If I didn't have to ultimately move my table out through a narrow door, a ferrocement water table for a plasma machine might make sense if one were short on money and materials, but not time.

After reviewing one thread here with a fellow stacking his 3x3 to get 3x6, it dawned on me I could lay the 2x4s horizontal with a 2x2 spacer. That would end up being 4x6 I beam with reasonable...

My plans for a table originally had just one side of the gantry double trucked on one CRS rail. The other side would have just one truck or carriage for elevation control, no side tracking, in or...

A 3" x 6" 'solid' 8020 rectangle will have more a lot more resistance to bending, torque and vibration than my 6x4 'L' made from 2x4 8020. I do have some extra 2x2 pieces but not full length, that...

Seeing so many combination machines I just had to modify my 5' x 10' plasma table to do some routing. One design by PlasmaRouter appears to have a 6-8" tall gantry beam, not sure how deep.

I was wondering about the details on the MechMate, specifically the rails X and Y. The Z axis also. Many of these sites only give a grainy small pic of their machine with no specifics. I will not...

Hi synd00d,

You need to go to Daniel Gentiles home page and down load the 18 page Krusty spring helve hammer plans for free!

HI massajamesb,

Out of your price range??? Many tables that function much like this are made with 608 bearings and micro timing belt drive. That fellow in France has the best CNC table...

Just how much flow and aeration is needed to keep hydrogen accumulation in a water table from building up to explosion levels?

Is it so touchy that the injected load of hydrogen needs to be...

HI Graybeard,

Thanks for the additional information on your water table. I will be cutting aluminum so sodium bicarbonate is out for a rust solution on steel.
Have heard of the explosion...

Perhaps Dale was thinking of the track and boom CNC torch cutters that are very prevalent in china.

They are indeed very simple and portable. You can lay down extra...

Hi Jack C.,

I had not even even considered head pressure, but when the table and tank are connected for drainage the height of the water column is 2.5', just a bit over 1 psi. You need to...

Someone here mentioned Company made water tables used air pressure to transfer the water from the tanks to the table. After viewing one water table and its fast water level adjustment, I presumed...

Hi Tom C.,

Thanks for the recommendation on water table depth (4"-6"). I would like to shoot for the 4" depth as a feasible depth for the installation of slat holders. Drainage would...

Hi Jack C.,

Your Post on your customers use of only 2" of water with light metals is very promising. That would reduce the number of supports I would need to setup and take down with every use...

Hi Dale,

I can appreciate that with only a 1/4" of water, blown away from the cut zone, it will allow a certain percentage of blow back from plasma cutting. Having spent an overnighter in the...

Hi Dale,

Perhaps I was not descriptive enough. I was curious about the depth of water UNDER the sheet. Tom and others have noted that an ordinary plasma setup can only handle a easily blow...

RIGHT FORUM THIS TIME!

Looked at Graybeards pics of his water table on Yahoo. Didn't find much info on submerged cutting there or here. Lots of dead ends hits on cnczone, the search words bring...

3hp of exhaugst would make for a cold or hot and muggy shop for some people.

Are there any options for recirculation and filtration using less hp and blanking off open areas of the bed?

I...

I've seen a few torch holder/actuators and a perhaps a few more spindel Z-axis units on this website. Stored all the interesting ones in my files, but not necessarily by that feature, just the guys...

Looking at this SL100 "1torch" machine torch from thermal dynamics at the welding supplier this morning. I note they are half the price of the Hypertherm machine torch, possibly to encourage people...

Thanks for the informative reply Tom.

Thanks much Tom, I'll be buying one soon.

In speaking with my hypertherm dealer, one of the salesman mentioned that speeds and power were really the things that will determine the amount or lack of dross on cuts. That contradicted what...

Talked with my Hypertherm dealers mechanic who I have know for some time and he had just replaced a powermax 1100 with a Powermax 1650 G3 on an older commercial table they had sold. Their Salesman...

There is not a lot of comparative information on the finecut tips vs HD torches.
They do mention near dross free with the finecut, but for what ends? No Photos that you can inspect or specs...

Thanks for all the tips. Looks like sticking to proven stepper techniques and readily available boards for my first table will make things less problematic.

That Rogers board looks like my...

Your thoughts are my thoughts also on reading about hydef. Didn't see anything about the powersupply mentioned. Of course they use 3ph, but I presume the 1ph supplies are well damped. Obviously...

Has anyone used a belt and pinion drive like Carlson on their plotters? No loop over of the belt. It appears to be held on it's end and most likely glued to it's substrate along the way for...
