Thread: ebony and maple burl cigar with

hey everyone,

i think the cd idea might just work. but i would make sure that you roughing chisel is nice and sharp and wear a face shield for fear of flying shards of plastic. i want to see it when it's done.

laurie

i've thought of the cd thing many times...i have never tried it though because i honestly thought it would be to unsafe.

would glue stick to it.?
would heat cause it to crack?
is having little bits of plastic flying at you safe?
i asked myself those 3 questions and decided not to try...untill i see someone else do it...also i've yet to turn alot of things that i've got to do ( a certain pen collection needs finishing lol. )
cheers

I have some gluing up... I guess I'll soon let you know.

yeah but they're not sharp and dont have the potential to get lodged into your skin

if your glue up broke, and a disc escaped and flew at you at over 1000 rpm i'd imagine the sharp edge would find your arm or something...and i know this could happen with wood to but i'd think it wood be more probable with cds...



cheers

True. I'll be wearing a face mask for at least the first attempt.

Skew i love your honesty. Makes it even more special. you are the best

Aww... shucks.

Seriously though, although I was having a bit of fun with Stirlo, he had a valid point and I wouldn't want anyone to be hurt 'cos I've made light of a situation.

A 52x cd-rom spins at up to 27500rpm and should be able to handle lathe speeds alright... but it's not being whacked with a big stick at the same time. Worse, not all CD's are rated at 52x... 1x's only spin up to 500rpm, so there's always a chance that any randomly selected CD/DVD from my "dead pile" will shatter at lathe speeds.

And the edges are sharp... I've shattered 'em before, although not in a lathe. Full sleeves and a face mask are definitely appropriate wear for this attempt.

Should be interesting Skew but be careful I remember them doing this on Mythbusters and it got a bit dangerous but they had it going at the high speeds way over 2000 to see it it would shatter, I have found the link to the show

Just watch the first 30 sec ya will see what happened to the DUMMY.

From Mytbusters Site: It was proven that a high rotation (in excess of 8,000 RPMs) could shatter the CDs, but the MythBusters could not achieve this using an average CD-ROM drive. Possible physical damage to the CD made shattering more likely.

Sorry Skew my thought is please don't do it.

But good Idea.

Faint heart never won fair maiden. I say, "Go for it!" Heavy jacket, gloves, and face shield should do it.

Very pretty pen, Laurie. Love the wood grain.

Laurie,
Great pen you have created, the angles are what I call a perfect angle, not too shallow or too steep. The Ebony bands are not over-stated and are in proportion of the overall design and the soda can shims highlight the credit card veneers and a nice Maple Burl as well. A pen to be proud of.

Skew,
Don't use super glue It disolves the dye on the disc and does fly apart. I would say an epoxy would be the only way to go. I did rough the sides up before gluing, oh, the face shield idea, that's a good one. I didn't wear one, wish I did Didn't get hit luckily but scared the **** out of me. To get rid of the hub I used a forsner bit in the drill press and drilled them out. Good Luck Skew

Yup, I didn't want to use any glue with a solvent. so used epoxy after lightly roughing the surfaces with 240grit. I've only glued 6 disks together so far, tomorrow I'll check the glue strength and cut the laminates in half, to double over and make a full thickness blank.

To get rid of the hub I used a forsner bit in the drill press and drilled them out.

I ran a chisel around to remove the raised ring in the hubs of the first two, then decided "bother that" and hit 'em with a Dremel and sanding drum.

Then it's just as well my lathe won't go over 5200 or so, isn't it?

From memory, the Mythbusters spun 'em up in a modified angle-grinder to totally ridiculous speeds.... up in the 20-30,000 range, not a simple 2,000rpm. A simple lathe should be safe enough, but I'm still not going to take any risks.

Full sleeves and a face mask are definitely appropriate wear for this attempt.

I have a pair of chairsaw chaps if you want them too!! If they'll stop the blade of a chain saw, they'll stop bits of a CD!!!

The sunlight did it's trick today (not that there was much of it) - I messed up the centre join a bit - the lower one received one over zealous sanding too many and is just shy of in line. Better luck next time. Thanks Laurie for sharing - it was fun AND met approval of HWMBO!

Nice one JD

Brittle some are some are not . As for turning give it a go carn't heart much just wear protective gear incase murphy sticks his nose in .I turned some perspex the other day for a 50mm,2inch picture frame back that jess made for her grandfather the other day. Just dont do it cold about 24degr celcius then it will be a bbit more flexible .and less likely to shatter.Hay Skew dont for get to play ac/dc 's thunder so no one can hear you scream .lol
