Am not having any luck with Swissmar or anyone else regarding replacing the drive wheel on the Alpenrost. So I am considering options for repairing the two missing teeth. Is this a viable option:
drill a small hole where the pin used to be and tap a pin, perhaps a sprocket pin, into the hole.
Pin?? I assume that you mean sprocket tooth? I'm not an Alp owner, but if the sprocket is sufficently hard e.g. metal & you can tap a screw to retain a broken tooth, it should work fine. I don't imagine that the tooth is experiencing extreme loading in this application. The most common method of repairing a metal sprocket is to do a spot weld and then file it down to the correct shape (tooth profile). Can you buy a replacement sprocket? If you provide more information (description, photos, etc) you will probably get more specific advice. Good luck with your repair.

Hi Michael, After I saw & just read your post here, I remembered your email to me from Wednesday, September 07, 2005 11:39 PM Toronto time.It's in another coffee folder in my mail program.Sorry about that I completely forgot about it!! {:-/ I'm busy enough as it is with 2 jobs & answering all sorts of questions, shipping price quotes., etc.. I just left a phone message for you Michael a few minutes ago & said I'll phone you tomorrow about your Alp. {:-)
I agree, "pin" is the wrong term for what was there. It was a tooth, but I am considering replacing the tooth by making a hole and putting a pin in. I'd be afraid to solder, though. I can solder circuit boards, but this would require a much hotter iron then I have or know how to use, I think.
Craig -- just listened to my messages and sorry that I missed your ca.ll. Thank you for your number, though, but I will try to call you tomorrow (Wednesday). It is too late to call right now. Michael
You don't want to solder this, solder has too low a melting point for high temp applications & it would be hard to get structural strength with solder. I suppose you could try silver solder as a last resort. I was suggesting a weld or braise, if you couldn't source a replacement sprocket. A viable alternative would be to drill mating holes, insert the pin you mentioned and then bond the broken tooth with "JB Weld" (steel filled epoxy).

Thanks for the info about the sprocket being aluminum. The OP might want to check out this product (Durafix), if he can't source a replacement sprocket. It's an aluminum braise that you can supposedly use with a $15 hand torch. Unless of course the OP can find a neighbour with a TIG unit instead.
Hi Michael, I just called you again (3rd time, I know we're all busy these days, jobs/etc.), got your answering machine., so I didn't leave a message. I did some measurements & have a solution for you if you want to try it.
Please call me when it's convenient for you, but remember the 2 hr time difference, thanks.
