Thanks for the replies.
Nice control cabinet, luv the keyboard.
That is the keyboard I had on the wee lathe, the only pain about it is it has keys for WWW. And Smily faces, must have come out of an Internet Cafe or something.
Is that a water table tray, my concern is that it will not work for downdraft??
It is just a tray, no water. Tell me more about the best way to do for downdraught as I know absolutely nothing about it.
I was planning on having a fan in a box below and have some form of seal when the table in normal position.
I would also fit some hard stops so that the tilting system can jam solidly against them to remove any twist in the tilting frame.
The Y axis will be made of 100mm x 100mm x 6mm steel box joined with 100mm x 100mm x 8mm angle so I dont think it is going to twist much but it will be against an angle at the rear and I will have bottle screws at the front to tension it. If I do run into issues then I can always put in support legs.
2p suggestion.... have you thought about offseting your two Y axis so that you get more travel use of your table?
As its drawn, offset toward the back of the machine, given as its shown your torch will be on the front, hence can reach the front rail of your table at the front but may be 100mm from the back of the table?
Not 100% sure what you are meaning but I think I have what you are saying, see first pic.
Is the rear of the table not going to catch on the frame (around where the rails are) when you tip it up, so you may need to offset the table pivot point further forward?
As you can see on the vid there is clearance, I have made the frame transparent in the vid. The outer frame was originally going to be 100mm Alu box so that is why it shows bigger than the back rail.

As you should see in the vid it will come against angle and although not drawn I will have bottle screws to tension down the front, and as I mentioned to Dave legs will be fitted if required.
The central rail may also become consumable (the central slat support rail, as the cutting power of your torch may exceed the offset depth of where the rail starts).... maybe using angle iron will improve your build time for the slats (but the cost would go up) I'll post a picture of my slats later may help someone out for an idea in the future.
I have a small gap from the top of the slats to the top of the angle supports, see second pic, it is 5mm, do you think I should increase that?
Pic below of the inside of the container and the progress so far on the frame. To the right you should also just about be able to make out the profile rails I snagged from a friend, they are not perfect condition but should be fine for a plasma (I hope anyway
) They are 35mm wide, so quite substantial and bloody heavy.
The Gantry I will make from 4” x 4” x 1/4” 6082t alu, hopefully it will be rigid enough, if not then I can double up on it.
