    Default Adventures with my Klopp shaper

    I picked up this Klopp 350 shaper a couple of years ago, gave it a bit of a cleanup at work while I had it stored there, but only recently got it into my workshop at home
    When I first started to clean it up the ram was stuck tight in its dovetails and even after removing the gib I still couldn't move it fore/aft as it was stuck solid to the other dovetail. I had to use a reasonable amount of force to lever it sideways and break it loose. Turned out to be just dried out oil, and the ways themselves were OK.

    Here's some pictures of when I first looked at it.

    Up until now I've only played a bit and ground up a couple of tools, made some test cuts and got a general feel for how it works.

    Time to put it to work and make up some toolholders for the QCTP that I bought from Caskwarrier over a year ago but only fitted to the lathe last week!!

    Squared up a lump of stock (scrap forklift tyne) and started to rough out a recess in the middle.



    Tried out the shear tool I'd ground up.

    Started on the dovetail and was going really well until something happens and the tool dug in, pushed the workpiece half way out of the vice and broke a lump out of the tool







    I'm thinking the clapper might need to be locked for cutting dovetails....

    Couple of shots of the machine itself as it is at the moment.

    Nice, I miss not having my Alba 24 inch shaper, but the little Douglas does the keyways at least.

    Hi Steve,

    Nasty experience that tool breakage. From the looks of the tool it could have had a crack in it, if it had just hit a hard bit it would have taken a bite out of the cutting edge.

    Yes, the way it broke is a bit puzzling. They are NOS HSS tipped tools - approx 25mm of HSS brazed on the end of a shank - so I've no idea of the steel grades etc.
    Hoping not to repeat the performance to find out if it's consistent behavior !!

    The Klopp has an automatic tool lifter on the back stroke but it's been broken in a previous life so it's not fitted at the moment. It's also the lock for the clapper so think I need to get it fixed before going much further.

    Are you sure you have the clapper set to the correct side?(it does my head in trying to visualize it)
    Whats the other end of the part look like?

    I'm not so sure about the way you have the vice mounted, but if it didnt move when you had that crash I must be full of it.

    Definitely not sure about the clapper angle (and can't get my head around which way it should be). I need to do some research.

    I've read a few different opinions on which way to orientate the vice. Very glad it was this way around and the part pushed out or there may have been serious damage not just a broken tool.

    Nice shaper. The tool may have come loose and dropped down causing it to dig in resulting in the breakage. I remember my old Boss destroying a yamaha outboard cylinder head as a result of the tool coming loose on the shaper we had at work at the time and then the same tool came loose on the second cylinder head destroying it as well.

    Nice work Steve, good to see you've got the beast working. You do need the clapper clapping when cutting a dovetail; to set the clapper angle, ensure that the clapper lifts the tool away from the workpiece surface- confirm this by lifting the tool with your finger. It looks like you may have it angled the wrong way.
    I've pushed the workpiece out of the vice once or twice. Not sure what the answer is there, certainly the vise needs to be very tight- they're built big and with a pulling action for a reason. If the clapper is angled so that the tool is dragging heavily on the return stroke, it may have moved the tool and caused an over-ambitious DOC at the entry point.

    Thanks Pete.
    Been struggling with getting my head around which way to angle the clapper angle with the head on an angle. Just had a lightbulb moment and realised that the clapper/head/cut relationship is no different than if the whole head was rotated to vertical and cutting a vertical face.
    So for what I was trying to cut the clapper should have been angled the other way. I definitely had it wrong.

    Will get that sorted, see if I can recover that tool or grind up a new one then take a deep breath and have another crack

    I've cut a dovetail on my shaper too and setting the klapper angle so that the tool is able to lift away from the surface can be confusing.

    Do what was previously suggested and physically pull the klapper out to see if the tool lifts off the cutting surface.... while unplugged of course. Adventures with my Klopp shaper

    Clapper set the right way and a couple of new tools ground. Making good progress with no further dramas so far.

    I've been able to get a reasonable finish on the top surface using a shear tool, but the finish is poor in the dovetail area.

    Any tips from you experienced shaper guys? Particularly when machining old forklift tyne material.
