Different make, identical dimensions.

 

they are different design ow...welding provides better consistency for a finished product with a perfectly made jig. powells first ersions were all cnc i use to have them. powell still used cnc mounts when the otheres were released

 

um sorry but cnc is a lot more consistant then welding. if u have and operator who knows what they are doing. there is a lot more that can screw up a welded part and cause it to be off. to much heat, cooling to fast. porosity in the weld that u may not see making the weld weak. weld *********** not good enough, to small of a weld. I could go on. cnc once the program is made all the parts are the same, unless there is a bad tool in the machine or the temp in the shop drastically changes and the metal expands or shrinks by a few thousands of an inch. but I highly doubt that would matter with a mount.

 

If you have a welder that knows what he is doing it will be just as good. Its a small piece that can be moved around easily. I think you are over complicating things :p

 

no not really, I work in a weldshop/machine shop with mills and robot welder, and human welders, and plasma and lasers and benders and brakes and all that bs, and I see exactly what can happen, and happens on a daily basis when when issues come up and parts fail qa its not over complicating things. even with a perfect jig, something small can happen and the jig is out just a bit and a lot of parts have to be scrapped or redone.

 

Bro we are talking about sway bars and mounts. Simple welding. In the shop you have luxury of welding in the easiest positions, making jigs to simplify thing's, nice comfortable working area, radio on, prob a coffee and donuts beside you. If you're having heat problems, porosity, not enough weld, improper *********** welding in simple positions your welder needs some more practice.

A small example of a day in the field. We have shop guys too we always like to raze each other back and fourth a bit. They make some beaut looking pieces in the shop but in the field you gotta step up your game to achieve passable welds. Especially since most our work is Old material to new. new to new is a pleasure to work with. @ 1:35 neat weld.

 

Should I take your lack of a response as you admitting you were wrong?

 

Lol u obviously haven't seen my crowded ass work place. Not exactly how u think. Could be, but the owners of the company are a little ignorant

 

I'm not admitting I'm wrong, you're just good at lying.

So is or isn't it the exact same mounting point as Powell's then?

 

cnc can or wont be more consistent. if the vise wears or any of the fixturing holding the metal is worn or has other issues or the material is different its not more consistent. just like anything cutters need to be changed, programing needs to be adjusted, the machine itself needs to be serviced and so forth. the material itself can cause issues as well..... ive seen cnc machines run the same part out of the same material but the material came from 2 different companies and the finish comes out way better on one vs the other.

i get your point and for a complicated part sure it can be more consistent and without a doubt faster but unless its a 1.5 million dollar 5 axis cnc that automatically feeds material at the same rate and uses the same consistency an operater is putting the material into the cnc mill. at that rate if its put .001 or .0001 off it could compromise an entire part if you see where im going. atleast with a SIMPLE design like johns mount it can be equally replicated each and every time with a proper fixture and good welder vs a cnc'd version. a good welders weld will last a very very long time and a good welder should know what they are doing.



anyways none of this has to do with the ops thread. so lets get back on topic here.

 

Eumm what was the topic already? lol!

 

Edited list. Based on answers and personal research.

 

in both cases, part usually gets checked before it goes out the door, so they will both be good. just with welding, some people are lazy and cover up their porosity with more weld, which makes weld likely to fail, it all depends on the welder I guess

 

That's a bad welder. Are your welders CWB qualified?

 

or aws certified.... another thing is that all depends on the type of weld, the joint, the part etc etc etc. not all welds need to have 100% *********** based on the part. some welds are appereance welds, some 100% structural, and so forth. every weld plays a different part depending on whats needed. othertimes you have multiple pass welds which if done incorrectly can be just as bad.

yes your right about parts checking but in the end whos going to grab a mic or a caliper and put every single part through a 100% quality test or have a 45000 dollar oasis machine to check things at a high rate of speed and so forth. when you make enough good parts a lot of places go right from machine to the box with random samples here and there now days as the quality is depended on the operater and machine before it ever gets to the box.

also depending on your welding type and material porosity cannot be covered up. i know with tig its very hard to cover up porosity especially on stainless or aluminum and 95% of the time it will show as still somewhere. best bets to grind it out and start over.

 

Ya lol some of our welders are not certified, thank goodness we don't make car parts lol. But ya they don't usually get past qa. They put the certified welders on the hard stuff. If I need something personal welded. We got 2 awesome tig guys, they do unbelievable job.
