Thread: new chuck key
16/04/2013 16:03:02

I made one awhile back for my four jaw chuck so i could move two jaws at a time, never hardened it at all, just mild steel, works grand. Should i have hardened it?

Thread: 3 hole pcd
16/04/2013 15:57:59

Humm think i may well have opened a can of worms here laugh but now for the good news, with the kind help of the folks here i have now sorted the pcd problem and made a mounting plate for the grinder. Still a few tee nut/clamps to make and it'll be time for a test run.

15/04/2013 14:48:30

Not sure but in my day (20 odd years ago) when I did my gcse's, we covered none of this type of math.

Some useful tips thanks, should be able to get this sorted now.

15/04/2013 08:31:43

OK thanks all, just to enlighten my post i have a small bench grinder that I'm trying to make a mount for which has three holes at either end for mounting of the to disk guards, I'm going to use them to make a mount to hold the grinder to a shaft so i can raise and lower the wheel/ grinder on a vertical shaft. I'll get some pictures up when I'm finished. Trying to use as many of the shelf bits as possible to keep things easy.

15/04/2013 08:03:50

I know this sounds stupid but how do i work out the diameter  of 3 holes to get the pcd that have already been bored into something? We never done anything like this in school so any help would be great. I'm making a mount for a small grinder to make a poor mans tool and cutter grinder.

Thread: Conjunction of Moon and Jupiter
12/04/2013 19:17:25

Not got the must fancy stuff but it works not to bad . The scope is a skywatcher 8inch reflector mounted on a heq5 tracking mount, the camera is a cannon 350d mounted to the scope on a t-ring. Abit hard to focus as can be seen but works ok. those shots were really 10-15 long exposures all stacked one on top of the other.

12/04/2013 10:04:33

I used to try my hand at astrophotography a few years back before children etc. still have my telescope and camera stuff safely tucked away, but here's a few shots i was quite happy with.2006,10.0220 m31.jpg

Thread: A usefull tool?
11/04/2013 09:48:24

To me it looks like a big scroll chuck, would actually be quite handy at times.

Thread: What did you do today? (2013)
08/04/2013 09:08:12

Trying to machine a new backplate for a 125mm chuck i got as my wee lathe uses a 100 chuck. This is not as easy as i thought it would be, oh well back to work.

Thread: Milling Vice.
22/03/2013 10:15:18

I got the 5 inch one from gloster tooling for my mill, have to say I'm very happy with it. It's not perfect but it didn't cost a grand. There kurt clones and pretty good. The casting is pretty good tho the vice needs a little cleaning etc just to pretty it up.

Thread: Paint
25/02/2013 21:58:35

No worries thanks, will get some orderded.

25/02/2013 15:03:09

Hi all, this might sound like a silly question but what is a good paint for cast iron. I'm making a engineers level from the castings over at ces. I have the machining done but would like to paint the rough parts say green. what's a good paint to stick to cast iron ? Do i need to prime it first.
