Lately I have had a rash of no name cues that needed ferrules. I have been using Juma ones but no matter what I do they come out like the picture and I have to sand the heck out of them to get them smooth. I tried new cutter, higher and lower speed and no matter what I do, they come out like the picture. I need to purchase some more ferrules and looking for recommendations?

Thanks,

How's your cutter?
Is it loose?
New, inexpensive cutter?
Feed rate?

Turning too slow and feeding too fast , and taking too big a cut could cause that.
My 2 cents,

You didn’t say what lathe you use, but to me it looks like a dull cutting tool is at least a part of this. I use a Cuesmith lathe and cutting tools from Chris Hightower. Start with a sharp cutting tool, adjust the speed and feed rate accordingly and the problem should diminish or disappear. JMHO.

I'm using a Cue Companion. When you say feed rate, are you doing this by hand or do you have an auto feed. I used a brand new blade and got the same results.

Not a real cue maker. But done some ferrule, tip and have built a few shafts. Question why have a tip on one that ferrule is being replaced YET? I would tenon shaft ,place ferrule material,CENTER DRILL small divot so live center runs smooth. Bring ferrule to required mm. A tip very easily will not run true if using a live center.
Depth of cuts close to tip are finer then those near the shaft end. Likely hand feed rate cross slide a bit to loose ?

Mike and others are the experts just a few thoughts here. I may be wrong and certainly won’t object to any schooling in my direction.

Edit: I just t read Cue Companion so hand feeding rate.
I have a powered lead screw on my CueSmith �� that I added a 3 way switch to feed left/ right or stop.

I despise inserts. (for wood or esp. plastic)

Having got that out of the way :D

Assuming it is a sharp positive rake insert with some small radius.....

Do you have the center height set correctly?

Inserts, if set even a little too high, won't cut. But the corner will still plow soft materials like plastic.

If set too low, they will cut, but the work may deflect, leading to a different from of roughness.

BTW, typical practice is to cut going toward the chuck for best support/minimal deflection, not away from it.
Cutting out can also pull the tip off or loosen the edges for later failure.
If you have it backed up by a live center and pad when cutting, i retract my objection. :)

Inserts for facing.

That for turning ferrules.

Assuming his gib and cross slide have no noticeable play.

If you post a picture showing the part and the collet or chuck and the tool you are using all in the 1 picture, it will give a better indication as to what is happening.

I purchased these from a reputable source and the said Juma on them. However, I was thinking the same thing.

Thanks some good advice here. I'll pull out and old shaft and try again. If it still happens I'll get some better pictures.

Looks like a combination of wrong speed and feed, depth of cut and type of cutting tool. One more thing, is the point of your cutting tool at center height?

I would ask that you post a close up picture of your cutting tool right up next to your work piece. Then we can see what you are working with.
