Quote: "However I seem to remember that amongst much commentary and even the book itself that the Quorn does not actually sharpen drills"

On page 113-114 in the Quorn book it is all explained. (4 facet method).

Johs

Yes, I found it!

"Further developments in drill sharpening" by D.A.G. Brown. M.E. vol 215 No 4513 page 184.

This is a superior way to grind a drill. Try it!

I think grinding the drill is named "step rake". Anybody know the M.E. volum the article by Drown appeared?

Johs

Thanks Emgee.

Yes, I have that article, but he had a later article on grinding drills using the same equipment.

DAG Brown had a good series about sharpening drills by the 4 and 6 facet method. Later on he developed a better way (I think) to grind a drill. I can not find this artikel. Can anyone point me to the right M.E. number?

Thanks.

Thanks again. Have already sent a request for the drawings.

Thanks. Impressed of the quick reply!

The "Cross engine" is what I was looking for. Now I have to get some more info and drawings.

Hi

I have seen an unusual steam engine in a model exhibition wish I wold like some information of. I do not know the name, but the engine have cross at the top in witch the piston road and the crank is joined in some way.

I would be most grateful if any could show me a picture and/or perhaps a plane.

Thanks to everyone, I think I have all the information to make the sound Box, only one question or two. What angel should the needle have to the table and can I use some thick plastic as the membrane?

(Neste gang jeg er i Bergen vil jeg besøke deg i Laksevåg om det er i orden. Se HTM klubben.no hva jeg holder på med).

I have an old gramophone i am trying to restore. I have al the parts, but the "pickup head" is missing. I wonder if any could help me with some information and perhaps a drawing. ( It is a weary old gramophone with a big horn).

Sivtek

I will try to make a smal manometer and I think it has been a drawing and building instrukyion in the Model Engineering magazin some time ago.

I can not find the magazine, can some help?

Hi Rod

Afraid that I live far away. I live in Stavanger, Norway.

BTW. I and 3 friends are going to the the Midlands Model engineering exhibition next week (Friday and Saturday). Hope to see and learn a loot.

Thanks to JasonB for the information

Thanks

Sivtek

Thanks.

I bought the drawings about 5-6 years ago, converted it to metric, made casting models and did all the castings. I also made the boiler. Preparing and collecting necessary materials took about 3 years, building and painting 2 years.

I did use about 3/4 hour witch I thought was to long, but now I se it is ok

BTW,, how do you use the damper?

Sivtek

Hi I wonder how long it usually take to get an Allchin 1 1/2 traction engine ready to run?
