How about the thompstone being serialized at the moment.

going to have a bash myself when I get the time. The last one Jason did (muncaster) was excellent enjoyed making that and learned lots of machining skills taboot.

Personally, I think this guy is a wind-up merchant who's extracting the urine. He has come up with objections for every sensible suggestion made by people on this forum. If he's that desperate and genuine about what he wants, he should design something himself. How about this?

If he replies, there's bound to be something wrong with it.

Looks like nobody’s much interested in the fact that they modelled the dynamic behaviour of nearly 20,000 individual rings.

Oh well sad

Thread: Jacobs Chuck run out
15/02/2021 19:15:59

Hi Geoff are you sure it is the chuck?

I had the same problem, turned out to be the stub was out that I had pressed it on to.

If you have the tackle try measuring it on a surface plate in a v block with a piece of silver steel in the jaws.

if you measure the silver steel with the arbor on the block and rotate it. see what you get.

then take the arbor off, put the silver steel in the v block and indicate the inside of the abour bore.

I found mine was cock on. I then rotated my 2mt spindle in the v block up against a stop with an indicator on the stub, and it was bloody miles out.

so you could try that it may or may not be that.

thats my own personal experience. good luck , let us know how you get on

Thread: testing stepper a motor
02/01/2021 20:34:44

Hi all

thank you for your reply's.

I' did test it and it was ok. re installed it and the gear train would turn with fingers (it wouldn't before).

Turned on the power and it did it's thing like they do and there was a bit of a clunk!!!!

same error code came up so I guess it is the sensor.

anyway To remove it I will have to take 3/4 of the printer in bits (I'm not going to do that)

I've spent all day on it and you have to draw the line somewhere.

So it's going on ebay, with the spare cartridges I have, as they are £100 a pop new.

thanks for all your help

regards

Hi all

I have a poorly printer and according to the manual the fault is a stepper motor or a sensor.

How do you go about testing a stepper motor? In idiots terms would be appreciated as I've no idea how to go about it.

I do have a multimeter

Pics of motor below

20210102_154033.jpg20210102_154108.jpg

It is from a HP laser printer and the part is (after a quick search) a bit thin on the ground in the UK, but there seems to be quite a lot about in the USA. Which could end up being quite expensive with the shipping.

Thanks in advance for all reply's

Thread: Delay to Issue 299
18/12/2020 12:52:36

Hurray, It's just dropped through letter box.

17/12/2020 12:34:05

Hi all

ME 4654 just dropped through the letter box, but still no sign of MEW 299.

are they supplied by the same shipping/printing company? seems a bit odd.

regards

Paul

15/12/2020 22:38:44

I still have not received my 299 of MEW issue either,

I have only just received my copy 4653 of ME today!

I'm only in yorkshire not in the back of beyond.

should I get intouch?

Thread: edge finder speed
06/12/2020 14:54:13

just out of curiosity what speed do you run your edge finder at and why.

I run mine at either 600 or 1000 rpm, seems to flick off better at 1000 rpm, it's a vertex made unit, and my mill is a warco super major, so only 6 speeds,

Reason I ask is I have noticed on youtube there are some videos that appear to run them slower than this and others much much faster.

Interested in your thoughts I,m NOT an engineer by the way, just a man with a shed that likes to playsmiley

Thread: stuart no 4 drawings
18/07/2020 07:03:35

Jason B

yes I know, but I didn't want to pay £14 + vat + postage just for the measurements for 3 components. I just thought somebody on here could help, If I have to then that's the route I may well have to go.

Hi all

I bought an old battered stuart no 4 a while ago that needs a lot of tlc, as a bit of a learning project. has anybody got the old imperial drawings that i could borrow/purchase as I need the correct dimensions of the con rod, eccentric & strap.(these seriously need remaking)

I have the drawings for the no 9 which I'm lead to believe are essentially the same engine albeit horizontal, so I'm assuming the rest crank, cylinder etc will be the same. but I don't think the con rod & the eccentric strap would be.

thank you

regards

Thread: hardinge 5c collets
04/07/2020 11:43:53

I've spent a couple of hours in the shed this morning faffing about and I removed the key. There was a small burr where the key protrudes into the cavity? I removed this with emery cloth, and tried the offending collets again, same results as before. although with 4 of them with a little bit of wiggling & waggleing I managed to get them in far enough for the screw to engage and pull the collet in. So it seems Pete Rimmer is right and my draw tube is tight.

On reflection of this, I'm coming to the conclusion it's not worth my while to mess about altering the chuck as all my other collets are fine. And I don't think altering the offending collets to suit would be something I could do. I may as well just buy some more imperial ones from arc or wherever, just for the very rare occasion I may use them.

plus my back stop won't fit as it's a different thread

Unless somebodies got an Ideaidea they are always welcome

thank you for all the replys

regards

Paul
