It's hard to test a cap with a digital meter, the discharge kick is often too fast to operate the display.

I checked mine with an old school General Electric moving coil clamp meter. I have two 1/2hp motors one on the mill and one on the lathe (which should have a 3/4hp) both run at about the plated 4A current on idle or working, start up is 6A on the mill and 13A (big chuck to move and not a cap start either). The compressor is 2HP with 20A start and 11.5A run and plated at 15.5A. In the case of the lathe and mill off load means no belt on the motor pulley.

So for some reason the little ones do not use less off load.

It's always worth checking the motor current off load, this will show up a bad winding that is not running hot enough show on a visual winding inspection.

Milling carbide is a different grade, if you read the spec sheets some lathe cutters are suitable for interrupted cuts. Most have no mentioned of interrupted cuts, these are the ones that flake after a while, there a photo of a lathe tip after use in a mill - it's not pretty

In some ways it's a fairly simple choice you have limited space and a limited price + a limited weight.

Most large bench lathes are in the 300lb bracket so second hand is fine IF you can transport the weight or can phone a friend for help. 99% of commercial machines weigh in at double that weight and longer than the space you have. Lathes .co has the figures.

New machines are delivered so the weight issue goes and so cost and size are your limits.

Simply make a short list of those that fit under the limits and go and consult Google for all the moans (people love to moan) Pick the one with either the least moans or the one that don't concern you

Simples

That colour was known as Straw, anyone who worked on telephones in the 60s / 70/s would have seen equipment racks painted in it.

Turkish barbers, apparently men with beards are no longer able to trim their own growth so where we once had 2 barbers we now have 4.

Everyones a critic.

I think we have to remember that this video in really about showing these tools actually do cut metal rather than how to use the lathe properly, hence the lack of a finish cut + he's hand feeding so ridges are no surprise. I confess I did flinch a bit to hear the poor lathe slow down so much

On the link did anyone notice the downwards deflection of the second drill on the initial bite?

Would that be the drill ground off centre?

I think the fact that Bob Stevenson saw the video, saw the removal / feed rate and ignored the other issues, bought them to try and found he could make clocks with them shows the versatility of the tips given carbides reputation of needing monster feeds and speeds to work properly should be applauded. I'm certain the finishes that he gets on his clock parts is indeed mirror, else he would need to power his clocks with a 1/2 hp motor and not a main spring.

That answer has to be yes (but what hobby?   Most people do not want machines that require lifting gear to move, nor spend thousands on something

The Kennedy 60 or 90 hacksaw has a very simple open system that works.

He didn't then

Wasn't the barbed hollow belting also sold as emergency fan belts back in the last century?

I used some of the poly melt joining stuff for an IC model boat starter belt, it never broke despite the miss treatment I gave it. 15 years later it was rotted by the fuel

You have to remember that railway model engineers need a club for the cost / space / manpower for the different gauges required to run them. I'm sure that shunting up and down a 30foot track in their back gardens has limited appeal. Also Station Rd Steam has been banging out engines for those who 'want it now' for some time, where do these purchasers of model engineering fit in? It's not like the split between builders and drivers is a new thing, it just that the drivers have found a new & additional supply of ready built engines and the machine suppliers do not know they exist.

Those of us building TE's don't need a club except for the boiler certs, clock makers don't need clubs at all, neither do the builders of IC engines so it's not so surprising that clubs tend to focus on rail.

That's what wheel nut spider wrenches are for

Oh, and a big heavy rubber hammer for persuading modern alloys off the hub

Very true there is no such thread as AF, however old open-end and ring spanner sets can be BSF or Whit, I use them on plumbing jobs.

Imperial AF sockets will fit anything that matches the dimension 'across the flats' just like metric AF ones do.

Never seen a BSF socket set and I don't see the sense of having a set of spanners that require you to know the size of the threaded portion that you can't see especially when bolt head sizes are not standardised anyway. It's just a trial fit then use it so mixed sets are fine especially when the heads have been reduced by rust.

If you can find a Kamasa set you will be fine, they take a fair beating without using gas pipe extensions or a lump hammer on the socket handle. I got my first set from Greenshield stamps, the sockets are still good.

Make a soft alu or annealed copper washer either should stop it.

It seems a little OTT when almost every per 60's house in Britain has an average of 10M of lead pipe feeding the drinking water

Either leave it and deal with the resulting paranoia or stick weld it with very high nickel content rods, or spend more than the machine is worth having a pro weld it.
