Machining the Model Stickney Engine with Lathe and Mill

How I machined the casting I made. This is a large casting for my machines so some unusual set ups were used. You can see the casting being made in one of my other videos-Metal Casting at Home part 10

how did you referenced it for the first cut/milling if there is no squared edge to start with?? did you use water level :-), I'm only starting and know that in woodworking it is much easier just use a planer on one side and then you cut the rest..but here..

@cleric022684 As I know that the pattern I made was accurate I could usue the flash line as the vertical datum.Once the first surface has been machined this becomes the datum for the hoizontal.

That "slot drill" as you call it is also, in the trade, called an end mill. A two flute end mill works better for boring holes than a four flute mill, because the flute normally has a void in the center which makes it nearly impossible to push through material without pre-drilling. A center cutting end mill will work well too, though much more expensive.. What kind of vertical mill are you using? It looks rather old. Built like a tank of course.

@cdickenson64 Here in the UK two flute cutters are known as slot drills and 3 and 4 flute ones are known as end mills. As you say its not possible to drill (or cut a blind slot) with a 4 flute cutter.

Mill is a Raglan, very sturdy.

I don't think all this work was needed, if the part can still be bought. If you can't buy the part because it's outdated and no longer available, then yes. Think how much time you spend just to get it just right.

@Ryuuken24 You're missing the point. This is my hobby and I enjoy making things even if it can be bought.

You have no idea how much you have contributed to the society by posting all this vids.

[oicub2]

you would make a great teacher

Also god damn you need a co-ax indicator and a knee mill with decent travel. They can be had on eBay for about $50.

God damn those are some shitty chips. I would not want to machine cast condition metal all day. Thank god for 6061-T6. By the way you can artificially age aluminum in an over at around 300 degrees. If you start hving gummy chip problems or material strength problems that could help a lot.

Intresting use of your machines , never seen or thought to use lathe in that fashion.

This " is not" a put down , i give you credit for coming up with set ups to get the job done.

[Truscharu]

Amazing work you are very good

[vanzonhl]

i like seeing things made !! :) thanks a lot !

(nice trick with the sticky pin btw)

@giriisindahouse agree yesterday I subscribed, i think because link from instructables and today I watched over half of his videos in one go and I'm not even interested in casting, more in machining :-)

[cleric022684]

@Ryuuken24 yes man ur missing the point :-)

[cleric022684]

@myfordboy you nailed it! But you always get few of these commenting, thank you for all your videos, watched 30 of them just today already and continuing :-)
