looking good.

have fun making the torsion box bed and base supports. i started with those. i used my pneumatic brad nailer to hold things in place a bit while the glue dried cause it's hard to get a clamp on everything (at least I don't have the clamps to do it). but i did clamp all the edge pieces well. also, i cut myself some 7.5" and 8" scraps to use as gauge blocks that I could lay in there and easily layout the cross pieces for each row as I glued it up.

Well it rain again today still raining up in Atlanta hope it stay up there

I was working on the X axis plate I got that done and the gantry done I put on the pipes and just about all the roller bearing was rolling on the pips except for one it looke like its off by 1/8" I may have to redrill that one bearing then it will be right.

I'm also redoing the adjustment blocks some of my bolts was coming lose when I would ajust the pipies I'll use play wood on this again till I can get me
some thick delrin or aluminum.

I made some more adjustment blocks and they didn't work out the pressed plywood
was splitting on me not like the MDF though so I said screw it I'm ordering me some eith HPDE or Delrin what type of drill bit did you to drill through the HDPE or Delrin ?

[tbenefi33]

Ok I went on ahead and done it I order the HDPE from Mcmaster-car.com
I got the cut to length so I wouldn't have to cut much.
I got
1 pice 3/4" x 2" x2' = $3.67 FT 2' = $7.34
1 pice 3/4" x 2 1/2 x 2' = 4.23 FT 2' = $8.68
--------------------------------------------
total $ 16.02
shipping $5.00
-----------------------------------------
FInal with local tax $22.69

not bad at all least this stuff won't split on me :-) and it last a life time or more.

Hello I got the X and Y axis plate done today but somthing not adding up all the rollerbearing are rolling fine except for one I guess it will roll when I put on the adjustment block to adjust the pipes they line up pretty good a small pice on the z axis chiped on the corner where roller bearing goes Other then that and the one roller bearing not rolling it went together good. Oh yah my black cat Dale came to help me.. Well I'm take a break from this I'm heading up to North Carolina to charakee harris casino with my dad I'll be back Tuesday to finish up hopfully my Plastic will get here and I can make my new adjustment blocks.

Well guy I got some bad new my build has come to a complete halt last few days we been having a lot rain and I thought I had the basement wasleaky free but guess I was wrong some water got in there not much but it was enough to do some major damage to MDF which totaly sucks cause I was doing good now I know why my pices was splitting here a pice of MDF when moisture gets to it realy bad all the othere pices are getting to look like that. After see this I'll probley just end up buying me one but first I got to put some more drylock down on the basement floor this totaly sucks.

Hay the build log back on I've been out of town for the past few day I got my Plastic in for my small and large adjustment block in while I gone to Charokee North Carolina didn't win anything but had a good time. I went down and look at the rian damgae not hardly at all guess I lucky this time. All I got to do is find out why my bearing are not lining up on one side I"ll be good to go All I got to do is probley is set the adjustment block on there I'll be good to go hopefully.
I'm back I've had a full weeks rest I'm ready start building again I guess we all need a break every now and then.

Well after resting from a long ride in the truck I went down to the basement and dome some work on the small adjustment blocks they turned out pretty good HDPE not as bad I though it was going to be but you do need a table saw and drill press to work with. Don't work with it slow peck at it. It will gum up the drill bits (Thank You for the info on that on Ron Broken balsa). I need to make 7 more small adjustment block and 4 large adjustment block oh yah plastic taps out better they MDEF and will way longer then a life time.

[tbenefi33]

I went down to the basement and mades some Small HDPE adjustment block andI put four of them on there and one of my Roller Bearing is not touching the pipe bummer I may have raise that one bearing juat a little and I will be set on that part her a pic of see what yall think about it ?
I have a video of it any body wish to take a look at it just Privatemessage me I'll sent it to you It's 5 mb wmv to large for this site.

[tbenefi33]

Well guys I'm sorry to say this is the end of my build for sure cause I working down there and had a few more pices split on me. I guess all the
rain we been having the mosthure just screwed up the MDF more then I
though. There comes a time that you got to say screw it and start on someting elese least I tried. Here a pic of what how bad it split I wasn't hardly doing anyhing to it but putting on the adjustment block and that whole back side came out. Hay if yall had a beting pool going on to see if
I would finish or not let me know who won.....LOL Got have a little fun.
Yall have a good one and safe one.

Sorry to hear that.

As much as I can I am using the bolt and nut method rather than having the "wood" support the pressure of the threads. I purchased a punch of threaded metal dowel nuts for edges and normal nuts for the flat areas (like the bearing blocks)....I don't trust MDF or HDPE to hold....

If you decide to continue you may want to try and support the MDF on both sides with clamps while you are tightening the bolts.

I'll probley either buy me cnc or rebuild with a differnt type material then MDF I'm open for suggetion on other type of material or a good cnc router or mill ?

[mlabruyere]

What are you going to do with everything you've already built? I hope you aren't going to just trash it.....

[tbenefi33]

I'll the pice of MDF that got real bad from the moisture some turned black on me I trased them and the othere one that didn't get any moisture on it cuase I had um up off the floor I saving them and the other stuff like roller bearing, delrin and etc. That stuff cost to much to trash I can use it on another project.

[bobwparker]

Does anyone have any idea how precise the base support and bed supports need to be? Upon gluing, it was necessary to flex the top piece to get it to stick to one edge of the ladder structure (probably no more than 1/4") - how much of a problem is this? Should I start it over?
