Rubberman Posted April 9, 2009 Report Share Posted April 9, 2009 Suggestions on the best way to bore out a L16 intake. Started using the old drimmel tool, but nothings cutting it very well. Using the small 60 grit round sanding bits, eating them up quick. Used the stone type bits, eating them up also. I'm making progress, but anything quicker? This is slower than shit and shits pretty slow. Thanks Quote Link to comment
Phlebmaster Posted April 9, 2009 Report Share Posted April 9, 2009 Unless you have a milling tool and a drill press then you are stuck with a very time consuming job using up many sanding cylinders. 60 grit is good...just takes time. I did mine and I tried to speed it up too, but the sanding cylinders worked the best. Quote Link to comment
Rubberman Posted April 9, 2009 Author Report Share Posted April 9, 2009 Dang it, Phleb, I was affraid of that. I'm gonna head down to the parts store and by walfarts and see if I can find something I can put in my drill. I can put the intake in the vice to hold her but I don't want something that might bind the drill up and twist my hand off. Quote Link to comment
Phlebmaster Posted April 9, 2009 Report Share Posted April 9, 2009 This is what I used...much faster than the dremmel. Prepare for some wrist and hand fatigue. :lol: Quote Link to comment
Rubberman Posted April 9, 2009 Author Report Share Posted April 9, 2009 Heading to the store now. Thanks Phleb. Quote Link to comment

They were designed to cut and shape armor plate around the locks of file safes used to store classified materials. If there is a locksmith in your town, see if they could sell you a few of these bits. Quote Link to comment
Rubberman Posted April 10, 2009 Author Report Share Posted April 10, 2009 Mike, I bought some stone bits tonight. They're green and red, they don't cut worth a crap. There is a white ball bit, but I haven't tried it yet, thought the others were harder and would cut better, so I'll have to give it a try. I did get some round sanding bits with the layered sandpaper for my airtool, thats working the best so far. Still slow. Quote Link to comment
FoxyRoadster Posted April 10, 2009 Report Share Posted April 10, 2009 (edited) I use the grinding and cutting bits.. then polish with the sanding bits. What grind/cutting tip have you tried? http://www.drillspot.com/products/82066/Dremel_9901_Rotary_Carbide_Cutter little costly on their own, but I got like a crapload in my dremel kit.

Rubberman Posted April 10, 2009 Author Report Share Posted April 10, 2009 Foxy, I bought two of those at lowes earlier and it just ate them up. They were the carbide types. Quote Link to comment
FoxyRoadster Posted April 10, 2009 Report Share Posted April 10, 2009 Wow really? What was the number for it? I'll be home soon I'll get the numbers for all the bits I use to port and polish. I got like this 200 peice set last xmas Quote Link to comment

datzenmike Posted April 10, 2009 Report Share Posted April 10, 2009 Use a carbide bur to rough it out then sanding cylinders...... or an L20B intake. :D Quote Link to comment

The problem with those stone bits is that aluminum gets stuck in them...too soft. It is like trying to grind cheddar cheeze. :D Doesn't turn out well. Use the sanding cylinders I posted the picture of. That was the best way when I did mine. Quote Link to comment
mike Posted April 10, 2009 Report Share Posted April 10, 2009 I used a carbide cutter with an acorn shape in a 3/8" drill and built a little "jig" on my workbench to hold the intake steady. I got a fine cut one and it is slow going... about an hour a hole. Id get a medium cut one if I were to do it again. I bought a crappy cheap drill from a pawnshop for a few bucks(one I didnt care if I burned up) you can usually buy the dies there too, just make sure they are in good shape. If you go the drill route make sure you get one with a lock for the trigger other wise your hands will be hurting... If youve got an air compressor get a diegrinder and use that instead of a dremel. Its a tool youll use again and is worth buying. Also when sanding aluminum wear a mask, the dust/particles can screw you up pretty good. Quote Link to comment
DatDoug Posted April 10, 2009 Report Share Posted April 10, 2009 I found the best way to port a L16 mani is to give it to Ben (DatsunFish):D He does a good job in a reasonable amount of time but he thinks hes funny and paints it PINK:fu: Quote Link to comment
Rubberman Posted April 10, 2009 Author Report Share Posted April 10, 2009 The best thing that has worked is the sanding bits like Phlebs photos, but I got some that go in my airtool. Alot faster than a drill. I've put a total of about 2 hours into it off and on and I'm about done. Thanks for the help fellas. Quote Link to comment
datsunfish Posted April 11, 2009 Report Share Posted April 11, 2009 Alright. I think I am going to make a video on this subject. The best way is to chuck a straight router bit in a straight air grinder. Mark your opening dimensions and work it out to that point about 1/4" deep. Do each one and go in another 1/4" evening the wall surface. So yeah,router bit. Use sanding drums to clean up the surfaces but not to do the actual cutting. Stay tuned for the video since I think I will start on that today. Quote Link to comment
Rubberman Posted April 11, 2009 Author Report Share Posted April 11, 2009 Here's what the intake looks like after boring out and what I used. Quote Link to comment
420n620 Posted April 11, 2009 Report Share Posted April 11, 2009 nicly done, how long did it take to bore the intake. also how far inward did you bore it. Quote Link to comment
Rubberman Posted April 11, 2009 Author Report Share Posted April 11, 2009 nicly done, how long did it take to bore the intake. also how far inward did you bore it. 420, it took me about 4 to 5 hours off and on. I bored it in as far as I could get the sanding tool, about a inch and half in. It really wasn't that bad after I figured the best thing to use, plus I didn't do it all at once. Quote Link to comment
datsunfish Posted April 11, 2009 Report Share Posted April 11, 2009 Looks nice dude!:D The straight air grinder is a must. Good call! Quote Link to comment
