Thread: Stuart 'Victoria' : a beginners tale..
14/10/2013 09:29:12

Maybe it's like trying to ride a bike slowly (as in mountain biking). If you apply the brakes when pedalling it is easier to ride very slowly. It sounds odd, but it works. Although, that is more like putting a brake on the flywheel.

Thread: What did you do today? (2013)
13/10/2013 23:53:39

Had my first go at turning between centres for the S50 con rod. The surface finish is abysmal. This is the worst turning I've done since I got the lathe 18 months ago.

I made sure the tool was on centre height, and tried a right-hand knife tool, a left-hand knife tool (going the other way), and a threading tool which was probably too pointed. What is the correct tool shape when reducing a diameter between two larger ends? I've tried searching forums and couldn't find anything relevant. Do others just swap tools and try to minimise the join in the middle. Or is a round nosed tool better?

Oh and by the way, Jason, this thread is the best one on the forum and the one I always read. Thanks for thinking of it.

Hi Allan,

I've been following your build log from the beginning. It has a lot of similarities to the S50 I'm building although the Victoria is larger and more complex. You are dealing with many of the same problems I am, so the comments and suggestions are proving useful. Thanks for sharing it with us.

... I guess the reason is that the courser thread will be less likely to strip when tightening up the steam pipes/unions....

Eric

Thanks Eric. As Geoff suggested, that is probably the reason. I might ask Polly Models why they are much dearer but buy one from Reeves as they are half the price.

On a separate note, can anyone recommend a book that covers steam pipes and fittings. None of the books I've bought since starting model engineering seem to cover this area. K. N. Harris's book 'Model Boilers and Boilermaking' is on my shopping list for next week, so that might be the one to buy.

Thanks for the input, Geoff.

Beginner, like you Rick. I'd say my 6" flexible steel rule. One of the first things I bought and still use it all the time.

Thanks for the reply Norman, but as Jason has pointed out I've already got the taps and die, I was just curious why they had chosen that size. I'll probably buy one anyway at the Midlands show next week. I'm not sure my machining skills are up to making one at the moment but I might give it a go if I can figure out the dimensions or find a drawing of one.

Hi,

I'm gradually making a Stuart S50 engine. I've drilled and tapped the steam pipe inlet and exhaust ports 1/4" x 32 as stated on the drawings. I now find that most of the pipe unions available are threaded 1/4" x 40. If 1/4" x 32 unions are available then they are about double the price (in one example £8.40 for one). Does anyone know why this is the case and why Stuart chose to use a different thread than what appears to be the norm. I realise I should have checked first as then I could have drilled and tapped 1/4" x 40. Obviously I will just buy one but I'm curious why.

Thanks for any ideas.

Thread: New Look
02/10/2013 23:34:04

Just my two penn'orth but I think the new look is an improvement, much cleaner looking, easy to find what I want. Works well in Chrome on PC and Dolphin on Android tablet. Also, Katy is to be commended for her attitude in trying to sort out the complaints. Now, lets get back to the engineering.

Thread: The Best of Model Engineer Volume 3 Now available

I assume you mean the 11th, Keith. I think I'll give it until the end of the week before trying to chase it up. Might be that the despatch date is fictitious. Wouldn't surprise me.

Gary

21/09/2013 22:03:29

Same here Keith. Ordered 30th Aug, myhobbystore says despatched by Royal Mail on 11th Sept. Still not arrived on 21st Sept. So as myhobbystore are based in Kent and I'm in Manchester I reckon that even if the postman is delivering it on foot walking at 3mph for 8 hours a day it should still have arrived today. It brings a whole new meaning to snail mail. frown

Thread: Tool Height
17/09/2013 12:37:52

Hi David,

A QC toolpost was one of the first accessories I bought for my mini-lathe and has been one of the most useful. If you can get hold of any of the steel banding that is used to secure packing crates it can be cut up into small strips that are handy for packing up tool heights.

Well said Danny, I agree with your comments entirely. I've learnt a lot from Harold's books.

I'm sure these would make great (and safe) boilers for running stationary engines slowly, off load. Lots of steam at low pressure.

Neil

Does anyone think this would work? I'd love to see the little wobbler I made last year running on steam and haven't got round to making a boiler yet so might give it a try.

Thread: Basic equipment for starting milling ?
04/09/2013 23:27:23

Hi Ady,

I'm no expert as I've only had my mill for six months but two suggestions to start with are Harold Hall's books "The Milling Machine" and "Milling: A Complete Course" in the Workshop Practice Series. Full of useful info and starter projects including T-nuts, clamps etc.

If you just want to get started buy a 10mm HSS end mill and 10mm MT3 collet to take it. This won't cost you much and will get you making some swarf. You could also buy a clamp set which you will still use even when you've bought a vice and leave the vice purchase for a while.

Oh, and welcome to the forum.

Thread: May be worth watching?

Thanks for alerting us to that Jason. I hadn't seen it before despite watching more BBC4 than anything else. The swan and the boy writing were particularly impressive. If anyone wants to watch it then it is repeated at 2.20 am tonight.

Great. I've been checking for these on and off. Only annoying thing is, your 63T gear is now out of stock Neil. I hadn't even realised they were stocking them yet. Doh!
