Hi, name is Tim but I prefer to be called Ron. I've been slowly getting into woodworking projects since buying my first house last year. The reno's (have done a fair bit of building work in the past) have led to a liking of smaller and finer use of wood and just making stuff in general.

Recently I picked up a second hand Delta router table and have been loving it. Also got about $1500 worth of bits with it from a furniture maker who was selling up shop and moving overseas (just missed out on the 8 inch jointer I went there for, but came out with the router table, bits and 20 pipe clamps cheap as chips!).

I'm really liking working on the router table and it's made a lot of stuff simple that is a bit trickier or just more difficult to setup with my handheld router.

Welcome Ron. Once you've used a table you'll never want to be without one again. I have a floor model and a bench top one as well. I find when I am doing lots of small parts I like the bench top one better.

Welcome to the fun Ron. Table makes all the difference. You might wish to check for videos by Marc Sommerfeld on YouTube. He sells router items (good stuff), but more importantly, his videos show really good router table technique. Probably the most helpful vids of any I've seen. One fo the things that really helps in the table is to drop a half inch (12mm) rubber grommet into the collet so that your bits have a bottom without resting on the router's shaft. Otherwise you are supposed to raise the bit about 1/8th (3mm) above bottom, then cinch it tight. The grommet is easier and more consistent. Ask if you have any questions, we all love to respond.

Welcome to our saw dust pile, Ron (if that's actually your name). Please take the time to update your profile (upper right, under the Welcome ________ on this screen). We already have too many people named N/a on this forum.

Don't hesitate to ask us questions, because we love to help by providing answers, especially to new members.





The grommet is just a cushioned stop for the router bit when you insert ite into the router collet. You should never drop a router bit shank all the way into the collet and then tighten the collet without lifting the bit slightly above the stop. Tightening the collet pulls the bit in tighter against the stop and this can jam the collet, making the collet and bit nearly impossible to remove.

If you do this it's quite possible that the bit will become stuck and not come back out easily when you loosen the collet to remove the bit. You should always lift the bit up off the stop about 1/8" before tightening the collet. Using the rubber grommet in the bottom of the router collet will provide a repeatable, yet flexible stop for the router bit, that will also prevent the bit from becoming stuck when the collet is tightened.

Marc Sommerfeld pioneered this grommet idea and now sells router bits with their shaft lengths standardized so that when using one of his bit pairs like the tongue and groove bits, that the cutting portion of the bits will match if you bottom out the bit shafts against the grommet before tightening the collet. He now supplies these grommets when you buy bits from him, but you can also buy them from electronic suppliers. The grommet eliminates the need to change the router height adjustment when changing the bit if the bit is part of one of his bit pair sets. Some other bit sources are beginning to adopt this as well, but you will need to check this yourself if using router bits from any other source. I now have a grommet or an O-Ring (alternate method) in the bottom of the collet of each router that I own (12 total). It's a perfect solution for keeping the bit from becoming stuck, as well as helping to reduce the need to adjust the bit height when switching bit pairs.

Thanks charly for the detailed explanation, it makes sense! My collect actually removes from the threaded bit on the shaft, I find that easiest to change my bits. Will definitely keep in mind the bit sitting against the shaft and also get myself a grommet to try that out.

Tim's my real name and Ron's what my mates call me and what I prefer :)
