Slide-Rule !, an essential tool on the Airline Flight Decks and Load Planning Offices still in the early 70s. almost disappeared by mid 70s. I/we also mistrusted Electronic Calculator's answers when they first became available. Only used to check figures after manual calculations in 6 digits for quite a while. Also weren't allowed for Weight and Balance License Exams.

So today, I made a small dent in producing the some of the small constituents of my T. Engine's 'Outfit' by finishing the Axe and Coal/Ball Pein Hammer(s). They have 'Wedges' inserted as well-

Still too cold for me to spend much time on the machines in the Cave.

I suspect the words 'Fly Cutter' as stated in LC Mason's book refers to the 'Between Centres' type Boring Bar which Malcolm is looking for?. It will be for machining the Curved faces of the Chimney Saddle, Cylinder Block and Motion Plate, probably Gunmetal. with a max radius of 1.5/16" (33mm-ish).

When I carried out these jobs, I made a Between Centres Bar out of 1.3/8" dia BMS and a 1/4" dia HSS round bit. Exactly as shown in his book on page 96 (Fig 42). Slowest Back Gear speed and finest feed to start.

The Chuck/MT retained Fly Cutter types would probably be best suited to producing flat surfaces due to lack of reach/clearance. But then I am making assumptions here.

As my Father described to me, a Bevel to be a relieved edge of unequal angles i.e. 44 deg or less, say on the edge/corners of a Mirror.

A chamfer to me is an equally relieved flat edge of 2 joining faces of usually 90 degrees. i.e as on a single or double chamfered Nut

A Fillet is an edge that is relieved in a rounded form.

Nowadays, It's the only time I find wishing my life away by looking forward to the 27th Dec and the longer days ahead.

But I have to say the on two of my other Forums, they dress them up seasonally which gives a strange degree of satisfaction in 'Popping the Lights with the PC Arrow Cursor regularly after refreshing their Home Page!. Yeah, I'm SAD !.

TPTV is my default channel. So glad it came to Freeview. Been in touch with the Owners of it ( Family run) to express my thanks for the variety of Film content and the 'Glimpses' of the old Industries, Pastimes and places.

If I had to replace, or add to my 40-70 year old Sheffield Steel brands file stock, it would be the Sandvik (Coromant) Brand. You'll get what you pay for in quality and durability. A good set of assorted Swiss Riflers are also handy.

Maybe if the Screw Thread was invented in the Southern Hemisphere, it might have been L/H form.....same way as water goes down the Plug 'ole !.

I'm also a generic 'Leftie' like writing and most agile/strongest arm and hand, All over the place otherwise- Golf,Cricket, Chainsaw, Drill and eat with Knife R/Hnd'd , Handsaw, Shoot and use Screwdriver/Spanners with Left.

I steer clear of Black Powder Flintlock Muskets !!!!!.

Not sure why you need to remove and separate the Handle Boss from the Eccentric Shaft ?.

When I refurbished my Counter Shaft/Drive Ass'y, I removed the whole piece (part nbr 75/1613/1).

It is listed in Myfords Manual as an Assembly (1 piece unit). Only the Ball Handle unscrews.

Only requires the removal of the Shaft Collar/ Stop Peg at the opposite end of the shaft. Carefully filing any Burrs from the Eccentric recess edges and withdrawing, while supporting the Counter Shaft.

It can then be worked on without subjecting the Frame Ass'y to unnecessary forces and possible damage (Aluminium casting).

No we don't all play with them. We all have different side line interests. I mix the hobby with various machinery interests, but use the workshop equipment to restore them.

My neighbour friend restores early 70s Honda 750s though.

I also have a 'She who compromises and agrees'. We don't use the word obeyed.

Welcome to the Scrap Heap of life Robin. It's not really that bad though.....it's great for me.

Got my first pension last week so I'm officially an 'Old Git'. I retired 10 years ago from formal employment and been doing what I wanted and when since. Had to be frugal, but glad to be rid of the enormous stress, long hours and poor diet.

Took a while to get used to the slower pace (about 2 days .

Not worth the effort fighting change, might just as well adapt to it and cling on to what you personally want to keep. The good thing is you now have all the time in the world to adapt at your own pace.

Just enjoy it!.

If the Boring tools you have used are found not to be the cause, how well adjusted are the Gib Strips on the Carriage?. If there is too much slack there, it can produce the issues that you have. It may even be a combination of both !.

I use the old thread forms most of the time anyway, due to my habit of rescuing older machines and engines.

Talking of Myford T-Nut material (sold in 8 inch lengths initially), I remembered I had one I bought 30 years ago. Could it be a collector's item now ?

Variety of Fixing types,sizes and quantities are still available in UK. Some may be aware of them and I get most of what I need from Namricks. Usual disclaimer.

I'm Metric at one end of the Workshop and Inch standard at the other.

Forgive me if I should post this elsewhere, but failed an attempt in the Classifieds,or if it is acceptable (remove at your leisure)

I posted this here on behalf of my good friend based on a promise he made to a family friend.

This is an Ebay link to the item and the description explains all.-

vkAAOSwmVBZf5G5">Vintage WW2 Lathe

I would prefer this to reach the people who value these machines and I would buy this if I had the space for another project.

I hope it may be of interest to someone.

Thanks

They must have made it from what they believe to be Platinum originally (1791), as Iridium wasn't discovered until about 1803 I believe,.... by an Englishman?.

Also being of Luddite tendency, It won't bother me in the slightest either really.

Last few evenings I've been retrieving my (100s) images and replacing the links in my other Forum's Threads.

Fortunately, the Forums are up-to-date modern versions and allow 'Supporter Status' with no Ads and unlimited storage.. The Moderators gave me temporary 'Edit Status' to carry out the work.

I'm glad to be able to dump them, as I've grown tired of their grossly unresponsive Website for many years.

So you could say I was 'Pushed' to leave, but would have Jumped eventually.

Regards

Nice example of old quality Windy.

Engine Turning seems to add an appearance of quality to many items.

I also agree that it serves to preserve a surface better. I did some random E/turning on the Throttle Plate I made for an old Carburettor I rebuilt before 'Bluing' and quenching in Oil. Certainly renders it resistant to corrosion and looks nice....even though it is out of sight.

Regards

Thanks for the 'Heads Up' on this. I've put it on my Birthday list for July. I've followed F1 since about 1959 when on TV. Only been able to go to one race in my lifetime to date. Will be a great addition to my library. Thanks.

The bore was not true, as the Plug Gauge I made passed through smoothly for 1.1/8" and then became tighter. I wasn't happy to leave it that way, even though it was only a few tenths of a thou, and so with patience, the lapping removed it. Haven't got a pic of the bore/Lap etc, only this one of the end of the Cylinder with the Piston at full throw-

No reason why you can't do the same if you wish, despite having drilled the passages. All you'll need to do is to fully clean them out after.

Regards

Hello Brian, I had a similar dilemma with the bore, and unsure of the standard of finish necessary. I decided to polish it to size and finish by lapping anyway and before drilling any ports into it.

I made a brass lapping tool about 2" (50mm) in length and as true to 5/8" dia and parallel as poss with shallow grooves spaced 3/16" apart along the length to carry an abrasive (T-cut original) mixed with White Spirit.

It took me a few hours, but the results were excellent and allowed me to make the piston a real good smooth fit.
