Working with acrylic
The windows on my Windbreaker are shredded. I have been thinking that if I can route a flute in the edge of some .220" acrylic sheet that it might just snap into the wire window frame without the need of any fasteners.
Made a crude cutter for the router table. If I can keep the tool speed down and the material feed up it may just work without turning this into a molten mess. If anyone has some tips in working with this material please chime in. Thx

I hate machining acrylic. Its very brittle and will break/crack/melt. Is using Lexan (polycarbonate) an option? If you must use acrylic, keep the tool and workpiece clamped securely. The tool needs to be sharp, but not so much it grabs the workpiece. Not sure if what you are trying will work at all on a router table--fast RPM, no coolant, the workpiece is not clamped. Good Luck.

Thx for the input John.
I know what you are meaning about work holding. No way to hold the piece down for this operation. I'll just have to take multiple light passes and hope for the best. I read somewhere than freezing the material may help. I may have to rethink my cutter. My original thoughts wear aimed at chip evacuation.

One down. One to go. Had to really turn down the router and feed it slow. Still need to cut out for the hinges and come up with some sort of retainer clips just in case. Don't want these widows popping out at the most inopportune time.

Acrylic is brittle, be careful drilling holes near edges.
When the drill punches through, it grabs and tends to spall or bust out. When building guarding, we went to lexan (polycarbonate) as it will cut on the shear and bend in the brake as well as drill/tap without breaking. As far as edges, we rounded them with a rasp file and hit the edges quickly with the acetylene oxy torch with neutral flame, making them smooth like they were never cut and clear, giving a nice looking job. It takes a little practice to get it right, but worth the effort. ---just my experience |

Thanks George, for the words of caution and your insight on this material. I have used it to make guards, covers, and enclosures in the past. Just never did any edge work with it until now.
Did I really need to flute the edge for this? Probably not. But it will stay in place better with fewer fasteners.

That came out great! As a 30+ year auto glass guy, acrylic is a pain in the ass to work with. Randy

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
