Hello everyone
I recently purchased a Master Caster and am now in the process of converting my RCBS molds and a few Lymans to the Master Caster configuration, I purchased some extra hardware from Magma for that purpose. I also have a new Magma mold that serves as a reference point to know what my modified RCBS/Lyman mold should look like.
Here and there I found some informations on how to proceed with the slots and some discussions about drilling all the way thru the block or not, but now that I started the job I notice there are some tricky details that I would like to know of, in order not to destroy a good mold.
I already opened the slots of my RCBS mold with a file and the mounting hardware fits into the slots.
I have the following questions:
1. How do I remove the sprue cutter bolt stop? Do I need to file/mill it away, or is there a more convenient way to remove it? I believe it is in the way for the Magma sprue cutter.
2. Where should I drill the hole for the sprue plate pivot bolt? I plan to follow the Magma design and mount the complete bolt with tension spring, Magma provided the spring & bolt assembly. I could use the original hole from RCBS and drill it through the entire block, but hesitate if the RCBS sprue cutter bolt pivot hole is in exactly the right spot, is not 100% clear to me. If not, I would drill it in the other half that originally had the sprue cutter stop.
3. I have exactly the same questions for the Lyman mold, except that these are shorter and this raises more questions, They are too short for the mounting brackets that slide in the enlarged slots, so there is not enough metal to drill and tap inside the slots to attach the brackets on both sides of the block. How do I have to deal with this?
Thank you on beforehand for your advice gentlemen, I would hate to screw up a good mold or having to buy additional molds if this can be avoided by a succesful conversion.
Kind regards
Mr Pebbles
