What's Paul up to?

[PaulL]

I've been doing more work on the bandsaw. Now that I have a 5HP motor, I needed a pulley.
Fortunately I had this bar of 6061 hanging around that I picked upon speculation some time ago:

Then a 4-jaw face-off:

And before losing my starting faces, which are square enough for my purposes, I dropped in a set of tapped holes to drop some square-ended set screws to engage the keyway in the motor shaft.

I added some indexing faces so I could drop the pulley on a set of narrow parallels in a vice. These are exactly opposite and perpendicular to the tapped holes in case I decide I want to remachine the holes or set it up in a shaper for a real keyway.

For now this will do to get a belt length measurement off to Jack Forsberg to make me up a flat belt. I'll post some pics of the final setup when I get the saw going!

That must have been a heck of an interrupted cut!

That was the least pleasant hour of the project. Whup whup whup whup...clench clench clench clench
Removing the 1/2" I left on to hold it was similarly annoying, though with more experience it was less terrible.
I forgot to mention that the pulley is getting some belting spray-adhesived on as a tire, so I'll be adding the slight crown with a strip of tape under the belt.

I think you could crown the wheel with a 1º cut on about a 1/3 of both sides then smooth it in with sand paper. I've done that with a wheel which turned a belt.

Yes, I certainly could. But as it's getting a tire it seems easier to dress the tire. Or just throw a thin line of tape down the middle before gluing on the tire.
And if it doesn't work? Put it back on the lathe and crown it!

Travis at Wroughten Art dropped off a laser cut package for me a little bit ago:

My welds putting it together are embarassing, but adequately structural. The design is nice - all the tabs have little cut-aways, so your welds are automatically recessed. You know, except for those I *really* screwed the pooch on. Hope to get some legs on it tomorrow or Tuesday.

Just look at those laser cut parts! WOW. The hell with a plasma cnc I know what I want now. How many watts do you need to cut 12mm steel? is that 12mm? and it's not just some hot rolled mild steel. What is material? is it treated?

This one is only 1/4" - for my use that's adequate. It's Hot Rolled Pickled and Oiled (HRPO) steel.
He does offer them in up to 1/2".
Serious power for the laser, I'm sure.

Just a tip...lots of pieces of old round baler flat belts laying around farms now that can be used for short "new flat drive" belts. Susq or one of his neighbors could have a suitable piece laying around. The alligator jaw joining clips can be had at any farm supply.

used a piece to build a new belt for my Hendey Lathe, any length or width you desire, easily cuts to width in a wood bandsaw

I'm far enough from farm country to make this harder than it might look!
I don't mind sending some business Jack's way. I enjoy his woodworking machinery videos, and he's been plenty generous in time and advice getting a decent drive on my bandsaw. And I'm not particularly financially constrained at this level, so I'll spread it around a bit.

You might talk to the Saanich Historical Society to see where they get their flat belts.

I've been meaning to visit there for some time (oh...going on 25 years now), and they are open since May 1! Well, time to drop by on my next trip back to town.

What about these?

Yes, they all exist. But sending a few bucks to Jack, whose prices are competitive, seems like a better thing to do.

I have a stack of old baler belts sitting around looking for a new owner and a purpose to do.
