Dear Sundial List, In my last Email - I suggested that the internal involute gear could be generated by a rack shaped cutter - this fails due to interference. I knew this! Sorry. You could just use a hand ground tooth shaped cutter, and still use the mill as a shaper to make this part. Or make the corresponding negative using a rack shaped cutter, and mold the positive from it.
Sorry about the error. - Ben Hoffmann Content-Type: text/x-vcard; charset=us-ascii; name="vcard.vcf" Content-Description: Card for Ben Hoffmann Content-Disposition: attachment; filename="vcard.vcf" Content-Transfer-Encoding: 7bit Attachment converted: MAC Hard Disk:vcard.vcf 1 (TEXT/ttxt) (00009978)
