Thanks Bodgers. Much appreciated. Was wondering if I could be missing something with my inexperience. Appears not though I'm still slightly bemused by it. The margins must have been extreme!
It
must be the collet not being tight enough. I read the other day in Alan Holtman's Trend 'Complete Routing' about not over-tightening. Perhaps I was a little to easy on the hand tight then half a spanner turn advice! Can't see it being the collet or the Wealden bit which leaves user error.
It's clearly worked out a few mm when I just went out too check. But I can't budge it by hand it's not
that loose. Will hit the spanners with a club hammer next time. (Joke!
)
You can lock off the depth stop screw on that Makita model so I don't think it was that.
Not the end of the world, just a tedious job. The bit is a longer shanked 12mm straight flute to accommodate the sled height. Bit leery of cutting much more than 3mm in one pass. Will have to do the other half of the bench to height then redo it all again to finish. It's thick enough to take it but a 12mm bit on a 6 foot by 2 1/2 odd foot surface is a bit jarry! Still have to sand it after. :roll:
I looked at the dedicated bits for flattening stock but they were £30+ and with Christmas due in a minute, could not justify it however I kidded myself.
Think I'll do it with a plane next time. Thought I could probably get it flatter this first time with a sled.
Thanks again Bodgers.
Appreciate you taking the time fella,
Chris
