Wanna learn to Port a Saw

[paragonbuilder]

How do I sand the base with the cylinder extension?

Will a belt sander and slow rotation work?

Also, "cutting the band". Can I do this with a wood chisel? Then sand afterwards?

Seems a bit more complicated than I thought originally.

Yes. It can be done this way. I heard it on the interwebs...

Got the basics laid out

Gonna go 1/16" up on everything . My big bit won't fit into the dremel . I'll have to finish it with the smaller bits and a lot of sandpaper.

Looks like your off to a good start.

Are you able to record any of this ? Like cutting the base Iam having a hard time figuring it out my self.

Just sand that cylinder extension off. With the bigger jug maybe the extra case capacity will help torque! And it'll be easier to check the base for flat when you are done.

I see there is a bigger piston and cylinder made for this saw. The 272 cylinder has a 2mm larger bore. This saw is 50mm.

Got a buddy who's gonna dig through the pile and see if he can come up with one for me.

There are aftermarket 272 cylinders available at a reasonable price on eBay. Thoughts?

How big should I make the ports so it runs better?

You might need a different top cover if you go with the 272 cyl the plug angle changed a few times in that series of saws.

Doesn't it stabilize the piston at BDC?

Would be alot easier if I could cut it off.

If I'm careful, can probably take a saw blade amount off the base in one cut.

Where's the hoof rasp?

 

[mdavlee]

Drill press and rotary vise and end mill will do the base and extension.

.

I've heard a hoof rasp will work in a pinch.

Are you sure the saw even runs as is before you try to make it run moar betterer?

 

[Whiskers]

Oh yeah, don't forget to bevel the ports! Don't want to hang a ring.

It's just aluminum... throw that jug on a miter saw with a carbide blade and cut the base. You don't need those extension wings, those are just to keep us simpletons from modding our own saws. Be careful though sharp things are dangerous, don't want to loose a hoof.

I'm warning you one last time.
