Thread: Advice on Cluttered Dimensions in Drawings
21/03/2022 21:05:48
Posted by JasonB on 21/03/2022 16:20:55:

Dave as it's now clear it's for home use then no real need to worry about the latest BS standard or dimensioning styles just do it to suit the way you are going to machine it. It's only if you are going to make the drawing available to others you need to give it a bit more thought.

Although I do a 3D model of all my engines and check holes line up and moving parts like cranks and conrods won't hit anything when turning I seldom print off drawings for use in the workshop to actually make the thing from. Typical 3D of the one I'm currently working on. I just take off what sizes I need from the 3D part and get on with making it

I hope this won't make anyone choke on theirbeer but this is what it's built from, I think there is even an envelope or two in there and just one printed drawing.blush

But it seems to work for me as yesterdays little video shows. If it's going in the mag or for work then I'll approach things a bit differently

Would be nice to see this in the mag

That's correct, with it being cast iron it will take quite some heat and time to get it to temp.

Where as I don't think my EF would cut the mustard.

Just out of curiosity I went on CUP's site and notice they have a flux for bronze!

Jason, Bugger me I've got EF flux! so that wont do, JB it is

Geoff, thanks for that, a picture is worth a thousand words as they say.

Thinking about it I will try Jason's suggestion, use a smaller end mill and file the corners.

Now back to the shed with coffee in handsmiley

thank you all

Thank you Jason, I think I will have a go at soldering some cast iron first.

Then maybe it will make up my mind!

Hiya Nigel

I know what you mean, but this cylinder isn't as straight forward as that, The valve flange and the steam passages are in one "T" piece soldered to the side of the cylinder there is a picture of Jasons cylinder halfway down the previous page, or the drawings are in ME vol 226 no 4662 page 491 if you are interested.

I Think the only way round it would be rather than milling a slot into the cylinder, to mill a 10mm flat on the cylinder, that way I could machine the cylinder, flanges & decorative bands.

soldering it could be a problem for me though!

or part with some cash.

thoughts anyone?

26/02/2022 21:34:21

How does Jb weld fair with steam?

I do intend only to run on air but you never know.

methinks it could be tricky machining the slot for the valve and exhaust blocks with the flanges on.

mmm.

26/02/2022 18:58:54

Hiya Jason

Just made a start on this engine at last!

how difficult is it to silver solder cast iron if I used that for the cylinders?

bearing in mind i'm a novice.

thank you for your response in advance

Hi all

Only time I log in is when I want to make a post or offer my opinion/service in anyway, also when I need help or advice. (I'm probably what is termed as a lurker.)

I have found though, when I have made a post, or if someone messages me, the system does email me, so I do know to logon and reply.

Thread: Anyone intersted?
27/05/2021 20:23:55

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

I am, Just been working for a change, (need to earn some pennies). So I have not been logged on for awhile

You always seem to come up with interesting stuff, keep it up. Off In my shed now

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

regards

Paul

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

Paul

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

regards

Paul

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?
