One more thing
For all new orders, I have 15 sets available for sale, they are all grounded already and sizes are less that .845" so for anyone needing some smaller than .845". My machinist can regrind them to what ever size you are looking for, then I can cut any thread size you need.
Pricing: $295 per set or $575 for 2 sets
Best Regards
PLEASE do not PM me for those mandrels, I have my hotmail account dedicated for sanding mandrels orders only, so please email me to customcuelathes@hotmail.com

no hard drive back up - wow - a major mistake - there a ton of internet services available that could have stored everything

I bought one set for sanding & one set for finishing from Bassel. Other than the long wait, I'm very pleased. Great improvement to my process.

I really appreciate you patience waiting for those mandrels, and same goes to Mark, Richard, and everyone else who was patient and waited all this time to get them.
Best Regards

 

[carguy]

still waiting

I'm a REALLY patient guy. When will I see mine, ordered 3 months ago?
The wait is not too bad but the lack of communication until lately...less good. Everything will be wonderful if I finally get the mandrels and the quality is good. I need other sizes too.

Are your faces flat? If so you had better luck than me. I can screw mine together and see light through the joint. One even has a chip in the face. I guess he doesn't know what size root hole a 3/8x11 pin uses because they wouldn't even screw on a pin and I have pins from different sources. I'm not trying to bash Bassel, even though it might sound like it, but buyers should beware before purchasing these. It was definately amatuer hour when he made mine. I'm so disgusted that I haven't even spun them to check the run out. I guess I have no choice but to just write them off as a loss. Totally useless!!!

If you are so disgusted by them god knows what, send them back, you asked for 3/8-11 and that's what you got, the tap was purchased from atlas, so if your pin doesn't match atlas 3/8"-11 tap, then I don't know what to tell you except that I purposely taped them with an undersize tap first to get a tight snug fit, so when you break them in, they will fit nice and snug. Please send them back along with one of your pins, and I will fix them and match the female to your pin.
I only can work with the information you give me, for example: if your pins are 3/8-11 with 0.308" barrel, you should have mentioned it upfront not blame me for it after the fact. I am not saying your pins are the problem, but clearly from what you have stated, there is a difference. I will email you my address and hopefully we can resolve this issue.

Bassel,
Now that I have you on a public forum saying to send them back, I will. What I don't want is what you offered me in a pm, some of the original batch that you figured out how to fix. Send me your address and I will be happy to send them back. Could you also make sure that they will be tapered like I asked for? If they are not tapered, like the ones you sent me, they are useless in my opinion.
Marc
P.S. A .308 barrel would not even come close to going into that hole!!!

I ordered the Uniloc radial thread with mine. The first thing I did was check the runout in a 5C collet. The runout was less than .002 but part of that could be the way the part is clamped in the collet. I was using a fractional size collet trying to clamp a Ø.835 part.

My Ø.835 sanding set threaded right on my pins. I have sanded out 7 cues now with them. I am shocked at how far off center my pins are before sanding! I install my pins before I final turn my cues so I assumed they were dead on, but dang was I mistaken.

My 2nd set is Ø.840 and guess what, I could not thread it on my pins. Bassel told me he used the undersized radial tap in my finishing set for a tighter fit. If I returned it with one of my pins, he would tap it with the standard radial and take care of it. Instead of returning it I decided to find my own standard radial tap and take care of it. All I had was the undersized radial myself so I thought it would be a good idea to have that tap on hand for customers that do not want a real tight joint.

Once I got the tap I ran it through the finish Ø.840 set and now my pins fit perfect. The only gripe I have is the wait. I work with machining houses quite often & know some things can get out of your control. That is why I took the high road and didn’t pipe up earlier when this subject started getting dicey.

If you can’t tap it yourself then send it back and I think he’ll make it right.

Hi,

Did the dog also eat your homework?

Having a mandrel done and putting it to the market is not something you can do on the fly. You must produce the product, then test verify that they are consistent before bringing them to market.

Get all the bugs worked out, stock, then market.

My mandrels from Rocket are .0002 or .0003 as best as my see on my .0005 test indicator. They need to be that accurate, IMO.

Mandrels are a tricky business, they have to be tool room quality and accuracy.

Good Luck.

(dated 9/15}

Today is 9/19. Still no word? Not an email or phone call or a post on this forum? What happened to "tomorrow"?
My patience is history. This is a tool I would use constantly...I needed it in some reasonable time frame.
Also, .002" accuracy...for a ground part??. I do this well now on my tired old Porper with no mandrel at all!!
Now there are problems with the fit of the screws, the most basic dimension on the device?
And now you've lost everyone's order and don't know what they ordered or how much anyone paid?
I received the live center..it's OK, but I needed the mandrels at the beginning of summer. Guess what, Bassel, I think I'm done with it. It's fall!

******Well, I had asked Bassel for a refund, but I've changed my mind. If I get these things, I will post a review.******

indication

Where did you see 0.002"

[carguy]

.002

DanO measured <.002 runout on his new mandrels. For ground parts I cannot imagine why the runout would be more than a tenth or two if any at all.
Oops, I just noticed that was including the collet runout.
In my experience, ground parts like these come out pretty much dead nuts.

Look, I'm not trying to pile on when Bassel has more than enough difficulties. I have a practical problem: This is a tool I need, it's been way too long in coming, there's been precious little communication, way too many excuses, and now reports of bad fits/low quality. I'm not pissed, I just need to get on with my affairs. It's too bad it had to turn out this way. I think Bassel is an OK guy, I just need my stuff, made correctly the first time, in a reasonable time frame.

*****I've just requested of Bassel that if he sends my mandrels right away, I'll accept them and review them on here. I'm rooting for Bassel! I just need these things yesterday!********

I'm still waiting on that address.

Are you kidding
I PM ed you my address that same day

 

[LGSM3]

Where did you see 0.002"

John

my guess is that they were in a chuck when indicated? Which would probably explain it

Robin Snyder

Robin, if you ground all the surfaces (shank, bushing and thread face) at the same time then yes, they should all be deadballs. More then likely they were rechucked a couple times. This should not add any real inaccuracy but it does compound somewhat. A decent lathe man should be able to do this. If its done on a CNC then its that much easier, the grinding of the carbide should be a piece of cake.

I have no idea what the problem could be or even if there is one. Obviously, the guy who says there is a gap when he puts the 2 pieces together has a problem. It could be simply that the thread mating face needs to be ground perpendicular to the thread/shank. Hard to say without actually holding them. As long as the thread is concentric and true to the shank everything else should fall in line.

I see someone else said they couldn't get the pins to go in. I find that somewhat likely. Just like you have taps from H0 to H5, same would go for the pins. The tighter the tolerances on the mandrels, the tighter the pins will fit.

I can give you a quick way to check the concentricity.

Chuck up the mandrel, spin and get the TIR (Total Indicator Reading)
Loosend the chuck and turn the mandrel 90 degrees.
Tighten the Chuck with the same pressure each time
Get the TIR again
Do this again until you have 4 readings (more if you like)

The differences in the readings would be the total runout. Obviously this isn't absolutely deadballs accurate but it will be pretty close. If the total difference is say .0005 I'd say you're good. If the diff. is something like .006 I would think that was too much.... you'd be .003 off center. I have a hard time seeing .003 any more but I sure can feel it.

Not sure if any of this helps but free advice is what its always been.

R+d

Brupert- Thanks, I noticed it was held in a collet and that may well be the source of the runout.

The idea of having to rework brand new fixtures to make them work, chips on the face, not screwing together...?

I think that in the end Bassel may very well have a good product but it still does not sound market-ready to me. Perhaps I'm wrong.

R+D takes money and time. And more time. But without it spotty results are predictable.

Like art, developing a product is an exercise in problem solving. Getting a great idea is, unfortunately, by far he easy part.

.****...Grumblegrumblegrumble....or, mabe I'm just turning into an old grouch. I've sent Bassel a PM saying if he can send them immediately, I will accept them, and review them on here.

Look, I just need mandrels. Good ones. Right away. If they are great, I'll say so, and perhaps buy more. R ****
