Hi Dunc

Like Martin I used a Sievert 2941 following the instructions supllied with kit and all worked fine. I too used short peices and rings of silver solder around tubes and joints with flux applied, but also did something i think is called "hot roding" where i heated the solder stick and then plunged it into flux powder to coat stick. This i used to fill any areas that the solder did not want to fill or flow into, using the heat in the job to melt the stick not the torch. The process took about 10 to 12 minutes to get up to the right temp, I watched for the flux to run clear before attempting to add any more solder/flux.

I'm very pleased with my efforts and the boiler steams very quickly about seven or eight minutes from lighting coal to 60 psi and running engine.

Just got to finish the the model boat to give it a proper run.

I also want to thank all the people that put stuff up on the internet and forums for us newbebies to learn from.

Thanks Adam

Hi

I want to have a go at making the Bobcat engine which has started in ME. Part two opens with "mill a suitable aluminium block", my question is what would be a good grade of aluminium to use. I have the book by Malcolm Stride on miniature IC engines which came as a gift for my subscription to ME. In that Malcolm suggests to use LM4 for the crankcase, but this is a casting grade of aluminium. I looked all over the drawings but can't find any reference to what type of material to use.

Also is there going to be published soon a cutting list (not sure if that's the right term) for all parts required to make the engine, so all material can be ordered together to save on carriage costs?

Thanks for replies.

Yes i do get alot of oil on the valve and piston rod exits so i'll turn up some different cranks with a shorter throw and trial them for a couple of test runs. Are there any signs i should look out for of under oiling the engine or if it seizes i gone to far.

Hi all.

Is there a correct amount of steam oil and can you have to much?

On my steam plant the oil tank empties in about 35 to 45 minutes, the reason for asking is because i'm getting a lot of cream coloured sludge from the oil trap.

Hi David

I made the wheels last year and have been waiting for the whole project the publish before starting the rest, so if you do decide to drop it a full set of the drawings would be good. May be just have a download off the main site.

Regards Adam

Hi all

Any chance of a few more pictures of finished components or close ups of the finished model, to make it easier to understand some of the text and diagrams.

Hi David

Now this series has started again do you think it will be in every other issue or will there be a long pause again as i'm really looking foward to making use of the wheels i made last year.
