How are you going to deck the block?

 

I'm an amateur machinist, not capable of boring a block as that requires special equipment that I don't have, but as far as decking the block, my mill can handle it

 

How much will your machine shop charge to resurface the block? Only reason I ask is because I tried to use the CNC end mill at work to resurface a 3cyl jet ski engine and the results were less then desirable.

*edit* It might be possible with a large cutting head, but I would think the cost of the tooling would out weigh the savings of doing it yourself.

 

Hmm, I assume the end mill was much smaller than the deck, requiring multiple passes? I get the best surfacing finish when I do it in 1 pass with a single point fly cutter, consistent cut marks, and no trail left behind from switching positions

I'd rather not pay them to do to things I can do myself, I'm on a bit of a budget with this build

I realize I'm splitting hairs with this, the main reason I'm asking is I already told the machinist to wait for the plate to arrive, but doing so will give me another week or so of downtime, I'm considering telling him to go ahead and bore it

 

Well if your deck is true it shouldn't affect it if you bore it first. If the deck is not true, when you bolt the torque plate it it could skew the bore.

 

That's what I was thinking. The deck appears to have warped upward slightly on both ends, the gasket gouges are deeper on the ends, and if I run a dial indicator on it, you can see that the ends are higher by a few thou

this is the second 2jz block I've seen do this, it's possible they all do

It could be due to the perimeter bolt design. How large is your end mill?

 

my largest endmill is only about 1.25 inch, then I have some shell mills of larger diamters, but they dont cut well... when I deck a large surface like a block or a head, I set my fly cutter to cut about an inch or so bigger than the block surface

 

I was referring to the actual size of the end mill, not the tooling.

 

you mean the machine itself? its a Cincinnati Toolmaster, it uses an nt-40 taper

 

Have you done any inline 6 blocks on it? Just curious if the table has enough travel to make a full pass.

 

I measured the travel on the table to see if it would work, it makes it, but just barely
