Thread: Stanley - Quality?
02/08/2018 18:38:17

I use the cheapo brushes from Wilko, don’t shed hairs and just throw them away at the end of the job, cheaper than buying paint brush cleaner and a lot more convenient.

I think there are many people who buy cheapo brushes and then throw them away at the end of the job, but a cheap brush will never give you as good a job as a top quality brush. The cheapies dont come anywhere close to the finish from a quality brush.

Whats the saying "you get what you pay for" and unfortunately Stanley and a number of other well know brand names are just supplying items they bring in from China, the price reflects it.

I use Purdy brushes, not cheap but superb quality, a decorating pro told me about them. They last a long time if well looked after, they dont shed bristles and they keep their shape.

Thanks Neil

I must admit I am enjoying it.

Well, not that far from having a working rolling chassis, the chassis and parts have been primed and painted and re-assembled. I mentioned previously that the drive assembly was noisy so I carried out a couple of mods. The motor plates run on the axles and they were mounted via a 16mm long oilite bearing, I have doubled the length of the bearing to 30mm to offer more support. I have also added a nylon guide roller at each end of the motor plate to prevent any metal to metal contact when the plate moves vertically with the axle suspension.

The mods have certainly reduced the noise and it certainly sounds better than it did. I also noticed that when the drive is running a little finger pressure at each end of the motor plate improves it further. I am thinking of adding an extension spring at each end of the motor plate connected between the top of the plate and the underside of the chassis top plate. I,m hoping this will load the plate and have the same result as some finger pressure does but we will see..?

As you can tell a lot of this is trial and error and working it out as I go but one thing is for certain, it is FUN.

Thread: Cast Iron bearings..?
29/07/2018 13:02:57

Thanks Ian.

Ady, I wasnt looking for the best but asked if CI was a good bearing material which apparently it is.

Thanks guys for all the advice, its much appreciated and I have learnt a lot from your replies.

When I have finished the little electric 0-4-0 (which is running on oilite bearings) I want to design and build a Class 22 Baby Warship which is a twin bogie / 4 axle loco. Whilst jotting down ideas for the design of the bogies, I realised that if I went with off the shelf oilites they would need to be modified to fit . This is fine but I thought why bother..? better to make my own bearings from scratch that fit the job, hence my interest in going with cast iron.

Thanks again guys.

Regards

Ron

Thanks Dave,

The bearings I will be making will be simple shoulder bushes with a bore size of around 5/8". This leads to another question, to achieve this "thin cushion of oil" what clearance should there be between the axle and bearing.

Thanks guys, when I am that stage I will turn myself some C/I bearings.

I did read this morning of someone building a 5 inch steam loco and he argued that cast iron bearings will easily outlast bronze bearings, dont know if that is true but thats what he claimed.

Thread: Lightning storm
27/07/2018 09:45:29

Talking of lightning/thunder storms, I live right next door to the village church and last year we had a mother of a storm travel straight over the top of us. We were sitting indoors and suddenly there was what can only be described as an explosion, as if a huge bomb had gone off.

The next morning it turned out that the church tower had taken a direct hit, the cap on the top of the flag pole was blown off as was the top parts of the weather vane. Two weeks later and talking to one of the electrical engineers doing the repairs, they found the revolving part of the vane was welded solid. The tower is fitted with a copper earth strap but the engineer said that they are not guaranteed to prevent damage. The church had to be re-wired as the wiring was wrecked with wall lights and sockets blown out of the walls but fortunately no fire.

The engineers theory was that the lightning struck the wet painted flag pole (the highest part of the church) travelled down and did its damage before the earth strap came into play. There was also structural damage to the top of the tower.

Just shows the power of an electrical storm, quite scary.

We had a storm back in April with forked lighting all over the place, I was stood outside watching it and that didnt have a lot of sound, maybe it depends on the type of lightning.

Thanks Brian, thats good to know

Forgot to say the axles I am thinking of would be from EN8 steel.

Is cast iron a good material for motion bearings, any problems with it..?

Gordon, many moons ago when we had a 1/4 acre veg garden, I had a petrol engine garden tiller where you could remove the blades from the hexagon drive shaft and fit on a pair of pneumatic wheels. There was a trailer you could buy to fit on the back but I never got one, I did think of building one but never got around to it.

Thread: DC motors

A "wheelie bin tug" well that is different Gordon.

I assume it will be ride on..? I know you intend to mechanically connect the motors will it be 2WD or 4WD..?

Please keep us posted with progress it will be interesting.


Regards

Ron

Thread: Lathework for Beginners
22/07/2018 09:50:57

Well I dont think Nylon 6 is the easiest material to work with, I am still experimenting but mixed results so far.

Andrews advice of cut slow with high DOC and feeds is certainly true. Its no use taking fine cuts with a low feed rate, it does not work. Its also true that the swarf just wont break and you have an ever increasing ball of it which tends to wrap around and hide the job. Parting off is also fun, it cuts ok but as yet I cant stop the outer edge of the cut having a thin raised wafer of swarf still attached. I found the easiest and neatest way to remove it is to use a slow speed and the tip of a Stanley knife.

All good fun.

I guess you are referring to my shed Bazyle, its a new shed and will be fully insulated well before winter. With the weather we have been having I have just not got around to it yet.
