Finger Ports???????

[Mastermind]

I don't have any problem at all with that jug winning. The rules weren't broken.

The idea is that we are doing a work saw build off though........so I think the rules might be a little more thought out next year.

John seemed to be a super nice guy, and he did a great job running the saw.

Fun was had by all that were there, and that's what really mattered.

I think so Brad.

And that would be the way to go. OR.......would it distort the jug and make replating needed?

Put a wet rag in the cylinder sleeve when welding the outside of the jug ,with a wire feed spool gun you could weld a little at a time ,and the wire makes a great filler ,i think there is a clay that can be used to control heat also .

There's other ways to mount them besides welding and epoxy. There's aluminum brazing rod available.

The spool fun is probably the easiest process to use though.

In my opinion adding your definition of a work saw as a rule is bias. From what I've learned around here is that a work saw is defined as a saw, hopped up or not, that will still be running strong when the job is done. If a crazy hogged out mod holds to the test of time then why should it be ruled out as a work saw?

Mike you see them 2 loops of chain being sent to you for the Chain Build Off.

I'm not the one that makes the rules.........but it's been known for many years that boost ports built from epoxy will not stand the test of time.

If you can make that go I will buy you a 6er of Ohio finest Erie brew.

Work blocked everything now. Guess they want us to work and pay attention.

Some would consider finger ports a race saw only thing. Everyone builds their saws differently though. To each their own.

I think DC had an 066 with fingers and bridge ports that had a lot of hours put on it production logging .

Yep. Tom Fales Jr. Was another one that used finger ports in the poulan pro 475 and 505 back in the 90s.

 

[blsnelling]

I'm not suggesting they won't. I was just agreeing that what is defined as a work saw various greatly.

My 7901 was a work saw with fingers and is out west still cuttin.

I call my old 394 a work saw, u may have to change the piston bout lunch time but that don't take but a minute, there's to many variables and differences in what I or u or anybody calls a work saw. I know a 660 with much more than 200psi that's tuned a shade lean won't live very long in these hills. A work saw to me is less than 200psi has some ignition and will last know different than a stock one, doesn't matter if it's got a pipe hanging off of it as long as it will work all day most days for a year or 2.

Using a spool gun on a jug is a great way to ruin it.

Heat not so easy to control.

I could see tigging channels, would just have to use some type of form that could withstand the heat and then be removed.

That, or using a piece of steel ground into the shape of the port you'd want, then welding a piece of flat aluminum stock over the channel after removing the steel.

 

[mdavlee]

Cut conduit or bend aluminum to desired size. Tack with spoolgun. Make lots of small welds not very long at all.

I wonder what kind of epoxy that is, and how the cylinder is held down. I'm assuming that he simply cast in the entire area, then drilled access holes for the cylinder bolts. Filling in the entire area likely made the epoxy more stable.

Guys been using it for awhile now Brad. Dont remember name as I got out of that stuff. Way better then the JB way.

It might come to me and Ill let you know, but right now not recalling.

 

[mdavlee]

It doesn't look like devcon. Could be belzona. Stuff is supposed to be the best for heat. Rick used it on exhaust ports on 2 stroke boats.
