I´ve welded spiders, but never in anything smaller than a D-60. Seen some guys, destroy 9 inch fords with a mini spool. I don´t really think the 35 or the 30 is up to it. The D35 isn´t that robust to begin with, and locking it up and possibly, in certain situations, having all the torque from the motor, on one axle, with no way to dump it (slip the loose tire) will probably break something, someday and possibly destroy some associated drivetrain parts in the process.
If you think about it for a minute, if the tires don´t slip, the gears in the diff don´t break, the U-joints don´t break, the transmission gears don´t shatter, the tranfer chain or gears break, the clutch doesn´t explode, the crank will probably break. I´d rather have a tire slip or a limited slip diff. to get rid of the extra torque, when I pop the clutch and the tire doesn´t turn.
I´ve snapped a few U-joints and tranfer chains, with an open differential and a big rock and a gas pedal, D44 and engine torque. Once sheared off the flywheel bolts. They mostly use mini spools for light wieght flat track racers and full spools for drag, sand or mud racing. Spools or locked diff´s don´t work well when driving around corners.[addsig]
