"Did a bit of shopping, didn't spend a lot as TBH not a lot to spend it on."

so you didn't see the set of moore and wright telescopic gauges for sale at £45 0n the first stand to the left of the entrance(HJH Tooling)

Ian

Damian. I'm sure you will very pleased with your machine. There's something very satisfying about cleaning the grime off & giving a quality machine a new coat of paint.

As for tooling I bought an ER 25 collet chuck & a set of imperial collets from CTC tools. ( there's other cheaper sellers on ebay)

I also recently bought a set of metric ER20 collets for a drill grinding jig I built & at the same time bought a ER20 collet chuck for the mill for when the size of the ER25 collet nut is to large.

My mill uses a No 2 morse taper in the spindle.

This is how the rotaing base is fabricated for the Bonelle T & C grinder

Ian

That's unbelievably fast

John.

Well done that's good news.

John.

The 5v connection is to output 5v to the stepper driver if required. It's NOT for 5v in.

The in voltage of 24 v connection are to the left of the PCB as viewed with the terminal blocks along the bottom, this is regulated/dropped to 5v for the 5v output as mentioned above, & microcontroller power ..

You say when you put 24v into the driver nothing happens do you mean the stepper motor driver or the Steve Ward controller?

Have you programmed the microcontroller?

Are you using the latest PCB as purchased from Steve.

Maybe a photo of your 's would be helpfull.

Jez.

eccentric engineering sell them :-**LINK**

This is their Australia site but I think they have a UK agent, they are also attending the Doncaster show this weekend.

Ian

Maybe these clamps from Arceurotrade are the answer:-

With the latest version of firmware (v2.21 I think) if you hold digit 2 pressed and turn on it configures the keypad

Extract from Steve's manual:_

"Keypad Orientation
Note that the keypad orientation can be automatically configured on first power up for
non-standard keypads.
To do this press and hold button [2] whilst powering the unit on and continue holding
the button until the message “Keypad Orientation” appears.
The button can now be released and the unit will store the orientation in non-volatile
memory for future use so there is no need to repeat this step.
The rest of the text under “Keypad Orientation” is for information only and will only
be displayed for a short time before normal operation commences."

Ed.

Steve Ward sells the PCB's for just £6 + p & p which I think is very reasonable for a professionally produced PCB with component values/number printed on it.

Ian

Looking on their WEB site this is stated : - "Please note all prices shown here appear to be different to our catalogue prices as all prices contained here contain VAT, prices in our catalog are all plus VAT."

Does this explain the confusion?

"so its hard to know if I'm just posting for the sake of it or if anyone is finding it useful"

Jason.

You are certainly not wasting your time. I've followed this thread from the start & have been down loading the plans. I intend to build this engine in the near future. I always find your post's interesting and informative..

Ian

I'm pretty sure when i have phoned them in the past and if it's there dinner time I got the answer phone.

Andy.

I believe they used to use lignum vitae wood as guides on bandsaws.

Very hard & self lubricating.

Here is a source :-http://www.turners-retreat.co.uk/timber/pen-blanks/5-8-blanks/lignum-vitae-5-8-x-5-8-x-5

Or crown green bowls are a good source as well, but you will need a bandsaw to cut it

So it's a valve grinder then.Thanks to every body for your suggestions.

Ian

Morning.

Spotted this partly buried in a local scrap yard.

I've searched the internet for information with no luck.

Any ideas?

Ian

Jason.

Looking forward to your next post.

This looks like a good build project for me ?
