BDMS = bright drawn mild steel, clues in the name, black bar is rolled hence the scale rolled into the surface.

Totally agree with you Tony, most places I have worked the inspection departments were made up of failed machinists, those that were too slow or made too much scrap, and they strutted around in their pure white coats telling the “ handle turners” how it should be done, and getting paid a fortune for shuffling a few bits of paper. A case of Those who can, do. Those who can’t, inspect. I shall now collect tin hat and go hide in shelter.

Roy I have just dug out my Clarkson book, are you referring disk wheel and cup wheel part numbers 92612 and 92613, if you are they are just Clarkson reference numbers and will mean nothing to anyone outside the factory.. in the back of the book, page 27 in my copy are the British standard wheel symbols, these are what you need to use when specifying a wheel. Luckily on page 26 they list the full spec for wheels they used, cup wheel 38A150L8VBE, if they were good enough for Clarkson they will do the job.

All those wheels should still be available, they are all standard shapes, maybe not in those particular grades. It all depends on what you want to sharpen but a couple of four inch cup wheels will do most things ally oxide for HSS or green grit for tungsten carbide tools. Wheels can got from any tool merchant, can’t be more precise because we cannot mention names on here but an internet search will provide many sellers.

Pictures would be helpful.

I certainly wouldn’t want to take mine apart, get a bloke with a crane and lift it over the garage, they’re not very heavy.

Jason can you tell me where you got your lovely internal grooving tool from?

I am slowly building one, it’s about number ten in the priority list, getting locos ready for this season is top priority, but I would certainly recommend facing both sides and cleaning up the outer edges before cutting in half. The casting will never be to drawing, it was underside when cast same as the bar stock, mine is all cut dead length or slightly short, I have purchased a fair few Hemmingway kits over the years and the raw material in all of them is short to start with, I put it down to the fact that I live in the south and perhaps our inches are a bit longer than inches north of the M4 motorway. One thing I shall certainly do with my fixed steady is to make some decent adjustment screws, the bit of M6 studding I got in my kit is absolutely disgusting. I shall screwcut some 1/4 dia stainless 26 or 32 tpi, haven’t decided which yet.

Phil, he most probably got quickly promoted to foreman, at least that’s what happened to all the merchant bankers that I worked with, the more hopeless they were the higher they got.

Not come across any for a long time, I am still working my way through a ten pound tin that must be coming up 40 years old, still seems to be ok, needs a bit of a stir up before use though. I inherited it half used from my old man, will certainly see me out, must bequeath it to someone when I croak.

My biggest workshop mistake was ever entering one in the first place, got talked in to it and by the time I realised it was not what I wanted it was too late, stuck turning handles for a lifetime.

I looked at that model quite a few years ago and wasn’t wonderfully impressed, ended up buying a Emco PC50 mill with Siemens 820 control.

Nice windmill, can’t make out what the sign on the gate says. Is it open to the public?

Totally agree with you Paul but you have to remember that it is cold in the workshop at the moment and all the members are sat in front of the fire with nothing better to do. Model engineering is imperial because 99% of drawings are done in imperial, we all bought mics verniers etc years ago when they were imperial, we pick up tat from boot sales etc that is mostly imperial, we buy ex industrial machines, old Colchester Bantams and Bridgeport’s that were imperial. I was working up to ten years ago in the aerospace industry, all our drawings were imperial, all our measuring gear was imperial, the fifty year old Hardinge lathes that we were expected to hold half thou tolerances on were imperial, half of this country is still imperial.

I think we are missing something.......content.

Agree with Emgee it’s a bore or groove comparator.

Pete if is me you are referring to I will pm you loads of pics of what I have done.

Dave Wootton totally agree with everything you said, couldn’t have put it better myself.

One place I worked had a couple of Myfords used for making floats for flowmeters and another company used a Myford for machining cordite.

If it makes oiling easier I would do it. Boxford obviously thought it was necessary. At the end of the day it’s your machine and you can do what you want with it.
