This will take huge cuts and still cuts smooth finishes. Now on the other hand, the TrueLine is a leadscrew-feed design much like a lathe. 2nd, the toolbit mounts are not the greatest. That is why it leaves grooves and bounces around. But we all know the cut is pretty huge.0.020 all at once. The Porta-Tool lineborer is a fine design.provided you take little cuts since it is hydraulic feed. I do not know who is Tim, but I will take a stab at this one. Posted: Sat 1:06 am Post subject: Porta-tool. But for 90.5's, 88's and 85.5's it works pretty well for me and my customers. I won't use it to open heads for 94's because I don't think it's accurate enough to keep the eyebrows even. But a tool/fixture is only as good as the operator. Yes, I wish I had a mill and I'm sure it would do a better job. I've never had any complaints on the job that it does. yes, I use a Porta Tool Fixture that mounts in a drill Press. seems like he asked a legitimate question. ![]() Location: Samba Center for Behavioral Science You do not like accuracy and precision? Do you even know which one is which? Well.somebody is on the rag! Aweful touchy, aren't we? Your the one always bragging about how good you are,accuracy,precision blah,blah,blah.Why are you asking us.īolt'em to the bridgeport, touch off on the surface and use the big flycutter to take off as much as you want. "If you don't run into the Devil every once in awhile, you must be going in the same direction!" There is more than one quality machine shop in the good ol' USA that know what they are doing. I suppose I could box them up and send them to the east coast and pay what, $50 each to get them done + shipping? Don't think so. I take mine to Solenberg Performance and they come back like I want them. I drop heads off at Engine Machine Service and its taken care of. Post away if you have ideas on how to do it best. I am just curious how things are being machined nowadays.

But when a component is held in the machined registers of soft jaws, or in the jaws of the machine vice, without tapping down, the resulting machined surface will be completely flat and true to the spindle, as there is no preasure to be released, so the molecular structure of the material has not been compremised and the registers in the soft jaws are milled true to the spindle, the resulting machined surface will also be true. ![]() What happens if the surface to be cut is at an angle to the rest of the component and so requires the head to be inclined, does that represent not being level? If you knock down on strips, then when the vice is released after machining the material, having memory, may very well return to its pre-machined condition. I don't understand how the job not being level will result in a dished surface. Further to my flycut heads not being flat, I have been proved wrong in the past, but after 45 years in the trade I think I've just about got the hang of this milling thing.
