Well on this aspect, I came up with the idea that I can make one myself for close to if not under half of what major brand tables manufacturers are asking, and I can make mine however I want it to be. So, I needed some steel one day for an actual paying job, and since I had been past the research phase of what other manufacturers wanted for theirs, and moved onto getting prices for what steel yards wanted for the materials for me to build mine, I not only came home with the steel for the paying job, but also the steel for building this table.

Now I don't want to get into a pissing match over a automotive manufacturer, but I mean I had around 1500 lbs in this 2010 Ford F-150. I got a Picture of the load and how I secured it, and then of the measurement of the suspension with the load on it, haven't gotten around to measuring no load suspension height, but I wasn't on the bump stops yet.
So one of the first things I do is send the picture of loaded truck to my brother, since he is a Ford fan as well, but I sent it with the message about it being weight lifting, to which he replied "It doesn't count if a fork truck put it in.". Well I say good thing it was an overhead bridge crane then. But regardless I have to take it out by hand one stick at a time since my gantry crane was already occupied with another project and it wasn't worth moving it for this bit of work. I tell this story, because I was dumb enough to agree to do a Tough Mudder event with him and I am not a runner, I figure I should stretch Liberally to limber up and then work on some upper body and core strength, so this counts. When I die at the Mudder event, and yes they make you sign a death waiver, you readers won't have to read this anymore and will be either in praise or disappointment since this is only the second post.

Okay, back from that tangent or digression, Since I was handling this material, I got the L3 x 1/4" angle which was cut to 12' ish and 8' ish lengths (Another tangent there.) out of the truck no problem one at a time. Then I got to the again 12' ish and 8' ish lengths of 1/2" x 4" flat bar, it was a little heavy for one little guy such as myself. I managed to do it, but I decided to cut it down to the final dimensions as I got it out of the truck first thing. 

This is where the tangent story on lengths comes in. If you have ever bought metal in standard lengths you know this, but for those readers who haven't, a 20' piece is normally 2-4" longer. So I told the guy that it would be fine if they cut it on an abrasive saw (Wider kerf and rougher cut with sharp burr left behind) versus their Horizontal band saw (narrower kerf, and little to no finishing needed to cut end) so that I could get it done that day since I was there and the band saw had a day or two line up on it, so long as they cut it accordingly so that I can get 2 - 4' lengths out of the 8' side and 3 - 4' lengths out of the 12' side. I didn't think that I would need to check this as I had hoped that they could figure this out. I get home and measure, I got 12'-4" and 7'-8" on all of the angle and flat bar. So with this the dimensions of my table are now changed from 48" wide to 46" wide. This reinforces the idea that in the trades, training day one should be how to read a tape measure. And if you are confused and haven't asked someone else by now about the word "kerf", it is the width of material that is consumed by the width of the cutting method be it a saw blade, a abrasive saw blade, a oxy/fuel or a plasma torch, etc.

Now then as I was saying, I was cutting the flat bar to length as I pulled them out of the truck, I used my little Harbor Freight 4x6 Horizontal/Vertical Band Saw for this. The blade is getting worn, but still chugging along with only one missing tooth to this point. (Different blade than OEM, this is a Super Cut 10-14 Pitch Bi-Metal Blade.) In the picture of the material stacked after cutting you can see the difference in the cut of the saw they used and the saw I used. My cuts are the shiny ones with lines and theirs is the burnt looking ones with curves.
Finally I got the material sorted out, got the slats for the top cut to what they will need to be, now if only I knew what was missing. This may be a controversial decision, but I like the idea of being able to move things around in the shop, lots of fabricators out there like myself feel that a table shouldn't be mobile as you will inevitably be leaning on it to get yourself comfortable and stable to make a good weld. After all one of the first things they teach you is to go through the motions of the weld and get comfortable before you do it. That being said I feel like If I want I can always immobilize an object with wheel chocks or something else, but if it don't have casters to begin with, it isn't moving. So I got some casters, found what I thought to be an alright price of $80 or all four of them shipped, they are 5" x 2" have three different grease zerks each and lots of bearings, oh and rated for 1000 lbs each. Now with some crummy casters I have no problem with welding them to the object, but with nice ones that you want to last for a while and then when needed be able to replace without damaging your table, I choose the bolting method. Now $30 of hardware later for the 16 bolts, 32 flat washers, 16, spring washers, and 16 nuts, all for 3/8" Grade 8 I might add, I thought welding wasn't too bad of an idea.... No I got the hardware.
I think for Part 1 I will call it complete. I seem to unknowingly have kept it centered around material acquisitions for the table and no actual fabrications as of yet. So Part 2 will be more on fabrication, Not sure how far I will get into it, but I want to put in lots more detail on the projects in the blog than I do in the heavily edited YouTube videos, So if you are looking for a detailed description of the build, here is a good place to be. And once this is all complete, I will transfer it over to the Fabrication forum shopfloortalk.com and there you will see the feedback from people far better at this stuff than me. However if all you enjoy is a high level overview of what happens, As I get to it I recommend watching the YouTube channel for the fabrication project videos.

Thanks for reading through this, and look for Part 2 to follow soon.

<![CDATA[Introduction - The Full Thing]]>Sat, 21 Mar 2015 03:07:53 GMThttp://www.dfmmc.com/blog/introduction-the-full-thingOkay, lets start off with, I don't know why I am choosing to start a blog in the first place. I wouldn't think that I need one to share my creations with you guys, with my YouTube channel. But I guess I am making a transition in my delivery method as I become more heavily involved with the online forum "shopfloortalk.com" of which I've been a member of since 2007. Thing about that forum is that we all love seeing other peoples projects and sharing knowledge with each other, and above all else pictures of the projects. Great thing about that forum is that they still cater to those who have slow Internet speeds. So in order to appease people like this, and possibly to provide more detail about what even I possibly didn't know I was thinking at the time of making something, I will try to keep this blog going and hope that it is like most books vs the movies, That it will have more detail for those wondering. 

On a side note, Hopefully this delivery style will sharpen my understanding of the very message that I am trying to convey, and hopefully I will become a better writer for the forums.

Thank you for taking your time to read through this introduction and any future posts that I hope intrigue and pass along knowledge to you, the reader.]]>
