I'm out now,

need to find somehwere more forgiving

Wow thats strong words no wonder beginners dont want to ask on forums anymore, some people feel so above us !!!!!!!!!!!

There was nothing wrong with how or what i asked un my mind, having just read the links from jon i am amazed at how important the dimensions are to what was before today a simple wheel.

I really truly hope you never get the need to ask a question to any one about something you dont understand, and dont forget dyscalculia might not be in your blood but it is in mine, should i really have to announce that?

Well at first i thought people are going to go well its 3.5" doh, but since when in life has any size that has been quoted is correct to that size? i have 2 size 9 shoes that are different :-D
so i am taking 3.5" to be inside the rails and nothing to do with wheel track and also my question i suppose is 3.5" is it 88.9mm or is there an accepted figure allowance of that?

@Jon, thats mint, you have no idea how long i spent trying to find that type of info, brilliant thank you.

@noel, i wonder what dictates too tight with 4'8", is that the radius curves ? surely you could narrow the wheel track,

need to read on that, new knowledge.

@old mart, :-D i wasnt trying to be funny just maybe should have put some more text behind it, cheers all.

Thats a very fair time very considerate to others around the globe

Just to help me sort out sizes for the garden i am playing with drawings but i really want it to be accurate, long story but might tell at the next online mtg

What i really really need is the precise dimension of the 3.5" track so i can make a track gauge, or am i not allowed to do that?

Many thanks, Malc

this is looking the dogs

I was quite impressed with what collet blocks can do, i have orderd a set and inc 15mm collets and off we go

that my friend makes so much sense now, thank you

I never thought there would be so many methods, i have never enjoyed learning so much before

thank you

I have never heard of collet blocks, i shall go away and read up, thank you all, very helpful

malc

Brilliant thank you Jason

Hi

Take a 57xx pannier as an example (0-6-0), are the offside and nearside sets of wheels independant i.e. not linked via an axle to ea side on the real deal?

cheers Malc

Hi

Lets take a 15mm bar 100mm long, put in the lathe and cut 20mm in to leave 12mm stubs ea end.

Put the bar in the vice on the mill and machine a flat across the 12 mm end 4mm from ctr.

I want to machine a flat at 90 degrees to the first one on the other end, i would like it to be as accurate as possible, how would i go about this?
cheers

I know you get 25 video but are you restricted on total entrants? i ask because as i was in the 1st video sequence i can drop mine out to allow others in who did not manage last time

Malc

I had forgot about fusions sheet metal , cheers gary, that was sooo easy, although it came up with 69.7mm and i double checked the settings, the only bit i am not sure of is what the k setting should be, i put 33

wow, impressed, all my years of being a commercial vehicle mechanic are lost here , the closest i got to accuracy was a torque wrench :-D

Loving all this new info though

You really do need to know your materials in this game and not just a piece of steel covers all

Thanks for that Paul, i gave Jason's diagram a real good go over until i was fully conversant in how it all comes together and i really feel i have a much better grasp on metal bending, thanks to all.

Thank you Jason thats a great pic and helpful.

Thank Joseph as i think you hit the nail about home practise until its right, this is what i have done.

To get my req piece size of 12.5 x 50 x 12.5 mm i ended up with a 72mm strip, bending it a 11mm in from the edge with the tightest radius the bender could accommodate

i thought overall it would be about the same, but 4mm increase...wow

Does this sound right?

I started with 1.2 mm thick steel x 61mm depth.

I bent it in my Sealey 760 metal bender to start practising ready to make the chassis rails.

The top and bottom flanges are to be 12.5 mm wide and i bent at a line of 13.5 to allow for a 2mm radius.

Now measuring the total top to bottom and the 12.5mm widths (which were 13.5) it comes to 64.5, its grown, glad i got plenty of scrap.
