You say you have a lathe and mill, so I'm looking forward to seeing your progress on this. Please post some pics of what you're doing and consider setting up a website for your project if you haven't already.
And of course I wanted to wait until after the move to our new home, with the change of ISP - and now of course I'm up to my [nevermind] in unpacking, with Her Indoors keeping a beady eye on me lest I get side-tracked, as I do.
Now, just where did I put that soldering station…
Cool :cool:Quote:

Or I could cut a rack (or ten) with my mini-mill. Just as soon as I get the workbench built, the mill and lathe set up, the kitchen remodelled, the electronics workstation assembled, the satellite TV installed, the cats fed, the grass cut (again - have you guys had much rain this year? Here in Canada it is just as wet as my old place in Scotland, only warmer)…
Wot!? Get sidetracked onto flightsim stuff from unpacking!?!?! Unheard of!:roll:Quote:

So long as everyone's posting their work, here's what I was doing tonight - working on a mounting bracket for the CDI servo. One of the best things in Solid Edge is the ability to unfold sheetmetal assemblies, makes them very easy to cut and fit.
They are just gorgeous! :DQuote:

Boring the centres out of the ring gears was a very tedious operation. On the test set, it took 2 hours to bore a 20mm drilled hole out to 60mm through 9mm thickness. What a pain! Quick as a flash you say "Holesaw!". Sorry wrong answer. Holesaws just jam in the soft aluminium, and driving a 55mm holesaw takes a) A lot of torque and b) puts huge loads on the material and the equipment.
Some time ago I fabricated this rig for making mould masters for my throttle quad knobs. It did the trick very nicely and a) It doesn't flog the guts out of any of the machinery, b) it took about 5 minutes to charge through 9mm of metal and c) it doesn't turn the cutout metal to complete waste. The best part is, the disks that come out of the centre could be used later to make smaller gears.
Take a peek.
Nice work mate. Attached, all the gears we'll ever need for the CAD.
Yeehaw! Now that's a compound gear if I ever saw one.
