Oh!!!! very nice job jor2daje!

Yes, people cut steel and also many exotic metals with Sherline machines. Of course, very little at a time is the trick ;-)

I can see you are well equipped!

Thanks LeMaudit forgot to mention that seeing your mini boy and reading some of the stuff on what I guess is your website definitely swayed me towards sherline.

That's awesome, no more complaining now.

I can assure you that you will still love epoxy. It attaches things without threads, seals stuff, and fixes your mistakes.

Very nice! Is that a compressed air motor, what's the scale?

That's what ultimately convinced me too, he needs to ask for commission :D

Yep, no more "I wish I had a lathe to make this" whining :)

Definitely, and machining things in sections then epoxying them together will allow more complex shapes to be achieved. I also want to look into the possibility of making rough epoxy casts then machining them down, though as the material is thermosoftening it might not work so well... maybe a small cooling fan can be made.

Not really similar, much larger bore and lower rate of fire. If you want an impressive large bore rapid fire cannon, check out the Russian AK-130:

Ya it's a compressed air engine, the cylinder with one hole just slides on the main body with two holes in it one with hpa which drives the piston on the power stroke and the other one is open to allow air to escape on the exhaust stroke.

The whole thing is about 3.5" long 2.5" tall and 2" wide, it's .25" bore with a .5" stroke. Everything is aluminum except for the outer par of the flywheel which is mild steel, the cylinder liner which is brass, the piston which is stainless, and the valve and nipple which I didn't make but are stainless.

Haha enough details? :D

Indeed, my curiousity is satisfied...

Although... I'll wager a video of it chugging away happily would be most pleasant :)

A cooling fan won't work well. You'll want a cooling fluid or lubricant. Even water in a spray bottle lightly misted onto the epoxy will help stop it melting when you try machine it. Some light oil that wont affect the epoxy would be even better.

I've dragged a new table into the workshop, now to bolt it down.

I've been told I need to play with soft things first before going hard... first project will be to attempt to replicate the "dimply" pengun, if I can master that I should have the basic skills to get me going :)

Interesting, something to try eventually.
