Well everyday is a school day, I would have guessed Trini Lopez for that one but I see Pete Seeger wrote it in 1949, somewhat before the Trini Lopez hit in the 60’s

I doubt that any machine in the home workshop will have a motor large enough to be wound for 415v in Delta but large motors probably in excess of 7.5hp could well be wound for 415v in delta and 690v in star. A motor large enough to to benefit from star-delta starting will be wound for 415v in delta. At work we used some hoist motors that were on the cusp of being wound for being 415v or 230v in delta, as we ran them on a VFD then it was important to check the motor plate and set the VFD to match. These days it is likely that a small motor will be wound for 415v in star but it is not a certainty.

I lost my motorcycle keys at work, phoned wife to bring spare keys, found keys in pocket that I never use. Another occasion lost keys again, wife had a housefull of kids so could not leave, I said I would start walking and would meet when she was free, I had walked 5 miles plus and turned down a lift before we finally caught up with each other.

I am not quite clear as to what the issue is that you are describing but a DRO should be attached so it measures the actual quill movement and unless their is a serious problem with the spindle bearings it should represent the cutter position. If the mill is a knee type mill then it is possible to have a scale measuring the knee movement and a scale measuring the quill movement, a summing module can be used to give the true position of the cutter in Z whether you move the quill or the knee. The same method applies even if the table is fixed and Z movement is effected by moving the head or the quill. I think most people will lock the quill for normal milling operations for maximising rigidity. For drilling it can be simpler to use the quill or boring work with the head at an angle will mean using the quill.

This thread covered much ground with regard to the perfect rule, it may be worth looking at the suppliers mentioned in the thread.

Mike

As you mention a requirement that you will use as a cutting straight edge I would seriously consider a proper cutting rule, I had probably used a standard rule hundreds of times as a cutting guide until the day came that I had a couple of rashers of my finger tips on my cutting blade rather than on my fingers, no great harm done but it bled well and was sore for a couple of days.

workshop heaven have these but 300mm is out of stock.

The first electricians shack I worked in as an apprentice overlooked the lorry’s waiting to be unloaded into the press shop steel stores, one of the electricians had a Tufnol tube blowpipe and the production floor had a ready supply of mastic materials for ammunition, the drivers sat in their cabs waiting to be unloaded made an irresistible target.

Mike

Tallow was the regular cutting lube for steel conduit when I did a spell on the wiring gang as an apprentice. Trefolex is my favourite and I probably have enough for a good few years supply.

I am rather surprised that people have had bad experience with Dormer drills, I have various sets of Dormer drills and hundreds of loose ones and really can’t remember a dud among all of them. Being a top brand they will be first in line for the fake brigade to copy. Hopefully major suppliers will source them from the proper sources and should be the genuine item.

Nothing removed by me.

Our local man is obviously a good guy, my neighbour has asked Hermes to leave parcels obscured by a shrub but if it is raining or half term when the kids are around he knocks to ask me if I mind accepting the parcel for them, I am happy to do so and my neighbours reciprocate on the odd occasion when they are in and I am out. It works well for us but some friends accepted a bicycle for their neighbour who turned out to be away for two weeks so they were stuck with a bicycle and nowhere to store it.

The brackets on the tender were the same orientation, perhaps the different rail companies had different systems, from the bit I read about the lamp code it was not a universal standard. I suppose it would have been standardised after nationalisation. I am only a lightweight steam fan I know very little but find much of interest.

Mike

Yesterday we were on a shopping trip to the Swindon Outlet complex in the old rail works, the Steam museum is next door and well worth a visit but this Loco is in the shopping centre. As shopping is one of my pet hates I amused myself by examining the old machinery that is dotted round the centre. While looking at Ditchead Manor I noticed the three brackets on the black deck area and a similar arrangement on the rear of the tender, I expect everyone knows they are lamp brackets but it didn’t occur to me so a quick Google soon found the brackets with lamps installed, a bit more digging and I discovered that the lamps are installed in different patterns depending on the loco function. Everyday is a school day.

Well I did a speed read of the thread and missed that one, as an apprentice electrician it was often brought up that lightbulbs are lamps. I hold my hand up as one of the lamp lightbulb pedants but only for the fun value.

I just purchased some dessert spoons from Viners, the box had a big label that declared bladed item and check age of recipient. I knew one chap who kept his tea spoon in his breast pocket of his boiler suit, a six inch rule seemed to be good enough for many.

I assume we are actually discussing the changing of a lamp

All the teachers at my school were degree men from the best universities except for our metalwork teacher whose entry in the school list was simply his name. He was an inspirational teacher and was probably alone in actually having worked outside of the education system. At tech we had a lecturer who had worked in industry and then taken a post as lecturer at the tech college, he was far and away one of the most interesting teachers of electronics I have encountered as relating what you are learning to the real world gives the knowledge you are trying to absorb a purpose. I always found it amazing when something I had learned cropped up in a real job and sometimes in the most unexpected places, the saturable reactor turning up in a tig welder was a surprise and it took a while for the penny to drop as the sketchy drawing and pamphlet that was the manual did not remotely describe the machine. Much of what I have learned has eventually been useful but some of it just never has, I am not dead yet so there is still time.

Mike

I would remount the scale so that gravity is on my side rather than working against me, a stray chip could destroy the scale as they are usually glass and once broken or even damaged it will be game over. When I was a sparky in a tool room you had to wonder how swarf got to the places it finds, but almost nowhere was safe.

There are some very lightly used and carefully kept bargains on eBay of the big named makers and this is where I have purchased most of my collection. I have over the years bought digital versions in addition but I do overall prefer the purely mechanical version. Dasqua look to be quite nicely made but a picture doesn’t tell the whole story. I think I would test the water and buy one and see what it’s like before committing to a selection. The prices are pretty reasonable if you have to put the purchase down to experience.
