New Information about the CarveTight Spindle

[lynnfrwd]

LHR continues to improve our products, making something that is already great...even better.

We already know the CarveTight Spindle is a great improvement over the old-style Quick Chuck, but now, by accident first, and then with further experimentation, we have discovered how to make the CarveTight Spindle have EVEN LESS VIBRATION, which also means EVEN LESS NOISE!!!

All CarveTight Spindles shipped from LHR Technologies, whether sold by themselves, as part of the CarveTight Service Upgrade package or sold in New Version C Machines will now have a slightly longer screw to hold the bit in place and two washers on them. Any machines that may have already been shipped to a distributor will not have these.

NOW THE REALLY GOOD NEWS FOR ALL OF YOU THAT ALREADY HAVE A CARVETIGHT:
You can go to your local box store and make these changes to your CarveTight yourself! All you need to upgrade your CarveTight is the following:

M5x20 Socket Head Cap Screw --- qty 1
#10 Split washer --- qty 2

Place the two washers on the longer screw. Remove the existing screw using the t-allen wrench and put the new screw with washers on your spindle.

Now, how does that sound?!

Thanks for the info, Connie. Can't wait to try it myself!

[TerryT]

Sometimes good things are the easiest to accomplish. I'm going to pick them up tomorrow!

[fwharris]

Connie,

Thanks for the update! Sounds very simple!

[jaroot]

Well thanks Connie! I'll give it a try. I don't even really notice mine since I changed to the CT, Now the DC annoys me, but every little bit helps and less vibration should mean more reliability.

One Question for clarification:

M5x20 Socket Head Cap Screw --- qty 1
#10 Split washer --- qty 2

Split washers? As in Lock washer?

EXCELLENT update-- it is things like this - providing the information to improve the product - that will keep folks coming back for more

Good job LHR

I am trying to imagine what Lynn posted.... Can someone post a picture... So we are not talking about the 4 bearings but the chuck itself?

The Locking Screw that holds the bit in place?

[liquidguitars]

sounds like more mass = less air displacment.

The thing that struck me about this "update" was I actually asked this question way back in 2010.

And we all know the rock chuck's are nearly perfectly balanced. I guess we will have to wat for MT to chime in and explain all the "benifits" over LHR or aftermarket chucks out there.

I's sticking with the rock unless there is some REAL benifit to this new chuck. I'd love to see a third party do a static and dynamic balance test on thest two chucks to see who the real winner is.

I guess it took a while, but it would appear that this question has finally been answered. I'm not bashing anyone or anything... at the time I just wanted some empirical data that would compare all the chuck alternatives. Even now, I'd still love to see some data but I understand the logistics of getting impartial data in a way we could all agree was fair and balanced.

the original thread has since been archived, but you can still google it if your want to read the entire thread. Im not sure if it is possible to read archived items directly within the forum.

edit: I was mistaken... the entire thread still exists on the live forurm : http://forum.carvewright.com/showthread.php?15164-New-Carve-Tight-chuck-released...

I just tried this modification. The noise reduction is significant. At least 15%

[lynnfrwd]

Just curious...how much for screw and washers?

Just curious...how much for screw and washers?

M5x20 $0.70 M5 split washer $0.10 each 2 = $0.20

I went with the M5 washer vs the #10 ... guessing that is ok????

[SteveNelson46]

I bought them at Ace Hardware. About $1.00. They also had the M5 split washers instead of the #10 split (lock) washers.

[lynnfrwd]

From what I understand, either will work, but metric was about more than twice the cost.

I haven't heard it yet. Just found out about it yesterday.

The #10 was .09, metric 0.10

[mtylerfl]

Hello,

I went to Home Depot for mine. The Socket Screws were $ 0.70 for a pack of two and the #10 split Washers were $ 0.98 for a pack of thirty.

[lynnfrwd]

Okay, so not much at all. Good!!

[TerryT]

I just did my first carve with this mod yesterday. Significant reduction in both noise and vibration. Heck of a mod for under a buck!

[Hasher]

I received my "c" machine this week from Amazon it did not have this upgrade. It does make a difference.

[lynnfrwd]

Did you order the N01 or the CW005 from them?

[Hasher]

CW005 It had the CT but not the screw upgrade.

[lynnfrwd]

Ok now I understand. Amazon got those machines before we discovered it.

I recently did this mod.....holy smokes.....what a difference!!!!!!!!!

[kroskam]

I just upgraded my machine to the Carvetight 9/13. Does it have the modification, or do I still have to do it?

You should be good to go but a quick check on the screw length will tell you. They made the change in house so I believe all units shipped out after this post started had the longer screws.

[bergerud]

Do you have two lock washers on the tightening screw? The mod was a longer screw with the two washers.

[aokweld101]

I just got back from Lowes got the screw and washers I was headed that way to get pull knobs for my second jewelry box I have three more to go before Christmas.

[55president]

I'll have to try this out as soon as I get my new "used" machine -- my old one is down, still waiting for a new motor.

[CarverJerry]

So I take it that the longer screw and the 2 washers is for weight to help balance the spindle better, am I correct thinking this way? I would think they would have preformed a balance test during designing of this. There are ways to get an item perfectly balanced now days.

I worked at a place for DOE where we made centrifuges that were 50 feet long about 2 feet in dia with about a 1/4 wall thickness, they would spin these at a speed of around mach 3. They used a special computer and machine to put weights (small pieces of foil tape) to get this tube perfectly balanced. Of course they spun this thing up inside of a steel case under vacuum and took hours to get it up to speed.

[fwharris]

Jerry,

Yes the longer screw and added washers helped improve the balancing of the chuck. It did make a difference.
