Fascinating. Yes, like the rhythm..... But I'm more interested as to how you got on with cutting that steel rail material with what looks to be old tool-steel tooling with little evidence of coolant/lubricant. And did you resharpen after each pass?
ASMR, but not mind blowingly boring. What are you making with the nice flat bit of track?
Yes, yes they are, in fact if you have one lying around.........ASMR It is now an anvil/dolly for sheet metal forming on the bench, the shape is very useful and they are a favourite tool for tin bashers.
Good question Dee, most younger folk dismiss shapers as slow and redundant, but they're very cheap and can do things a mill just can't manage.
This is what Shapers do to justify their existence, they can take lots of material off rusty unknown old metal with cheap tooling, those are light cuts for a shaper, mainly to prevent the rail being pushed out of the vice, bolted down solid to the bed much bigger cuts are possible at slower speeds.
Unlike carbide, HSS tools will put up with the constant interrupted cut, because the tool is only cutting 60% of the time heat build up is not as much as on a mill or lathe, so the tip lasts longer. The tool tip is much stouter than a lathe tool due to reduced relief angles, which helps too.
Some people keep a shaper just to remove large amounts of stock before putting it in the mill to save time and tooling.
That tool had already done the same operation on the other end, and I didn't sharpen it before starting that but gave it a lick on the wheel before the final cut in the vid, and also put smear of oil on the rail surface.
Those with good hearing should be able to hear the sound is different on the last pass as the machine runs lighter due to the re-sharpened tool.
Yes, yes they are, in fact if you have one lying around.........
Shapers are great at cutting internal keyways. Also the surface finish they leave us superior to the mill. I have my eye on a nice little english made shaper that has vertical as well as the usual horizontal feeds.
i remember years ago snapping tooling going into blind corners or abutments...always bugged me and i think it was this that put me over to a circular cutting milling machine..Dore Westbury i freely admit toMachining into a deep internal corner is another benefit of a shaper.
I know they take a heavy cut but that's got to be about 1/2".Shapers are great at cutting internal keyways. Also the surface finish they leave us superior to the mill. I have my eye on a nice little english made shaper that has vertical as well as the usual horizontal feeds.
