Nice work I have the same equipment (Sioux) in my shop. I needed the brush up. I have the knurl tool and reamer. Nothing wrong with it also the rifle groove aids in lubrication.
Wonder what I'm doing wrong. I have a sioux and the same pink stones. As soon as the stone touches the seat it gets a groove in it. On a Ford flathead. I believe it has factory hardened seats. Maybe that's the problem?
Been awhile since I did this stuff but I think I used to use gray stones for roughing them in, then go back and finish with the ruby stones. The Goodson catalog should explain the different types of stones.
@@ClaremontClassicGarage Hardened seats are rough on stones in general, if the seats are badly pitted you may need an actual seat cutter. Rides on the same pilot but has cutting edges on it like a reamer. If your block has seat inserts you have plenty of hardened material but if not, be aware that it will likely only be induction hardened. On those you only have .020 or so of a hardened surface and you may end up cutting through it before the seat is cleaned up. So just go slow and careful
Loved this vid. Brought back memories of high school shop,, doing my '69 429 heads. There is a Sioux machine here for sale with the attachments for $225...is that a decent price? Love your vid man! Thanks!
I'm curious about the linkage setup you have on you 200 ford. I have an 80 capri built motor with an offi triple intake but the linkage is shot. any info would be much appreciated
I built the one for my tri-power. It's just 1/4" rod with heim joints threaded on. The end carbs are linked together 1 to 1. The center carb has a slip joint connecting it to one of the outer carbs. For the first 1/3 of throttle travel the rod freely slides into a bigger piece of aluminum rod, at that point it bottoms out and starts pushing on the other end that's connected to the outer carb. On the outer carb, the linkage from the center carb is attached closer to the center of the throttle shaft than the linkage attaching it to the other outer carb. That way the outer carbs open faster than the center one, so it's progressive but you still get full throttle on all 3 carbs at once.
