Return of the Shaper

[IanTParticipant @iant]

Raining hard here tonight, so I didn't really feel like a trip down to the Shed. Been meaning to do this job on the Acorn 7" but (given the interest in hand-shaping) decided to try the Adept instead. It's a 'V' rest – used to hold stuff on the cross-slide a bit higher than the T-slots but not as high as an ordinary 'V' block. It's had a hard life and is not a precision tool – just a work holding device…

​Just over two hours later, half way there – bottom, end and side edges machined – leaving the top angled surfaces to do. Could have done it faster on the mill but they are down the Shed too! Listening to the radio (mind in neutral mostly) it's better than just watching Poldark (which is what the wife did tonight). Hard to explain hand shapers rationally – don't normally do anything too large with mine but this lump turned out to be very free-cutting, so it wasn't hard work…

I've put a few more photos of this job in progress in my 'Adept' album if anyone is interested.

Time for bed!

Regards,

Hi all, if you wish to perform intermittent cutting with TC tips on shaper or lathe the grade you require is S6, a plain ie uncoated tip, I have machined many sets of soft jaws on manual & CNC lathes up to 22 inches in diameter & it doesnt get much more interrupted than that! To reinforce the wisdom of being able to use the same tooling on lathe & shaper I have a V point 55 degree rhombic lathe tool taking positive rake tips, I shaped the width of the shank down to fit through the toolholder on the shaper many years ago followed by making a dedicated toolblock to fit it on the lathe, using the shaper naturally, the time taken to switch it between machines is measured in seconds & by swivelling it left or right its area clearance (technical term) capabilities are astonishing, yes it really can shift some stuff.

Cheers Bob.

This is a nice video showing the action of a larger shaper. Turn on the sound

[Thomas StauboParticipant @thomasstaubo12021]

And this is my small shaper. It has 200mm ( 8" ) capacity.

Nice finish Thomas – and I enjoyed the music too.

Wiping swarf off with a bare hand?

Nice one Ian!

To clarify, the first video I posted titled "Whipp shaper" was not mine. I just think it was a nice video with appropriate music

The second video is mine.

Wiping swarf off with a bare hand?

Got a problem?

It was soft aluminium, and not very fine chips. A chip brush would be better though, and I would use one on sharper chips especially.

Nice shaper Thomas,is the feed 180* out ie it's feeding on the cut stroke instead of the return stroke? .

Only that I was concerned for your hands!

I would have finished the 'V' block tonight but realised I'd made a daft mistake when setting the edges up, so they are parallel but slightly out from 90degrees to the ends. Of course, tonight I used one of the edges as a datum to cut the 'V' – so it too was at a slight angle to the ends. Not the end of the world and I was tempted to just let it go but I know it will just sit there and really annoy me (or come back and bite me again some day when I'm in a hurry and don't remember it).

So I've re-machined the edges true and started to redo the 'V' to get it aligned correctly. Fortunately it's recoverable as none of the dimensions involved are that critical. As usual – not the machines fault – just the dumb operator.

Ian, that block looks useful for all sorts of things.

Would you like to do me a brief write up for MEW?

Morning Neil,

I have used 8mm square lathe insert tools with 9mm triangular tips on my shaper. And got a really dreadful finish after a couple of strokes. The problem wasn't damaging the edge, just the little screw coming undone allowing the insert to move. I couldn't do the screw up tight enough to stop it loosening – I think it was the return stroke that was doing it. I imagine brazed tips would be OK, but use HSS instead.

Richard.

Also some of those torx screws aren't great quality and start to cam out without much use, especially the smaller ones.

[OuBallieParticipant @ouballie]

Don't use it anywhere near often enough for my liking!

Tool bits sorted long ago as this is an old photo.

That sandblasting cabinet now resides in the Carport doing stirling work.

Geoff – Another week to fortnight before left foot has repaired itself, meaning frustration is at the 100% level.
