    Thanks ShopShoe. Yes aware of Jody's work and subscribe to his channel. Even bought a TIG finger from him to support his work. It's great stuff.

    Pleased you are finding some interest in my ramblings. :thumbup:

    A small update on the cart. I plan to add another shelf to
    [1] support the coolant reservoir "bucket"
    [2] provide an area along the base of the cart under the shelf to hold cut-offs

    The tabs for the shelf are off-cuts from another project and TIG welded into place. That in itself was a big learning exercise. Moving from TIG welding all nice and comfy on a stool at the table to on the floor trying to align to the torch at odd angles with minimal support and doing uphill welds for the first time. Oh well, who wants to make it easy?
    :hDe: :wall: :fan:

    Cheers,
    J.

    Positional welding,o that brings back memories.I remember a little old fella
    watching his lad use a crane to turn over a large pipe to weld the underside
    He took his pipe out and quietly said.What are you doing lad. Im turning this over to make welding easier and more accessable said he.
    Nay lad said the old fella they dont turn ships ovver,and quietly went back to
    welding

    Don't tell the old fella that during the week, the boys at work rescued a circumferential welder that had been lying in the weather at another manufacturer for years. I opened the control box, tipped the water out, gave it a few hours to dry out, plugged it in and it came up touch screen and all. It spins the pipe or whatever around and even holds the welding torch for you.... air rams position the tailstock live centre and move the torch into position all automatically..

    It's been a while but I have finally started on the wheeled legs for the lathe stand. This has been more important as I need to be able to move the lathe to the point in the garage where I have a 1-ton block and chain mount point. Under which I can easily lift the lathe, do some hole sealing and start some shimming to get the lathe dead flat on the stand.

    So here is what we have the draft design:
    [ame]https://www.youtube.com/watch?v=Zmjuntyp2ZQ[/ame]

    The resulting steel work in play. This is 80x80x6mm angle iron, really solid stuff. Today was about drilling holes and welding the other side of the hing on with a mix of TIG and stick welding. The TIG was all the outside fillets. The stick work was on the tight inside fillets where there wasn't enough room to get my #26 torch into.

    This is a rarely used but incredibly useful addition to a lathe stand. The original example I saw used a cheap hand winch to pull the two legs together. On mine, I got away with welding on a piece of 25 mm RHS on the bottom rail. I then turned down some 25mm steel rod so it fitted and I've been able to lever the wheels up into position just by stepping on the lever. But over time, I've needed some 25mm steel rod so the lever is shorter now so I'm not sure if it will work next time.... Personally, I don't think you need to tram the lathe on the stand when you have adjustable legs.

    I do agree though that every home needs a lifting point. I also used this to unload my lathe and mill

    I think i hvw some twist in the actual stand due this weld up that is the root cause. If so then adjusting on the legs might not cut it

    Don't look at my stand then. I'm sure mine is not perfect.... but its a pretty large and stiff lathe so it seems OK.

    I did some checks tonight using Rollie's Dad's method and get 0.135mm delta between the near and far end measurements on the horizontal. And 0.14mm on the vertical. So definitely some work to be done.

    Did a little more on the lathe wheeled legs tonight. Cutting slots in the uprights so they can be fitted for welding. Next need to drill holes for the mounting hinges and chamfer the ends of the legs for a tighter fit. Then use these as templates for the the second set of uprights. After that doing some cleaning and getting in there with the TIG on the easy to reach parts. Then blitzing the hard to reach seams with 3.2mm 6013 stingers.

    I did a little bit more on the lathe wheel legs and miss read my plans. This resulted in the holes being in the wrong spot on one of the legs. I did it correctly on the second leg. So how to fix things. Well I have TIG torch and I have seen guys built up holes with gas or TIG setups before. So why not give it a go?


    First off we plug the holes with mild steel filler.
    [​IMG]

    Then after cleaning things up and grinding back to a flat finish started drilling in the CORRECT spot.
    [​IMG]


    And the finished product. Old holes all filled in and new holes filled. I could have achieved a similar approach with an oxy/gas rig but TIG is what I have and wth the foot peddle its quite easy to control the heat going into the metal. The general approach was to close over the hole on one side then flip over, heat up the edges and fill in until its just a case of pouring metal into the centre of the hole.

    I got some progress after what felt like a marathon drilling effort and got the first of the the hinged wheel legs installed. This one is the tailstock end assembly. Things looking promising. I feel a movable lathe before the weekend is out.

    [​IMG]

    Okay this isn't a hinged leg. But it is a sample of the TIG welding I did this morning when putting the final leg together. I think I might have finally clicked with this TIG business. All the welds were similarly clean and consistent. :thumbup: th_wavwoohoo1

    Hey james, I just noticed you are using Google images to host your photos. Can you tell me how you do that? I've tried a few times without success.

    Nice welds by the way...

    It's a little bit of mucking about but google is far less likely to do a money grab (since their $$ still comes primarily from advertising). Anyway the basic process is as follows:

    [1] Set up google drive and activate this setting in the "General" settings area:
    Screen Shot 2017-07-30 at 10.01.20 AM.png

    [2] Now when you upload photos and put them inside this folder and setup what ever sub folder structure works for you. I don't use any auto upload from phone features so I am not sure how things would operate under that model.

    [3] When going to publish a photo you need to share it. I have been setting the sharing to "Anyone on the internet can find and view". Recent tests show that "Link only" sharing is sufficient. So you can utilize some of the UI short cuts to get that done faster.

    [4] Now open the picture from within the browser interface of Google Drive. You will get the "presentation" type of look. Something like this:
    Screen Shot 2017-07-30 at 10.08.56 AM.png
    It is worth noting you can of course adjust/set the sharing permissions from here. However if you want to share multiple images in one go selecting them and doing it from the file based interface is more efficient.

    [5] Right click on the picture and either "open in new tab" or "open in new window". You can now copy the url to the image in the new tab/window. This will be VERY long. Getting the link directly from the image without opening the image in a new tab/browser does not seem to get you a permanent link. So the result of doing this correctly will get you a link along the lines of:
    Using this permanent shared image link you can just use the "Insert Image" from the forum response toolbar to insert the image into posts.

    You can have the image scaled for you via the url. At the end of the url is where you can adjust the picture scaling:
    Adjust these [w]idth and [h]eight values to suit. The picture will be scaled to fit while still preserving its aspect ratio. I have been tending to use this setting:
    If you start reorganising your shared photos or change the sharing settings things will probably all break. But then it is free.

    Cheers,
    J.

    This will be a picture heavy post since its way easier to see than explain. And probably faster. Up shot is I now have a lathe on wheels. So I can move it under the block and chain lift point and take it on/off as/if needed.

    To start things off here is a close up of the construction of one frame. Not complex, not perfect but functional enough to do what I need.

    Now for all the gratuitous photos ...

    Thanks James, clearly my little chromebook can't handle your photo embedding methods so I'll try on my PC later. I have actually paid for Google Apps for the last 8 years or so. Therefore, it is a logical choice for a photobucket replacement when they boot me off. I've got 4000-5000 photos there and thousands of posts on forums around the world that are going to be broken.

    Your stand came up looking great!

    hi , would just like to say that this is one of the best posts so far . i have been following this post from the beginning and have learned more as it sort of swings from the start to more of everything about machining and machine setup . the more people contribute to this the better . i remember that you were thinking of ending this post as you said it looked to be getting to long , at the rate of responses i think it should go on until people stop responding . thanks for a great read .
