Wasn't this a Sticky at one time?

Yeah, there was a big debate about unsticking it. Some people didn't appreciate having to trawl through thousands of posts to find the one they wanted. As for myself, I tend to read everything from start to finish, so this was a non-issue.

I just wanted to say "thanks" for bringing this thread back up to the top. It's the reason why I joined in the first place.

Plus - some of the pictures were on the posters own servers, and some of those people have left the forum (like Evan, who posted a LOT of pictures). Others have died.
The pictures can now be hosted on/by the forum itself (but still, not everybody does that), so the problem should be greatly reduced going forward.

Welcome Aboard Dan!

A lot of the missing pictures from the early part of the thread were hosted at Photobucket by a lot of us. And when they drove us out with their sudden attempt at a cash grab a lot, like I did, deleted our accounts along with the pictures. But sadly it left the old threads like this with no pictures.

Welcome to the Forums, Dan! I think you'll like it here. Most (not all) of metalworking math is the usual +,-, x, and divide (don't know how to type that symbol), and a goodly amount of trig and geometry. You will likely find out anything you want to know here. We have some very capable (and culpable) forum members. Some of the pictures have been lost over time. We will never get those back.

I'm continuing my education by going through this thread slowly, but even after being logged in I can't seem to see some pictures. For example, I'm sure post #234 has a picture but I can't see it.

Thank you, Bob. Here is a Rube Goldberg setup I used to make the aluminum base for a wood lathe Longworth chuck. (not pictured because it's wood!). I have it set up on a vintage Fox Supershop. The chuck on the indexer wouldn't open far enough and the jaws don't seem to be reversible, hence the double chuck routine. This was for me a milestone transition project....my first (relatively) precise venture into machining in spite of having much of the tooling. My "training" consists of 3 years of watching expert machinists where I worked as a computer programmer. There wasn't room for the X-Y table so positioning was the "loose bolt" method. Only one position was needed for the ring of holes. I loved using that old indexer...the math is intriguing to a math major. The plate itself and the dovetail mounting step (for a Nova woodturners chuck) on the back was done with (ahem) woodworking tools. The fun part of being this ignorant is not knowing it can't be done this way.

... Do I have to be logged in to see the "missing" photos? ...

Yes

New to this site and have learned greatly from this thread. Thank you to all for sharing. Lifelong woodworker venturing into metal with a fairly well equipped metal shop for small stuff. Question: some posts refer to photos but they do not seem to be present. I wasn't logged in at the time. Do I have to be logged in to see the "missing" photos? I see all the Photobucket stuff and many that are not. Thanks in advance for guidance. I have a few things to share here as I get better at this site.

Size comparison with the original lathe chuck.




Lathe chuck fitted on the Bosch lathe.

[Bruno Mueller]

I purchased another Bosch lathe last year.
The problem with the machines is that there are no more original lathe chucks. The manufacturer of the chucks, the company "Röhm-Spannmittel" still produces this small size, but not for direct mounting to the Bosch lathe.
A good and inexpensive alternative are the small lathe chucks from the company "Sanou". Especially the version K01 -80B. However, you also need an intermediate flange.
I have made a mounting flange for such a lathe chuck for the Bosch lathe.
Here I show some pictures of it.





This is the lathe chuck.


The back side with the centering receptacle of the lathe chuck.


The lathe chuck has a very small overall height.


This is the mounting flange to mount the lathe chuck on the Bosch lathe. The mounting thread of the lathe is M14 x 1.5mm. The centering shoulder has Ø 16mm.
The flange was turned to fit the machine side. The mount for the lathe chuck was pre-turned and only finish-turned on the Bosch lathe.
This ensures absolute concentricity of the lathe chuck.

The long vertical part that holds the Renzetti part... if you mod it .. might have to move hole up.. you can make it clamp with plastic element on either side.. Then, with the right drag on it , it has swingaway capacity... if the indicator body runs into anything..

[ATW]

A solution to angling the indicator was within arms reach - just needed the light bulb moment to realise it - the ball joint from my Robin Renzetti indicator stand can be utilised to provide an extra degree of freedom to the indicator:


754 yes the indicator is likely to be the weakest link, so got to be careful.

[754]

I got very used to the Indicol holder. I think one advantage it may have is if you set up wrong and run into something, its not so stiff... it will move out of the way and fold up, or swing sideways... might save your indicator.
this type looks like very little give if you crash it?.
