Intaglio Press Enhancements






I made a good sturdy plywood base for the press, to which it is attached by cleats at each corner of the frame.

The advantage to this is that the frame is securely and evenly fastened, rather than being clamped directly to the benchtop on just one side, so there's less chance of racking the frame when it's under pressure. Also, the plywood base is easier to clamp (or screw) to the bench.



Also, my friend Nick Turner (https://heorot.co.nz/) helped me to swap out the crappy little hand-crank for this greatly superior wheel, a cast iron pulley wheel from an old pump.

And by "helped me" I mean Nick did all the work from start to finish, while I stood around and watched.

Baren

The components
All the bits together
A baren is basically a palm-burnisher for relief printmaking. The traditional Japanese ones are made from coarse-twisted cord glued spiral-fashion on a lacquer-laminated card disk, the whole being wrapped in a broad bamboo leaf to reduce friction and simultaneously create a hand-strap.

My version replaces the lacquered card with hardboard and the twine with small glass cabochons, which removes the need for the friction-reducing bamboo leaf. It means there are fewer, broader "points" than on the twine version, to transfer the ink from the plate to paper, but that has its pluses as well as minuses.
It looks kind of delicious, don't you think?

The cabochons are glued to the hardboard with epoxy. I've used the 24-hour cure super-strength stuff, but mainly for its extended working time rather than for its mechanical properties.


The glass cabochons themselves aren't precisely sized, which would make getting a perfectly level surface difficult (or impossible) if I glued them directly to the hardboard disc. So, instead I laid them out flat-side-up on this silicone baking sheet, added a blob of epoxy to each one, and then laid the disc down on top of them. The unevenness of the cabochon thickness is taken up by the epoxy resin, so it no longer matters that they're all subtly different. 

Conveniently, the sheet has these concentric rings printed on it, which made it a simple matter to keep everything centred.

It would be usable in its present state (once the glue has cured properly), but I intend to add a shallow wooden dome to it, both to make it easier to hold, and also to ensure that my hand pressure is being distributed evenly across the whole face of the baren. I'll also be able add a hand-strap, which means that I won't have to divert any energy to just holding on to the thing.

I'm getting really impatient to see how well it works. I must hold my enthusiasm in check until everything is properly dry.

A few days later....

Shellacked oak hand-pad

Delicious-looking glass cabochons,
looking like glacé cherries.
I've finished it off now, with the addition of a fairly hefty shellacked oak hand-pad. The whole thing is about 100mm in diameter.

I've only given it one outing as yet, and a fairly perfunctory one at that, but it was sufficient to give me an idea as to how to improve it. These cabochons are 20mm in diameter, and I think it would work better with more and smaller beads. To that end, I've ordered some 8mm and 12mm cabochons, and when they arrive I'll make a couple more and see how they compare.

I'm feeling quite optimistic about it.

So, now I shall have to get on to cutting some blocks, and getting some decent light-weight paper to print on — the baren works OK with heavier paper, but it's definitely more hard work, and the printing isn't quite as crisp.

Commercialism!

I'm not good at selling my skills, owing to having a pathetic timidity and a morbid fear of rejection. Having access to examples of other people's work from all over the world via the internet hasn't helped the situation at all, since it just grinds my face in my own perceived mediocrity.

Still, having said that, I know I'm not the most terrible craftsman ever, and it would be nice to make a little bit of money at it. Vast sums of money would be even nicer.

To that end, and as a tiny beginning, I've opened up a shop on Shapeways to sell off some of my digital 3d designs. It's at https://www.shapeways.com/shops/mojobobdesign

To begin with, it's some bits and pieces related to my interest in wargaming miniatures, but I'd like to expand into other realms, such as jewellery design, statuettes and what-not.
