    Default Luban plane blade adjustment

    Hello, i have a Luban #5 hand plane, that i pulled out of storage to use, BUT when i went to plane with it i had no blade protruding from the mouth (yes there was a blade in there).

    I thought "blinking" thing whats wrong here, i screwed the blade down nothing, so i moved the frog, no luck blade hit the front of the mouth or was too far back.

    Upon closer inspection I found the back/top of the chip breaker slot/hole was hitting the brass screw that holds the cap, now i had the chipbreaker set only a smidgen from the blade edge, as recommended by the forum gurus.

    I cant remember using the plane with any success before, i know i had trouble when i first used it and put it away and grabbed the 4, thinking i will get back to it but alas i forgot until i needed it the other day.

    Has anyone had similar with the said brand? i emailed the Melbourne seller i brought it from, haven;t heard back yet. 5 year warranty on any defect! i hope.

    Now no affiliation BUT i notice Wood River planes (same as Luban) sold by Jim Davey are checked and tuned by him, so i might give him a call to see if he has an answer. I can understand if he doesn;t want to help as i didn't buy mine from him.

    I just had a look at my two Luban planes. A number 4 and 5. They are both setup similarly with the chipbreaker set about 0.3mm back from the cutting edge. They both have about 2.5mm of clearance between the hole in the chipbreaker and screw. That is with the blade in position for taking a fine smoothing cut.

    possibly the issue is that too much material was removed from the leading edge of the chipbreaker when they ground the bevel

    You may have got a chipbreaker that is a tad short from edge to adjustment slot. The answer may be to file out a bit of the top end of the screw slot. Only need enough for the blade to advance enough to take a shaving. I have had this problem using chipbreakers harvested from other old planes. If it is only a smidgen short of cutting then a few file strokes and its right. If it needs more than say 5mm then I would look for a new chipbreaker as its then getting a bit close to the blade holding screw. Of course if warranty is an option grab a cap and blade that fit.

    Thanks John, that may be my only solution filing out the chip breaker hole upwards.

    I rang Jim and he was very helpful, but what he suggested didn't work he did ask for photos, so i will send him a few, i will also post them on here to help others, when i get a spare minute over the weekend.

    Just a heads up Luban and Woodriver are NOT the same beast, Jim said WoodRiver keep improving their planes ie i think they are up to V3.

    Where as the Luban are a little behind, V1 bench planes, V2 block plane.

    i would highly recommend getting planes from Jim, as mentioned he does the fine tuning for your new plane, they are not that much dearer than the Luban.

    Don't think i will hear from the Luban seller, but you never know, the Luban seller also stocks Clifton ($$$$)and Axminster rider planes ($$$)

    I hope things work out soon. It's a pain in the @#$e when something new does not work as it should.

    I can recall this happening with a member with a lie Nielsen. It turned out the blade adjustment wheel shaft had come loose and was moving in and out instead of the wheel. May be worth a look.

    Hi Jazzy, thanks for that, it checked out ok, but it wasa good point.

    2 photos, the gap between CB and Blade.

    DSC00567.jpg

    Plane is sitting flat and the chip breaker is touching the screw, NO the blade is not touching the timber, hope that makes sense, still haven't heard from Fine Tools?

    John suggested: You may have got a chipbreaker that is a tad short from edge to adjustment slot. The answer may be to file out a bit of the top end of the screw slot.

    I suspect that the problem lies with the lateral adjuster slot being too high on the chipbreaker. This prevents the blade/chipbreaker from being wound down enough.

    You can test this out by setting the chipbreaker back from the blade edge by about 3mm. If you get 3mm more extension, then you know the slot is too high, and you either need a new chipbreaker (with a lower slot) or you can file the slot at the lower edge (this will increase backlash, but what the hell ..).

    Stevo, you certainly have a problem - the business end of the chipbreaker seems to be more or less in the right spot and that retaining screw is definitely not going to budge! I reckon someone picked up the wrong chipbreaker when assembling your plane. Chances are, even if you extended the screw slot, you'd find the slot for the adjuster cam is in the wrong place, too. You don't have a lot of room for error with it, 1.5mm either side of optimum at the most. So even if you extended the screw slot, it's quite likely you'll have the adjuster wheel wound off its stud before you get enough blade exposure, or you will manage to get the blade out, but the adjuster wheel will be really difficult to turn because the cam is operating outside its intended arc and binding on the upper edge of the slot (I learnt all this the hard way, making my first replacement chipbreaker! ).

    I wouldn't advise you start mucking about with the chipbreaker until you hear from the seller, I think this is clearly a case of goods not fit for purpose. Send them the pics you just posted & they should readily accept there's a problem not of your making!

    Cheers,
    IW

    Hey Derek, what you drinking, old buddy?? The lateral adjuster engages the blade slot, it shouldn't touch the chipbreaker - did you have a brain-fade?

    Moving the chipbreaker back several mm might allow him to get the blade to engage, but it rather defeats the purpose, doesn't it? My analysis is that both the slot for the cap-iron screw and quite likely the depth-adjuster cam are out of whack..
    Cheers,

    Cleary not enough, Ian my friend! I have a couple of cold beers waiting for you

    However, I think that the shoe may be on the other foot this time

    Here are three blades and chipbreakers: Veritas, LN and Stanley ...



    As set up here, the LN will not work on any plane but a LN. The situation is the same as the Luban in this thread. If you look carefully (squint, dammit!), you will note that the LN lateral lever slot is about 1/4" higher than the other two. All is well when the LN is substituted with another make, even Clifton is the same as Stanley and Veritas/Lee Valley.

    I also note, now that I look at this picture (link) that the Luban and LN have the design for the chipbreaker. Recall that the original WoodRiver/Luban (MkI) was a direct copy of the LN. Guess what that suggests?

    Regards from Perth

    if the 4 is a Luban have you gotten both blades out and laid them side by side to see if the heights of the chipbreaker slots are at different heights? Does the blade from the 4 work in the 5?

    But, but, Derek....

    Are the 'slots' you are referring to in the Cap-iron or the blade? The slot in the cap-iron is for the depth adjuster, the slot in the blade is for the lateral adjuster. The lateral adjuster slot in the LN obviously doesn't go as high as the other two, but I very much doubt it would have any bearing on the depth setting.

    The slots for the depth adjusters appear to be at different levels (by exactly how much is very difficult to judge from your pics because of the perspective) and yes, absolutely, that is a critical dimension, as I've agreed - it only need to be off by a couple of mm to affect blade depth adjustment, so if they are different by 6mm that would certainly throw things way off....

    Cheers,
    IW

    Thanks for the replies etc, i have just heard back from the Seller and he has contacted the factory, so i hope i can get some answers, or better a replacement.

    Pulled both the 4 and 5 apart to check holes, slots, gaps (sound like a gyno) i can't really see a huge difference, chip breakers seemed very close. But i will double check everything.

    It is beyond frustrating, there must be a logical answer - i am missing it, i even went so far as to compare bed thickness, thinking the 5 was thicker in the base, just thinking outside the bubble.

    Perhaps it is something so simple its stabbing me in the eyeball

    The measurement (using a steel rule) from the back of the screw hole in the chipbreaker to the leading edge of the chipbreaker is 70mm on my #5 Luban.
