Thread: Help with lathe operation would be much appeciated.

Where are you located Brian?


Thread: Mag scales and steel screws?
13/06/2020 12:02:54

I've not found a problem using my Machine DRO magnetic scales which are attached with steel fasteners. They are, after all, fixed to a rather large iron milling machine.

A "family shot" of progress so far on my version of Stew Hart's Dads & Lads mill engine.

The governor is a Bangood special .

There's still plenty to do; when I've got the eccentric and flywheel done I will look to getting the crankshaft drawn up so that I can fit a driving pulley that lines up with the governor.

Looking good so far.

Nice result Mark.

One of the joys of such an engine for a beginner project is that mistakes (we've all made a few I'm sure) can often be recovered with a little ingenuity. My own version also has an air inlet in the back of the frame.

Lovely runner again Jason and a lovely looker too.

I have used Mamod drive belts on a couple of governors and find that they are not very smooth running. I put it down to the fact that they are in effect long thin springs and so can react to varying loads from say bouncing balls or momentary tightening of the drive shaft by stretching and slipping rather than continuing to drive the governor. When I get a round tuitt I intend to try and find a different drive belt material.


Thread: Another 'glue' question
21/05/2020 20:21:09

Although it may well work, I don't think that Loctite is intended for this kind of application, more for shafts in bores.

I too keep a bottle of cyanoacrylate in the workshop for just this kind of job. I find that it will stick within a short space of time, especially if your fingers get in the equation with the parts you are fixing, but the bond is better if you can leave it for an hour or so. As with all adhesives cleanliness is a good thing. To unstick it moderate heat works well and to avoid distortion I find that dropping the glued assembly in hot water usually does the trick. In the case described in the OP's question I would heat the casting with a hot air gun until the flanges fell off.

Thread: Ron's Jowitt Popett Valve Engine
13/05/2020 16:06:14

Well done Ron. Coat of paint and a base and it's on to the next one.

I'm surprised we dont see more of these Jowitts, as you found they're a little bit out of the ordinary run of steam engine and with care produce a good looking result.

More of the Dads & Lads mill engine to show - the valve chest assembly.

Here's all the bits including the "enhancement" of an exhaust manifold to fit over the as designed plain outlet ports.

And here's the assembly complete with the Banggood governor on top.

Having completed the Muncaster Double Acting Oscillator I had no next project lined up. Looking at my collection of engines I saw that I did not have a horizontal mill engine other than trunk guide crosshead type. Soooo I thought that Stew Hart's Dad's and Lad's Mill engine would be a fairly straightforward job for me and I could add some of my own "enhancements" to it along the way.

I gathered together some materials from the come-in-handy bin:


and set to. First stop is the cylinder:

cylinder 2.jpg

cylinder 3.jpg

and already there a couple of enhancements, the cylinder base having visible mounting feet and the piston rod gland, and a upcock which is trickier to see. I have made the cylinder with the inlet ports on the wrong side. Putting the cylinder head on the other end would correct it but I'm not too sure about the concentricity of the piston rod to bore if I did that so it is staying as is.

That is indeed coming on nicely George. I have seen this engine in the past and not been too keen on it but yours will be a great looking model for sure.


Thread: The Home Workshop Dictionary - FREE E-BOOK
24/03/2020 19:21:43

I, too, failed to "read the question" and thought that Amazon were pulling a fast one and trying to get me to subscribe to Kindle Unlimited so I passed on the Dictionary.

However, while I was on I noticed that Amazon had the Norden engine book written by Neil and since I am slowly getting together the wherewithal to build one, I bought that book instead.

Now that I see that I had jumped the gun on the dictionary I'll get that tomorrow. Thanks Neil.

Jason thanks for fixing the link. I always have a battle getting them to work but I thought I had cracked it this time as it worked OK for me.

There now follow some still pictures and a vid of my finished Muncaster double acting oscillator:

My thanks to Geoff Walker 1 for generously gifting me some drawings and a cylinder casting for this engine. I hope I have done it justice.

At last I have finished Muncaster's double acting oscillator and when I figure out how to get my u-tube video linked I will post it and some pictures.

Thread: Silvers soldering
22/02/2020 23:10:04


I don't know how Jason removes Tippex, but I find that what I use easily comes off along with any burnt/dried flux residue in the pickle bath and after with a scrub with a toothbrush. (Don't let on to the better half whose toothbrush you use for this.)


22/02/2020 14:44:59

I use a coat of Snopake typing correction fluid where the solder is not to flow. (Note that this fluid will not correct machining errors!)


Thread: WM18 - Broken it again :(
18/02/2020 11:35:34

To answer the OP's question I can advise that 3 years ago I foolishly cooked my lathe motor in a similar way by cutting a large diameter bar of unknown, but tough, steel at too low a speed for too long. The resulting lack of cooling made the motor far too hot to touch even 15 minutes after it gave up the struggle. The cost of a replacement from the machine supplier was close to £150.00.


Thread: Ron's Jowitt Popett Valve Engine
17/02/2020 10:35:21

Hi Ron

As Jason says I built a Jowitt from his plans.

finished jowitt 7.jpg

You may see the resemblance. Being a bit careful with a penny, I made the flywheels rather than buy in a pair of castings. The wee brass pulley came from my come-in-handy drawer.
