I was talking to a guy about setting my timing, he comes highly reccomended by a local diesel shop. So he asked what I was wanting, and what I had done. I told him I wanted the timing bump mainly for MPG, and I had a plate that I had ground down, he asked how I ground it and I described the profile, then he asked if I used a hand grinder, I said no, I used a Dremel and went real slow. He said he always freaks when someone says they did it themselves. He said he had one guy that used a torch and just cut his to the profile he wanted I just can't imaging taking a torch to my plate!

 

Some people out there are pretty bright. I couldn't imagine how that looked when finished.

 

yeah the whole torch thing on internal motor parts doesnt sound too smart.

 

No kidding..

some people just dont think... Dremel will work just fine.... Nick, what did you grind your plate to? 10 approx?

i'll bet that cat even left the plate in the pump when he done it, to make sure he didn't cut off to much so it would still stay in place. can we say uhhh hmmm how to put it?? edited make sure he puts a new chrome canuder valve on there with it lol

 

Real mellow version of a 100. Not as aggressive on the lo wend, and then just flat. I have it centerd in the pump.

 

From an old man that just started with these things, why even have a plate?

..Preston..

 

Without a plate the rack can extend too far and break off a pin that will cost you about $1200 to replace.
May take awhile but will eventually happen. Never fails that a person comes on boards such this touting removing the plate completely comes back later with their tail between their legs.

 

A Dremel is a hand-grinder, as compared to an NC automatic grinder.

A plasma-arc - which is an electric 'torch' - can achieve a very smooth, compared to a gas torch, profile, needing only minor polish\grinding.

Still, as the factory plates appear to be pressure-cast, rather than cut and machined, applying any high heat seems risky.

Pressure-cast produces the final product, needing no machining or polishing steps, with extrude-hone type deburring in some cases.

 

I've read of people using some sort of extremely high water pressure method of cutting plates. Don't remember the name of the process.

 

I've heard of it, also, Bill - it's hydro-something-or-other

 

I think that would be water-jet cutting, it's a pretty accurate cutting method. The guy that does it around says to within .001 .

 

Any one ever seen one of these in action, I have and let me tell you they're awsome. The guy running said the water was moving faster than Mach 1 at the tip. It uses a combination of water and some type of sand looking stuff.
