Hi chaps,
Problem: my e-bay purchased lathe came without a cover for the head stock among other missing parts. Having got it working and able to access the wear in the bed which was minimal i decided it was time to fire up the furnace and make a cover.
The original covers were made of plastic and by studying the pictures on lathes.co.uk I created a pattern from mahogany salvaged from some internal doors.
Here's a picture

it's dirty because its been used to make a mold
and here's the results
twice :doh:

left image not enough metal in the pot and the right one not hot enough to fill the mold
I haven't done much casting in the past couple of years but it soon comes back to you what to what out for.
Repaired the pattern

And came up trumps with this beauty :)

That lathe will work much better with a cover that says "Made in England". Looks like you made a fine job of it. :clap: :clap: :clap: :D :D
Cheers :beer:

Originally I tried to build the cut outs into the pattern but couldn't work out how to do the casting in green sand. It could probably be done with sodium silicate sand cores which i considered learning. In the end I stuck with the green sand (home brewed) and cut out the extra metal using my wood working band saw. There's nothing wasted as the bits will go back into the next project.
I think it needs a bit more sanding.
What do you guys think, should I paint or leave au naturel.

Awesome work :clapping:

Just give it to Rob Wilson and let him do his camera smarts on it. It won't need no painting, only occasional pollishing. :lol: :lol: :lol:

I also liked how you showed the ones that did not work out :med: , thin sections in can be a pain .

Hi Angus,
It's an Acorn, Atlas 10f clone. Plenty of info on lathes.co.uk. Came with lots of broken bits but all the important parts were good. I've been gradually putting it right I'm not restoring it I'm making it work for me.

Hi Jon, i agree with the others, lovely job and looks like original part, I would paint it though :drool:
Cheers Mick

Very nice
It is a nice feeling when a good one comes out of the sand

Hi Jon
Your headstock cover has turned out good.
Well done
Cheers David
-
Jon, what lathe is it? And did you cast your own pulley (upper left)?
-
Hi Steve,
It's an Acorn which is a British clone of an Atlas 10f. Plenty of picks on lathes.co.uk. The pulley on the left is home cast as well and just like you I started with Dave Gingery's brilliant books and built his lathe. I have a half built shaper under the bench which I have to finish. I've been distracted for the past few years and not done much serious casting but now I'm back and going to finish.

Okay Jon, I thought so, and it's coming back to me :bang: I think I once said we have a lot in common -- Craftsman 12" (Atlas) lathe, Gingery lathe, shaper I need to get working, casting, etc. You made a really great pattern, and fine thinwall casting, and your cutouts were pretty sweet, too!
Looking forward to more!! :beer:
