Welcome Ian and congratulations on being given a lathe, that's a good start!. Please ask your questions here and we'll endeavor to help.

It's also worth typing in the keywords of any query, into the search box at the top. If there is something there at least it means that you don't have to wait for an answer.


Thread: Casting Thicknesses
18/08/2018 16:48:54

Those casting look very good Jason. Many thanks for your time on this.

I've managed to do a rough drawing of my project which is a hind wheel for a Fowell-Box patent traction engine (when I finish my Burrell-Boydell).

I made one of these some years ago and still have all my hand done drawings but I want to make this new one in 1 1/2 inch scale.

Many thanks for the replies.

Jason, I'll sort out a drawing and send it to you, your comments and help are very much appreciated.

At some time I will need to make a pattern for C.I castings. Now I realise that my question is a 'how long is a piece of string' type but I'm wondering if it will be possible.

The casting is 9" inches dia with 8 off webs around a 1 1/4" dia centre.

The webs need to be 3/16" thick. Will that work or do I need to look at fabrication?


Thread: What did you do Today 2018
17/08/2018 14:19:05

Finally gave up on Fusion 360. I've never gotten the hang of it. Instead, I've gone back to DesignCad but coughed up the necessary to get the latest version.

I've checked on a free trial version and it will read all the drawings I've done to date in 2D but with the added advantage that it will also do 3D. I've had a dabble at 3D with my old program but didn't consider it worth persevereing with but with 3D printing and machining it may be worth doing.

I'm just waiting to receive the authorisation code.

DesignCad produces outputs that are compatible with Autocad, which might be useful in the future.

Silver soldering looks good to me.


Thread: Are Model Engineering Exhibitions The Same

I must admit that I agree entirely with the previous comments about rucksacks, B.O. and shirtless men ugh!


Thread: More Fantastic Service
13/08/2018 12:49:16

I like to give praise where it's due, just as I will complain if the service is poor.

I ordered a die from The Tap & Die Company but soon after found the die I had been looking for, put away in the wrong drawer!

That convinced me that I needed a wooden box to store them in rather than the old tobacco tin that I had been using. I know that T&D sold them as I've dealt with them before so I 'phoned to cancel the die and order an empty box but could get no answer late in the afternoon so , more in hope, left a message.

I was very surprised to get an email from them confirming the cancellation and new order and the box arrived the day after, excellent service!


Thread: Hello

Hello Tim and welcome. If you have any questions, ask away, there's bound to be someone on here with the answer, sometimes even the correct one!.


Thread: Boiler feedwater connections
11/08/2018 07:46:47

I'm interested in the internal sizes of these connections and am seeking opinions.

Does the velocity of feedwater have an influence? Using smaller internal diameters for fittings should make the water travel faster. Is this useful in overcoming the resistance caused by boiler pressure?


Thread: Dimensions for Ball bearing Valves
10/08/2018 13:32:50

Brilliant Richard, that's exactly what I was after.


10/08/2018 10:13:39

Is the a formula for the size of hole to ball bearing size on these valves?


Thread: Hello from St Ives Cambs
09/08/2018 15:30:32

Hello Simon and welcome. I have fond memories of St. Ives and local villages whilst reserching my Fowell-Box traction engine model.

Any questions, just ask and someone will reply with the answer.

Blimey, the the Bugatti Chiron is probably the ugliest dog's breakfast of a car I've ever seen. Makes the Allegro look elegant!

Sorry if I've hurt the feelings of any billionaires out there...


Neil, I'm not a billionare but I agree with you; Etore would be turning in his grave.


Thread: Engine plans

Quoting rubbish like;

  • 437½ grains in an ounce
  • 16 ounces to the pound
  • 14 pounds in 1 stone
  • 7.142857 stones in 1 hundredweight
  • 20 hundredweights in 1 ton

is to use misleading information to try to make a point.

If it's belt driven it could be that the belts are slipping.


Thread: Hello from Dorsten

Hello Manfred and welcome to the forum. If you have any questions there is sure to be someone on here with the answer.

Hello Tony, have you tried ' Lathes' ? it's not just about lathes.


Thread: Inverter Drives for Motors
03/08/2018 17:35:40

My advice would be to buy from a reputable source.

I recently bought one to power a dual voltage engraving machine and the supplier, Direct Drives couldn't have been more helpful in explaining all the ins & outs. Their webpage has a lot of information but when I got stuck, they quickly sorted out the details I needed and the inverter has worked perfectly since.

I should add that I have no connection with them other than as a satisfied customer.
