Thread: Broken keyless chuck
17/08/2021 07:44:16

I've not managed to fix it yet. I've not even managed to dismantle any part of it. I can't extract the taper from the chuck body, and the rear collar appears to be just a cap, which also refuses to come off.

By holding the tang of the taper in a vice I'm able to app[y a powerful pipe gripper to the shroud, and have managed, little by little, to unscrew it enough to see the start of the thread. Each time I try, there is considerable internal grinding, and I'm able to unscrew it a little more, but not yet enough.

The keyless drill chuck I use on my lathe suddenly decided it had had enough. I had just removed a drill and wanted to insert another, but although the sleeve turned, the jaws didn't move. I can screw the sleeve in and out about 6mm, but the jaws don't move. There's a slight grinding noise apparent when rotating the sleeve, but the jaws remain stationary. There is no maker's name visible anywhere. I've used it without problems for a number of years.

I can't see any way to open it up to determine, and hopefully rectify, the problem. Any ideas?

Did you look at the link I posted at 9:47 on the 8th? (Mod edit the 4th)

How about a jeweller's piercing saw?

Fascinating, thanks Michael.

These were done with my clamp-type tool. Examples in aluminium, brass, MS, SS. and silver steel.

Thread: Problems in bending sheet aluminium to a 90 deg angle
07/08/2021 14:30:56

I reckon that the purpose of the angle-iron is to securely clamp the workpiece, but you are using it as a bend stop. I suggest to reverse the angle-iron and machine a bevel on the edge close to the bending point. Then make a separate stop to limit the bend amount.

THIS is a link to a PDF of one I designed and made many years ago. I also designed and 3D printed a storage box for it and some additional knurls.

Thread: Centec 2B - New arrival and Q&A

William, Re the chrome dome nut leaking. it doesn't seem to do much other than retaining the stop pin behind it; mine leaked too, so I added either a fibre or a copper washer underneath it.

Edited By peak4 on 02/08/2021 12:24:07

I would think that you've overfilled the quill if there's a leak around the dome nut. The quill is the oil reservoir, or have I miss-understood it or all these years? .

I fitted a 3-axis DRO to my 2B and then added a DRO scale for the quill, which is surprisingly useful. As per SOD, I use an edge finder and work from an edge or a centre point (easy to find with a DRO). All my drawings are dimensioned accordingly - I never have use scribe lines or a centre-punch.

"What is the purpose of the nut on the front of the vertical head? It seems to just spin in place on my one."

It limits the vertical movement of the quill, otherwise it would hit the oil level dipstick which does.

2BA grub screws for the gib adjustment on the 2A, as above 1/4 BSF thread for the locks. All the threads on my 2A are either BA or BSF, I assume they would not change for the 2B.

For the Mk3 VH there is a small grub screw, just behind the quill lock handle, that pokes into a slot that limits the quill vertical movement. The nut on the front of the VH does nothing on my VH.

Do you know what thread the halfnut locking bolt will be, or what the gib locking screws are?

Edited By William Ayerst on 31/07/2021 21:22:53

The gib locking screws are 1/4 BSF

The half-nut may be worn so that small side pressure pops it open. I notice that you still have the rapid return spider, so you probably want to use the half-nut properly. I removed mine and keep the half-nut permanently closed.

A slight mod I made to my Centec was to the Y-axis gib-locking screw. It's a long Imperial threaded socket head screw which I found tedious to use. The Allen key kept falling out and I didn't have the wherewith all to make a custom version, so I made an extension from a piece of aluminium that's a press-fit into the socket head.

It works for me and encourages me to lock the Y-axis more often.

What is the purpose of the nut on the front of the vertical head? It seems to just spin in place on my one.

On my VH the nut screws onto a pin which is inserted from inside the VH, so don't push it in unless you want to dismantle it. It's not connected to anything inside and doesn't act as a stop for the quill. I used it as a convenient method of attaching an external stop block when I made an adjustable quill stop.

Thread: 'Puter upgrade recommendations
28/07/2021 11:18:50

I've been using F360 for about 3 years now and I'm reasonably satisfied with the performance on my elderly Win10 Home system using a Core i5-4460 processor, NVIDIA GeForce GT 705, 12GB RAM, and an SSD. But when I watch videos by people like Brad Tallis etc, their systems seem rather smoother than mine, especially when demonstrating things like moving sketch items etc. I'm considering an upgrade to my system, but have limited funds. Any recommendations please?

Thread: Wall Chart

In that case - problem solved. I've learnt something.

Thanks for letting me know.

PS. I don't know why it should take a long time to download, it's only 85KB.

I think I've cracked it. When I created the original post I inserted the link into the popup window when I clicked the Link (Ctl+K) icon. That was it - nothing else. After the reported failures I sent the link in an email to my wife. When I inserted it into the email, a window popped up asking who should be allowed to share the link - I clicked the 'Anyone with the link' option. My wife then opened link with no problem. When I copied the link into the Ctl+K window, no such window popped up. I reckon it should work now - am I right?

25/07/2021 16:56:35

I don't know why it's not working. It says that anyone with the link can read the file, and I can't see any other controls I could use.

Any ideas?

25/07/2021 15:20:38

Is it working now?

25/07/2021 14:29:49

Sorry folks, I tried it again, here's the evidence....
