Delipping bowls, pistons still in motor?

[isootmypants]

Was wondering, put the one I'm working on, at TDC. Make a plate that bolts to block where head bolts go, and make some sort of gradual size to widen it. Use a dremel. Obviously cover each hole and clean it out. Then move to next one. I was wondering if anyone has done it.

Confederate?

 

[Arisley]

I would never, ever do that.

Think of all the little metal pieces... No way in hell you'd keep every single fragment out of where it shouldn't be.

So shiny and new.......

Haha hey it was a thought. And Jason, pm me price on those and girdle

I thought about it once with a junkyard engine i slapped in one year just to finish the season. Only reason i didn was i was afraid of blowing new head gaskets. Knew i was safe with the 160k mile ones. But that was a temp engine in a puller lol.

On the pistons..you want them de-lipped only or

Coated (top or top and skirt)
Valve reliefs

a router would be better then a dremel for the homebrew delip

You ever try using a router on metal? And if so, what kind of bit did you use?

 

[Bustedknuckles]

I know its been done in the duramax world and I'm sure plenty of gasser guys have done it.

Is there any benefits to de-lipping other than to prevent cracking

I think dzchevy (Dustin i think is his name) did some on a 6.4 with a router, but the engine was disassembled.

aluminum routers easily. but there are a lot of different aluminums so I dunno how a piston would take it.

I guess you didn't read the comments after the video. Just because you can doesn't mean its safe to do. There isn't a router manufacturer or bit maker out there that would recommend using a router on any metal. The bit can shatter causing severe bodily injury.

Routers usually run at 15,000 to 20,000 rpm. Metal die grinders run at about 3,000 rpm using speed rated stones or carbide bits. Lathes run maybe 150-300rpm. So when the wood rated bit shatters, you're in trouble.

Just because you see some idiot do it on the internet doesn't mean its safe or results in a quality job.

Even the idiots in the video said "Be careful", they knew it was dangerous. And it seemed like they used a speed reducing supply to slow the router down.

Die grinders run 20,000 without load
