Sliding Sash moulding

[RossJarvis]

I'm refurbing some sliding sashes and it looks like I'm going to have to replace a rail and stile. Most of the construction looks reasonably do-able apart from the moulding on the interior around the glazed areas.

I haven't got a picture and am trying to find a router cutter that would match the existing moulding. The shape is fairly shallow and has a stepped then convex radius shape with a flat leading to another step (if that makes any sense at all!!) a bit like an "extended ovolo" shape.

Does anyone have the fairest idea what I'm after and where to get a cutter? I've looked through the Trend and CMT catalogues but haven't found what I'm looking for.

if its only two pieces rebate plane and a scratch stock (assuming its hardwood) then finish off with abrasives

Sounds like it's a lambs tongue.

Is it like this?

There are no router cutters on the market which will match most trad window mouldings. You make your own, or fake it.

Sounds like you will have to do the mould in two operations, perhaps It will be be easier to match the extended ovolo
you require.

Alternatively, you could break the moulding down into individual sections that can be planted on, that would make life simpler. And in the final analysis it doesn't have to be an absolutely perfect match, a few coats of paint means that close enough is good enough. If you're stuck then I'm not too far from you (south coast, midway between Southampton and Bournemouth) and I'm happy to help out with spindle moulder, a decent selection of router cutters, and if all else fails we can use my hollows and rounds!

Good luck.

It's most probably an ovalo. Probably the commonest design of moulding plane, as they stayed in use for just this sort of odd job long after bulk production was all machined.

But if you really don't want that easy way, for the small amount you need, you could rout two rebates then make the curve by planing off the arris between them, rounding it over, and sanding.

Thanks for all the replies guys I'm well chuffed at all the help you've given.

I've now realised that all the other windows I've done were "thumb ovolo" and didn't notice this one was just a standard one. (really must replace the batteries in my specs).

I had thought of cutting a couple of rebates and using a shoulder plane and abrasives to get the shape.

However, now I've started stripping this one I've discovered this sash is a modern replacement for the matching upper sash (which has no rot and is only about 100 years older!), seems to be made of wide grained "whitewood", isn't as finely made and probably needs to be completely replaced.

As someone else is paying we'll probably farm it out to someone else.
