Big problems with cutting HDPE can you help?

[Lee Roberts]

Did you ever get to the bottom of this Nathan ?

[Nathan_Partington]

yes,

I purchased a speacial tool from Trend, and made a jig out of 25mm mdf to allow the router bit to cut both the top and bottom edges at the same time. it took a lot of time to get it right but the customer was happy in the end.

also ive been using 10mm diameter neoprene to seal the jigs off. Does anyone have an alternative to this as it it quite expensive.
