Yeah, thats something you should do a tutorial on how you made and grinded.. it would prob. help a few others as well.. i use it for all my hogging now a days.. havent figured out how to sharpen it though without messing it upp.. so i just let it be atm ;D |

NeoTech Threading is not that difficult, there just a few things you must remember. First, new to threading you need to start one a soft metal and practice. When starting you need to set your compound to 29.5 degrees and set the cutting tool parallel to the work. Next thing bring the tool up to the point it touches the material (metal) at this point set your cross slide to "0". You must turn your carriage out at the end of your thread. If you do not have a thread gauge which indicates the position to start your thread. The better way is to #1 back the carriage off and turn the lathe off never disengage the half nuts then reverse your tool past the starting point. Stop the lathe now is the time that required concentration for the carriage must be dialed back to "0" then advance the compound a couple of thousands then start lathe in forward. This is the process for threading repeat the step from #1 advancing the compound only until your thread is finished. If the diameter is small you might want to use a follow rest. Also when threading chuck up as close leaving out no more than you need. If the thread is long you will need both a follow rest and a tail stock with a center. I hope this will help and not add more question. Nelson Collar May the Lord Direct Your Steps "When injustice becomes law - resistance becomes duty." |

If you have an inch leadscrew, the threading dial won't work for metric threads, and vice versa. You have to keep the half nuts engaged thoughout, and reverse the motor to run the tool back ready for the next pass. Cumulative backlash between spindle and leadscrew usually means the tool will widen the groove by cutting on the other flank as it returns, unless you withdraw it before reversing. Andy |

yeah i guess thats problem, i dont know what type of leadscrew its is on my machne.. i havent figured that one out yet. =) |
