dodge78 90 #1 Posted August 28, 2022 I am working on a cart that made if pipe. I want to use some red oak as sides but have the wood routed with a round bit so it goes around the pipe. I am trying to find an easy way and safe to get this done. I thought about making a tall fence to hold it against to do the end grain but not sure if that is the best way to do it. Any suggestions?

EB-80/8inPA 1,641 #2 Posted August 28, 2022 That detail looks like it could turn into a puzzle. Once you did manage to get it formed, how would it be positioned, slid in from the top? Will it clear the frame as configured? 1 Share this post Link to post Share on other sites
dodge78 90 #3 Posted August 28, 2022 Slid in from the top, there is enough flex in the pipe to get it to fit 1 Share this post Link to post Share on other sites

formariz 11,987 #5 Posted August 28, 2022 If you do not have a router bit as indicated on link by @gwest_ca , that will allow you to use board face as reference then you need a core box bit which will be available in the radius you need. You need to set up a router table with a sufficiently tall fence. Make sure hole for bit on table is exactly the bit’s diameter or when doing corners piece will “sink” into it. You can accomplish that by raising bit through table material. Take light consecutive passes until you reach desired depth. Very light passes will make it safer when doing end grain since but will not “catch” grain. 1 Share this post Link to post Share on other sites

dodge78 90 #7 Posted August 28, 2022 The board is 1 inch thick so I was going to buy a 7/8 core box bit. I like the internal bullnose bit but I do not know how well it would work on a rounded corner. If I am using 1x6 and 1x8 boards about 2 feet long, how high of a fence should I shoot for? Share this post Link to post Share on other sites
formariz 11,987 #8 Posted August 28, 2022 The higher the safer but leave enough of board exposed during run on low side so you can hold it properly. 1 Share this post Link to post Share on other sites
formariz 11,987 #9 Posted August 28, 2022 Place also a feather board or a plain board screwed or clamped to table putting slight pressure on board being machined against fence. Again very light cuts, 1/16” or less each time is the key to a smooth finish cut and one operation with no drama. 1 Share this post Link to post Share on other sites
