OK, got it all to work with 1/4 material. With the new material cost, and the slower feedrate (which wears on the plasma tips) and the drilling now (holes taper and cant do a direct tap, but can use the hole as a drill guide) and tapping the holes Im at 26.00 per plate.
The kicker, the coils...
I can, I have an offshoot of autocad from TorchMate, and the easiest thing I know to do is create a tool path around the outer edge, then noid edit the lead in and move the area around the plug back to where it was. So yes, I can maintain coil centerline.
Gotcha, Ill grab a coil and some thicker material tomorrow and work the opening. Its so close that about 10 seconds with a diegrinder would fix it on each hole, but Ill mod the drawing just a little so that wont have to happen.
That bracket is only 1/8th. I can do thicker, I tght I had just mentioned that when I offered. How are these getting held down? Nut welded to the hex cap below?
I know I can do 3/16th with no issues and will just have to slow the cut speed down for 1/4 inch. Alum takes a lot of power...
Ill cut a bunch once the coil fits. I see from the first pics on page one that the coil mounts from underneath. Ill actually "borrow" the coil from the parts store and get them to fit from underneath.
Got some pics. Are these coils meant to mount on top of the bracket or below? They fit great on top with the hold down bolt lining up great, but its just a little to small to tilt the coil in from the bottom side.
I want to test fit the coil tomorrow, then I can cut another one and get them to you Monday. Then maybe you can fit in car and then I can cut the rest?
Whats your plan to get vacuum in there? Any shots of it mounted? Does it unscrew for draining or is there a drain valve? I remember on an old engine I would get about a paint cap full of water/oil residue once a week when I drained it while washing the car. I imagine the area you live in...
Heres the new plenums I form for t/b that are square to the bases. But others will get a flat plate and a D shape depending on the radius.
Just to give you some ideas.
Its also nice to get some stacks on the inside to pick up the air off the plenum wall.
I dont have pics anymore, but I made a plenum that welded to the stock runners, cleared the alternator in the stock location. I rotated the T/B 90* so the linkage was on top and remounted the rod/linkage to the top of the plenum. It retained cruise, and the stock IAC (I would leave that, even...
I need to move one hole, just going to weld it up and relocate. I need to make a wee bit more room for the plugs to come off without taking the cover off and deburr it. I looks like it will work just fine, its hard to tell with just 4 coils and no mount studs. Ill grab a few bolts tomorrow...
I got this far, then realized how the coil was actually captured on top and I moved the hole to much. Ill setup later and make the hole larger and maybe even grind my head to exact hole placement then cut another for ya.
