I've always been fascinated by the things people do in their spare time when they can do exactly what they want to do. Men and sheds are a particularly fertile field. Women tend to do their thing in the comfort of the house.
I was delighted to see Andy's picture of the clock movement he has made.
It struck me that we could perhaps start a new topic devoted to spare time skill. So Andy starts it off and my contribution is this:
It's a small steam engine made from scratch and is based on the Stuart 5A but a longer stroke. One of these will drive a 14 foot boat with steam at 250psi. By the way, we don't like to call them models, it's exactly the same construction and materials as a full size engine, just smaller. So come on out there, let's hear about what you make in your spare time. I reckon we could be in for some surprises!

I don't know whether it was the sunshine but I got inspired today to do some major cleaning up in the kitchen and the workshop. I even found myself washing paintwork down! Must have had a funny turn, I think it's out of my system now..... One thing is certain, I have the cleanest workshop in Barlick!

Another gear blank emerging from a piece of scrap. This started off in about 1900 in Hopkinson's at Huddersfied as the front cover on one of their boiler feed valves. I've had to reduce the thickness by a quarter of an inch and the periphery by half an inch almost but it's not a waste as it was scrap anyway. Lovely metal.... just rolls off with a bit of rake on the tool, not what you usually do for brass.

Is the swarf (?) dangererous without the guard on,Stanley? You won't type nearly so fast with fingers missing...I hope you are not being cavalier!
Oh, Deadly tells me it's your eyes that will get it, not your fingers...is Jack set up to be a guide dog? Will you find some other way to protect them...swimming goggles, welding helmet, national health specs..perhaps?

I wear glasses so no problems with my eyes. Biggest danger with swarf is getting bits in your socks, majes walking very uncomfortable. A lot depends on how sharp your tools are, good even swarf behaves itself when it comes off the tool. After over 70 years I still have all my fingers, must have been wonderfully lucky eh?

Lateral thinking…..
I think you might like this one. In the course of making the gear wheels for the 1927 lathe I found myself with a blank ready for gear-cutting exactly the right size for a 95 tooth wheel. Remember I have a 180 tooth worm on the tangential gear so I started factorising….. 180 divided by 95 gives 1 and 85/95. That factorises to 1 and 17/19. in other words, one full turn and 17 holes on the 19 scale on the dividing plate. Only problem is that there is no 19 circle. So I decided to make a second plate and divide it into odd numbers of holes as and when I needed them. The problem then arose, how do you divide a circle into 19 if you haven’t a handy sized gearwheel like a 38 tooth or a 76? I thought of lots of fancy ways of doing it but then went onto a kids learning site and made a pie chart with 20 segments and printed it. That’s right, 19 dividing lines. I shall make the plate, stick the pie chart on the face and drill on a circle into all the dividing lines. Smart and easy or what?

Did you spot where I went wrong? I was thinking of a linear scale, 20 segments is 19 dividing lines. Of course a circle is different. I drilled the plate and counted the holes.... 20! Back to the drawing board!

Alright, I got the number of segments wrong but the 20 hole circle will come in handy one day and I have enough room to get the 19 hole circle in so I shall repeat the procedure this morning. Here's the 1927 lathe demonstrating how handy a good overhead gear can be. Once you have set it up it's dead simple. The small clamp is a temporary traverse stop. I shall make a proper permanent one with a fine thread on the stop.

Arrrhhh,Now I understand what the overhead stuff is for,very clever(not me, the machine)!!

Good lad Tom! You just knock the belt off the mandrel pulleys and so the chuck isn't driven, you just postion it by hand. You can adjust the depth of the holes by using a stop on the bed. The holes are always parallel and on the right circle. I cut the 19 circle this afternoon and fitted it to the Dividing head so we're all ready for gear-cutting the 95 tooth wheel. I've left until tomorrow as it will take a while and I like to finish once I have started, less chance of a cock-up. I shall make a proper stop for the lathe bed.... the clamp works OK but I want something that's in keeping with the lathe. I have one that was made for another lathe, it's made of gunmetal so I shall convert it to fit the 1927.

This looks wonderfully professional but is actually a picture of a cock-up caused by not thinking straight. This should have been a 95 tooth gear.... When I finished it I found I had 98 and a half teeth! I went back and checked everything and found out I had miscounted the holes in the 19 circle on the division plate. I had been counting 16 instead of 17. Ah well..... So I banged it in the lathe and re-cut it as a 90 tooth gear, nothing wasted apart from a bit of time and metal. Must count more carefully........

I had a bit of a rest from gear-cutting and modified this bed stop for the 1927 lathe. Next gear is set up and ready for cutting tomorrow. 110 teeth.....

The dividing head has a new division plate. I needed a 23 circle and hadn't got one so I went the long way round and made a new plate with nasty numbers. 23, 21,19 and 17. That should solve a few problems in the future. Now I can cut the teeth on the 115 tooth wheel.....

Are you sure you are not becoming a wee bit eccentric Stanley?
(please note, I have nowt against being eccentric! You go for it! I just wonder what the neighbours think. Other folk collect Wedgewood and First Edition Books.....)
get your people to phone my people and we will do lunch...MAZ |

Probably Maz but who cares. Given the choice of doing something mindless like sitting for hours with a computer gane and making something useful with my hand and eye, give me the latter. All eccentric means is different, slightly out of orbit. It doesn't half pass the time usefully! Someone will be doing a job with the dividing head in a hundred years and they will recognise that a good fitter had it at one time because that funny number they need is there on the spare plate.

I'm still on with the gears, we're getting there now. It struck me me today what a great time-saver the slitting saw can be. Cutting three inch slices with the hacksaw is a young lads job!
