Putting it together, acrylic welding the plate reducers and recess.

In most cases, often I opted to use smaller sized plates, yet to have many types of wooden magazines and it’s backs would be cumbersome and hassle. The better way is to have plate size reducers.

Now, this is nothing new, as these had already existed as a part of camera’s accessories in the past.

The article here covers on simple way on how to weld together the cut-out acrylic with its recess lips, so your plate would not fall out of place.

The acrylic weld that I used was the EMA plastic weld, which I utilise it with moded syringe. Refer to the image shown below.

In most cases, it is commonly read that you need the Weld-On solution, but it’s not commonly available in the UK, the alternative is the E.M.A., which is quite cheap as these costs me £2.95, which will work dozens of acrylic welding. You could find them in most modelling stores in town. The syringe you could also acquire from the same place.

EMA Plastic Weld

 There are several ways to apply the solution. As this is a low viscous fluid, almost water like solution; it could be applied with syringe, thin brush, and even thin rod. I prefer the former, though it requires a controlled pressure, in which I apply some blu-tac, or any sort of plasticine to have higher resistance onto the pump from squirting out too much liquid.

Syringe and blu-tac

Apply the blu-tac around the syringe, between the pump and the body, and test the resistance when pushing the pump down. A good firm application would allow 2-3 drops per second.

As you have only one shot to do this, as the contact of the solution upon the acrylic have immediate effect in fusing the plastics within seconds. Here’s a video I made for basic acrylic welding, with of course, of plate reducers:

At the end of this blog entry, I am sharing the illustrator file of the plate reducers for you to download and send it off to your nearest laser cutting services to have them made. 

 

The file for laser cutting.

These are adobe illustrator files, it’s pretty much ready to go for laser cutting (the lines’ width, the measurements etc). 

The plate reducers with its recess. Download both files from the links below. The lines in the image above are thicker than the original file for better viewing.

These two plate inserts are meant to go on 10″x12″ plate holders.

You could modify the files to however you want. And there are two types of inserts; one would be the modern plate inserts (4×5, 5×7 & 7×9), and the other is the old plate measurements (whole plate, half plate, quarter plate and sixth plate.

All sizes for the old plate measurements were based on the traditional English size plate measurements. 

Please note the red lines are meant for cutting, and the blue lines would be for etching, to guide the lips against the aperture of the acrylic sheet.

The first file, which are the plate reducers, with 0.5mm larger on all sides to accommodate plate inserts, I would recommend using 3mm acrylic sheet.

The second file, would be for the lips for the aperture of the plate reducers, I would recommend using 1 or 2 mm acrylic sheet. Check your plate holder to see the space between where the plate rest and the darkslides.

These, plate reducers just have the texts indicating sizes of the plate as reference, add any other vector image or texts if you prefer to customise them.
