The base unit is listed as the 500, which I take to be 500mm, or just under 20 inches. Pretty small. If you were to put a spindle on that gantry, I'll bet you would see some interesting deflection. No recommendation here. :nono:

    Thanks Gary,
    Yes it's pretty light weight. But it is very comparable to the cncrouterparts.com basic benchtop unit, which also uses the same size extrusions for construction and lead screws. I thought it might be a viable plug and play option. I realize it would have been more of a hobby machine than a true professional tool. I'm probably over thinking this whole thing. Just need to commit to fixing this pile and start tearing into it. That is how I generally work...if I try to plan every detail I never get started. I need to see the nuts and bolts and solve each problem as I run into them.

    I am going to cut the cross members right down the middle. This will allow the frame rails to be parallel. If I just get the rails parallel then the drives at least on one side will be misaligned. This will also allow me to adjust the cross members pointing slightly down or slightly up in new center joint to help fix some of the flatness / squareness and help get rid of any of the toe in or out of the vertical uprights. Then I can just shim the table and plane it off. I'm sure it's a very farmer like solution to some of the more educated and experienced here. Hopefully I can use this to tune out most of the issues with the frame and at that point call it good enough.

    Re: Fineline Shutdown or Perpetrating a Fraud!!

    Are you talking about a Saturn 2, cutting it apart in the center and re-welding?

    Yes it is a Saturn 2x4'. I think there are 5 cross members. I don't know if I would re weld or make some plates and bolt it.

    You're braver than me, and I'm a pretty handy guys with a shop full toys I know how to use (MIG, TIG, 2 plasma torches + the big woodworking stuff for furniture and cabinets). There is a silver lining, though. Once you've cut the frame into two pieces, it will be easier to get into your truck or trailer when you cart it off to the scrap yard.

    Either way... whatever happens...I'll know what to do next ...I just want to keep it simple and solve as many problems in one swoop as I can. The machine is up on the stand from Fine line...which has bolts holding it in each corner. Just gonna double triple check for level on the stand and then kind of use that as reference for "flat"...then hopefully it's just a matter of moving one end in to parallel. I'm thinking I will cut through all but the last cross member and basically cut all the way through just leaving one wall of that last cross member so it's not a total slop fest trying to get it aligned.

    So that it does not move around too much while cutting the other cross members, after cutting the first cross member, bolt or clamp a temporary plate or angle iron to it to hold it and then cut the other cross members

    Your opening a can of worms. What equipment and measuring tools to you have to get it aligned to within .005 or so? How are you going to deal with the warping and distortion after and during the welding? If you plan on welding and do as Mac and others have suggested take somewhere and spend a $1000 +/- to get it ground flat and true.

    Re: Fineline Shutdown or Perpetrating a Fraud!!

    Just an update for anyone who is following along...I emailed Nate last night about some spare parts and got a response this morning (quick response). I replied to him a few hours later but did not get a second reply. He did indicate that he is still in business and had the parts I was interested in. YMMV.
