Hi all,

I figured it was about time I started a thread on my build. This build will be a slow process since I'm laying out templates and using those to route the parts. So far I've managed to get all of the torsion box pieces cut, and assembled the Y axis and gantry bottom. The X axis is cut but yet to be assembled. I also have the left side of the gantry cut and glued together. The right side still needs to be glued and have the routing for the bearing block. I got carried away when I was cutting the gantry pieces and made the hole for the pipe in all 4 lol. Guess I'll find out if filling a 1" hole is as easy in wood as it is in steel :)

Unfortunately I haven't taken any pictures(been super busy making templates and cutting parts :)). I'll dig the camera out and take some shots to post later.

Didn't have much time today, but I took a couple shots to post. The first is the gantry bottom torsion box, and the second is the Y axis torsion box. I'll take more pics and post them later.

Looks good, just be careful with the skins as it looks (could be wrong) like one skin is cracked out a little bit. On the X table they need to be really impeccable otherwise you will have a tough time getting the same zero on it in one place to the next. Looking forward to the rest of your build log!

Yeah it did. Looks like there's something that got under the skin . I realized it too late though, but since nothing will be sitting on the skin I didn't stress over it much. I understand about the X-axis needing to be flat, but wouldn't skimming the spoil board clear any inconsistencies?

One thing i have thought about is having another floating table top of 1/2" material, sitting on top of 1/2" hdpe. or the 1/2" just being the spoil board.

glue the HDPE down to X-axis torsion box then use the machine to skim the tops of them, this will give you a flat and even 0 across it, then attach 1/2 mdf ontop of those via capret tape or nylon screws.

This will eliminate any improfections in youe X-Axis Torsion box.

Sounds interesting joe. I actually was at home depot and saw carpet tape randomly and remembered to try it out. Man is that stuff strong! Not a good hold down as it won't hold it true but it is a great alternative to adding tabs :).

Now that you mentioned the hdpe,I was wondering about the cutting board that people have used. Can someone give me an idea what I should look for? Or perhaps that spare corian cutting board we never use may come in handy :D

I believe most plastic cutting boards will be made of a HDPE like material. I puchased one from home goods and need more but I think that walmart, target, any cheap retail store like that will carry them for about $10 tops. Not sure where guys were finding 3/4" cutting boards, most come in 3/8" and 1/2" that I have seen. Also some people were calling local plastics companies looking for drop or scrap that they can buy by the pound.
