  1. the red is ATF floating uselessly on a layer of water I guess
  2. meanwhile in the cylinder bores
  3. man I think I've got real problems now, the bottom end is locked solid, I think I've disturbed the throttle body at some point and it's dumped the contents of the coolant jacket into the inlet manifold/cylinders. borescope tomorrow, FML
  4. it's pickled in brine, is this likely to cause issues?
  5. the throttle is now completely jammed shut and won't budge, god this car is such a fucking diva
  6. ok I've removed the residual pressure valve for the rear circuit but unfortunately that hasn't changed anything. Im thinking there might be a mechanical drag as well though as even with the lines cracked it's not exactly free spinning. I've just re-kitted the calipers and the pins are nice and greased, really don't want to get back in there I'll replace the rear lines and give it a flush too because why not
  7. I haven't really done much of anything in terms of flushing it out, I just figured that if there was a blockage further downstream, then cracking the line at the master wouldn't have released the pressure? The front half of the reservoir tees off to the front brakes and they're fine. The rear section has a single line, must tee off somewhere under the guts
  8. I've been struggling with the rear brakes on the starion locking on for some time now, its definitely w hydraulic issue, and as the brakes ease off if I crack ANY connection in the system, I think it's an issue with the master cylinder? I disconnected the pushrod from the brake pedal and made sure the piston was being allowed to return fully, so that's all good. The master has residual pressure valves in it which is apparently strange for a disc rear, can I remove them? I cleaned out the return port in the master cyl reservoir and it seemed to work fine on the bench but the moment I reinstalled it, it started giving shit again. Not sure if the port is blocked again, it looks as big from the top as the feed port but I could only get a .010" bit of wire through it in the end, not sure if it tapers or it's just loaded with crud. what would happen if I opened it out?
  9. we need to know how big your missus is first. a pic will do
  10. fuck that explains it lol I weld like I make love; with little ability but maximum enthusiasm
  11. Question for welders: Yesterday I successfully TIG welded a bunch of steel together. Then the argon bottle ran out. I got the new bottle (C02 this time) and had to change regulators to a cheap Chinese one as it was the only one that would fit. Today my welds (again on steel) are like they're not getting gas, instead of a weld puddle I'm getting sizzling and sparking and porous holes and shit. I can hear gas coming out of the nozzle when I pull the trigger though, so what the hell is the problem? Is C02 wrong for Tig? Has some asshole filled my c02 bottle with oxygen?
  12. That'd definitely do it, too... Price is getting a little up there for something thatd only be getting hauled out once or twice a year. Ideally I'd like to modify our 28v ground power unit as discussed above, but $500 doesn't even buy much sparky time these days. Anyway at least I've got a few options now
  13. @ajg193 it's for rigging some electric landing gear that has a dynamic brake on the actuator, the manual is insistent that in order to get everything to stop in the right place with the right tension on the locks given the momentum of the whole assembly, that it be rigged at 14v instead of 12v. It's not really "precisely 14v", just more something in line with what the bus would be expecting with the engine operating
  14. I have looked inside once and there's a TIE fighter in there, is that enough to go off
  15. Actually here's a tangental question - what we do have already is a 3 phase fed 28v DC ground power unit for starting turbines, how do I tap off a 14v feed from that without frying myself? it's the size of a doghouse and good for 200a
  16. people have shit to say when they see that sort of ingenuity hanging off their aircraft
  17. Another option would be running thirteen 14v 3a laptop chargers in parallel but I'd have to package it real nice
  18. That must be a beast of a charger... Ours is a big (and old) benchtop one but I think it tops out at 10a ... are you sure it's not an arc welder lol
  19. I'll bolt an alternator to an angle grinder and post results
  20. 18v is probably a bit much... Surely pulling 40 amps from that would melt it into a puddle?
  21. what's the best way of getting a 14v battery for cheap? I need 14v able to provide at least 40 amps for a minute or two. Basically I need a regular battery with an extra cell? We've just jumped off a running engine in the past but it's a bit of a pain in the ass
  22. I used an oil pressure cutout and bridged the relay on demand with a "prime" button that sortof doubles as a security system because it's a repurposed aircon button
