Where to get a new red Dorian QCTP lever ball?

They do not disclose the freight cost, but state that applicable freight costs will be added. Don't know how much they might charge, but ordered anyway. I'm tired of searching. They did allow purchase of just ONE. The listings I found at McMasters said minimum of five. Guess I was looking in all the wrong places. :distracted:

Thanks.

It may be different for everyone but they usually only charge me $5 & change for shipping for packages that are not oversize for UPS. For shipping tubes when I order 3ft rod stock it's around $7. And they arrive the next business day.

As said they don't over charge on shipping so Mcmaster is about the only place I buy from on a regular basis where I don't mind not knowing the shipping costs prior to ordering. I'm sure they get excellent rates & they pass on the savings unlike many others.

I love Mcmaster for that. There's vendors out there that charge $18 shipping for a pack of screws!
 
Do as I do. Order a dozen of the knobs plus the red one you need. So that way, you get your red knob along with a bunch of them to put on the holders that you use with the QCTP. I've probably bought over three dozen knobs from McMaster-Carr over the past 10 years just for this purpose along with replacing missing or broken knobs on the machines I have bought in the past years. Oh, I hate golf balls. Ken

Wow, never seen that done before. What a cool original idea!

I picked up on this at a machine tool auction many, many years ago. They had several lathes with tooling, and the tool holders had ball knobs on each of them. And it's been habit ever since then. Only two places where they are not practical. One, on AXA size tool holders. (I guess you could if you wanted) and second, on DA and EA size holders. Those, you just about need a jib crane to handle, and I don't miss them one bit! Or the lathes that had them!
 
I have BXA so they're not heavy but I can see how that may be handy for larger holders. Maybe I'll try it one day. I just grab mine from the height adjustment collar.

Only other "mod" I've seen on QCTP holders is replacing the adjustment lock nut with a threaded shaft collar. I thought about doing the same but I haven't had an issue with my adjustment collars spinning when tightening down the nuts.

Will, one of the problems with picking up the holder at the height adjustment collar is getting your finger pinched. I bet you have done that a time or two. I know I have.

Actually it hasn't happened to me (yet) but thanks for the heads up, now I'm aware. The ones I use the most are sitting on top of my head stock. All my others are sitting in a work bench drawer next to the lathe. I pick them up by the collar but when I place them on the TP I use my left hand with four fingers on the bottom & the thumb on top.

I should have said I pick them up by the stud, the threads are a little harsh on your fingers! Especially the groove for the lock washer.
