I could then use two stepper motors driven by a microprocessor. The micro could generate a random number between one and six and rtotate the dicebto show the correct side.

Or there is the holding-the-nut-in-place-with-a-box spanner trick. Or employment of Selotape or Bluetack or surgical forceps. But obviously none of those will work here.<br /><br />For those lacking Ralph's patience (27 attempts to get the nut on the bolt would be pushing the limits of mine a bit too far, I think) it struck me a less trying way of solving this Meccano "locked box" mystery (shades of Sherlock Holmes?) would be to use that ever faithful old friend Araldite.<br /><br />A couple of minute dabs of Araldite of opposite edges of each of the nuts to be secured inside the "locked box" by bolts inserted from the outside will do the trick.<br /><br />1) Position the prepared nuts exactly in place over the selected holes of the unassembled flanged plates<br />2) tighten the nuts in place with the bolts so that the nuts will adhere to the flanged plates under pressure<br />3| set aside for a few hours to let the Araldite dry<br />4) unscrew and remove the bolts<br />5) assemble the flanged plates<br />6) reinsert the bolts and screw firmly into the pre-Araldite-positioned nuts.<br /><br />Araldite is powerful stuff, so use only the tiniest pinpricks of it on the edges of the nuts in order to avoid any of it getting into the screwholes of the nuts.<br /><br />Michelle O'BrienAnonymoushttps://www.blogger.com/profile/05547978598367808990noreply@blogger.comtag:blogger.com,1999:blog-2344605508503053589.post-1793441879720534132013-11-26T01:54:41.772+00:002013-11-26T01:54:41.772+00:00It is interesting how a small difference in the de...It is interesting how a small difference in the design of the part can make so much difference. I don't think Meccano have ever used these, and the other small flanged plates, to their full potential as the don't have the threaded boss (Part No.64) available any longer. Using it makes it very easy to build totally enclosed forms.Ralph Laughtonhttps://www.blogger.com/profile/05400542638638661314noreply@blogger.comtag:blogger.com,1999:blog-2344605508503053589.post-84502190645436854292013-11-26T01:36:44.592+00:002013-11-26T01:36:44.592+00:00I didn't have enough genuine flanged plates wh...I didn't have enough genuine flanged plates when I built my original, hence the slightly different replicas.<br /><br />- Pauli<br />paulihttps://www.blogger.com/profile/02615198929780787084noreply@blogger.com
