Just type it in and look it up on Google Jim ... ;c)
Okay, seriously now .... Pretty much like I said in my write-up, I'm definitely still learning with this system, but my impressions thus far are that there is a lot you can do with it without having to change tool bits or set-ups, and it definitely is the easiest and quickest to resharpen, yet seemingly doesn't need to be redressed nearly as often. Haven't tried cutting threads with it yet, but there is a way explained in the instruction sheets. I'm not about to throw in my traditional shaped bits, but I do find myself using Eccentrics system more and more. One thing it most certainly does is give a much greater vertical load support to the cutting edge, than does traditional horizontally held cutting tools.
Hope this helps.
Must have been about to pull the trigger on one of these at least 20 times over the years Daniel.

How do you find the diamond tool bit Daniel?

I have recently completed an upgrade on my lathe that has added a digital read-out (DRO) to the carriage travel along the length of the ways, which had no other form of indexing available originally. It was quite a complex little addition actually, so I thought I might share a photo or three here. Actually, there was absolutely no modification to the stock lathe itself, as I made the entire assembly for the DRO system as an add-on via clamps, so there were not even any holes drilled and tapped into any part of the original machine. There was a minor problem in that the lathe offers an 18" bed, but the DRO scale that I was able to affordably obtain only offered 12" of travel, so I had to make the housing for it be slide adjustable so that it could cover the full length of the useable carriage travel. Of course 99% of all work seems to get done in the first 12" anyway, but there will always be some project wanting the full length of the bed, so that is now a possibility as well.

In the time I have had this little beauty, I have also added many other attachments, tooling and associated equipage, such that I'm sure I have far exceeded the original purchase price, though I doubt I've added even 50% to the potential resale value. But that is of no concern to me, as I have no intention of selling it, or if I get sooooo old as to eventually get around to that, I'll likely not be any too concerned as to what it sells for, just that it goes to the "right" person!
Among those items added that come readily to mind include a quick change tool post and several tool holders, a large assortment of various kinds of cutters, both new and used and HSS and Carbide, a set of the "Diamond" tool holders from Eccentric Engineering, that hold cutting tools at an extremely odd angle so that simple square cutting bits do most all jobs rather well. I'm still learning on this system, but it does offer many advantages in many but not all situations. Change tools a lot less anyway. I also have a set-up that should allow me to make taper cuts over long distances of perhaps 8-12 inches, once I modify it a bit more. The lathe now has two steady rests, two tail stocks, a spare carriage, a Jacobs chuck specific to the spindle threads, and keyless tailstock chuck with the correct taper, some spare live and dead centers of slightly different forms, and a host of other spare parts including gibb screws, banjo gear racks, some of the pulleys, gears, bearings, bushings and mount blocks for same, and a bunch of stuff that slips my mind just now.
One thing that doesn't slip my mind is the ER 25 collet holder, ala Dean Williams, that I made for mounting on the spindle nose threads. I did modify Dean's plans a bit to come up with a slightly shorter unit, but now see how I could shorten it by yet another quarter inch or so, though I'm not currently inspired enough by that as a gain to make another, it could happen somewhere down the road ... if I were to run out of projects ..... like that will ever happen?!?!

Note, I did not make the nut nor the collets themselves, but just the spindle nose mount chuck for them.

My lathe carriage stop is made from a micrometer missing the thimble ($.25 at a yard sale). It's as accurate as it needs to be for its job.
Some day, I'll replace that screw with a bolt having the same head as my tool post bolt; then I'll just need the one wrench.

Simple Die Storage
Pine boards, drilled with 1" Forstner bit to the right depth for the dies, two hinges on the back a clasp on the front and another pine board for the lid. Easy to spray with oil -

Thanks for the photos and video Frazer.

Although the travelling steady is handy its a right pain in the backside at time or at least I find it difficult to set up when making smaller parts
Around a year ago I was involved in the restoration of an automaton that require nearly ten feet of bronze at 0.078 dia and no way could I get the traditional fixed steady to produce that amount
Looking around I cam on a picture of a button steady and made one to fit my machine, The inserted button is made for the dia of the bar and the cutting tool is set to cut to the dia needed
Worked pretty well for a lash up and has got me out of jail a few times now
A very rough vid of it in use

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 LIKE THE DREMEL LOCK IDEA, I HAVE YET TO CONVERT OVER BUT AM CONSIDERING IT IN THE FUTURE, GOOD IDEA.

Thanks Carl, hopefully the thread grows.

Some great ideas that make the lathe a better tool.

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 -

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.

The Lathe, Mill & General Tool Talk Thread
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. Eventually 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
