Now my question. When candles are made in this way say in a 1/2" id tube a 1/2" rammer can not be used, can it? the rammer would then not fit freely in the tube. It might sound obvious but is it best to use a smaller dia rammer? or cut out a section of the rammer? or possibly use a square section rammer? How are candles made this way professionally?
I prefer to do it this way as it seems that the sawdust delay acts as a wadding to give a better shot and always ignites the star

I found this out as I had some misfires when I examined them the following morning. So it seems like the extra pressure buildup caused by the sawdust allows you to use smaller stars, and less BP. I'm sure a 1/16th visco fuse running down the side isnt going to affect this too much, but if you are worried about it then use a small drill bit to drill down the side of your rammer, so you get a groove for the fuse to fit into.

I might try a square section rammer which would leave a gap for the fuse down the side, after all i'll only be ramming sawdust.

Also I'm sure I heard somewhere that a mixture of wax and sawdust can be used in place of clay as a plug for tubes, anyone know much about this?

Whilst your offer is very nice, please take some friendly advice and read through the posting etiquet thread before proceding with more posts.
There is already a number of threads on roman candle construction and tecniques which this would have been better put in and you will see that there are also a number of diagrams posted too.
Please dont think Im being harsh but I really suggest reading then reading some more THEN posting as you will find nearly all the answers here already and you wont come across as someone who cant be bothered with the basics first.
Hope to see you on the forum more

They would put in the delay and ram it, then tear off a piece of blue touchpaper from a sheet and ram that in. Then they would put in the star and a scoop of lift, then if I recall a bit more touchpaper before the next delay increment was rammed. So basically the touchpaper forms a barrier between the star and the delay. I never asked about this but I assume that it was to keep chlorate stars and sulphur containing delay apart.

Similarly, a chlorate based star could be used in a Roman candle with BP lift as it is not an admixture. Whether it is wise is another matter.
