I've spoken to lots of members in PM's about lathes, mills and tools since I joined. A thread about tools both big and large that we use in our steam addiction could be fun and educational. I know that I have been given some great hints and help from generous members.

Lets see if this thread takes off, hopefully its popular! (If it doesn't I'm happy to talk to myself and post pics to myself )

To start off -

I made a saddle stop for my lathe and out of a block of aluminium and a stainless steel rod and brass knobs. It's fantastic and has been really useful. The last week I took it a bit further and made it so that I could leave the saddle stop in place and change the stop position by being able to wind in and out the brass cylinder that you can see below that I knurled. The smaller brass knurled cylinder to the left is a lock. It's so simple to change the stop now as I can unlock either the main saddle lock for a larger positional change, or just unlock the brass cylinder lock and spin the knurled saddle lock either in or out. Great for taking multiple cuts to the same shoulder etc

I use my steady fairly occasionally (much more than my follow rest) and did this easy mod that's worked really really well for me. The ball bearing races have made such a difference -

Something that I learnt from Kevin (and I wished I'd known it years ago) was the simple trick of using an ordinary needle in my milling machine to centre perfectly something that's needs drilling accurately. So simple yet so utterly brilliant!

I know a lot of people know about and use Autosol, but did you know that they make a polish particulary for chrome? (also great for buffing plastic).

This is awesome stuff for Jensens and Wilescos and gives the chrome/nickel a mirror like finish -

Are you into Dremel (or Dremel like tools) ? Dremel have introduced an EZ Lock system that is bloody terrific. So many accessories now come that are made for the EZ Lock mandrel system. It takes just seconds now to change from one accessory head to another. If your a frequent Dremel user (and aren't all steamers!!!!) next time your shopping for Dremel heads, check out the EZ Lock system.

I think it's called sticky pin, I've read it in a book somewhere but can't quite figure out how it works could you post a photo of you using it? (maybe if I read it again it would make sense..... that is if we're talking about the same thing )

This will hopefully become a good resource for machine tips and mods

Just my type of thread.

Love the stop you have made but one suggestion put a steel dome on the end that way swarf cant get caught in the gap and change the position.

Both my lathes are gap heads so there is not a lot of room for this type of stop and being to lazy to make one I tend to use a toolmakers clamp like this:

A sticky pin is the same principal as a wobbler, it just gives you the ability to centre a pin in the chuck by using the centrafugal force. I never got on with them and find it unnecessary but I will dig one out later and take a photo to show how it works.

What I use is a 1mm diameter sewing needle and I grind the eye off it sits in the chuck nice and straight and once I have it aligned I spin it up and check for any wobble.

Turning to the edge of a thin disk, the bits of brass protect the jaws of the chuck and allow the whole disk to be turned

Being a poor pensioner I cant afford parallels and slip gauges but HSS tool steel is accurate. Also ball bearing the outer races are accurate and good for spacing work out from the lathe chuck

Here I am setting a slitting saw 1/8 inch below the surface

Never used a sticky pin, to locate a centre point. Always used a rigid pin/ needle.......

But, I spent a working lifetime, using one to locate the centre of components.

Stick it onto any hand rotatable spindle part........













And when you`ve done with it, for now.......




It sticks onto the machine, so it doesn`t get lost!

Great thread, maybe this should be a sticky so it can always be added to, good one Jim.
