Casting Type-Founder Matrices on a Monotype Super Caster
« on: July 26, 2017, 07:24:57 AM »
Typefounder matrices, one in a time there was a special holder for this, made by Monotype.

Drawings of it can be found in the books of parts... I never encountered one... Are those all disappeared ?

Matrices are plenty, so the will casting them is there. Dan Jones of the Pigment Press in Ontario Canada has done quit some effort to solve the problem.

It sure is not finished, and will be perfected, but here a little film on Youtube:



The face involved is 18D Hercules, a very bold face, a little part of the legacy of a Belgium typefoundry.

===============

Further experimenting: 72pt casting from typefounder matrices:



To be able to cast these 72pt matrices, the mould has to be changed a bit:

The top plate of the mould needs to be grind down, until it is down the mould opening.




 These taper pins could be made shorter at the wide end. Monotype had a reason for them: to make sure that the mould pieces would align properly.

Presently I'm in Poland. Took with me the attachment Dan Jones made for us.

Casting typefounders matrices... This has been accomplished.



A complete font has been cast of Brygada 36 point... An old Polish font, these matrices have been idle for at least 90 years...





The head of the Supercaster has been raised by tubes, at the same time the gliding mechanism for the matrixholder, in this way we have enough room to accomodate typefounder matrices.

In the past Monotype made an attachment for typefounder matrices, but s far as I know, none of them have survived. I never saw an example... only some drawings in the book of parts.



In this way we will be able to re-use all the matrices of a former typefoundry in Warschaw. Some 2000 cases with matrices  are waiting for us... At presently a special room has been cleaned and work is in progress t store alle cases, so that it will be possible to make an inventory of this all.

Well, maybe not all of them, but those for 14 points onwards...
See, this holder requires the Monotype display mould (either 14...36 or 42...72 points) to work as it relies on the display bridge and head. Smaller sizes (6...12 points) must be cast on a composition mould with an adapter plate, but attaching the display bridge is impossible. The head is completely different too - actually, two slightly different heads for 1x1 small composition mats and (1, 2)x(1, 2) large composition mats. The latter has a spring for putting additional pressure on the matrix. The mat holder will have to be different as well.

Wow, great work John.

The way things are looking this work could eventually benefit the whole letterpress community.

For the sizes 42pt up to 72pt, the upperplate of  the mould insets, needs to be grinded down, this was shown in the first part of this item.

For the smaller sizes... I think the other head can be raised also, and it will be possible to make another surface under it, to accommodate typefounder matrices for smaller sizes.
