DIY CNC Router on Certiflat Welding Table Part 1: Introduction


All right, so what I’m gonna do with this is I’m going to be building the CNC table out of this and this is one of their 3×4, but what I’m going to do is I’m going to extend out here another foot and so I have four four foot by four foot capabilities and I’m going to see if certiflat will send me a one by one By four this one foot by four foot of this stuff that I can Mount down at ninety from from this surface, and then get one of their Fab wing and I can mount to that and extend it out another foot and So I’ll have capabilities of clamping stuff Off of this surface up and I could work on the end of stuff or I could use a full four by four even if I don’t If even if I don’t do that and I just get the whole gantry off of here I’ll still have a three foot by four foot surface and the axis The rate the rails and everything will be below of the surface of this, so I’ll still have all my function of this table I’m you can have big old blob of stuff hanging out over here So I got my linear rail I went with Import stuff from eBay, and these are the z-axis I have I have all the stuff These are 15 inches for z-axis. I went with the round rod For mostly for ease of use and Supposed to go with the you know that’s the square rail and stuff you got to be a little more dialed in and any fluctuations these these round rails kind of kind of help with with hope with Not being in line and whatnot these are the 16 millimeter rails. I was really thinking I was going to go with 20, but I ended up. I think the 16 will be just fine The x and y are 1,400 millimetres so 55 inches and That will give me 55 inches I walked you know 48 inches by 48 inches of travel and So now getting plenty of room access that I could build you know a longer You know bearing plate that can that can give me more more length that over that 48 inches and more stability The kit it was a kit with the to the z-axis and the ball screw and it had 2 for X and 2 for Y linear rails and I went ahead and got an extra set of 1,400 millimeter rails so I have Four total for what’s going to be the y-axis that way You know there’s a lot more stability there instead of just two there. I had a fab block version with the Perferated plate on the sides it would be really easy Easy project. I’m gonna do a little bit of welding to this table to to make this whole system work, but These so the spacing on these rails is 30 millimeters apart and You know the extruded aluminum You know would make stuff a lot easy with that. You know a lot easier with that t-slot extruded T’s a lot of stuff But they don’t make a lot of different Options for 30 millimeter spacing, and then you know 30 millimeters wouldn’t match up with your tooth your two inch spacing on this so if you get different rails that have different widths and somehow can configure an extruded aluminum that you could mount on the side and Extruded aluminum you know and then you should give a a bushing for this 5/8 down to down to whatever size hardware you’re going to use and You know being a complete bolt together system, but the way I’m doing it That would be a little bit of welding and that’d be no big deal at all So here’s how I’m doing me well X&Y Possibly the z-axis 1/2 inch by 6 inch aluminum plate and Bearing rails mounted to the plate and then I can Do you know take another 7″ section of that plate there for the? for the axis to roll on initially I was thinking of going with this I Believe they call it architectural C-channel so there’s not a big old flange in here and I can either go with Both bearings inferior, and then I can doing like a bellow in here with the lead screw in here, and it would protect it and There’s a lot of options with the C channel like you know I could go one here and one here And then take my excess C Channel and flip it around and the bearings would you know it would be a match set so that C. Channel could slide? Along here like this But I opted to go with this Mostly for ease of ease of assembly So this is an example of one of the benefits of using one of these tables for a CNC Machine is that you know you’ve got a lot of options for clamping and different different job setups and stuff these are build Pro item Magnetic these i believe are 1/2 13 thread You know with the magnet on them, and they go underneath there and you can put your bolts through and this is just from a set of T slot clamps for a milling machine and You know with a half 13 threaded stud, and you could you know Clank these down and you have really a rigid clamping ability using one of these fab square fixtures You know I can hold something up right and say I wanted to do something you know at the top of it You know like Say a wooden block or something I wanted to make a knob for the top of it or something like that You know I can use this plate here for holding that Some of the cons that I see of using one of these tables is You know if you were to crash the tool into the the surface of the table that would that would kind of suck But I don’t plan to do any real close stuff to the table surface itself I’ll put a put you know wood over underneath in between my work surface And or the you know the item in the work surface to the table One of the other cons is it’s not 100%. You know rigid. It’s got casters on and I might swap them out for feet or And then the other column obviously to is price you can you know build yourself a table for a lot less? But I think the the versatility of this table outweighs The downfall of it being being a pricey initial start up so that concludes part one and Please like and subscribe

  1. cool video:) Thanks. You might want to checkout this video, here is a link :https://www.youtube.com/watch?v=KnOdpZumCf4&t=5s I make some new products for welding tables like yours.

  2. For 30mm spacing on rectangular aluminum extrusion check parts HFS6-3060 or HFSP6-3060 (for a milled surface) at Misumi. Is the Certiflat a good table for a newbie TIG welder? Looks reasonably priced.

  3. I'm interested in where this series of videos will go. I'm thinking of trying to maybe at some point trying some kind of small CNC project made mostly with my surface grinder build thing. Not sure yet, but the seeds are there. 🙂

  4. Good project your are working on.
    So much for the Welding Table, LOL.

    This has changed things a bit.
    Converting the Welding Table to a CNC Table now.

    By the time i catch up to current time, from watching the older video,s first.
    You have most lightly sold this machine and gone onto something else.

    I am looking forward to watching this series of video,s.
    And look forward to catching up to current day.

    Thanks for the video.
    Regards Peter.
