For the original Huxley design i felt that the y-axis was over complicated, and required the use of a froglet (complex flat shape to hold the bearings etc) which was recommended to be laser cut. I chose the simpler option of using a square of aluminium sheet (160x160mm) and bonding 4 PTFE bushings to the underside (using long setting epoxy resin was worse than super glue; which is still holding firm!).
To hold the timing belt i was feeling lazy so i drilled a couple of holes in a bottle cap and bolted it to the underside of the aluminium sheet to clamp down on the belt. Simple but effective!
Finally i wanted to make the build platform quick release using magnets, so i can get on with a new build while i clean up the old platform. To achieve this i used a nut and bolt with a spring inbetween (to adjust the level of the bed) I glued a neodymium magnet onto the bolt head (M6 bolt & 10mm diameter magnet) and to the underside of the build platform (making sure they were the correct orientation!) This worked surprisingly well, i could use the head of the extruder to align the build platform buy turning the nuts.
Also working to researching composites has its benifits.. a carbon fibre build platform!
