Re: Cutting oversized stock in the 4x6
|
Hi Lee To add to the cut/flip/cut method: 1. Use a bit of 2x4 inside the channel so that the vice can clamp the 8" section against the vice jaws 2. Support the other end of the channel on a stand (I posted a design 24Apr20). Heavy sections hanging over the edge of the saw actually twist the base and affect the squareness of cut 3. Your saw has to have very good vertical squareness to cut it nicely, If the sawblade pings away from the cut after cutting a 2" steel section, or scrapes against it afterward as you raise the saw, then no way will if cut nicely through 8".? See Rick Sparber's recent post on horizontal sawing accuracy for how to check your setup? 4.You can cut upto 10" (250mm) with a 4x6 and 11.4" (290mm) with a 5x6?
Accurate cut/flip/cut is very possible, attached is a photo of 8" wide 1" alloy plate cut through by flipping and just aligning the sawblade?with a scribe mark across the plate. The cut was within 10thou when squaring?up the edge in the mill later.

A couple ways¡..

One, is set up the channel vertically, cut from one side as deep as you can go, and then flip it over and finish the cut. You can keep the cuts aligned by using the work stop, and if the parts you are
cutting are too long for the stop, make a longer rod.

Another option, is to make your own jaws. On my Grizzly saw, I have made several different jaws for different odd cuts. The saw has 8-3/4¡± between the guides, so all I need to do is add a 1-1/2¡± spacer
to the fixed jaw, and I can cut 8¡±.

You'll probably run aground around halfway through when the arm casting hits the top of the channel.

I've been lurking here for a while, but now have a challenge that could use some input. I have a Detroit Machinery - branded 4x6 saw, manufactured in 1981 in Taiwan. My Dad bought it, and I've
inherited it and by sheer luck got it cutting unbelievably well. This saw has changed the game with my DIY/hobby projects, mostly welding.
I would like to cut a piece of 8x1.75" steel channel with it, which I know is outside its limits. The saw will accommodate the channel vertically (on its side), so I'm wondering what will happen
if I try to cut it. I absolutely don't want to damage the saw in any way. Alternatives would be O/A cutting, angle grinder with cutting wheel, or haul it to work and ask the fab shop to cut it on their industrial-grade band saw (I'm already indebted there
with other personal favors).
Thanks for your thoughts.
