    It is looking more and more like I am going to be forced into 'early retirement'. I am lucky that I thought to purchase my large machines before the money tree died. :(

    And it's a good thing I bought decent quality machines, as I won't be able to replace them any time soon! :eek:

    My money tree is now broke down, it withered and died. Thankfully it lasted thru the lathe, knee mill, tooling and saw.

    I set my lathe on wood blocks to figure out the best height for me before I went about building the risers. I had hoped to make some pucks out of 3" or 4" round stock and use the factory screws but when I determined I needed 6" the pucks got over square and I was concerned about stability. My risers are made from 2" x 1/4" angle because I had 40 feet left over from a job that canceled on me.

    Well the DRO is installed. The X axis was reading 10X its actual travel so after struggling thru the so called Users Manual and a little reading I got that fixed. I think I will like the DRO. Now its back to the wiring and milling a bottom plate for the QCTP. I know what electronic features I want but just need to get started.

    It was nice having the 1030V and the Super-Max to make a drill extension and machine a couple of DRO brackets for the GT.

    I would agree with sanddan, I bought as much lathe as I could afford just before retirement and got the 1340GT with the 3 phase motor based on recommendationsfrom this group. Mksj was outstanding in his assistance as well as patient in all my basic questions. I have never been sorry for my decision.

    Mark has been a great help already. I have been abusing him and Jay for a few weeks now. I had other things that needed to be done before I could get back on the lathe. The DRO was a challenge but it is done now. My knowledge is in a very different field (drawing and building transmission and distribution power lines for a local REA, for 39 years). I will stumble through the electronics with their help, it is very different and the same.

    Great info here. I am also looking at the 1340GT and the 1440GS. I just do my own gunsmithing work and don't want to put out the money required to get a 1440GT, so it is really between these two.

    I really want a Taiwan machine as I do believe it is better quality, but just not convinced I want the open gearbox. Not because of quality of the threading or anything like that, but just the extra noise it puts out and there is a mental side of it that makes me think oil splashed gears will require less maintenance long term.

    I have no doubt either will work, but is the Norton gear box a valid reason to not go with the 1340? The size of both machines is more than I "need" so that isn't an issue. I don't think the GS comes in a 3 phase, but this will truly be an occasional use machine. I have a SB Heavy 10 right now, but want something a bit more modern.

    I can't hear anything coming from the Norton gearbox while my lathe is running. The reason I chose the 1340 over my other choices (no 1440 for me...too big), was specifically the Norton gearbox. The only time I will ever need to change a gear on my lathe is if I want to cut a metric thread. So far that hasn't happened. :)

    Hi Jay, I'm back on the lathe starting yesterday, I've been to busy for anything fun for the last month!

    I looked thru my leftover steel assortments, read junk, and found a couple of pieces that worked great to mount the VFD in and above the tailstock end of the lathe. I had two new 30 amp 4 wire plugins and receptacles that I will use on the mill and lathe. I am building a lexan plastic front cover for my 12x12x6" j box so the front controls of the VFD can stick out 1/2". I ran the shielded cable from the VFD to the control cabinet in the base. Now looking for 8' 10-3w/g shielded wire to go from the VFD to the motor. The protection scheme is next up to decide which options to wire into the VFD.

    I hope to temp. wire the control box today, or at least this week, to check out the basic functions in preparation for ordering the switches, etc. to complete the wiring. I will be in touch with you and Mark I'm sure to help with something I don't understand.

    My philosophy is it's not junk until I throw it away. I seem to have a lot of "Not Junk" ...LOL

    Be sure to post pictures of your progress.

    I'm too ashamed to post any more pictures in my shop. LOL. It has been in a constant state of clutter every since it was built. Not to mention some family members think it is just free storage for their crap. That is changing, but slowly. How do you tell your mom to come and get her junk or "I will take it to the dump when you die" politely? Which I have already done and it's still there. My tractor and a couple of trailers are just rotting away out in the desert weather here.

    On a better note, I temporarily powered up the contactors and light today, everything did what it was suppose to do. It was very encouraging to hear the contactors "click" when they were suppose to. Now I really am over my head from here on out. Going as slow as I have had to so far it hasn't been too big of an ordeal.
