10 x 5 foot plasma table build

[Robin Hewitt]

Whoa! You are starting by making a ramp? I can see you are going to fit right in here

more than that. I have to prepare to build the slide, hundreds of holes, so i dragged my bench pillar drill forwards to the front of the shed into the light, and am adding 2.5 feet to it, to make it floorstanding. All the elements have to be in place before i can start, in this case thats taking a while.

it's upping my machinery game though. I want a press brake!

the shed was a mess had to claw back space, ready to start new project.



a 10x5 table should just about fit in there. My landlord is knocking our house and building a new one, bigger. I told him about the machine and he said he might extend the shed while hes at it. I said to him, you dont have to do that, he said, I have the steel, I said, haha, go ahead so!

I have come up with a solution.

weld eggcup onto bottom of steel beam 1.

weld ball onto bottle jack.

fill eggcup with grease.

do this on 4 corners.


This is presuming that:

A.
The top surface of steel beam 1,
and the bottom surface of steel beam 2 are within a reasonable tolerance.


B.
The beams are straight. The shorter beams of the rectangle will have to be a very straight.

The weight of steel beam 2 will keep them orientated.
Now measure with spirit levels and adjust with bottle jacks. Repeat until correct.




When happy weld steel beam 3 into place.

Remove steel beam 1 as it was only ever a support.

Ned. Just thinking do you really need a roller table as it will take a lot of room how about something more simple along the lines of http://www.toolstation.com/shop/p431...Cnup-1x8wBEiQA

Especially if you are just using it to build the CNC

Hiya Clive,

yah thats a notion allright! seems much easier. However I've wanted this setup for a while now so am happy to proceed. I'll use it for a lot more than just the plasma table, and building it square a good trial run before the plasma table.

The pic of the shed above, im getting rid of all the shelving on the left side of the pic. I'm putting the roller table on castors so it will slide in along the side when not in use, for longer lengths of steel I'll put it out.

okay hello again everyone.

I totally cheated and bouhgt a fully functioning 8x4 router table. However! The table itself isnt suitable, so I'm building an entitely new table, so this is still a build log.

Table can bee seen here. It ran like crap when i got it but replaced some of the bearings and now its pretty smooth

Warwick I'm going one bigger than 80mm and building it from 100x100x6.5 box iron, this fugger will not flex.
Also it doesn't have to be elaborate, since this metal is just hugely strong. I intend this to be the shape, just very very very simple



So I'm going to transplant the Y axis rails, the Y axis ballscrew and then the gantry onto the new table.



My current notion to chew over is the Z axis. I'm going to cut the router mount off the carriage and bolt on a plate. Then I have to think about what lifter to use.



If anyone has suggestions for a lifter and THC they like im all ears. Going to be using a machine torch and hypertherm powermax 45.
