This is fantastic, all this info in one place/thread. Makes me wanna go out in the garage and tear a saw apart.

Thanks for taking the time and effort to post this , Randy . These type threads are always interesting and I 'd be hard pressed to think of one where I didn't pick up something valuable .

 

[Mastermind]

Thanks John. This is a recycled thread......but has a lot of pics and video. I figured these guys might enjoy it.

 

[Frank bierce]

Fantastic amount of information!! Well done videos, and photos.

Ok Mr Randy as I said I have not even touched one of these so tell me I'm an idiot if I ask the wrong question.
I pretty sure it was you that told me the trans are kinda like the 661. And they open on the exhaust side first. I'm curious on this. If you don't mind throwing in your knowledge on this. I'm all ears and curious.

 

[Mastermind]

What are you asking?

 

[Miller Mod Saws]

What are you asking?

Is there a pupose for this other than its the main flow port being the trans feed up the front?

[Mastermind]

They sorta open on the ends first.

I'm not sure why......but I think it has to do with the exhaust scavenging BS they talk about.

Let the chips fall where they lay!

Thank you! I was intrigued by this is the 661 builds but ended up just doing a straight across trans in one and the other I set the exhaust side flat but 2° higher than intake. But it's hard to do my water testing on this cylinder as most of it just comes out the exhaust side trans. Sorry for my ramblings. Just trying to learn and understand.

Beautiful thread, one of the best I've seen!

Agreed. I love the build threads

Man that's cool!

 

[Frank bierce]

After seeing a few of these builds, it would be nice to have a "builds" section to reference. That way they don't get lost in the archives..I'm sure they will come up with a search, but a section to show off builds, from mild...to wild, would be nice.

 

[Magic_Man]

I also like how he quickly posted all of the build info before many were able to comment. Keeps all the technical build info together at the front and then the conversation can follow after. Makes it nice and clean for those that don't want to read all of a 30 page build to piece the info together.

SO nice and clean. Need another T1 build! Great sharing of your work and tips. I noticed the top cover screws were slotted and torx. Is that a 461 thing?
