I own a Precision Matthew's 1030V lathe. Generally not a great machine....
I decided to try carriage drilling so I bought a mt2 tool post holder to utilize the mt2 tapers I bought to quick change in my tail stock. I'm going to try and do a better video tomorrow. One hand videos are not easy.  PM1030V tool post drilling I'm super pleased. I really didn't expect it to do so well. The 1/4 pilot drill took more pressure than the 1/2. I don't intend to abuse the new found capability but will sure make life easier. |

I thought PM are supposed to be top of the line hobby machines?
I have a jet 9x20 but I’m just learning I tried some drilling a couple weeks ago also but my tailstock must be slightly off center as my hole was not perfectly centered. Did you use a center drill first? |

Top of the line out of all machines? Not anywhere close to even the middle, let alone top. If I had to rank a PM against all lathes new, old, domestic, & foreign I would put them somewhere around the 12th percentile. |

What was the carriage feed?

I was thinking of setting something like this up, now that I have a DRO on my lathe. How did you go about finding the center position for the cross slide?

I did this video this morning. 1 1/8" hot roll steel. The hole will fit a 0.501" pin but 0.502" won't start.
 Carrige Drilling on PM1030V You can see the advantage to using a mt2 holder over a straight shank and clamp holder.  Attached FileSurface finish is pretty okay for a drill. |

What I've occasionally needed is a powered version of the tool post chuck holder. There have been instances where I've needed to drill and tap a hole pattern in a long rotor shaft after doing a stub shaft repair. I've solved the problem by making a hole drilling guide and then hand tapping. But, a powered drill on the lathe would make things easier and faster.
However, the lathes I use are much much larger. The smallest swing is a 16" x 128" Monarch. The shortest distance between centers lathe is a 20" x 48" Monarch. Both of these are 1951 vintage. |

I used to sink impressions in dies for 4,000 and 6,000 ton forging presses. The smallest had around an 18" chuck. The big Poreba had 3 ft chuck. The biggest lathe could have spun a van.....lol. They never used it. |

Everyday hobby us machinists push our tools and skills to their limits. Sometimes we even go a bit beyond. But how else would we know just what we CAN do ?

I really like these mt2 to jt3 adapters for making drill holders. They cost less than $12 and are less than half the cost of an endmill holder.
 Attached FileThey drill fine. I've been drilling then boring and reaming to size just to keep things aligned. I've got another adapter coming to drill for no 3 center drills. I've already made one for a no 4 center drill and 1/4" and 5/16" drills. I used 10/32 set screws. I can switch to 1/4-20 if needed. It seems to work fine so far. I put a small flat on the drill bit to help drive. |

I saw Abom using friction fit tool holders other day. They use an induction heater to heat the end of the holder and the tool slides right in.

If I had an induction heater I could have reamed my mt2 jt3 adapters 0.001" undersized and shrunk in the bits, but I see no real advantage when the drill bits aren't that accurate. |

I bought a generic ebay CXA size mt3 tool holder. Unfortunately they didn't design it well. I had to modify it for the tang to stick out enough to tap it with a brass hammer to pop out the taper.

I drill from the carriage almost more than I use the tailstock.
I recently had to drill 6" deep in aluminum. It would have been mind numbing to do it with tailstock.  Attached File Attached File |
