started 2 5x10 tables. got most of the machining done on all the alum parts.
Have a few photos of the progress. Using candc electronics. More details later

Looking good..............jb

Nice build! Are you using steel for the gantry too?

[dnelso]

Yes the gantry will be steel. We will be using the tables for plasma and router table. Here is the link to the first table i built, http://www.cnczone.com/forums/plasma...d_4x10.html.It will be very similar to this table

[AndiKid]

I just LOVE LOVE LOOOOOOOVE your builds dnelso, the engineering, the planning and the great looks.. just truly inspiring!!

[dnelso]

Thanks Andikidd, Did you finish your table?
Dave

[dnelso]

got a few more things done

[Boogiemanz1]

Dave that is a very clean and neat build. The nicest I've seen so far.....jb

[Dustin407]

Dnelso,

Your build looks very nice... I followed your entire first build with interest. Ive noticed you made a few minor changes but overall kept the same exact design as #1. I like your lcd monitor stand, I bet alot of people miss that in the photos. Good Luck... :cheers:

[dnelso]

thanks dustin and Boogiemanz. I only changed a few things on theses tables. The table is 5x10 the old table was 4x10. The gantry is also 3 inches higher.I want to use a 4th axis for notching tubing on these tables. I still have to machine a few more pieces and am waiting on the water trays. Here are a few pics of the progress.

[Boogiemanz1]

Dave, I have been getting to do a little on my machine. I don't have the benefit of a floor plate like yours and squaring and and leveling is a lot tougher. I used 4x8 tubing because I had it, and put an 1/8 bottom in it for a water bed. I used an 80/20 brand slotted extrusion in a 1"x3" configuration to keep my linear rails and 1/2" gear rack parallel, and am in the process of getting them fastened to the sides of the table.
I noticed you have added more adjustment on these tables. I'll probably be doing that in a couple of weeks. I appreciate your sharing.. you are sure helping me..............john

Here are a few more pics.Got the gear boxes finished.Put the bearing races in with the hot plate.Had to drill lots of holes in the gear rack. Should have some movement this week i hope

Hi guys first time poster long time lurker, just doing my homework - hopefully starting a build soon.

Dave, can you please tell me more about your linear guides and rails, sizes on X and Y, Hiwin HG I presume, load type, preload code. I also noticed you used flange type guides on this build? Do you think there would be any advantage of using twin rails on the x axis for routing. Great build Dave, looks very professional.

[dnelso]

Here are the rails that we used. The first table i built used 25mm rails. These rails are 30mm and were cheaper.I like the flange mounts. I have used the router to cut wood and some alum. For what i cut i don't see a need for 2 rails on the x axis.

[blarb]

Any more progres Dave ?

What do you think of these rails with racks attached.

[dnelso]

Blarb
No major progress. Got all the racks mounted on both tables. I like the rails with the rack on them i just wonder what the cost is. They are hardened so the gear would wear and the rack wouldn't that's good.
Dave

[blarb]

I dont think ill be getting those $660.00 per metre $99.00 per block. I would like to come up with a way to make the racks adjustable or do you think it would not be necessary ? Does your pinion keep the same backlash the full length of the table.

[dnelso]

I had a feeling they would be expensive. When i mount the rack i used a machined spacer off the rails so the spacing is the same the length of the rail.If the spacing is correct you will not have any backlash issues. I tried a spring mounted gear reduction box on a different project and had to run a lot of spring tension to get the backlash out. The pinion gears showed a lot of wear in a short period of time. With this system i don't have those problems.
