INTRODUCTION THE GERBIL The Gerbil is a unique machine that was originally designed as a safe and easy method of trimming out vacuum formings. Over the years it has evolved and it is now a much more versatile machine that can be used to perform a wide range of tasks. Resource Material G1 gives an overview of the different tasks that can be performed on the Gerbil.
INSTRUCTIONS STAGE 1 – TRIMMING OUT THE VACUUM FORMINGS 1. In total there are 3 acrylic formings to be trimmed, all on one sheet. The lid is the forming which has some writing embossed on it. The base insert has groves to hold the pencils in place.
INSTRUCTIONS - continued STAGE 2 – SLOTTING THE PANELS 1. Cutting slots requires using the tungsten carbide disc, combined with the extraction and guide fences. For detailed instructions refer to Resource Material G4 2. BOTH side panels need to have two slots along the length of the panels. Both slots will remain as slots right through to the end.

INSTRUCTIONS STAGE 2 – continued 12. Set the guide-fence and cut the slot as detailed in Resource Material G4. 13. Repeat step 10 for the second side panel and for the standard end panel. 14. Check the size of the slots by sliding the trimmed lid forming along it. If necessary, raise the height of the disc by ~1mm, and repeat the cut along all of the slots in order to make them wider.
INSTRUCTIONS STAGE 3 – REBATING THE END PANELS 1. Cutting rebates requires using the tungsten carbide disc, combined with the extraction and guide fences. It is carried out in two stages – first of all a slot is cut, then the workpiece is turned by 90˚ and a second slot is cut to create the rebate. For detailed instructions refer to Resource Material G4 2.
INSTRUCTIONS STAGE 4 – TRIMMING THE REDUCED END PANEL DOWN TO SIZE 1. The reduced end panel needs to be slightly shorter so that the lid of the pencil case can be slid in and out. 2. Use the slotted reduced end panel as a guide to set the height of the disc. The disc should be at the height of the existing “top”...

The Gerbil is a versatile work table, for use by students in the classroom, into which can be mounted a variety of tools for working on plastic, wood and metal. There are three models, the basic 2010, fitted with a trimming disc, the 2020, which has extra features such as a tilting table, extraction and a range of tools, and the 2030, which features a 2020 model with a purpose-built trolley.
Trimming Disc Table Top Both the 2010 and 2020 Gerbils can be used with the tungsten carbide abrasive disc to trim out vacuum formings leaving a straight edge. The following safety instructions must be observed at all times: wear safety goggles, tie back long hair and remove any loose jewellery.
A flange may be necessary, for example, to provide a surface for sticking two formings together. The cutter can also be supplied separately and fitted to the 2010 model. The flange tool consists of a cutter shielded by bearings above and below the table. The bearings serve both to hide the blade for safety and to act as a spacer controlling the width of the flange.
Design & Technology Resources The Gerbil Using the Gerbil to Cut Slots and Rebates Tungsten Carbide Disc Dust Extraction Fence Guide Fence By using the tungsten carbide abrasive disc and the guide and extraction fences on the Gerbil 2020, it is possible to cut slots and rebates in softwood. This is very useful for making wooden boxes or enclosures.
This is particularly useful for the finishing of small pieces, as this can be hazardous on a full size polisher. The mops and compound bars can also be supplied separately and fitted to the 2010 model. 1. The following safety instructions must be observed at all times: wear safety goggles, tie back long hair and remove any loose jewellery.
