Had to edit to correct Dave's email address...
Gonna be a quick post this morning, just wanted to throw this out there. For those of us who have been waiting, it is now available. Dave from Arizona CNC Kits finished the conversion for the PM833 series mill. It is not on his web site as of right now however you can send him an e-mail at davedaxx1@yahoo.com and if he isn't flooded with too many emails already he should get back to you fairly quick. I am working on getting mine installed slowly as I am doing a few upgrades to the oiling system at the same time, that and the lake of time between work, school and all normal house responsibilities doesn't leave much time for play, however I will post up pictures as I go.
The kit does give an increase on a couple of the axis as for as overall movement, Z is limited to about 20" (sorry I don't remember the exact #off the top of my head) just do the the design of the mill column and slide, there is a bit of gain up at the top with the kit. If you want to remove the bracket at the bottom that retains the bearing for the original z motion gearing then you can gain additional travel at the bottom, however there may be a risk of the column flexing and the z getting a little sloppy without it. My understanding is this is a problem on some of the other PM mills (940 for example) that do not have the additional webbing in the z column that the 833 has. It has been a minute since the last time we measured X axis so I don't remember what the travel with the kit installed is, but as soon as I get it installed and moving I will post numbers here. Y gets a fair upgrade in movement, If you want to take the table from extreme to extreme you get just under 12" of travel and can get just a hair over if you clearance the bet a tad. That is with the table slide hanging out over the end of the bed almost over the motor.
As for hardware, the Kit includes everything needed for the conversion. Z motor bolts directly to the top of the ball screw so there is no belt to worry about like with the heavy metal kit. With the way the z slide is cast it can be a bit tricky to get the ball screw in place but not horrible. Everything is double ball nut, X and Y are a 25mm ball screw and z will be available with either a 25mm or 32mm option. Yes a 32mm ball screw will fit, the slide needs to be flipped, more on that when I start posting on the install. But for now here are a couple of pick. Any picture with components installed are loose fit right now, I will add photos as things get finalized.
I will working on getting photos uploaded directly here later but for now... Here are clickable links to google.
