Lake Oswego, OR - Newton's 3rd Rocketry is pleased to announce they are
now stocking super-heavy duty rail guides designed to work with Unistrut
rails.

These high-quality rail guides are made from Delrin(tm), a light-weight
plastic known for its low-friction properties and its resistance to wear.

Delrin(tm) Unistrut buttons are the perfect complement to those
larger-than-average projects.

Priced at $10.95 per pair, plus $2 shipping and handling, these
high-quality buttons are bargain-priced!

These and other items can be purchased through our web store at
http://www.newtons3rdrocketry.com/shop/

My mistake forgot to set an inventory level.... They are there now.

Are all "unistrut rails" identical?  Or do you see variation in them at
the different flying fields?  I'm just wondering if any particular
vendor's "unistrut buttons" are guaranteed to work at different flying
fields...

I think Unistrut is built to a standard dimension.  Jim Stanlick turned
a bunch of these out of white Delrin some years back, they were only $1
each.  I miss that pricing now.

At first there was just one planet. And then there were two...

Rocketry Planet (http://www.rocketryplanet.com) and now Our Planet
(http://our.rocketryplanet.com)!

(Going from memory on what a friend told me)

Not all Unistrut is identical.  I believe with width of the channel, and
the flanges, are standard. What varies is the depth.

Go to http://www.unistrut.com/Browse/cat_pg.php?P=S00_Channel for images
of the various sizes (looks like 1 5/8" is the standard width)

The lip depth is some times different if you purchase a brand other than
real P-1000 or P-3000 Unistrut, (I have used both). If the guide lip
depth is cut so it fits standard unistrut, there should be no problem
with the off brand strut, as most off brands have less lip depth than
the standard Unistrut brand.

These are designed for the 1 5/8 series UniStrut.  There is now a
drawing on the website with dimensions.

Do you happen to know if they'll work on the MDRA rails?
    Thanks,
