Thread: Silver soldering boiler
27/05/2020 17:49:30

Yes, agree with Pete, looks great.

The smoke stack puzzled me but having looked at the drawings on steves website I can see that it is for the engine exhaust.

Have you made a burner


Thread: What Did You Do Today 2020
22/05/2020 19:24:37

20200522_120155.jpgToday I completed a long overdue upgrade on the m type20200522_104459.jpg

A new bronze cross slide nut fitted, supplied by David George, thanks again David.

The nut has been made very accurately and the feedscrew is a near perfect fit with just a tiny amount of backlash

Also took the opportunity to add mini thrust bearings front and rear of the bridge plate, similar to the ml7 improvement.

The whole job makes for an amazing improvement, feels like I have a new lathe


Thread: Gas Strut for Mill
21/05/2020 16:08:32

About a year ago I ordered a 6mm strut at £27 for my sx2p but it was out of stock.

I noticed that they have now reduced the price of the same strut by £6

Unfortunately it is still out of stock!!!!

Thread: Silver soldering boiler
15/05/2020 10:04:46

Hi David

Thanks again. Given the small size of your boiler I was thinking it may be possible to complete the annealing and soldering of a boiler that size with a canister type torch, which is what I have.

Apparently not, I'll give it some more thought as clearly I need equipment with a much greater heat output


14/05/2020 20:45:16

Hi David,

thanks for your reply.

I'll check out Steve's site.

I use M machine as well, good company and thanks for the material details.

What about your torch. Do you have one that attaches via pipes to a large propane gas bottle or have you managed to do all the annealing/soldering with a small gas canister torch?


14/05/2020 10:31:13

Hi David,

Very impressed, nice job.

I've been thinking about making a small boiler. I have 4 small engines and would love to see them run on steam.

I have a few questions.

Firstly, boiler material, what type/grade of copper and bronze have you used, also what gauge for the tube and the end plates and what grade of silver solder have you used.

Secondly, what type of torch have you used for your heat source for the annealing and silver soldering.

Finally a general question for anyone. Would this size of boiler be suitable for a small engine up to say stuart 10v size.

Cheers Geoff

Thread: Needle File Recommendations?
13/05/2020 17:24:48

Hi Hollowpoint,

If you want an inexpensive set of small needle files try the 6 piece blue spot mini file set on ebay.

At £3.89 for the set you have little to lose and a lot to gain.

I bought a set from Boyes in York nearly two years ago, I've used them a lot

They are cheap and cheerful but nevertheless great value for money.


Thread: Taper Pins
10/05/2020 17:04:25

Hi Chris,

Looking at your picture below the pin is clearly visible so would be easy enough to remove if necessary.

The later Myford builds had the pin machined flush with the center ball and after many years it became virtually impossible to locate the ends of the pin making removal a real headache.

Your Myford built lathe, 1944 is it, clearly has Drummond made parts which would probably be right at that time.

The handle looks like Drummond made one , a slighty different shape to the later Myford handles, although the handle knob remained the same throughout. The bridge plate is a Drummond, the later Myford plates were countersunk for the three cheese head screws.

HI Chris,

You have some good advice here, not a lot I can add.

I bought my taper reamers from Tracy tools, good company, never bought anything from them that I have been unhappy with.

I made some twenty tooth drummond gears many years ago. Drilled the pin holes the same size as smallest diameter and then reamed by hand for the pin. Very easy in cast iron.

From your first post in this thread you say you "admire" the taper pin method of securing the topslide handle on your M type. WHY?

Do you plan to remove the pin for any reason. If you are, good luck, they can be right b******* to get out. If and when the handle is off the machine do fit a topsllde index dial before replacing it, not difficult to make one, more details on request.


Thread: Another Engine Build
07/05/2020 11:59:03

Base looks good Ron

I need to make a similar shaped wood base for mine.

I like the undercut curve

I have a router bit with a guide roller bearing

Must give it a try, lots of time at the moment


Thread: Muncaster's Simple Entablature Engine

Crikey Ron you're up early but then so am I!!

Paul you can get them on ebay at sealsuppliesuk

They call them viton rings not vitron

I assume they are the same thing?


Thread: Drummond/Myford M Type
02/05/2020 11:21:42

Yes you're right Chris it's not original, I didn't read the listing.

Improvements, well the vee drive definitely, the stand and self contained countershaft, the bench countershaft.

They also prototyped a new apron which incorporated an extra gear to reverse the rotation of the saddle handwheel. I suspect that is all it was though, I have seen no evidence that it ever went into production. However I would love to be proved wrong on that point.

On the downside Myford did stop using the horn handles replacing them with their standard pattern steel ones, they cheapened the half nut arm with a more lightweight casting pattern and what I appeared to me was an inferior grade of cast bronze. They were no where near as durable as the drummond arm which was originally made from cast iron and later models from bronze. The drummond arms were much heavier and thus more substantial the later Myford ones were much more prone to wear and subsequent fracture damage.

Hi chris

Have a look on ebay, hand rest for sale

Looks like you have one of the very early myford built M's

These would have been made from parts supplied by drummond brothers in 1943.

The later post war lathes had the myford "improvements"

Post some pics in your photo file, let us have a look at it

Thread: eccentric strap
01/05/2020 11:00:26

Thank you Gents for your replies

Bore first it is which what I would have preferred to do.

I'll go and do it now!


01/05/2020 09:30:18

HI all

In the photo is a brass extrusion supplied by stuart models for the eccentric straps on a stuart 10v reversing gear mechanism


I am not making a stuart 10v engine but one of a similar size, non reversing and just using one half of the extrusion to make one strap 5mm wide 16 mm bore.

My intention is to machine the strap as per the stuart drawings which would involve slitting the strap for an adjustment screw.

Do I slit first, add the screw then bore or bore first then slit and add the screw.

My problem with the latter is the possibility the slot may open up or close after slitting, or I am I worrying over nothing?


Thread: inland seagulls
29/04/2020 17:23:54

Landfill sites? We have one about 3 miles away as the crow flies or in this case the gull.

Not seen them today, expect they've gone there.

Seems they are inland a lot more than I thought.

We are always keen to attract wildlife into the garden but them yesterday was like a Hitchcock movie

Ann and I have lived in our current house for nearly 30 years.

We are around 25 miles from the nearest coastal point at Crosby on Merseyside.

In all the time we have been here we have never seen seagulls in our back garden, until yesterday when a colony of them very aggressively made their presence known. Big b*****s strutting around like they owned the place.

I understand that inland seagulls is not unusual but I can't help but think this must have something to do with the current coronavirus crisis we all face. 25 mile inland seems a long way to me so these birds must be pretty desperate.

To add insult one, or more of them unloaded their bowels on my freshly leathered MR2. Unfortunately I didn't have a shotgun handy or I would blasted him all the way back to the coast.

Anyone else seen inland gulls recently


Thread: Drummond M type drive and parts query
25/04/2020 19:29:05

I'll have another look. I'm waiting on some new 1/8" balls for the thrust bearing..I only found 11 out of 16...

Hi diesel

You can buy a complete replacement thrust bearing from "simplybearings", fits perfect, stock number is FT 3/4.

Go to thrust bearings, search 3/4" bore and it will come up.

I would suggest that you go "V" drive with your headstock. Easy to do IF...... you can pick up a later drive pulley from a Myford built M type. Sadly easier said than done, but if you can get one it is a direct replacement for the Drummond cone flat belt drive pulleys.

Get a copy of Lawrence Spareys the Amateurs Lathe. There is a good chapter on setting up a lathe for motor drive. A good example is for a Drummond B type on a Drummond stand, same as your stand and a similar lathe. It's an easy set up which does not require specific engineering skills, easily built by a good mechanic.

Stick with it you have a great lathe, worth persevering.
