yup, moomshadow, it looks like what you have are the metal and felt weather stripping that accurate metal carries...i've never seen them installed on a parting bead...in fact, i very rarely see them at all in new england...i have a friend/fellow restorer who says he sees them all the time and he is in buffalo...i could only get a small photo of dfiler's parting bead and from that vantage point it looked like a spring loaded thingy....

it makes sense to install them on the parting bead but i have only seen them on the sash itself...i think it's odd that the meeting rail block not available in colors...

one way of getting around having to use the block is by making your parting beads out of a dimension that will cover the space in the meeting rail and still allow the sash to slide properly......

My theory on why the parting bead isn't simply made wider instead of adding a parting bead block...

With integral weather stripping, there is metal attached to the meeting rail on both the upper and lower sash. If it were as wide as the total space between the left and right parting beads, the metal would gouge grooves out of the parting bead when raising or lowering either sash.

With the metal parting bead block, only one the portion of the parting bead is wide enough to make contact and get scratched, and it is made out of metal. It is wide enough to fill the space and prevent drafts when the sashes are closed and locked, yet the weather stripping on the meeting rails are kept away from the scratchable wood of the parting bead.

Or perhaps for centering the sashes horizontally when closed, while still allowing a gap elsewhere for friction free motion.

Sound plausible?

lol, like I'm some kind of double hung window expert all of a sudden or something. :lol:

Oh... and another question:

Is the parting bead block adjustable in size? The ancient ones I have seem to be filled with putty. It is hard to tell what it was like originally with all the painting, denting, and patching over the years.

since you are replacing your parting beads, see if you can select a size that fills the space at the meeting rail....

the blocks are only available in one size as far as i know...that 'putty' may be the felt that has been painted over...the block is made of stainless steel tension spring with a charcoal colored piece of felt inside...one of the issues with using them is that they get painted over and may cause problems over time....

you ARE becoming an expert on window restoration!!

An update on my progress:

I've bought some 8' 8x1" pine boards to use for parting beads. A co-worker has offered to use his planer to get the boards to 7/16" thick. Then I'll run em through a table saw to get the 7/8" dimension. Should work perfectly. The 7/16" side is what matters most, it'll ensure a snug fit in the jam's dado.

Hopefully by the end of next week I'll have photographic proof of my first restored window... :D

I called these guys and they wanted me to order over $300 of the item to meet the minimum order quantity.
Is there any other place that sells meeting rail blocks? I've searched but with no success. :(

At least the Liquid Wood and Wood Epox from Abatron went well. The sashes are now square and rock solid even without the glass installed. Tonight I'll be glaxing and painting with linseed oil based products.

Also a success was the making of my custom sized parting beads. A few hours with a table saw, planer, and router and I've got exact replacements! :) (I don't own any of those tools myself but a friend helped with the first two and loaned me the router.)

Gee dfiler I'm sorry, I never ordered anything from them because I was able to salvage what I had. If you want I have two from the kitchen window that I took out. I'll gladly send them to you.

Hrmmm... where in Pittsburgh are you? I am thinking it would be cool to know someone local when we finally start working on our windows. By the time we get around to it you will be an expert. :D (I am in the north hills...)

Have you been to construction junction at all? I am thinking that might be a source for wavy glass.

The window is done! (minus the parting bead)
Week 117 - Restoring The Pantry Window 4
(lots of pictures :))

Thanks for the meeting rail block offers. I'm going to try ordering again to see if there was just a misunderstanding. The guy I spoke to had an eastern european accent that was a bit difficult to decipher.
