router newbie, question about router bit wanting to wander
i was routing 3 five inch slots in HDPE. the slots are 3/4″ wide, and i was using a 1/2″ straight cutting router bit. i was using a clamped guide, and running the router against the guide surface. the slots required 2 passes, and i had to move guide for second cut. first and second slot cuts went fine. on 3rd, the first cut went fine, but when i went back to finish the 2nd cut which only was taking about 1/4″, the router jumped ahead, and away from the guide.
Any ideas why this was happening?
it started to do this again, on 2nd try, so i stopped and put another guide in, to hold the router in place from both sides. this worked.
this is the first time i have worked with HDPE. the first router cuts went very well, just like wood. i was wondering if maybe i needed to increase speed of router for the hdpe ?
thx in advance
