For any really big stupid stuff, I can CNC something out. I can make a closed box or open end in 3/8" Ooo, hadn't even thought of that! This may solve a CJ-ish issue... |

Creepy brand wrenches.
Coming SOON! ;D

For any really big stupid stuff, I can CNC something out. I can make a closed box or open end in 3/8" we've got a dozon or so kicking around, torched out of 1/2" plate. if ya need a socket, some fancey pipe n hammer work can be done too...... made a 1 1/6" deep socket that way on a sunday morning .... what ever works |

Thanks. I actually have two 1 3/8 wrenches here I cut out with a laser. The box end is fine, but the open end needs a lot of meat around it to keep it from spreading. It is only made from mild steel. If it were made from alloy or chrome moly and heat treated, it would be better. Welded up sockets would work really well on the larger stuff.  |

Well thanks for the idea anyway! I'm sure i will need to do this around the shop at some point. I'm cutting really nice 3/8" now, as good as the 1/4" brackets I've been pimping.

not bad, what's the rated cut for your plasma jan?

not bad, what's the rated cut for your plasma jan? The PM45 is said to be underrated. 3/8"pierce, 1/2"cut, 3/4" severance (mild steel) Net guys are piecing 1/2" , but I haven't yet. You can drill start holes to cut inside profiles in thick stuff. |

for some reason i thought you had a bigger unit then that.
though you maybe able to do heavier stuff, with the cnc, i would think your quality would suffer. doesn't take much at the limit to make a bad cut

i just a couple of wrenchs at work 1-7/8, 1-3/4, 1-15/16. the cheap ones the price started at 200+ per. grey per wrench was 500+ each. i have 2-1/4 at, 700+ each if you use them the odd time, i would go cheapy wrench

ouch... i guess the $25 shipped on ebay wasn't too bad for a 1 1/2" combo eh

though you maybe able to do heavier stuff, [glow=red,2,300]with the cnc[/glow], i would think your quality would suffer. doesn't take much at the limit to make a bad cut i don't understand what you mean? How thick a cut you can take is totally dependant on the output of the cutter. The CNC moves it around. If you are on the edge of the amperage output capibilities of the plasma, say cutting 3/4" in my case, it can only help to be micro controlling the speed and tip height by computer. |

If you are on the edge of the amperage output capibilities of the plasma, say cutting 3/4" in my case, it can only help to be micro controlling the speed and tip height by computer. just from what i've seen on cnc plasma'd parts, the cut tends to get a bad taper when you approch the max thickness of the machine. these we're not parts you cut, but they were done by a large firm in the HRM. not trying to give you a hard time man. just goin on my experinces to date. |

It may just be a case of the taper being more apparent on the thicker material. I think it really depends a lot on the machine. In the manufacturing plant I worked in, we were using cnc machines built in the 70's that were 660 volt, 3 phase, and were meant for production, not show. The tip height was non adjustable, set the same for all materials, and there was even a taper on 1/8 inch material. I think it ran around 10 to 12 degrees, with a small radius at the top. If I remeber correctly, it cut at 70 inches per minute in 3/8 plate, and 50 ipm in 1/2 inch. (Jan, what speeds are you cutting at?) When I left there in '97, I read about 'high definition' plasma cutters that were supposed to give a much better and more square cut. This is probably the 'standard' plasma cutter today.
From the few pieces I have seen of Jan's, they are a really good, clean, smooth cut, and very square, approaching that of a laser. I bet some of the smaller 1/4 inch thick stuff would stand on edge. Plasma cutters have come a long way in the past few years.
Of course, I do have a few 14 gauge parts that were cut on a laser using nitrogen gas, and they will stand on edge on a flat, level surface. The edge looks like it was cut with a milling machine. ;D Purdy.

But now I disagree. ;D The CNC will always give better results over manually cutting, assuming a competent operator working at making quality cuts, and a healthy machine. There are a lot more things that can go wrong with CNC tho to make bad looking parts! Different bevel on different sides of the parts is a bad tip, crooked torch, or loose motor gears causing racking of the gantry. That is an unhealthy machine. Part quality is dependant on many variables. If all you needed were weldments, and you are hitting it with a giant stick welder, edge bevel is pretty irrelevant and speed in manufacturing the part becomes the driver. Perhaps your supplier manufactured the parts in this manner. You can chase out the bevel, or ignore it, depending on the application. Within the rated capacity of the plasma cutter, (a good one) edge bevel should only be a few degrees. An out of tune machine can make that impossible. The same could be said for a torch - if you are trying to cut say 6" billet with a little torch, its going to taper. You are over the capibilities of the torch, part quality will suffer. I don't see why you think that CNC control has anything to do with diminished part quality when cutting outside a machine's design parameters? It can only make it better! you can control every parameter, whereas by hand, you have zero consistency. The CNC lets you squeeze out every bit of performance the plasma can offer, because you are controlling every aspect of its operation. Perhaps I am misunderstanding you, throw some sentence structure in there, the commas read funny. If all you are saying is thick plasma parts have taper, then yeah, they do a little bit. |
