Making Bar Signs! #71 - Brisbane, Australia

Hi,

Quick introduction, as I have got so much reading to do!!
I am totally new to this sort of thing and come from a Shopfitting Joinery background but with no CNC experience. I am looking forward to the journey, just need to find my way before taking my first steps.
Looking to mainly wood carving and acrylic fabrication, anyway enough for now and feel free to throw any advice this way.

Cheers
Tony.

Tony,

Welcome.

Print off the plans and start reading the threads. You will learn as you read and you need the plans for reference.

Good luck.

Hi,

Plans were the first thing I downloaded reading some of the threads now on some of the Australian builds that are currently underway, just so much to take in, but thoroughly enjoying the experience.

Cheers
Tony.

Control Panel

Hi,

Purchased my control panel last night, which is my first purchase towards getting my Mechmate underway.
Such a great buy I could not resist, guess that's me hooked now!! lol.



Screen is a touch screen and after loading Mach3 onto the computer last night all worked a treat. There is also heaps of room in the metal cabinet for all the other electronic equipment so this should do the job well.



Guess I need to start ordering some laser cut parts, steel and electronic equipment now so I can put this control panel to some good use.

Cheers
Tony.

Hi,

My MM is now underway with some good news from Rick, my laser cut parts are underway.
I have also decided that my MM will be made to take a 2440mm x 1220mm sheet size, so now I just have to work out what size/length all my steel needs to be.
I will also be looking to start purchasing Motors, Gecko's, BOB, and still looking at spindle/router options.

Cheers
Tony

Hi,

So with regards to the lengths and widths of the steel I will be using on the table, do I use the drawings and just add the X and Y size of my sheet to the additional sizes noted on the drawings, or is there someone that has already worked out all the metal sizes based on a sheet size of 2440mm x 1220mm that can help me out ??

Thanks for any help and advice.

Cheers
Tony.

Yes, that is the intention, and it seems to work.

Thanks Gerald,

I just wanted to be sure as I have never taken on a project of this nature let alone steel work before.
I guess my next step would be to workout a cutting list for each of the steel types, so that I know how many meters of each I need, then source what is available locally.
If anyone in Aus has already done a cutting list for the table based on the sheet size I am working too, please feel free to chip in.

Cheers
Tony.

Tony (AuS MaDDoG) & Paul (Skippy),
This post maybe just too slow, but I need to ask the question, I'm a "Mexican" from down south (Melbourne) seeking assistance from a bender (banana) in tracking down one of those free standing computer consuls, either type will do.
Can either of you point me in the right direction, hopefully in Melbourne, as the freight from Brisbane would possibly double the cost, I would appreciate your help.
Thank you and Regards
David T.

Update!!

My friend Paul (Skippy) and I are both in the planning and purchasing stages of our MM build.
We both have our control panels, including touch screens, Paul has his laser cut and bent parts and I am waiting on mine arriving from Rick. Paul recently ordered our motors which should arrive within the next couple of weeks.
In the meantime not being familiar with what is available in steel I have found the following sections appear to be available, however I am not sure if it is too heavy or not, so any help would be appreciated as I do not want to over or under do things.
Once I have this finalised I will draw the table up in cad and produce my cutting list.

Steel & Spec's
Table legs to be 75 x 75 x 6mm Box 6 off 7.32 Kg/m
Rails & Bracing to be 50 x 50 x 6mm Box 12.0 Kg/m
Y cross bearers to be 75 x 40mm Channel 6.1mm Flange & 3.8mm web 5.92 Kg/m
Main Longitudnal Beams 200 x 75mm Channel 12mm Flange & 6mm web 22.9 Kg/m
X and Y rail angles 65 x 50 x 6mm 5.16 Kg/m
Y axis gantry rails 100 x 50mm x 2mm Box 4.5 Kg/m

If anyone can see any issues with the above please let me know asap.

Cheers
Tony.

Hey Tony,
Thats list of steel sections looks very close to what i used except you are going for a heavier wall than me.
The only differences to what i used are:
70x70x3 (legs) (may have been 75x75x3?)
50x50x2.5 (bracing)
180x75 PFC for the (main rails) (11mm flange, 6mm web, 20.9kg/m)

You list looks good though i don't think you will need 6mm wall thickness for the leags and bracing. Mine is rock solid and weighs enough as it is!

Those legs and bracing will be okay at 4mm wall thickness.

are you implying i went too thin Gerald? I think 3mm is plenty...

A guy who was thinking of 6mm won't half it to 3. Then 4mm sounds like a nice number without losing face.

Thanks for the responses, much appreciated!!
Like I said I have no idea when it comes to steel or sizing, I just read a couple of times heavier appeared to be better
The steel I sourced mainly to get the sizes and to seek your recommendations as too whether it was too heavy or not??
If 3mm thick wall on the legs and bracing will do the job, and do it well, then 3mm it is!! as it will probably save us a few $$ as well as my back which is not as good as it used to be

Thanks for the info guys!! now to start my drawings and cutting list / takeoffs.

Cheers
Tony.

I hear you Gerald, loud and clear!

Just to prove i didn't wing it, Beam stiffness is a function of elastic modulus and cross section moment of inertia. Given we are considering the same material it comes down to cross section.

Legs as per Drg 10 10 332
75x40 parallel flange channel
Ixx 6.83x10E-7m^4
Iyy 1.20x10E-7m^4

compared to 75x75x3
Ixx=Iyy=7.16x10E-7m^4

Long Braces as per drg 10 10 312
50x4 Circular hollow section
Ixx=Iyy 1.54x10E-7m^4

compared to 50x50x3
Ixx=Iyy 1.95x10E-7m^4

So the 3mm wall should still be stiffer than the drawings require

Matt, your table will be good. Realise that we are not looking for bending stiffness of the legs and associated parts, so the I factors are not really relevant there. We are looking mainly for plain old mass. But your masses also calculate out okay.

Rick's laser cut parts look ready good, I see that he packed the same way that he sent them to me Which was great. Looks like that we got the new roller skate version, I might need to use yours instead on mine.

Haha!!

No worries Paul, I'm sure it will do the job for the both of us!! I should be able to borrow one of those Makita metal saws for cutting down the angle rails too, which should help speed the machining process and make the grinding of the V process much easier.

Cheers
Tony.

Hi All,

Update:- Our motors have arrived in Aus from Canada with one box of 5 recieved, and the other box of 5 in customs

I have done this drawing just to get some idea as too where I am heading with the table length, and thought I would post it up for comment, and for my peace of mind that it is right.

As said before the sheet size I am planning to work around is 2440mm x 1220mm. I think I have the correct sizes for the length of the table and once I am sure this is right I will work on doing a drawing for the width.



Look forward to your comments.

Cheers
Tony.

Tony, that looks right, with your "home" end at the left.

I presume that you will be using a cable chain for the X? We use a harness/umbilical hanging from under the table to the end of the gantry, but then we need a space where you have the center leg.
