Clive Hartland your comments are racist. This is not the place for such remarks. Nowhere is.

If you put vinegar on magnesium it will fizz! In fifteen years of melting scrap I have never had a magnesium fire.

Aluminium wheels provide good quality material. Gearboxes and other car related parts are also good. Just don't go for parts of speciality engines, avoid magnesium"

Howard, that is how I managed to do it in the Past, there must be a simpler method.

Boxford produced a book- "Know Your Lathe" It is available from Amazon (rather pricey) or free on line.

This is a problem that I have had before and it has taken a lot of fiddling around to get it right but I am not sure how I have done it. I have a photo in the memory in my computer and when I try to insert it into an album it flips through 90 degrees. What do I have to do to get it right?

I used to have the same problem but for the last several months I stay logged in for over a week at a time. I am not aware of having changed anything.

But you have to buy the speed brace, most people would have a bit of round bar in stock.

Howard, thanks for your suggestion. I had planned to have the tailstock end towards the wall. As I said earlier I don't have any round bar, to use as rollers, of a suitable size and to buy some would be a waste as I have little call for it, plus the cost of a pinch bar that would probably never get used again. If I had the headstock against the wall I could cut a hole in the wall to pass long stock through, with a flap to keep the draughts out. All my stock isl less than 600mm so whip wont be a problem, I made that mistake once and it is not something that I wish to repeat. I will be buying a ratchet strap as suggested by Michael, I can see further uses for that.

Thread: Chuck keys

I often have to change my chuck jaws to accommodate different sized and shaped jobs.I find it extremely tedious winding a jaw out to reverse it (4 jaw) or exchanging for inside/outside (3 jaw). I even have two of each chucks with the jaws set differently but I still end up having to change the jaws. I have seen the idea of making a carpenters brace type of tool to speed things up but it has never appealed to me as it seems to be a lot of work to make a simple tool. This is my solution, sorry if it has been invented before but I have never seen it. As I have multiple chucks the chuck keys are different sizes, so I took a piece of 12mm diameter bar and spent ten minutes to file it square at each end. Now I can use it in my cordless drill, what a difference it makes! What used to be a pain in the neck is now no problem at all.26925140-f9ae-4d35-9c56-85d5aea4e4dd.jpeg

The box and the floor are 20mm osb. The box has 3x2 corner posts and the floor is fully supported so I am confident it would be strong enough. Ratchet strap sounds a good idea, I could screw the anchor point(s) directly into the floor wherever needed, and a ratchet strap would have other uses, a pinch bar would unlikely to be needed again. Thanks for the suggestions.

a91c34d1-0b3b-482d-81c4-e28abd26fac8.jpegMy Loughborough is on a wooden floor but it is standing on a wooden box to raise it to a sensible height. It is not fixed down but I am not able to move it with my strength. I like the idea of a pinch bar. I had been thinking of complicated ideas like jacking it up and inserting rollers but I have neither jack or large enough steel for rollers.

What to do? I wish to move my loughborough training lathe through 90 degrees. I have tried but I cannot move it an inch. I don't have any friends to asksad, also I am impecunious. Any suggestions?

I can thoroughly recommend them. I have dealt with them for a number of years. Very quick service, good quality and if you need to phone them you will find them very helpful and knowledgeable.

Free cutting mild steel is the best, in my opinion. With brass you will have needle sharp bits of swarf showering over you and aluminium has a tendency to weld itself to the tip of the cutter.

If you just strop them on a piece of card you will get a little more life out of them.

I assume you are using a proper cutting mat?

Referring back to Ady1s comment about them being big speedboats with guns I was fortunate to have a tour of one in the Falkland Islands back in 2009. They did a demonstration run at full power and you could certainly feel the acceleration and the centrifugal force as they turned at high speed. So I would say that his description is accurate.

A few months ago one of my front incisors broke off as I was peeling a chestnut. I do not have any embarrassment when I am in public due to my mask. So no need for an expensive trip to the dentist.
