I made some more progress on the rack build and it continues to come along nicely. Since the last update I got to use my big fancy Festool router and my new big fancy 3/4 inch flush cutting bit to trim the excess veneer. They were both a bit of a splurge purchase for me before, so it was nice use them and have them work beautifully. Nice tools are things of beauty. I pulled the panels out into my driveway to try to avoid getting dust all over my car build and was expecting the wind to blow all the dust away overnight. What I failed to remember was there basically adhesive on one side of the dust so it all just sat on my driveway for a couple days until I admitted my defeat and went and swept it up.
One I had the panels veneer trimmed to size, I was free too start cutting all the mortise that will hold everything together. I want the panels to be flush along the bottom with the bottom of the walnut frame and have a small recess down from the frame to the panel along the top of each shelf. This turned into a really fun problem to figure out exactly how I needed to mark and cut everything so I could be consistent and get everything lined up. Yet again, I found out this was going to be way more complicated than I expected.
To get the bottom of the shelfs line up with the frame even though they were different each a different thickness, I needed to reference off the bottom of both for my mortise cuts. I originally thought I could line the shelves up with the frame and mark them both together and cut to match but learned I needed to transfer the lines to the other side of the frame and be very mindful of what side was going where when everything was flipped the right direction.
My wife had bought me this awesome saddle square for Christmas that really came in handy for transferring all these lines around to the other side of the wood. It was one of those things that the right tool makes all the difference and while this seem simple and straightforward, I had to transfer a couple hundred marks to the opposite sides of the boards and even with the right tool this took probably around four hours to think through fully and get everything marked. I had to keep in mind where everything would be when the panels were flipped over and keep everything in line and organized. Even with all the planning, I got a panel wrong and needed to put some extra cuts in the walnut to get things lined up. I probably should not have said anything about it. I filled the holes and each was completely covered up in the joint so nobody would ever know, but I think people should share their woodworking mistakes so others don’t feel a need to be perfect themselves so I will admit my error.
Once I got everything marked I had to setup various temporary jigs to allow me to be as repeatable as possible on the frame. Those cuts went smoothly and dry fit came together nicely. I seem to have forgotten to take pictures of most of the jigs but it was not anything too fancy.
First dry fit of the frame pieces.
I lost count of the mortises I cut, but I"m pretty sure I topped 250 and didn’t look back. Took some time to pull off but they did come out well after I fixed the error I mentioned above from screwing up the rotation of a panel when flipped. None of my mistakes will be visible, so who really cares, at least that is what I am trying to convince myself. However, once I got them all cut and went to do dry fits, I realized despite me trying to simplify this by making it two chunks that I will later fit together, this is still going to be a nightmare to glue up. I did figure out the order of operations, it is just going to be very difficult to pull off as quickly as I will need while the glue sets up. In fact, I think I might use epoxy instead of glue to give myself a longer setup time to work. I really don’t want this thing to fight me long enough that the glue starts to setup before I get it fully together.
The plan is to start with one panel and one side of the frame, then rotate the peice onto the frame once they are together and drop the second shelf into position like you see below.
I found it somewhat difficult to try and line up the shelf but it was doable by myself with a little luck. The shelf with the side frame pieces that will need to be attached when the shelf is put in place wights just over 50 lbs, and are too bulky for me to hold at eye level, so I end up lining it up as best I can from a weird angle and then try to lower it down onto the tendons I have sticking up from the frame. Once I have the two shelves in place, I have to get the other frame piece to fit over each of those 21 tenons sticking up and slide down into place. One of the two went together surprisingly easily, but the other took some persuasion and choice words. 21 tenons is probably the most I have tried to line up at once and I am a little impressed with myself that it will go together.
I did 3D print some dry fit dominos that you can spot a few off in the photo above. They were actually fantastic for dry fitting and move a little easier than the wood, but I have only printed off about 25 so far in the size I was using for this project. I plan to print some more as I did prefer working with the 3D printed ones than wood for dry fitting.
Below are some shots of the very first dry fit. I’m going to make a few adjustments to get everything perfect as there are a couple things that are just a little off. My wife did not spot them so nothing too bad but I think I am tweak a few things and get things just right with some effort.
The shelf in the back will be the top and I have 8.5 inch pieces that will go between the two frames. This puts the walnut burl as the very top and the bottom shelves with the two maple shelves in the middle.
Here is a bit better shot of the top. Though the finish is going to bring the color out a lot I still think it looks great even unfinished. I really think that is an exceptional chunk of burl and am happy I chose to cut out the best parts of the sheet instead of trying to minimize the amount of scrap. It cost me but it came out beautifully.
Below is a better shot of the recess down to each panel. I’m not sure it comes through well in the photo but the maple makes it a bit easier to spot. I had been thinking of doing a chamfer/bevel down to the shelf but my wife thinks I should leave it how it is and likes the consistent hard edge. I’m not sure. I was thinking I would need to do the chamfer to make the recess look intentional, but now that it is there, it already looks intentional and has a decent ratio to it. It might be easier to judge from the earlier photo with both frames on my workbench laying in their normal orientation. Any of you willing to share your opinion?
I also made a bit of progress on the speaker stands but I still have not fallen in love with them. I used the router table for a heavy chamfer of each post corner. The chamfer will be better for sound reflections, but I’m not sure I like the look. It did not really turn out how I was picturing and I’m trying to decide if I want cut even more off or accept it. If I accept it, I just need to sand everything then glue to together and add finish.
In additon, I also cut up a bunch of cedar I had to start building six sound absorption panels. They will be 30 inches wide by 41 inches high and 9 inches deep. I think I might start a separate build thread for them though.
Lastly, we got the laser fixed and I went back to working on a piece of art for my uncle. When I went to see a Grateful Dead cover band with him recently, he mentioned that “Wharf Rat” had hit home and ment more to him recently as he has become a therapist helping kids rebuild their lives. So, I pulled what I hope will be a meaningful lyric for him and added it to the piece I have been working on. I still need to clean it up, but here’s what I was able to get right off the laser. I’m going to use a really nice piece of ambrosia maple with a ton of variation for a frame. The ambrosia variation will work really well with miters to show the grain wrap that will go around the top three sides and I will leave the bottom with the broken board open and unframed. I think it will turn out great.
