Thread: Don't you hate it when...

Bet you won't ignore the combined wisdom next time!!!!

Nice result. Beautiful grain>

How did you find it to sand?

i have a theory on why this happens . course i could be wrong . and it wont be easy to explain without diagrams but , when you are using a chuck in that way on a dove tail spigot setup if you keep cranking the chuck up real tight i rekon the spigot pulls into the chuck because of the dove tail taper , now it can only pull in so far until the bottom of the bowl comes in contact with the jaws from then on any more tightening of the chuck is trying to pull the spigot section off the bowl its self , or pull the spigot in and push the bowl out , probably depends on how much angle is cut on the spigot dove tail , then depending on the grain direction , i think if the grain is parallel to the face of the chuck it will split quite easy.
kind of the chuck jaws are working as a wedge to separate the spigot from the bowl .
what ya rekon good theory or load of rubbish

Thanks Guys, and no won't ignore collective advice in future .

Hey Texx you might be onto something there.....I can see the theory, but if this was the case wouldn't you hear about this happening all the time on softish kinds of woods?

Artme, sanding was a b*gga, in fact after I posted the above photos I spent a bit more time finishing it (photos are unforgiving ). I turned away the chuck marks on the spigot and had another go at sanding it a bit more and waxing it. But even now, at the areas of end grain. you can with a very gentle stroke of a finger brush the endgrain one way or the other, with a resulting lighter or darker appearance, depending on where the light is shining from. That's OK though, I can live with that..I think.
Cheers

If the dovetail angles matched and the jaw face was properly against the bowl bottom the spigot shouldn't have gone anywhere.

Cedar's so soft it doesn't surprise me that you snapped it off. And it's a sod for tear-out.

Onya for persisting.

At casa del Ern it would've hit the wood pile.

on the sanding thing that is the very reason why when i built my lathe i had it wired for forward and reverse , and for the last few sanding grits i sand with the lathe spinning both directions ( not at the same time of course ).
it helps when sanding some woods ,helps stop that furry finish that you get when the fibers are all laying one way kinda

Yep, I've heared about reversing for sanding and in fact a reversing switch was thrown in when I bought the Leady.

But, I might wait with hooking it up, I've heard Santa may have a variable speed drive somewhere in the bag......

Top marks for perseverance .... and workmanship. Well done GoGuppy.

Sounds like it was a useful experience all round - you get a nice bowl at the end, and have a couple of learning experiences along the way... Oh, and a couple of people on the forums got to say 'I told you so'

What more could you want from one block of wood

Cheers,

Re reverse sanding, just reverse the direction of the power sanding disc if that's what you're using.

FWIW with fluffy grain I've found that more is often needed. Water, oil, wax or sanding sealer; sometimes one of those as well as hand sanding.

Yep, agree with this and did all of that... and as I said it was a b*gga, but am reasonably happy with the end result.
