Hi there, and good luck! I will check out the sites listed, thank you so much! Regards 'cost', A new machine will cost over £3000.00. So about £60.00 or so for what I want sounds pretty reasonable! Thanks again.

Hi, I appreciate your help, thank you. Yes I do want to make a machine that does a job. But the machine is pretty small. This link will take you to the machine type I am thinking of. It is one of the hand wound machines. http://www.sepha.com/en/products/ Thanks

Hello diluders, I am not specifically trying to built an all Lego machine. I have limited movement and find it hard to use tools. So I thought Lego as the basis of anything I make. There has to be two shafts which need to be a finished size of ~ 50 mm. I will have to build this thickness up from the max thickness the Lego holes will take. I believe the free movement size of the hole is 4.73 mm. If you can verify that I will know where to start. I was thinking of get the strongest type of BALSA as a test and I can get that in 5 mm sizes. It may be strong enough to use anyway, I do not know yet, but I will also need to find non Lego gears, as the Lego gears buckled when I tried a mock up of the machine. It may be me, but I am finding it hard to find or make a handle to use to drive the gears that drive the shafts. Any ideas on that would be obliged. I have checked out the other shafts mentioned and most are too short. They need to be at least 25 cm. Take care, habit Hi vassal, I was thinking of using the round axles and perhaps linking them to the short stub axles you mention. I was also thinking of drilling the 4 bricks I need to fit a slightly larger rod, one that comes as a known standard size? Many thanks for your input and help. habit Hi, after some fiddling I got this: http://www.peeron.com/inv/sets/802-1 It is not what I am after but that link you gave led to it. Habit I actually got my Lego from the Robotic shop mention. On second thoughts I cannot use the stubb axles, as I need the axle to go through the hole on the brick to attach the gears and handle to turn the whole thing. Thanks. habit

Hi, I appreciate your reply, many thanks. Have you tried to find metal axles for Lego before? I know you can get a couple of replacement Lego 'stub-axles in metal but they allow just one wheel to be used. I want a series of drives coming off the one shaft. Doing this with normal Lego and the axles screw up and twist. There has to be some out there some where! Help. I have seen some but cannot recall where, but they and the metal replacement parts are almost a $100 ! Cheers. I have not got back to this site until now so will take a look at the site mention by you diluders, thanks. But I do recall as I said Lego making a very short stub-axle. I am several hundred Dollars into Lego as it was all I could think about and knew of very few other sets which after I got the Lego, turned out to be more suitable! But I know I can build this machine if I can find metal Lego axles, or replaces round Lego axles to fix gears on then gave tiny screws to hold them onto the rod. The "X" shape of the Lego axle brings it down to about 2 or 3 mm, I am not worried about that as I need a round axle. Or more correctly, a shaft or series of shafts. Lego bricks are strong, and will take the drive I have in mind I just can't find any bar. And that means ANY bar right now and for the last year. But with help from you two guys I stand a better chance, thank you.

Hi, I am new and would like info on steel or other metal round and other shaped axles for Lego please? It may have been mentioned before but it is new to me, OK? Hope someone can help. Not been computing for long and have found what I need but cannot trace an address. But being experts well into Lego I thought you may know other items along the axle/drive chain theme which could help? I started to build what I want but it has not really got a name, eccept it is a little machine. It has to work like a machine would, all be it on a smaller scale. The drive will either be motors or, more like, a hand turned crank. I decided on Lego because it is so versitile, and to be honest I did not know of many other Model Building Sets. I have make a few mock ups to get some idea of size, but the hand turned crank, which is used to drive the top roller on a machine which is very similar to a really printing press. That roller then drives the bottom roller. The problem is the Lego axles, and I am not sure about the gears, are not up to the torque. I want to cut puzzle pieces and there is just not enough strength in the Lego standard axles, so I need metal or some ideas really? habit
