Thread: Copper for boiler construction
15/04/2019 09:52:16


I don't believe that you will have a problem if you go and speak to your local club inspector. You sound like you have done the best you can to control the materials etc. I suspect he will be more interested in the bush materials and the silver soldering stages. Also, please check your drawing. Many of the old drawings use threads in the plates for longitudinal stays instead of bushes. These features might catch you out.

If we start with material certification, we are heading for a minefield that you simply won't get out of e.g., most ME suppliers won't have proper QA, most self builders live at home, with a home workshop and no QA department?? Even if you had certificates, there is no guarantee that the parts are made from the same stuff. The QA issues go on and on and on and never end.

Thread: How to get that high end paint finish
13/04/2019 19:11:01


You are right of course i.e., use don't admire - but I repainted my lathe drip tray and cabinet about 8 years ago and it still looks immaculate. The odd scratch of course but it was well worth the effort. In my case, the lathe and cabinet had been stored in a cold damp garage from 1975 to when I took it. So the cabinet really did need attention.

I had to do the same to a Myford Super 7 drip tray and cabinet (minus the welding) because of age and rust.

The brushed red oxide primer instructions (oil based from Halfords) said that any paint could be applied over the top. So I tried some Halfords cellulose, grey spray primer. I had to apply several primer coats and use very fine wet and dry inbetween coats before the red oxide brush marks underneath 'blended in' to a reasonable level.

The final stage was to take a Myford belt guard to an automotive paint blenders for a match. They matched the gloss grey paint and gave me several large, rattle spray cans of the mixed paint (it wasn't too expensive at the time).

I have no idea what they did differently to the usual gloss spray paint that you buy but it was definitely cellulose and went on far better than any spray paint that I have used before. It gave a beautiful gloss finish and one large rattle can covered the entire cabinet and drip tray.

I now have plenty to do the lathe belt guards and tailstock if I ever need it.

Might that work for you instead of wrestling with the brushes.?

Thread: Drill too high? Use a milling machine stand!
10/04/2019 20:08:00

Nice plinth Alistair.

I had exactly the same issue but I went the other route i.e., I knocked one together from wood, plywood, plenty of screws and some spare MDF. It is now at a much safer height. The other major point for me was to bring the table and work piece low enough to get a good view of where the end of the drill is going.

I am now building another plinth to bring my milling machine table to a higher point!!

Thread: myford leadscrew

As T.B says, just disengage the gearbox using the selector arm and the leadscrew will rotate freely. The graduated handwheel is invaluable for measuring turned lengths. I use it all the time.

Thread: Chester 626 and Warco VMC spindle size
02/04/2019 13:31:18


I have just tried a No2 Morse tapered drill (with a tang) into the spindle of my Chester 16V milling machine and it won't fit. So I guess it has a similar spindle/ draw bar geometry to your larger, No3, 626 version.

Lovely engine, thanks for posting the link.

Thread: Round top inner firebox
05/03/2019 17:08:12


I am no expert but here are a few that I know of;

A flat top inner firebox will allow more tubes to be fitted. Apparently, the first third of the tubes length from the firebox is the most effective for transferring the heat, so the more tubes, the better the heat exchange.

The larger outer surface area of the square inner firebox will again allow more heat transfer to take place.

The disadvantage is that the flatter, squarer inner and outer firebox surfaces will need more support in the from of stays. So it could be seen as being slightly more difficult to build. Conversely, the curved surfaces of the round firebox are slightly easier to form and build.

Also, the outer firebox of the simple round topped boiler can obviously be formed using a straightforward length of tube - just cut and open out the sides.

The front firebox to barrel plate on a flat topped boiler is more difficult to form and build.

I am sure more experts will come and add or maybe even dispute what I have written but I think I have captured at least some of the pros and conns.

Thread: First loco

Hi Will,

Yes I think a slot that is .006" too wide does seem to be a bit slack but I am not familiar with the buffer beam assembly on Bat. I presume you are using a slitting saw on a mandrel? Thinner saws than 1/16" are available.

Thread: Gatwick Drone 'Attack'
21/12/2018 10:52:49

I am interested in the 'why' rather than a bit of disruption. We have had radio control planes and helicopters I the hands of teenagers for donkeys years with no known incidents of this nature - I don't think.

I think the question is why people would wish to bother causing this kind of disruption - along with damage to 999 vehicles. Why are people doing it?

Ill check my bill. We get the calls very frequently (not sure about the number though) and it usually goes to the answer phone. I assume I am not being charged for that - or am I?

Thread: Myford ML7, or Colchester Bantam/Boxford model A easiest to use?
05/12/2018 17:22:27
Posted by Brian H on 05/12/2018 15:39:24:

A friend of mine always says " you can do small work on a big lathe but you can't do big work on a small one".


Brian, that is obviously true but trying to make small engine parts (for example) on a large lathe becomes very uncomfortable. Also, doing operations like chuck changing etc are also less than convenient.

I had a Myford ML10 but now use a Super 7. I honestly miss the Ml10 - specially for small parts.

Men Ifr,

You haven't mentioned (unless I have missed it) what you are thinking of building with the lathe once you have it. As an apprentice, I used all three types of lathe and it really does matter what you are doing with them.

If they are all adjusted correctly, all of them can achieve a superb finish with a properly ground and set cutting tool and all of them can cut threads.

Again as an apprentice, I cut some rather complex threads as an exercise e.g., twin start, left handed square threads, pipe threads, very chunky acme threads etc. At home I use taps and dies. I can't remember the last time I cut a screw thread on a lathe.

The larger the lathe e.g., the Colchester, the less comfortable it is to machine very small parts. The smaller the lathe i.e., the ML7, the less comfortable it is removing huge chunks of metal off larger components.

I think what you are using it for is the key starting question.

Thread: Tool and Cutter Grinder
03/12/2018 22:30:33

Excellent point XD and another good point regarding Harold.

I think I will get sorted for the next exhibition that I go to - probably in Manchester. Ill either decide to make use of this small mountain of HSS steel, buy some cupped wheels and make some form of cutter grinder or sell the majority of the tool steel and buy a load of tungsten tips.

Phil H

It might have been an economics thing but in the toolroom - we always changed to a white wheel for HSS. It might have been a coincidence that the wheel was white and who knows what grit colour is around these days but that was the rule of thumb.

Oh, please don't take this as gospel because it was a very long time ago but I think we used a green grit for roughing the tungsten. It was great to remove material but left tiny chips on the cutting edge. the wheel was changed for diamond to get a keen, clean edge.

Phil H

03/12/2018 19:37:55


Yes you are correct. Diamond for tungsten and white for HSS.

03/12/2018 19:26:49

Les, Thanks. More food for thought.

03/12/2018 19:21:14

Neil, That is exactly the type of thing I was thinking about - thank you very much. Simple but effective - I like it.

Not done it yet; Perhaps I should have given a little bit more detail instead of being so vague. I think it is the 6", relatively small radii grinding wheel arrangement that is the issue. The motor still runs very nicely so I think that changing over to a proper cupped wheel as Neil has shown will work well. Can you see any issue with his suggestion?

Phil H

03/12/2018 17:36:07

I have a Machine Mart style 6" bench grinder which isn't particularly brilliant for grinding HSS tool bits. I am thinking of using it as a basis for a simple but effective tool and cutter grinder. Has anybody done such a conversion. I did try a search on here but didn't find anything along these lines

Thread: Britannia Tender kit from Model Engineers Laser
03/12/2018 12:43:55

Just a suggestion Rod,

Why not start by posting some pictures of the chassis showing where you have got up to and what your current challenges are. I'm sure you will get more constructive help from the forum. I'm guessing the chassis has fewer parts and is easier to show your snag list. If that works, move onto the body.

I can understand why Malcolm hasn't produced an Airfix style set of instructions because I guess it is time consuming and not very profitable (time versus return on that time). Perhaps you could help others by posting your progress and get help with your project at the same time.
