I love the play-dough epoxy dams.

I also have better luck with flat transfer roofs.

if I know i'm going to cut through, I epoxy it first

 

[sunfish]

Speaking of epoxy, I finally got my brain wrapped around the epoxy in the intake to raise the floor.
That's huge, man. Thanks!

 

[redfin]

Great read Scott. Thanks for taking your time to share.

Same goes for welding them, much easier to build it up first, filling in holes with thin edges can easily end up as a larger hole.
I tend to break through on the outer top exhaust side corner and am left wondering how thin it is on the ones that don't.
Might be better off to break through and then shore it up than be running a transfer tunnel that's an eggshell...

Yes, it's much easier to weld the tops of the transfers when there is not a hole in them and plenty of material to attach to.

When you guys do all this extra work ,i hope you get extra compensation for your time vs a reg port job .

not quite right

Do you have a picture of what a desired piston wash looks like?

 

[RedneckChainsawRepair]

Epoxy has been used for years like this. If you can look close at this Marcel Vincent 166 exhaust you can see the epoxy that was used to build the top of exhaust being it was raised so much.

yur saw looks nice Scott, but mine is huskyer

I was waiting to see if someone had any pics of epoxy on the exhaust side. If it can hold there, and on Scotts high RPM crank, I dont see any reason whatsoever to avoid it on the intake.

Thanks Scott, Randy, and Kevin for posting up these pics showing real world use of epoxy in our saws !
I wouldnt have believed it, but I am convinced now.

the only question I have now is ............ whats the better epoxy, JB Weld or Devcon with aluminum ?

 

[mdavlee]

I would think devcon would be better but JB weld has held on lots of intakes and stuff like that.

 

[Mastermind]

I can't say with any certainty. I've used both with good results.

I've built external transfer ports entirely out of JB Weld. Worked just fine.

The Devcon with aluminum is "suppose" to expand and contract at the same rate as the base metal.......that's why I chose it.

The Devcon is very good stuff, but because I get a great price, we use Belzona supermetal to adjust our exhaust and to repair/beef-up our "cut" Mercury 2.5 L drag motor blocks... it also mates very well with cast aluminum

no, it's part of my band saw sharpener

I looked around the shop today for one, but nope

do you like pink?

Devcon F is what is use for that reason too. It has a thermal coefficient of expansion extremely close to aluminum or magnesium. I've never had a problem with it heaving off the base metal.

jake would be jealous

I should have taken that red thing for insurance
