That's pretty surprising. Not really more expensive than stainless for the small size I need. Can it be drilled with cobalt hss? Also is it difficult to tap?

Unfortunately I don't think my small lathe (pm1228) is up to turning h13. Not sure if it's always prehard. I was looking into 304. But I see it has a much higher thermal expansion.
I would...
Thank you for your reply. H13 sounds like a damn good material to make one from.
I realized that making it from 1144 is essentially a disposable barrel.
I thought about useing something like...
Hello everyone, I'm planning on building a ram style plastic injection molding machine and wanted to know what materials people had good results with for the injector barrel and ram?
I don't plan...
Hello, I'm looking for and alternatives for my Fuling dbz312b003.7l2dk. It's a 3.7kw 15 amp inverter.
It's for a 3kw 400hz 24k rpm spindle running on 220v single phase. I the inverter I have...
I really don't. I don't see at all how it's necessary other than voltage sag while draining batteries. Which was my reasoning for considering using something along the lines of a power conditioner....
Hello, I'm trying to find out if it's possible to run my stepper drivers on an off-grid solar system from something like a 24 volt audio power conditioner supplied by deep cycle AGM batterys?
I...
So if I move the Gantry instead of the bed I would think I would have less backlash throughout the print since the Gantry would just be moving up. Where if I were moving the bed down instead it...
Regardless of if the bed or Gantry is moving vertically wouldn't a gear reduction on the screws at least reduce the backlash? I've heard of people having problems with repeatability. I'm not sure if...
That's very true about the belts. Initially, yes I thought it didn't make much sense to move the bed. Although plasma arc welding is one of the fastest welding methods. My gantry is using direct...
Thank you for your response, that's more or less what I had expected. I suppose the best option is to go with a counterweight and use belts. I guess I could add weight to the counterweight as the...
Hello, I've been working on a metal additive manufacturing machine for a while now and I'm still trying to figure out if there are any real drawbacks to using a chain drive to turn 4 screws. My...
I was curious if anyone has tried to use the 3 hp 6,000 RPM spindle motor from automation technology on a similar Mill? I recall someone doing this on a Grizzly rf45 clone. But don't remember if they...
It seems as if this f/o/r swich would have been wired into the auxiliary board the same as the ws180 mini lathes. I had bought a 12-volt dpdt to hook up as a latching relay to enable the kbic from...
Hello, I'm trying to figure out how to wire up the f/o/r switch that came with my lathe. Its the ZH-A. The same one that's in the grizzly mini lathe that you can get replacements for from Little...
Hello, I was hoping someone could give me some feedback on whether or not it would be necessary to insulate the shaft of a stepper/servo being used as a wire feed for a high frequency pilot Arc start...
I've been building a machine specifically to fit in the back of a short bed or cargo van. From memory I think the controller is drawing 400 watts. With spindle and small computer I would expect it to...
I'm interested in learning more about this concept. But specifically with an RV power inverter installed in a cargo van. Could it really be as simple as going with a pure sine wave inverter with the...
Just a little update on progress. I managed to buy the duel arc 80 on the used market as well as the water cooler and cables . I still need to test and make shore its all working. Then buy the wire...
I'm shore it can be performed better by some than others but ultimately other than adding drain holes for the powder in your cad model your kind of limited in the internal structure with powder beds...
I plan to build 2 machines of the same work area.
In a bridge mill as in a moving bed with fixed gantry design for the y axis is by far moving the heaviest load. While I don't know if I will use 4...
Thank you for your response underthetire
Generally yes it does seem more crude. I think you could get grate results with a plasma welder like this Pro-Fusion: Micro Welding: TIG / Micro-TIG this...
Hello to everyone reading. First time poster from northern California.
