Mastermind Meets a Brand New MS460

[Smittysrepair]

hey randy my name is terry and i think we suffer from the same affliction. is there any hope for us?

I am willing to bet that if they come out with a drug to cure it, all of our wives will buy it and none of us will be willing to take it!

The cutter was cutting all the way out. The edge you are seeing is where the sandpaper didn't go all the way out when I did the clean up. It might be .002 - .003 high......much less than the squish area. So I can't see it being an issue.

yeah if thats all it is it should be of no consequence,,, Cool thread,,, thanks for posting,,, is that delrin round stock a type of nylon compound? is it expensive??

What is the D-shaped 046 cylinders that you guys speak of? Also, nice clean work mastermind.

 

[Mastermind]

What did you decide to do with the intake port?

It's all done. I just like polishing and beveling a bit more.

Timing numbers ended up (My notes are in the shop so I could be off a degree or two)

Exhaust: 101° ATDC
Transfers: 118° ATDC
Intake: 79° ATDC

Or......in duration speak.

Exhaust: 158°
Blowdown: 17°
Intake: 158°

Have you scaled them?

Delrin is a Dupont material. I get it from an ebay seller.......

I did check it's specs for machineability...etc. Good stuff.

Yep....

That should do it

 

[Bowtie]

Yes Sir......I have. :msp_thumbup:

I better quit looking at the model badges when I pick them up, LOL! (I have not scaled either, I dont even own a scale that measures that high)

I think I used delrin kingpins in my old twin I beam ford years ago?

 

[Mastermind]

Yep....

That should do it

I'm glad you approve. After all those are per your recommendation.

Yeah that plant where its made is about 12 miles SE from my house... let me do some checking tomorrow,,, I may be able to beat his price by getting larger blanks that are culls but will turn down fine for our use,,,, my buddys machine shop does alot of their hypercompressor components specialty work,,,, interesting,,,,, this is cool,,,, back in my early piston ported 100cc kart racing days we used a slightly modified piston crown w/the skirts cut off just below the wristpin boss,,, I beleive we had the cutter inbedded in the deck of the piston to cut the chambers the same way and did imention we used lots & lots of sandpaper,,, :msp_thumbup:

No a chance..... :msp_mellow:



Prove it. :hmm3grin2orange:

MEH!!! You disbeliever, you just don't want to go to the hassle of setting it up!! :hmm3grin2orange: I read it in many places, and makes sense to me. I'll continue to do it, but you do what you think is right for your saws. I'm not saying square is bad, just saying taper is better!

HaHaHaHaHa....... You get the idea. lol

I'm sure on a motorcycle or even a really hot race saw it would matter. These saw engines are a primitive beast for sure. :msp_unsure:

Besides.......it would cost me hard earned compression. :msp_ohmy:


I could cut the insert on a 2 degree angle when I grind the cutting angle...........

Hi there Randy
Myself and a few others would like to watch the 441CMTronic build please.:biggrinbounce2:

Believe me when I tell you that build will be well documented on AS.

Nice Randy. How did ya set up the cylinder to cut it?

I cut it by hand........ :msp_wink:

all i sent him was money
