The order for the production batch was placed several weeks back and they are currently in production. No delivery date was given but I will ask about progress on Monday.


Excellent :thumb

Just to let you all know.
The form tools have arrived. The price is £45 each, higher than the original quote but it is now double ended with a left or right hand cut and no front face cut, which were the points raised when using the prototype. Not tried them yet but will do so later this week. Be patient I have asked the webmaster to put in the online shop when he gets a chance.

Thanks Jeremy.

Now live in the Stores. Item code S4FT, which is under Misc products (scroll down the page and it is there).

Cheers,

When item is clicked and then “ please create an order” the form is empty.

I had that until I realised that I had to enter the number required in the box rather than just click on it. Then on to PayPal and done!

Hi Paul,

You just need to enter the number required in the box, it's not a tick-box. So just enter 1 and the order will be created - all the stores items work in that way.

[Edit] Thanks Philip for confirming this too :)

This is probably common knowledge, but with regards to re-profiling Romford wheels, it appears that 247 Developments are marketing a "Romford P4 axle plus nuts"

Along with much other useful stuff!

I plan to order mine after the Christmas rush given the usual problems with international post at this time of year. But that aside, has anyone taken their's for a test drive yet?

Cheers,

David

Had a little tinker with mine on some RTR Bachmann J72 wheelsets.

Bachmann have made the wheels with an non prototypical dish around the outside face of the circumference/rim, much like the recessed rear face of the wheel that they have nearly always manufactured. (For some reason Oxford Rail has also used a dished outer rim on their plastic/metal composite drivers on their J27).
Removing 0.7mm from the outside face of the Bachmann rim and 0.3mm from the rear allows the existing flange to be reduced with the form tool, whilst keeping it's position in relation the the outside wheel face correct.

Photograph probably explains it better.

In a way that looks more helpful to P4 modellers, since you now don't need to throw the RTR wheels away when converting.

Would we be able to have a step - by - step guide to setting up and using the tool for the benefit of us rookie lathe users?

I looked through this thread and found that the tool has a 6mm shank. But what was the final decision on material? Sort of assuming its HSS based on cost, but it would be good to confirm that.

Jeremy's post today on the thread entitled Tips and tricks in machine tool practice should help. There is a school of thought that this job may not be appropriate for the complete novice but of course one way to learn is to try. Using some scrap OO wheels, including wagon wheels is a good way to start before tacking the expensive loco wheels.

No special reason. High speed steel seemed to be the logical material to use. Fairly easy to obtain, although current supply difficulties did cause a delay. HSS can be sharpened if required although that is nor recommended since you may change the tool profile. The tool was produced using the wire erosion process which would no doubt work on other materials.

If really necessary an oilstone could be used on the top surface to remove any slight bluntness but if it is used as Jeremy describes in his thread for the final finishing profile sharpening should not be needed for a long time.

Shouldn’t be. As long as you’re not being overly aggressive with the feed rates. Bit of oil helps too.

Terry, I've also been thinking a stone on the flat side should help restore the edge. What grade/ grit would you suggest? My woodworking tools are usually sharpened in steps 1k - 6k -10k. Thoughts?

I agree with both comments. When making the final cut you are usually cutting across the whole with of the tool. This can cause vibration indicated by excessive noise known as "chatter" which can result in an uneven surface on the work piece. Some cutting oil, also sometimes called soluble oil is always useful when machining steel.

Yes an oilstone will certainly do that. I always use an oilstone to put a final edge on a lathe tool made from high steed steel or high carbon steel after grinding although it will not work on tungsten tipped tools. I have a very old ((55 years) carborundum oil stone for sharpening of woodworking tools which is of one grade only and that works for me. For lathe tools I have a very small fine carbourundum stone of the same vintage measuring 3 inches x 1 inch by 1/2 inch which I use for lathe tools. For this application I don't think different grades of sharpening stones are needed.
