Mould MKII

SO I started making my new mould today, Its all glued up, clamped etc. The BendyPly isn’t glued down yet. I will do that tomorrow.

The set up is 600x600mm Squares with circles cut out. The spacer between the squares is 16mm MDF, the layout of the mould makes it a little deeper than 8″ meaning it can produce 14×8 snares.

It looks like the quality of the mould is going to be a lot better. The only problem is that its heavy as anything. So tomorrow I will glue the BendyPly in, cut it in half and add the hinges and L-brackets.


The Mould Begins.

OK so I have started to Build the mould. Well actually I have finished it but for this post i will show you how I constructed it.

First of i got 4 sheets of MDF approx 18” x 18” which I then Constructed a Circle Jig to cut out circles. After I cut out the circles i used some bendyply to make sure they all aligned and then glued up the mould. After this step I then proceeded to glue the Bendy Ply to the mould.

I made a mistake here by not cutting the sheets of MDF exact, and having the circle in the exact middle, as I wanted to attach Hinges and a lock type thing on the front for easy opening, but proved impossible with the way I layed out the sheets. I have overcome this by purchasing some 750mm long clamps and clamp it all up.  so i cut this baby in half and clamped it back together. The reason for cutting it in half is so that I can easily remove the shell once completed. also to compensate for the material the blade takes away i put a 1.2mm piece of plywood in between the two halves.

On a side note I made the mould 14×9 but one of the MDF circles was slightly out of round, which means the usable area is more like 5″ or 6″ deep. not a big deal as I plan on re-doing the mould later.
