Here is a link to the prototype gridbeam wooden Eiffel The plan is to play with the form of the structure until I'm happy, then rebuild it using the same technique as my daughter gridbeam chairby currystomper - Developers
Folks After a bit of moving round I did get my basic cube made and I've learnt a bit. I've double spaced my holes to save drilling, but if you do that you have to alternative down each side otherwise you'll not be able to make trijoints. I've make my hole wrong so don't copy my beam - I make one up right at some point and post a pic. Was surprised how well it when together considering how slopby currystomper - Developers
I was wondering if a stack of blank copper clad boards ( FR4 ) could be used as a insulator /heat sink, simple to machine and made to tight tolerances CSby currystomper - Mechanics
Lets take this to the next step - wouldn't it be cool if the rep rap could work with self replicating materials... ;-) CSby currystomper - Developers
Scatty idea.. What about a printer on tracks on a big plate of glass - move the printer not the parts - may be the printer would go down on supports while printing then lift on tracks to move to a new spot... ...I told you it was scatty!! CSby currystomper - Developers
I've tried to build up a a basic cube and as I thought the acuracy of the holes that I've made with my home made pillar drill are not accurate enough, three out of the four top joints worked OK but I've not been able to get the fourth joint to work. As I've said its back to plan B - where I only predrill some of the holes and use wood screws to join to the blind wood. ...more later. CSby currystomper - Developers
Just got the bolts - surprisingly at least one joint works!! Tomorrow I will start building it up a bit more...... CSby currystomper - Developers
Yup that the stuff -- can be made out of wood or metal beams - the idea behind Eiffel is that the machine is capable of making its own beam's - but I'm making a 'strap so I've got to make the first generation of beam's CSby currystomper - Developers
Hi Folks I've working away this week on building some wooden Gridbeam parts - I now have 8 grid beams, However I suspect that the drilling will not be accurate enough to build a good frame with (I'm waiting for some bolts to come via EBay to check this out). It seems that I have spent a lot of time building a pillar drill and drilling out the gridbeam without get a good system. Its a bit frustraby currystomper - Developers
