22/9/00 Decisions... | |
Term has started back at college so I'm snowed under inducting students, however I have had time to sort out the pneumatics order. I've sent off for an SMC LDT100-125 piston with a couple of SMC VS 3135 3 port valves and some AQ3000quick exhausts, all from Graham Leacock, who is an unreasonably helpful chap. Following Killerhurtz recommendations on the RW forum I phoned up a local fire extinguisher company "Pyrotec" who service our college, and asked if they had any spare extinguishers I could use for the high pressure side. They very generously gave me 2. Then I found out the regulations require the extinguishers to be under 5 years old, so I e-mailed them and they are giving me another 2, all I can say is Thanks. I'm still chewing over motors, but it looks like I'll be using Roger Plants Litton motors and cut down axles as it seems the least expensive route. I'd hoped to get some Bosch GPA's but Wheely big cheese did ok with the Littons, and they are considerably cheaper. |
All of the robots I have built have failed in fights, and usually at the axles/wheels, it's like a running joke. So why should it be any different with this featherweight? Meathammer was designed back in 2005/06 when using 4 drill motors was a bit of a novelty... it was made more novel still by mounting the epicyclic gear cages directly to the chassis, which unfortunately sends all the drive shocks back through the gearbox. The original version ran for a number of fights at modelworld 2006? and even won some, especially the sumo, which favoured its very low profile. I've just rebuilt the gearboxes with all metal gears, and tested it, and it seems it should last for at least one fight… but as I put it in the car after testing, I noted one of the wheels had nearly fallen off. Mark that bolt for Lockthreading! All this got me thinking if I could make something less likely to lose a wheel, break a gearbox etc I have a huge pile of bits and bobs that were destined for heavie...
