    Thanks for the help. I’ve been so sold on the belt driven Taiwanese version for so long but now taking a step back and looking at the bigger picture. I plan to mill tool steel and also small stainless parts. Thanks for the helpful comparison! Not too many people have both at the same time. 😂

      @@RodlessReel Yes I've had the "luxury" of having both at the same time lol. The 727 has much more rigidity than the 728 so it's probably the better move. It's easy to switch the gear knobs to each of the 6 different speed ranges as you need them. If you're gonna mill hardened & stainless steel you'd probably regret having the 728.

    I had a pm 25 mill , then I bought a pm 727 omg it's far far better and the 5" precision vise fits perfect, I removed , cut the back lip of the 5" vise with my band saw ! And I have full vise motion! On the table if you get the 727 definitely get the 5" vise , modify it by removing the useless trim rib lip on the back of the vise and you will be much happier than the 4" vise !

    Thanks for the video. If you still have both mills it would be very nice to know some metrology differences between the two. PM says the 728 is higher precision but they don't give tolerances when asked. Perpendicularity of x,y,z axis and spindle runout would be good to know.

    • @grippimatt
      @grippimatt  2 года назад +3

      I don't have the 728 anymore but that brings up another difference between the machines. The column on the 728 bolts to the base from underneath so that you have to have it hanging over the edge of something to access the bolts if you need to tram the head. I had to do this to my 728, the Y-axis was off by about 5 thousands of an inch. The 727V has the bolts accessible from the top, making it easier to tram the head. Tomorrow I'm gonna upload another video about the PM-727V.

    Matt, I've had a PM 727V on order for nearly a year now. For the same reasons as you I wanted the beefier machine. Yes there are some features of the 728 I like, lube system etc, but I like the geared head. It's also supposed to have variable speed as well.
    PM keep giving me various reasons why the 727 hasn't been delivered and I'm beginning to think I'm being messed around. PM have a good track record for service so I don't understand that they would risk that reputation. At the beginning of the month the answer was they don't have a shipping date yet.
    I've ordered mine with 3 channel DRO installed in China. Maybe the chip shortage has something to do with the delay. How long did you wait for yours?

    Matt - this was a really well done comparison! Can you do me a favour? On the 727V can you measure with the table full right from center line to the tip of the hand wheel? Basically how much sticks out past the mill on the left hand side with the table full right.
    Also - subbed :)

    • @grippimatt
      @grippimatt  2 года назад

      Thanks! Just measured this and if I understand you correctly, with the table as far to the right as it can go, the left hand wheel (excluding the handle) sticks out 1.125" to the left of the cast iron base. Let me know if this is what you're looking for.

    • @SomeGuysGarage
      @SomeGuysGarage 2 года назад

      ​@@grippimatt wasn't exactly the measurement I was thinking (was looking for from center line to left hand wheel with table at full right) but this works too since PM lists the base width. So really with table full right, based on your measurements there's barely any overhang to left.
      I have a small work space like yours (check our some of my vids if you want to see)...so was trying to figure out if I swapped out where my drill press is for this mill, if I could not have it stick out too far if I just kept the table to the right when not in use.

    I enjoyed your comparison. Well done, short and to the point! I have been thinking about the PM25MV vs the 727V but your video has convinced the small extra $ is well worth it. This will be my first mill (I'm a retired self taught mechanic/welder/fabricator with zero milling experience). I'm tight for space - with the 727V can I get rid of my mid-size drill press?
    Thanks - - Craig

    • @grippimatt
      @grippimatt  2 года назад

      Hey Craig, if you have a benchtop drill press then I'd get rid of it once you get your benchtop mill. Most of the time I use my PM727V as a drill press anyway. With a keyless chuck it's pretty quick to operate. I'm pressed for space like you but if I had a shop or more room I'd want a dedicated drill press so I can leave my milling machine set up for milling. The main difference between the two operations is the head height. When you have a drill chuck on the machine with a drill bit you need to raise the head 4 to 8 inches to clear your work piece. Not a huge inconvenience, especially with the Power Lift but ideally I'd like to have a dedicated drill press.

    • @grippimatt
      @grippimatt  2 года назад

      Hi, I think you're referring to the stand they sell with each machine but It's not very heavy duty from what I can tell. It's all made of sheet metal that fastens together from what I can tell so to answer your question- no, you don't need their stand for either machine. Any heavy duty alternative is gonna be rigid enough but I wouldn't recommend leaving it on caster wheels because the whole stand will shake when you're milling even if the wheels lock in place. You'll need something with leveling feet.

      @@peterantley I appreciate the offer but I think the determining factor for you is how heavy of milling operations you're planning on doing. A benchtop milling machine is really intended for light to medium duty milling operations. At 470 pounds, the 727V can handle some decent cuts but at the end of the day it's still a benchtop machine.
      I should add that I'm no expert. I use my machine to run a small business and only occasionally use it for precision work. Most of the time I use it as an expensive drill press. My grandpa was a tool & die maker and I've taken machining courses at my local community college in addition to my background as a welder/fabricator. For all the machining work I've needed done as a professional fabricator, the 727V has handled all of it.
      Another thing to consider is what your shop space is like. I chose a benchtop model because I'm operating out of a standard home garage so space is limited and I don't have room for a knee mill. If you have space for a full size knee mill I'd recommend that but most of us don't. Enjoy the family lathe - that sounds like a nice machine.
