger could get through this. It's a frame for a stepped divider in my Sprinter. The bike wheels go under in the back and a bed goes over it in the front. http://images.tapatalk-cdn....

I like the idea of having CAD, CAM, POST and Controller all in one package basically. All too often I find something at the CAM stage that needs to be fixed back in CAD. The windows stayed pretty clean as well. I like a busy screen cause I want to know what is going on with everything at a glance. I...

I am interested in Mach3 alternative as well. I don't mind it now that I have spent a year using it on three machines, but it can be a bit overwhelming to unpack by your self as a first package. I'm always looking for ways to make our machines more accessible to members. Let me know what you think i...

I'll have to try and stop down there before I head back to Pittsburgh for good. I'm up in Lima, but I used to help out down at the Motorsports Country Club in Batavia on the weekends and stuff so I'm pretty familiar with the greater Cincinnati area. Stop in any time. We always have someone availabl...

Carved spoons you say? I'm always looking to add to the curriculum.
