Somebody asked me how I make my reamers for my live steam model loco's. I put together this short video that gives some of the tricks and methods I use to make life a little easier. Using these taper reamers I get a steam-tight steam-valve with little effort.

Hallo, Very nice video. May I ask why applying soap (I think dishwasher soap) to the part before the heat treatment? Tx

@Lukers_tinkering Жыл бұрын

Thanks for watching! The soap is too help with scale formation during heating. This makes the part easier to clean, which helps with determining the color when drawing the temper. It also helps to a lesser degree with surface carbon diffusion, which will soften the cutting edge.

This is a nice video, I need these for clockwork and originals are very expensive, for hobby to much mony, I have a lathe so I can made them easely, what steel do you use ? is needs to be suitable for hardening. thanks for help.

@Lukers_tinkering Жыл бұрын

These were made using silver steel. But i have made similar reamers from good quality hss drill bits. These were ground on the lathe using a micro die grinder. This might be more suitable for your application.

Cant really tell from the video but did you make everything but the cutting edge recessed so it only touches at the cutting edge? Want to machine some dies to swage airgun slugs.

@Lukers_tinkering Жыл бұрын

Yes but the design for softer alloys, typically used for airgun slugs, is different. The material will gall and cold weld. You should use a forming tool or a large rake on a cutting tool.

Thanks for the video, it seems like a useful thing to keep in my mind. I am building a 1/8 scale Shay locomotive and learning a lot. When you are milling the flat, do you go half the diameter or to something else?

Hi, you need to go to half. I normally leave a pip on the end as a guide. If you don't go to half, the force needed to cut becomes much larger.

Naand Luke, dit is gaaf om 'n mede SA stokperdjie masjienis hier op youtube raak te loop. Ek is natuurlik nie so gevorderd soos jy nie en ook nie in die stoom masjien lyn nie, maar maak graag my eie gereedskap daarom dat ek op jou video afgekom het hoe om die reamer te maak. Goeie video en raadsaam. Kan jy my verwys na n maatskappy waar ek "silver steel" of enige tool steel/ drill rod ens kan aankoop asb.

Hi Sjoerd, ek vra maar verskooning as my Afrikaans spelling nie perfect is nie. Ek het lank lass iets geskryf! Ek kry my silver steel van JKM of Ambro. Die nuiwe staal moet a paar keer warm gemaak word om did hard te kry. Die oue goed was baaie beter!

Leuk om eens wat Afrikaans te zien. Niet hetzelfde als Vlaams, maar zeker begrijpbaar :-)
