At the moment my left hand is bleeding.

I had to stop with this bowl (actually, inside of a box) last night because it had a crack, so I superglued it and left it overnight.

Now I'm trying to sand it so that it doesn't have a superglue stain on it - and concintrating on the inside of the bowl instead of what my left hand was doing, SOMEHOW managed to connect my left hand with the spinning chuck.

Got me just under the thumb on the palm of my hand, and we don't have bandaids! So I won't be able to sand it more until I find a glove or something.

We are a dedicated bunch, aren't we? it's not 'OH MY GOD I'm bleeding get me a bandaid!" it's "OH MY GOD I'm bleeding - I might get it on the finish!!!"

heehee

Anyone want to give me some lessons on how you finish off inside a bowl - shaped like an inverted cone.

I've been putting what I learnt about the scraper to good use (yay, I can now use a scraper!)

maybe these will help, get an extension while your at it and fit the lot to your pistol drill

~grrrrrrr~

I DON'T have a piston drill!!!!!!!!!!!


LOL

Actually, I got it done. Just used the scraper to take off high points, then sanded A LOT! Bleeding hand and all :)

down to Bunnies and get a XU1 they are around $16.00, mines being going for nearly three years.

i can visualise how hard it would be to sand inside a box. Hope your hand feels better :) take care of them cause it'll be hard to turn without them.

Place a whole string of swear words here...

It's good that I don't like the shape of the box (which changed over time because of the cracks!) because I failed to catch it as it was cut away, and it has a bit chipped out on one side, and a gouge in the other!

I guess this is eduction, right?

~sigh~

Hughie, the only XU1 I could find on the internet is a car! lol

I don't think that's what you meant!

:U you got that right, Bunnies have a real cheap range of electrical tools called XU1.They are ideal for power sanding etc and at under 20 bucks what the heck. :2tsup:

I think they're a flat navy blue plastic with white writing on the side, Hughie?

The XU1 range of tools are not always in stock, they are a promotional range. You'll see heaps of them leading up to Fathers Day and around Christmas time, the perfect prezzie for the kids to give dad, too bad he wanted a DeWalt or Millwauki :doh:. Apparently Aldi also sell some cheap electric tools.

I think that the title of this thread has been used before, however the content is different. My wife thought the comment about bleeding on the finish was appropriate, quilters beleive the same when a needle goes through the finger!!!

Power sanding helps, however it is not the answer to everything. Being able to reverse the direction of the rotation of rotation helps a very great deal. Mike Mahoney believes that you should reverse the direction after every grit, that is probably a bit of overkill but if you are having trouble with a spot it can work. Another bit to watch is both harmonic distortion (the speed you spin it at distorts the bowl and can "hide" a pocket in a bowl from sanding) and thermal distortion which can make sanding some bits difficult.

I often just bite the bullet and sand the tough spot by hand - good old back and forth elbow grease gets rid of a bad patch a lot quicker than you would think :2tsup:

I don't think my lathe will turn in the other direction. :(

For little boxes where you can't easily get your hand in (I've lost count of how many times I've tried sanding with a little scrap of paper barely held between the tips of two fingers. :sigh:) then you can cut up old rubber thongs (the flip-flop kind :rolleyes:) and wrap the sandpaper about that.

I always sand from the back of the lathe. It feels more comfortable to hold the paper on the top of the turned piece with the timber spinning away rather than from underneath as in the conventional method. Probably got a lot to do with being a "south paw". I can't sand inside a bowl or any hollow form with my right hand so I go around the other side of the lathe and sand with my left. "Conventional" is just another word for "Normal". So, what is normal anyway?

I once made some bowls from turpentine, they were thin when finally finished and were interesting to sand. You could actually see the speed distortion in the rims, speeding up and slowing down the lathe altered the wave form on the rim. Just slowing down the lathe generally fixes this one. I agree about the hand sanding, there are times you just have to do it. It is also a lot less detectable than most would think.

One good with hand-sanding is, if you sand along the grain, you don't usually need to go down to as fine a grit as you do when power-sanding - which is usually across the grain.

When hand-sanding I can often stop at 320! :2tsup:

I usually only sand the little rough bits smooth then go back to having the lathe on. :shrug: I haven't done end grain bowls yet though. Tommorrow's project at 's. (Seein' everyone else is starting early.:p )

There's a BIG difference between starting early and just... "practicing." :~

:(I promise I'll only use his lathe. :whistling: My tail stock doesn't line up AT ALL. Waaaaaaaaaaaay out. :rolleyes: His chisels prolly won't help much. :doh: And I won't ask him many questions. :D Usually I know I'm doing something a little "unorthodox" by the way he wanders over looking intently, and raises up on his toes. The effort it takes for him not to say anything is immense. I then have to make him a cup of tea. :D
