Good job on the wheels Adam, a few points if I may and hope you won''t take them the wrong way.
 
I raised this point in the Chain Drilling thread, the front wheels should only have 10 spokes, nothing is mentioned on the drawings about this and this is exactly why things like this need to be correct on beginners articles.
 
When bending spokes try to get a short tight bend, this can be done by holding the palm of the spoke in a vice then gripping the rest with an adjustable spanner held about 1/8" above the vice and give a tight bend rather than the "S" shape. They also look a bit thick again nothing on the drawing and could be one of two thicknesses going by the text.
 
The rear spokes don''t look radial though it could be the camera angle, looks like all the spokes should move one hole clockwis eon the rim

Don't think it is the camera angle - as they don't form a straight line with the axle bearing.

Just come back to this post. I agree fully with Jason's post, but then I have not even started to make the wheels, soyou are way ahead of me. I do have a query - Adam, we do not have any idea of what your knowledge of portables or model engineering experience is. Without some knowledge of the real thing it would be pretty difficult to get it "right" from the published info so far. I do have a couple of photos of portable wheels on my phone which I can post if it would be useful As far as the front wheels are concerned, while the words in the mag say they should have less spokes, I have seen the real thing with wheels which look like yours.

Sean surely if this is a model of a B,E & A portable taken from the etching in the first part of the series then it should have the right number of spokes, if it were just a freelance early portable then you could put whatever number of spokes you liked. As you say there are plenty of portables with the same number of spokes front and rear, though usually 12, 14 does look a bit crowded on a small front just compare Adams wheel with the etching
 
I was not knocking Adams work but pointing out that by getting the same number of spokes in each wheel the point I raised in the other thread had come true.
 
If you do want a few pics of portables then Station Road Steam always have a good stock to look at.

Hi, I've had another study of the photos, and I'm thinking that on the back wheels the spokes may be a shade too long, causing the hub to be slightly rotated clockwise in respect to the rim. Moving the spokes round one hole on the rim may make it look the other way. A photo looking square on to them would show it better, as the front wheels look OK radially.

The front wheels look as if they are a heavier duty than the back wheels with the same number of spokes in them.
 
Having said that, they do look a tidy job.
 
Regards Nick.

Hi There
Before anyone asks, the portable will continue in ME 4408.
This is to give me time to ensure the article is correct.

Julian,

fair point. I don't think anyone was knocking Adam's work. Actually, to be very pedantic, is this really a model of a B,E&A portable? the catalogue it is taken from is for Reading Ironworks, BE&A ceased to exist 15 years before that catalogue was produced. All of the illustrations of BE&A portables I have seen (mostly the ones in the recent book produced by the RLS) show very different construction.

The point about the back spokes being over length, hence skewing the location, seems to be correct. This just points to Adam making agood job of a poor article.

Hi all
I have tried to post some replies earlier but the computer went through the motions, but no posts appeared above untill yesterday when i tried from work computer which uses Firefow for its internet browers.
Have down loaded Firefox on my computer now. So, if it works your reading this.
Rright back to the point in hand.
 
When i first read about the CountryMan portable i thought it was perfect for me
as it had a "have ago with what you can find" feel about it. So i just filled in the blanks
to produce the wheels to the general over all dimensions.The number of spokes on front wheel was a silly over sight on my part as the picture on the front cover of the magazine
clearly shows. Spoke length on the rear wheels are to long because i didn't trust my maths when working out extra length needed for bending. Looking back now i should have bent first then drilled holes in a jig or something.
You may have worked out by now that i don't come from an engineering back ground. I've been into radio control cars and boats for years but really got more enjoyment from the building of them, rather then the using of the models. So to give a longer building project i bought a 3.5 x 12 lathe and a small Stuart kit to machine about 3 years ago.Cut my teeth on that one ,then bought an X2 mill and a Stuart 10D kit which i finished about
6 months ago. Was planning on putting this in model steam launch hull with a boiler, coal fired if i can do it. So i started looking around for Ideas and when i found the CountryMan project in the Model Engineer mag which i thought would be brilliant for gaining pratical knowledge on boiler making.
Thanks for all the posts when the artical gets going again I'll put some more pics up.

Good to hear from you at last Adam. The quality of your work looks fine you probably just suffer from being too keen to get on and there is nothing wrong with that.
 
This series is looking like it will be quite draged out at first due to the large amount of info for the beginner. The latest 4408 explains about the differing number of spokes & getting tight bends and I hope that the next one will show how a building jig is usually used to make up traction engine wheels to keep the hub in the middle and the spokes radial.
 
Don't give up hope just be patient and I'm sure the info you need will be forthcomming and you can be sure that any errors will be picked up by us more experianced makers so you don't have any wasted metal.

Nice to see this is continuing - I was starting to fear that because of the issues raised it was going to be quietly dropped - glad it hasn't been - was considering this as a project. However, will waite until I have it all before starting - at the moment am just doing it in my head and making mental corrections
