So yea. These were made to specifcation using the DXF file's that come with the MM plans. Imperial thicknesses and metric dimensions. I have to make tiny alteration here and there so I could get the parts to bend within the software. No biggy. I am going to start modeling the rest of the components now. I think all the remaining components are actually made by the MM builder. After that I can finally assemble.

[cvriv.charles]

Can a moderator please delete my last worklog I created please? I'd post my MM build in that thread but I want to keep everything nice and neat. Less confusion that way. Thanks.

Here's an update. According to the plans but with a few changes. Check it out.

Here's how I would like my table to be. The plans call for the 8 cross beams(1010302SB) to be welded to the x beams(1010322SA) because it's permanent. That way you dont have to worry about the able going out of square. Which is good because thats one less thing to worry about. BUT! like some,... I need to be able to dismantle this machine for transport. What you see in the image below weighs about 650lbs. Thats according to Inventor. AND! Thats only what you see! LOL.


So instead of welding these 8 beams I am going to do what many others are doing. Im going to bolt them.


To keep help keep the table square,... I and going to weld a support bar across the ends of the beams, in sets of 4. These support bars will hold the cross beams together so that they are square. When the x beams are bolted to them they will be square with each other. Once the table surface is bolted down to the cross beams, it will help hold the table square too. Plus the legs of the table will help to hold the table square also.


Forgive my Inventor rendering abilites,... im still trying to figure that out. In this pic you can see the inventor welds for the end plate(1010324GA) for the x beam(1010322SA).


Here's the bolts that will hold the x beam to the cross beams. 16 x 3/8"-16 heavy hex bolts. I have to use beveled washer because the steel channel has an internal taper. It very dark. Sorry.


Im using 3/8"-16 socket head bolts for the table. These bolts will screw directly into the the cross beams for ease of removal.


See Still kind of dark.


Here's the underside. You can see the two sections of cross beams. Kind of like pallets. Really heavy pallets.


Here they are alone.


I dont want to weld to much because I dont want to deform the metal to much. I think i'll be fine with this. The very end with the flat side facing out gets welded all around the channels shape. The remaining 3 only get a top and bottom weld. That should be good. It's not like those support bars are going to be taking on a load.


And thats it for now


Now this isn't my final size. I will know for sure its final size once I build the gantry.

[Kipper]

Will you be actually building something or is it an exercise in drawing....and will it be "Elite"?

[harryn]

The Mechmate is a nice machine.

I was not confident that my skills and budget could build up those parts from scratch so I ended up on a different path.

Are you planning a build / buy combo strategy ?

[cvriv.charles]

Yes. I plan on actually building this. I am planning and learning how first so I actually go ahead and build it I dont end up screwing up costing me more money.

I actually see myself building 2 of these. But the second wont be until down the road. After this mahcine I would like to "TRY" and build a laser using the MM concept. If building a laser is TOOOOO expensive,... I'll settle for a plasma cutter.

As for the "Elite" thing,... thats just a name I have.

[Hirudin]

The drawings are very cool but to me they also look very complicated. Are they pieces that you're going to buy or build?

If you are going to build them I am curious if you have experience bending metal like that. I know that I certainly don't, but the little bit I've seen/done makes it seem very difficult; 'specially when accuracy is so important.

[cvriv.charles]

There is a guy over at the MM forums that sells these parts in kits. They come cut and bent for you already. I plan on purchasing a kit.

If I had to do it myself I would most definitely buy what I need to get the job done. When your working with 1/4" steel, there only so many ways something like this can be done.

As for the drawings being complicated,... they really arent. Atleast to me they aren't. The whole reason for these drawings it to test to see whether or not I understand the designers drawings. That and to determine exactly what is is that I need. Without these drawing I would most certainly end up buying to much of something or not enough at all. This is what cad is good for. Saving money.

[Hirudin]

Oh sorry, I should have said the drawings are cool but the parts look complicated (as in: not easy to produce). But if you're not making them yourself it doesn't matter.

[cvriv.charles]

Oh yea definitely not an easy task to do on your own especially if you dont have the right equipment. I would suggest having them made for you. Joe from MM forums sells the kits for 450ish and about 60+ to ship. All the parts cut and bent. Ready to go. Thats not bad at all in my opinion. For every one of these machines I build I plan on doing just that. Or atleast until I build my own laser Or plasma cutter is lasers are stupid expensive to build.

Sorry for the delay. I've been stupid busy. Working. Sleeping. Buying a house. I have a ton of stuff going on. Didn't really get much drawing done but this is what I do have done,...

I did a few things actually. I remade the spoil board because I just wasn't understanding how the spoil board works. There the bottom layer of the spoil board called the support board that gets bolted to the table. Then there are spoil layers that get glued to the support board. You pretty much embed the bolts within the layers. You use nuts on the underside of the table to hold the support board down. Now, you use the router to surface that spoil board so its clean and square to the router bit. Once the surface of the spoil board is destroyed enough, thats when you surface the spoil board with the router again. once you cut down far enough you then go ahead and glue on another layer Cool right? Anyways. I had drawm up the legs and supports for the table too. I totally forgot to take a pic of it but the way I have it, the entire machine disassembles into a few pieces. Well more than a few but not as many as there could of been. The two largest pieces of the machine are the sides. A side is mostly welded together with few things bolted to it. The side are held together with table cross supports and leg supports. Not including the gantry,... thats a total of 10 pieces right. Atleast right now. The sides are way heavy. But I can move them.


All the bolts are missing. These are test fit pics. I'm working on the x rails and gantry now. Everything will be fine tuned in the end. I will literally build my machine according to this model.


Been practicing my welding skills. My girlfriend bought me a 110V 140amp Lincoln MIG for xmas. Seeing that there is a god amount of welding involoved with the mechmate router,... im practicing now. I only have like 2 hours of practice under my belt. LOL. But I'm doing good! I have a good grasp on flux-core welding with a MIG welder. In this pic I'm set up to make a weld. I'll first tack weld that in place and then complete the weld with two hands. I'm ok with one hand but I perfer two when I can. This is going to be a strength test because many dont believe that a small 110V welder can weld 1/4" steel. Going to prove them wrong!


Sloppy. It's been several days since my last 1 hour practice session. LOL. I have to stop welding to the ends. I'm melting the ends away.


I'm going to do a 3" run across this section here. I have it already tack welded in place. I'm at it with the wire speed at 1.5 here. I prefer 1. Better penetration. But you have to go slower through to fill in the weld.


Done. This is pretty ok. The brown stuff is slag from the flux-core wire.


Just did the other side with the wire speed at 1. You see how the weld is concaved? I think they call it undercut. Its from not filling in the weld aka slow wire speed. I used a wire speed of 1 which is ok but I went to fast. Didnt give the machine enough time to fill it in. This has good penetration though. Everything was melted under that bead.


This "thing" your looking at is a wire speed setting of 2. The inside panel of the welded said I should be using a wire speed setting of 2.5 for 1/4". I dont get it. It obviously doesnt work. Not enough heat for that wire speed. There was tons of kick back, respark, slatter,.... just ewww. You see how the weld bead is large? Thats from not having enough heat. The bead grows quick because theres just enough heat to melt the wire onto itself. Not enough to heat the work too. Poor penetration.


This is a wire speed of 1. This time I went slower. The beads looks more like a chamfer now as oppose to a concave. I really should be using a wire speed of about 1.5. You want to build up but I like this weld. It's clean and tight.


Here's the ugly weld with some of the slag removed. There's still some left. It's actually looks like melted metal. It all has to be removed before painting. Best to grind some of the weld away to be sure the slag is gone. Or if you have a sand blaster, which I dont.


My pretty weld. The slag is on the edge of the bead.


Tried getting a cross cut to see how far I penetrated but that obviously didnt work. I wonder how they get cross cuts?!?! You see the difference in bead size? Although the bigger bead looks stronger,... ?I have my money on the smaller beads. I know I penetrated far.


Here's a crappy 1.5 wire speed. I was playing around to see what would happen if you moved to fast or two slow. Just want edo t see what would happen. I was moving a bit fast in this pic.


Moving fast here too.


Time for the strength test. Did the 110V welder do the job most think is not likely? We'll see. This is the first weldment I did. I did it with a wire speed of 1 with the amperage maxed. I went kind of quick with this weld. Not 100% sure it will hold. maybe 90% sure. I had a weld kind of like this break the last time I tried. But I was super new at that point.


So I did another one with the same settings except this time I went slow allowing the heat to seriously soak into the metal creating that permanent bond I am looking for. I stayed clear from the edges too. Still sloppy.


THE RESULTS ARE IN! It's conclusive! LOL.That is ONE piece of metal you see there, not 4.


This side I used a big thing of pliers on the top of the flange and just muscled it down. It work but I though that wasn't convincing enough so I broke out the hame and beat the S@#$ out o fthe other side.


Yeeeeea. This isn't going to break.


Awwww. Thats thin sheeting. With setting maxed,... I can just blow holes through this sheet like a knife through paper.


Now,... time for house pics. This is going to be my new home. It's not ours just yet but we are closing in the next 2 weeks so yea it's pretty much ours. But im not going to hold my breath until they hand me the keys. We got 1.25 acres.


Big ole' hot tub in a gazebo in the front yard.


We need a mower. A big one. one I can ride.


Side of the house.


My girl makin sure everyone is working hard. LOL.


My back yard. Awesomeness!


The kitchen. Which we are going to like work on. We have a lot to do.


Previous owner a modder?!?! Maybe


And the best part,...


A big garage.


A place just for me so I can do my work uninterupted!


HOT! Oh yea, of course, I mean you Christy,...


The garage has electricity and is heated. Or atleast will be as soon as I hook that antique in the back.


The clean room.


This is where I will do a lot of my clean work such as light fabrication, assembling, packaging, computing, etc. The other room will be where all the dirty work happens. I actually want to move the furnace into this room. The dirty room will be messed with dust from wood, acrylic, metal. I dont want it to funk up the furnace.


Yes. The clean room. Well look at that. Theres an upstairs to this place.


Oh yea. Storage. I might even put a mechmate router up here. Maybe two. I dont know. The machines are very heavy. Maybe if I brace the ceiling some more from downstairs. I want all my fire starting machines down stairs on the concrete. I dont know. We'll see.


Anyways,... I'll start posting real work very soon. I am hoping to start the router fairly soon and definitely start working on blackout right away. As soon as I move in and get all my stuff out of storage. Patience.

The cut is too rough to see the finer details. Sand it smooth on a disk sander, then sand it with 400 to 600 grit sand paper. You will then see the color changes in the metal, gas pockets, and any small fissures in the joint.
