It is a 2 cylinder double sided beam engine. A bit too big for my small machines, I will try to attach the plan

Looks good, David.? What's the engine you're building? Mike

I have eventually got round to machining the flywheel, I opted for drilling and boring 4 x 40mm holes and mounting it in my 4" x 4 jaw scroll chuck as suggested by davesmith1800. This took a while but

That is a new one. I have place to put morse drift key on Aloris Thank you Dave

If you have more mt2 tools than mt2 QCTP holders... -- Bruce Johnson The less a man knows about how sausages and laws are made, the easier it is to steal his vote and give him botulism.

I think miss something Why do need remove it? Dave

Yea - used one of those too, until I made this.? So much quicker to just drop it in and pop the arbor out...

You could also use a regular 2 jaw puller with a short piece of rod. Paul M

Tried that... they seemed a bit? flimsy for some of the mt2 arbors I had. I even mod'ed them to get rid of the thin section. Plus like all gear pullers they're a bit of a pain to deal with. With

This is yet another variation of a fusible alloy which is manufactured by Cerrobend and other smelters. And yes it is pretty strong and can be brittle. An AI search disclosed that Cerrobend “is a

Cerrosafe should be strong enough though I have never tried it like that. I have used it making chamber casts in firearms. Depending on the application, there may be enough "sprue" left over to turn

From their site, it initially shrinks, then expands a little after it solidifies: < https://boltonmetalproducts.com/products/cerrosafe-bolton-160-190 > Other thing, 1/2"-20 is a UNF thread,

??? SO is Cerosafe strong enough to pour into a threaded hole & then cut a slot & unscrew it ? Do ya have to use some kind of release agent ? From what little reading I just did ( wikipedia ) ,

Roy, Thanks for mentioning Cerosafe! I had forgotten about this method! Dick

Have you thought of using something like Cerrosafe to take a casting of the threads to better determine the threads? Just a thought and not sure that is what you were trying to do. Ron

Hi Paul and other for feedback. My Jupiter 1 pencil sharpener has only a cut edge on one side. I think another model has on both sides. As I have measured it, I think all screws are in inches, the

Most pencils are made of cedar - here's a link with more details: < https://pubsapp.acs.org/cen/whatstuff/stuff/7942sci4.html#:~:text=Red%20cedar%20from%20Kenya%20and,grain%20of%20the%20wood%20used.
