Found an easier fast dirty way of doing it because it was really bugging me, this covers 50% of the cylinder

Use the sweep function with a plane on the top surface and cut it DEEP so your full cut depth is achieved at the edges

Then fill it back up inside to your required depth with an extruded cylinder boss and voilla! a perfect depth cut along the entire length

The geometrics of the cut aren't perfect except along the centreline but its a handy workaround

Well done you. That was a tough one.

Had a squirrel and they were still going in May 1993

Doing it in Alibre atom makes the smoke trickle from your ears

I would deffo buy Design pro

Nice solution Jason (my brain only slightly exploded)

Can Alibre Atom now do sketch wrap?

I'm stuck on V25

Looks like an awkward one that really needs the 3D sketching function

Us poverty stricken Alibre Atom serfs can do a workaround by using multiple planes, but it's a slow process

I've done the first plane and cut, then a plane at 20degees(?) would do my next cut etc

All very fiddly

Fixed steadies are awesomely useful once you've made one, especially for big long pain in the neck jobs

Also allows you to use 100% of your lathe bed

And I hope that drawing is an assembly of parts, not a single part

If you want to revolve an extrusion use the circular feature pattern

If it's a cylinder it has an axis you can revolve the profile sketch around

So use revolve boss, not sweep

and start with a simple square sketch, make sure it revolves, then edit the square into the complicated drawing you require

edit: All looking very nice btw

As David says, you may have to break the part down into a revolve boss and then a pattern cut

There you go

Some interesting snippets on youtube but nothing you wouldn't already have found

One picture with a train showed a wheel so it must have been on iron castors before settling upon solid uprights for the train crossing

So much cracking basically means end of life for the metal

At 5.46 the entire boss is trying to rip itself out of the casting so the metal in the metal casting is actually failing to deal with the loads

If he'd fixed it perfectly to 200% another bunch of cracks would appear just beyond his perfect fix

If the machine isn't too old then it's a bad casting

I've seen it with bad steel, cracks appearing magically in the middle of a plate under load

edit: If a lot of users start getting this problem then the manufacturing company has possibly taken the thin-ness of the casting to it's limits to save on costs and vehicle weight

It's also possible that modern castings have a built in design life, making it a consumable, unlike the old days when they were made to last 100 years

Hex heads are tuff, If I have to turn one down I use carbide

Arbour pressed? couple of tons

edit, handy idea btw

I never moved beyond V25

The Indian and kasbah type stuff is always quite interesting, and eye opening

Break through the steel ball surface with a carbide tipped drill, or grind a flat to drill through

youtube stuff needs serious filtering but there are still genuine nuggets amongst the product placement spam

The slicker and more professional canned presentations tend to be the less useful ones

If the guy looks like Worzel Gummidge on a bad day then useful stuff often follows

Maybe the same guys who made my "cobalt drills"

At least one snapped like a piece of glass
