I like John Halls video about screwing the neck block to the mold.
Simple and seems to be very effective.
I'm stealing that one.

MDF machines well but it is not as stable as ply wood the nice thing about this discussion is that there are many ways to do this. We all seem to develop methods that work for each individual. As a machinist and tool maker my discipline is secure fixturing . What you want to do is have a way to make a process reproducible . So controlling critical aspect of the guitar goes without saying. what are they ? Symmetry Neck block location keeping sides true. I use high grade balitic birch plywood , and early used many materials MDF being one of them , and if you use spreaders the MDF will flex , and don't get them wet. Variable molds have issues but again do what works for you. Make an informed decision on need and affordability. this is my method I use this as it removes an internal spreader and secures the location of the sides should you have to remove the rim. https://www.youtube.com/watch?v=FcM3GErOI_A |

Mine require a socket and ratchet, so not super convenient, but I like the accuracy of the joints and low weight. Attachment: form copy.jpg

FWIW, my $0.02 - It's a bit more work initially, but I dowel and screw extra blocks top and bottom at neck and tail. Lets me clamp the blocks in good and solid, and keeps everything square. Just remove then after blocks are glued. Attachment: mold.jpg But I'm using these 'universal' spreaders now. Attachment: universal spreaders.jpg

You mentioned not needing a spreader. Sent from my iPhone using Tapatalk Pro |

John I like your mold for weight and efficient use of materials. What are the extra holes between the spacers for? Ed M |

Definitely NOT "A." I bought one and regretted it immediately. Home made ply from here on out. |

I think this is my favorite so far. I love those spreaders. Oh yeah, and the bench clutter. Just enough room for the job and no more. Makes me feel at home John Arnold wrote: The only solid form I have made was the first one. The rest are plywood with the spacer blocks, as Alan describes. Much lighter. I use two spreaders; one longitudinal and one across the waist. The outside profile is a uniform 2" larger than the pattern, which simplifies clamping the sides in place to trim the ends accurately.
  I use 1/4" bolts and wing nuts to join the mold halves. They are fully inside the perimeter of the mold.  In action.  |

John Arnold's mold....I'd love to understand the wood dimensions (material thickness, spreader height, considerations of height so's there is room left for kerfing clamps). The one dimension I have is for two inches for rim width, so I know the spreaders are two inches wide as well. Thanks! |
