Hi Guys,
I had previously fabricated a saddle stop for my Raglan 5inch Lathe, which performed perfectly, however every time I looked at it didn't fit in with the rest of the lathe. It reminded me of that piece of wallpaper where the pattern didn't match up properly. No one notices it, but you know its there and every time you sit down your eyes are drawn to it.
Decided to cast a new one that was as near as possible to the original. Out came the drawing board and a sketch was prepared.
-
A pattern was then required. In the past I swore I would in future only use hardwood for pattern making, so it was off to the garage to select the hard wood. I found every size possible that I didn't want, and came away with a piece of old pine, and realized I was in for a struggle. I milled out the rough shape, sanded and shellaced the pattern, unfortunately this raised the grain, and required several more treatments.
Next I went on the net to view pics. of the stop, and discovered the item was tapered from top to bottom viewed from the front. Back to the mill to apply taper to the pattern.
-
The pattern was parted, and pegs and holes made to locate the top and bottom halves together. The mould was made up using new facing sand, and the casting poured.
-
The casting turned out well with no surface blemishes.
-
The casting was fettled and then machined
-
The stop was then given two undercoats and a top coat of paint to match the lathe. I was quite pleased with the results and can now look at the lathe with satisfaction.
Cheers David

Nice job David,
Does the screw knock the automatic feed off?
Cheers.

Phil, yes the screw does knock off the automatic feed, and is very positive.
Cheers David

Nice job :thumbup:

Very nice.

Very pretty!
How does the mechanism works? I have one dog coupling on one small lathe and that works only towards the chuck.

Hi Pekka, there is a push rod in the apron, which engages with the bolt in the saddle stop. When this rod is depressed it releases the apron feed mechanism, and the saddle stops.
Cheers David

Thanks Guys for all your comments.

Looks bloody great, top job on both the post and the casting. Thanks for sharing and inspiring us that want to start casting.

Looks very in keeping, nice period style and far prettier than the genuine article.
I bought a genuine one off ebay a bit back for use on my Little John Mk2, of course my lathe does not have the auto feed cut off feature.
I wonder if I could fit a Raglan 5 inch saddle to my lathe if I could find one.
