Are you asking any questions?
I'm going to build 4'x 10' cnc router. I want to make the table height adjustable. The table needs to be 6' long most of the time so the end has to fold down. And I would like to have a 12" X 48" vise on one end. I'm new to this so go easy on me.
Thanks

I'm going to cut the table out of aluminum to make the adjustable table 4' X 5' so I can get the size to start cutting my stainless tubing. I will have to make a jig to drill screw spline in aluminum then will weld joint after bolting. At this time I' m not into it far enough to ask questions but I'm sure it won't be long.
Thanks
Did you win the lottery or do you have another reason to use stainless steel for the machine structure? I hope you realize that working with stainless is very difficult compared to regular structural steel.
Could you share a drawing showing how the end of the table is somehow going to be able to fold out of the way and extend when needed? I'm having a hard time picturing this, given that none of the machines I've ever seen could do it.

I'm using stainless from the salvage equipment at the company I worked at. We only used stainless so I have been saving materials for about three years before I retired. When they scraped equipment I salvage as much as I could get my hands on. I was able to cut and build the 8020 aluminum table now I need to start the adjustable legs. I have a 10' stainless threaded shaft from one of are freezers that was damaged but will work fine for adjustable legs. At this time I don't have any drawings but I will try and post some pictures if I can figure out how to do it.
Thanks
I found 12v gear motor and power supply on eBay to drive my legs up and down. I also picked up 24" absolute scale so I can monitor height when running up and down. I have used v bearings and rails from our robot rebuilds that I will use for vertical guides. I want to make wheels to roll around in shop and screw down legs when it's parked. I will be doing a lot of lathe work today on leg screws and screw down stops hope to have a picture or two tonight.
Thanks
Are you driving the screws with roller chain?

Yes the vise screws I'm using #25 and table #35 roller chain.
Thanks
You've got to get the pictures rotated. Looks cool, but very hard to look at.

I'm using my IPad to take the pictures and they look fine when I view them. I'll try rotating when I take them and see if that works. When you click on icon at the bottom of the post window they are right side up. Guess that's why I never got past the third grade.
I finished bearing guides for the table and my linear actuators arrive so I can work on table extention today. Then I will cover top with aluminum extrusions. The table will lower about 12" but I'm not sure if the play in the leg screws will be a problem. I'm hoping the weight of the table will hold it down or I'll have to deal with that.
Once you've got this thing built, I doubt it will float away. Congratulations on getting the pictures right-side up! So the roller chains power the up/down motion of the table legs? And the linear actuators push the end of the table out?

Yes the 12v gear motor is geared 60:1 so with 200 pounds on the table it doesn't even slow down. I used the same motor on my drill press table and loved it. Put a PWM control on to regulate the speed.
When covering the top with 80 20 3"X.75" is it better to leave gapes between extrusions or but up tight? I was thinking that you could bolt thru gapes if need be or is that not an issue?
Thanks
