    Hello all,

    I would like to know is there are a clock shop that sales ruby pallets for Vienna Regulators Graham escapements.

    Most of this escapement pallets are made of steel. I will receive a vienna regulator clock with a Graham escapement. The pallets of the ancor are made of ruby. One of then has some damage and probably I will need to find a new pallet.

    I don´t know is there are some clock shop for buy this ruby pallets. If this is not possible, also will be interesting to know if there are some Graham steel ancor pallets clock shop.

    Thank you all in advance for you help.

    Kind regards,
    Miguel

    TIMESAVERS sells ruby colored pallet jewels. ANY clock repairman can make steel ones and install them.

    Miguel, Meadows & Passmore in England offer synthetic red sapphire jewel pallets in three diameters for a little over 9£ each when you buy two or more. These look identical to the original pallets and work quite well. Part numbers are 0654 017515 (1.75 mm), 0654 020015 (2.0 mm), and 0654 022515 (2.25 mm). They also offer stick shellac for fixing them in place.

    Hi Miguel,
    Just ignore the people that either can't read or don't know the difference between a Graham and a Brocot escapement.

    I don't think you will find what you need 'off the shelf', but I'm sure you can find somebody who can grind & fit Graham pallets in synthetic ruby or sapphire. Isn't there a clockmaker in England that is renown for their complicated clocks with lots of jeweled surfaces? Maybe they can do it for you.

    Alternately, this maybe the perfect time to learn a new skill. I imagine that the raw synthetic ruby shouldn't be too hard to find and then all you need are some diamond wheels to grind the new pallets. Sounds like fun!

    Best,
    Rich

    Please explain the difference between a Graham and a brocot escapment, MC. I'm absolutely certain I'm guilty and I'd like to update my thinking and notes. Thanks!

    Hmm, my thinking is a Graham escapement has either a solid anchor or one with curved adjustable pallets. While a Brocot escapement has semi circular pallet pins. Could this be what has RC's knickers in a twist?

    Rich McCarty, thanks for the "doh" moment and taking time to read what Miguel was actually asking for.

    Miguel, please ignore the information I provided in my earlier message. Rich McCarty is 100% correct that you are looking for Graham escapement pallets fashioned from solid synthetic ruby or sapphire, and NOT half-round Brocot escapement pallets. Mea culpa, somehow my brain switched to the Brocot mode when you mentioned "ruby pallets" instead of really reading and understanding what you requested.
    Scottie . . Miguel is looking for curved Graham escapement pallets shaped like the normal steel ones in your typical Vienna regulator. Brocot pallets are half-round with a flat surface, and operate completely different from a Graham:

    Sorry for the quality but all I had handy. First pic is a Brocot escapement. the half-round pallets are easily seen. The second photo is a Graham escapement with adjustable pallets, both set into the anchor with a clamp plate and screws. No question which is which.

    As Rich says, the Graham pallets will need to be handmade from solid synthetic ruby or sapphire. I have no info regarding who can do that, hopefully someone here can provide a contact for you.

    Hmmmm; O.K. Just never seen them altho I have seen brocot pallets in a Vienna movement. So I guess they're fitted like any other Vulliamy pallet. Thanks HUB!
    In that case then I'd recant, "some clock repairmen could make these of steel. Many could not."

    Yeah, I missed that as well, and just assumed Brocot.

    I might also suggest to CUCO :
    We don't know and until you take posession of clock you also will not know the extent of the damage to the pallet. However I suggest if damage is not excessive you may be able to still use the pallet by having it refaced. Again I realize your question is, "who can do this?" and unfortunately I have no recommendations as to who can. Just a thought.

    If you get lucky, the damaged pallet may be able to be reversed and that would let you resurface a new face. I hope you turn out to be lucky!

    You would likely have to trade sides too.

    I anticipate no need to swap sides. If pallet is entrance - give entrance lift and vice versa. If damaged pallet isn't broken off however, I'd make measurement of pallet span before removing as it may be correct and that would aid new setup. Opposite pallet may need moved to restore original gap.

    Thank you very much to all answer my question.

    I will receive in two days the clock and then I will show you the escapent. It´s true that a Brocot escapement is not the same than a Graham escapement. Also pallets of Brocot or Graham escapements are different like can read in the answers of my question.

    I have a great book about escapement that I bought some time ago:
    Title: Échapements d´horloges et pendules"
    Author: Charles Gros
    Language; french

    Also, I think there is a interesting escapement book by Laurie Penman: Practical Clock Escapements (language: english)

    Other little but highly recommended book is:
    Title: L´Echapement à Ancre
    Author: Charles Gros
    Language: french.


    Thank you very much indeed for all.

    Kind regards,
    Miguel

    Penman is very much my bible on escapements. I have others that reinforce Penman's but I always go first to Penman. I anticipate very much your receiving your new clock. I hope it's better than you anticipate!
