I have been working on this off and on for a few weekends now. Not making alot of progress but I am not in a huge hurry either. I purchased Nook precission 1/2-10 acme rod for the leadscrews. I plan to try to use my Xylotex 269 oz. kit to run it. I will probably also but DumpsterCNC AB nuts and might even give his couplers a try. I have also made a few small changes to some of the drawings/parts and I am thinking of a few more. I am including a picture of the modification to the long parts for the X axis torsion box. I also squared the holes in this part. I liked the idea of having them hold drawers so I squared them to make installing /making easier. While purchasing my material I called a local plastic supplier. They sold me what I wanted by the pound if I could get it from the cut-off bin. The plastic I purchased was approx $32.00 and I think I have more than enough. This might be a good way for some people to go who want to cut their own parts but not have to buy a sheet. Here are some pictures to start with.
Well it is starting to look familiar. I can look at the drawings and pictures from others all day long, but you acctually have to see one to realize how big this thing is. I have all of the wood parts cut for my Z axis and for my Y gantry lower torsion box. I did a modification to the torsion box. I added a 1/4 x 1/4 tongue to the end pieces and put a groove in the skin (top and bottom). I am hoping this allows a little more glue surface and a better bite on the end peices. I did this after seeing a video that suggested the machine may benefit from more strength in this area. I will also add the threaded rod throught the Gantry uprights. I have all of the inner parts of the X axis torsion box cut, will hopefully do the skins this weekend. Oh yeah...I added a few more parts to the "not so good" pile. At this rate I will be able to build a whole other router...might not cut straight..but it will be another router...LOL.
txcowdog - I made the pieces interlocking because I wanted more than just a butt joint. Once the MDF soaks up some glue and swells that joint should be TIGHT fitting. I also figure that when the cross piece is installed it will help to insure better alighnment between the faces. Of course because I could was also lurking in the back of my mind...LOL. Where are you in Houston? I am on Hwy6 about 6miles north of I-10.
Ordered my bolts from bolt depot tonight. Got tired of driving back and forth to HD when building the last one. It is only about 5 miles away but can take 20-30 minutes to get there. Anyway, if anyone orders from there watch the pricing. If you need to buy 40 or more then it is cheaper to buy boxes of 100. Shipping will be more due to weight but I am always looking for bolts and never have any. I figure the extra will not go to waste. Thought for just a minute about buying all chrome, add a little bling to my router. No parts cut tonight, did my taxes instead.
