Some more progress done.

 

First pic is the plasma clamped to the frame with "U" clamps.

Next, a close-up of the screw thread for height adjustment (which still has to be done).

 

DSCF0427.JPG

 

Next, a close-up of the remote switch to keep the plasma running.  Just to screw the bolt down onto the button which also enables me to use both hands for tracing around patterns etc.  As the height is adjusted for the torch, I can adjust the remote switch with it.

And last pic, the setup for the counter weight at the back.  Am able to put more on if required.

All I have to do now is finish off the height adjustment thread and do some practice runs for speeds and amperage settings for each thickness of plate used.  Plus I will try and upload a short video of it running.

Done some more work to my cutter table.  Here is a pic of the letter "M" which has been cut.

And here is a video of me cutting it.

 

 

I still have to also set up an oxy cutter for the table as well.  I will upload that and post pics when I have done it.

Wow! It appears to work great! What's your first project going to be?

No "project" as such but I will be cutting some parts for 2 jobs I have to do.  The first is some bracing plates for a forklift extensions and some mounting plates for a rear bumper bar.

 

Thank you for your comments Tyler.

Started to add oxy to my profile cutter.  The first pic is of the oxy cutter attached to the frame.

 

DSCF0432.JPG

 

The next pic is the back of it showing how it is attached for raising and lowering for different plate thickness.

 

DSCF0433.JPG

 

Next is the whole thing connected to my oxy/accet bottles.

 

DSCF0434.JPG

 

And lastly, a close up shot of the oxy cutter connection.  What I am going to use for the remote switch is a "U" clamp with 4 nuts attached holding the clamp plate.  All I have to do is lower it to hold the lever in place while I am cutting, then when I am finished just lift it off.

 

DSCF0435.JPG

 

I will post another pic of that tomorrow.

Back again and here is a pic of the "U" clamp holding the oxy lever down for cutting.

 

DSCF0436.JPG

 

Then just slide it off when finished.

Next is to mount this motor for the magnetic tracer.  I will use the same setup using a small square tube with a bigger 1 over the top and a bolt with lever to adjust height as I have done with the plasma and oxy mounts.

More pics to come soon…just about finished whole profile cutter project.

It looks like you've designed the thing so that changing cutters is easy – great idea! What a cool project.

Thank you Tyler for your comments.  I have done so it is easy and quick to change between plasma and oxy cutting…just a couple of minutes.  I have been very happy with the result so far and its not long now before it is finished.  The tracer "magnets" will be here in the next 7 days so I can finish off the tracer part.  Then it will be all automatic cutting.

More pics to come as soon as I can.

I must confess, I haven't quite figured out how the tracer magnets are going to work. Another video when you get them fitted would be excellent!

Any thoughts on drawing up your project?

If you can imagine this…a small magnet(s) which is inside a small shaft (1/4 inch thick) on the outside of that shaft it is knurled.  The shaft is connected to a motor which turns  at a rate set by the operator or a slow paced motor (7.5rpm).  The tracer in turns moves around a metal template of the desired shape to be cut.  Please refer to the diagram below.

Here is a video which shows how it works…not my video.

 

 

Hope this helps.
