Well i ordered mine on a Friday and it arrived the following Wednesday last week. Liked most of the articles but the one that interested me was the hand shaper which turned out abit poor in details and pictures( there rubbish).

My chester comet vs can do that too, you can disengage the spinde but keep the power feeds going. Never thought of doing a job like the above tho.

I've been thinking about trying this out too for awhile, thanks dcosta. Time to order some bits.

this thing i made is not pretty but it works. x/y table, tilting rotary table with a er collet block

Hi all,Im on the search for the type of tip arcoeuro use for there face mills, its a triangle type with no hole and 20mm along each edge with 11 degrees of clearance. Can somebody tell me what these are type etc as there site just lists them as size 8. Here's a link to the cutter in question, its the mt3x2 inch one. thanks **LINK**

Went to the biggest steam rally in ireland today at shanes castle. lovely spot. some really nice engines. You name it ,it was there. Old tractors cars, stationary engines. small steam engines and bloody huge ones. was a great day and just to finish things off a bit better i picked up a lathe test bar mt3, looks brand new for a tenner.Ill put some pics in my albums for it.

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?

Humm think i may well have opened a can of worms here 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.

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.

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.

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.

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.

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.

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

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.

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.

No worries thanks, will get some orderded.

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.

The thing i was using five mins ago that has now buggered off never to be found again till i don't need it.
