Popular Post difalkner Posted February 26, 2017 Popular Post Report Share Posted February 26, 2017 I just started this project but thought I'd post a couple of photos before it is finished. This will be a round end grain Black Walnut cutting board style Lazy Susan about 18" diameter and 1.5" thick. I cut and milled all the stock Friday and Saturday we glued up the sticks. Before we started glueing I drew a layout in CorelDraw so I wouldn't waste any precious Walnut. This is the board for the project - 4/4 rough, 12" wide, a bit over 8' long. The specification is for all heartwood so the little bit of sapwood on this board will go on other cutting boards or projects - Here's the layout - All the pieces glued up for the night. We used Titebond III even though it isn't a cutting board, just a Lazy Susan, mainly for the longer open working time. That's a lot of sticks to glue up if they start tacking right away! And I had an opportunity to take an artsy shot prior to glueing the sticks together and I don't like to pass those up - I probably won't have time today - busy day at church - but next I'll take these out of the clamps, surface lightly on the drum sander, then cut into strips about 1.6875" which should allow me a nice 1.5" finished thickness. More later! David 5 Quote Link to comment Share on other sites More sharing options...
Popular Post difalkner Posted February 26, 2017 Author Popular Post Report Share Posted February 26, 2017 Had a few minutes before heading back to church and cut the boards into strips. We just set them sort of in order how they came off the saw but we'll probably move them around, flip some 180°, etc. Also, I decided to cut them first and then run through the drum sander. It's a lot easier handling a bunch of small strips than trying to get a really large panel flat. We might get a chance to sand them after church tonight. 3 Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted February 26, 2017 Report Share Posted February 26, 2017 That's gunna look nice with the pieces all switched around. Can you explain cutting the strips then drum sanding them? In all the boards I've made, walking pieces during glue up is what needs flattened. If your blank was good and you cross cut them at the same size at 90°, they should already be all the same sizes. What am I missing? Quote Link to comment Share on other sites More sharing options...

If your blank was good and you cross cut them at the same size at 90°, they should already be all the same sizes. What am I missing? In the first glue up a few strips shifted slightly and need sanding. Additionally, in a board and glue up of this size it is almost inevitable that there will be a slight amount of bowing, even if only 1/64". I figured to get a 19" x 16" board completely flat I would lose as much as 1/16" of thickness and I don't want to give that up. That much loss on the big board becomes 1/16" loss on each strip when it is cut, which in this case is 9 strips so that would be a 9/16" loss overall. Make sense? This is the first time I've done it this way but also the first time I've had dimensions where I couldn't run it through my small planer (old DeWalt - 12.5"?? not sure how wide it is). If the glue up had gong perfectly with no shifting and no bow at all I would have run it through the drum sander - SuperMax 19-38. As it is I'll run the small strips through until they're clean, making certain they're all very close to the same thickness, and then glue it up. Here's the shift I mentioned; it is small but coupled with a tiny amount of bow this could amount to a significant loss in thickness.

Now that makes sense. The blank wasn't flattened before crosscutting. Quote Link to comment Share on other sites More sharing options...
difalkner Posted February 27, 2017 Author Report Share Posted February 27, 2017 Correct. I normally do that but my planer isn't wide enough to handle these and I didn't want to just sand it down to flat so I'm dealing with it this way. I need a bigger planer or to make smaller boards - LOL! Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted February 27, 2017 Report Share Posted February 27, 2017 Or use the open end drum sander. There's a reason they call it an abrasive thicknesses. Quote Link to comment Share on other sites More sharing options...
difalkner Posted February 27, 2017 Author Report Share Posted February 27, 2017 Yep, still didn't want to do that. Part of the reason is the coarsest grit I have on hand is 100. The other part is I'm ok doing it this way... Quote Link to comment Share on other sites More sharing options...
Coop Posted February 27, 2017 Report Share Posted February 27, 2017 I've never tried it but hearsay is that you don't want to run endgrain boards, large or small, thru your planer! 1 Quote Link to comment Share on other sites More sharing options...

You can get away with it if you use sacrificial ends and have a spiral/helical head planer. But I don't have one of those. Quote Link to comment Share on other sites More sharing options...

Popular Post difalkner Posted March 17, 2017 Author Popular Post Report Share Posted March 17, 2017 Well, I sort of forgot I started this thread so here's the update - it's finished!! I used the CNC to cut the profile and a 1/32" recess for the outer race of the Lazy Susan bearing. I could have just used some thin washers under the inner race but it was easy to just cut the recess for the outer race. Having a wide drum sander is really nice but the finest grit I have is 120 and that leaves noticeable straight line scratches. These scratches take a LONG time to get out with my DeWalt ROS so I broke out my 'old iron', an air operated 1/3 sheet orbital. This will seriously hog some material. A side note on the dust is that I used the downdraft sanding box we just built and even though the 1/3 sheet sander doesn't have any dust collection but creates a lot of dust, the downdraft box caught almost all of the dust this sander was kicking up and that was pretty nice. The last cutting boards we did were only about 12" x 12" and took a solid hour of sanding with 120 grit on the ROS with about 5 changes of sanding pads. The 1/3 sheet sander with 120 grit did the entire top in 5 minutes - a significant difference, for sure. I sanded about 2 minutes, changed paper although the first sheet was probably ok, and then let my compressor catch up. After a short compressor rest I sanded the top again and then a quick pass on the underside. I followed up with the ROS for a few minutes and then hand sanded for a few minutes with 220 grit and it was glassy smooth. It has a couple of coats of mineral oil followed by our mixture of Beeswax and mineral oil and then hand polished. On the CNC (dust shoe removed so I could video and that will be posted soon) - Straight line scratches - The two sanders - In process - Underside with bearing - Finished top side - The 'glamour' shot - LOL! When I finish the video I'll post it here - enjoy! David 4 Quote Link to comment Share on other sites More sharing options...
..Kev Posted March 17, 2017 Report Share Posted March 17, 2017 That turned out very cool! Just curious if you had any thoughts of recessing the bearing in the bottom? Regardless, looks great as is! Also, where did you get your bearing from? I like that a lot better than the ones I've been picking up! Quote Link to comment Share on other sites More sharing options...
difalkner Posted March 17, 2017 Author Report Share Posted March 17, 2017 Thanks! Briefly considered recessing the bearing but as it is there's only about 1/2" clearance; much less and it's hard to get your fingers under it. I recessed for the outer race because it was slightly proud of the inner race but the friend I'm making this for said to leave it like it is. The next one I do might be recessed further - who knows...? It came from Amazon, 12" Low profile Lazy Susan bearing David Quote Link to comment Share on other sites More sharing options...
Popular Post difalkner Posted March 19, 2017 Author Popular Post Report Share Posted March 19, 2017 It occurs to me that y'all might be interested in my setup for some of the photos so here's one that I didn't post but I'll be using it on Etsy soon. There are other photographers here and you guys will enjoy this and probably be able to pick holes in my setup but it works ok for me. When my son moved out a couple of months ago we set his old room up as a studio setting, albeit a low budget and simple one, but I can take an item in there, place it on the table, turn the lights on and have good control over lighting for just about any item. Those of you that do photography may see this often but if you're not into photography this may be new to you. For the Lazy Susan I decided to take one shot with it set on our table so I moved the lights to the dining area - that's what I'll show you below. Ignore the vacuum cleaner, guitar, and junk beside the table - temporary storage while we're cleaning out a spot elsewhere - what can I say... it's a lived in house! LOL! Here's the shot straight off the camera, no post editing - not bad but could use some help - Here's the final shot - And here's the setup for the shot above - For the photographers the camera is a Panasonic Lumix DMC-FZ200, Leica lens, settings are ISO 100, f 2.8, 1/4 second, -0.33 eV, RAW 4000 x 3000 x 48b. The editor is ACDSee Ultimate and tools used were 20% dehaze, auto contrast and color 15%, exposure moved another -0.15 eV, and fill light bumped a few points, then resized to 1080 x 810 and saved as a jpg file.

wdwerker Posted March 19, 2017 Report Share Posted March 19, 2017 Then when you know what they mean you will have to buy a small fortune worth of photo gear. Sounds like a rabbit hole similar to woodworking ! 1 Quote Link to comment Share on other sites More sharing options...
difalkner Posted March 19, 2017 Author Report Share Posted March 19, 2017 LOL! Yes, it can suck some money, for sure. And very little tangible to show for it like you get in woodworking. I've been doing photography since about 1973 and have some really neat landscape shots but nobody asks to see my photos - they do ask to see what I've built in the shop, though. Btw, don't assume I know what all that stuff is; I was just trying to impress y'all. Quote Link to comment Share on other sites More sharing options...

difalkner Posted March 30, 2017 Author Report Share Posted March 30, 2017 Amazon - 300mm Lazy Susan bearing. Yes, it's fairly smooth and quiet, seems like it will work well over time. David Quote Link to comment Share on other sites More sharing options...
