« Part 13: Mask & Prep for finish Part 14 of Mahogany Kitchen Stool Project series Part 15: Jigs for glue up »

After getting everything set up, the next step was put the finish on! I really like this step, each coat increases the gloss, depth and color.

I use a two finish process, both parts are from General Finishes. The first finish is their oil based coat.

I wipe the finish on with a piece of cheesecloth. The first coat basically soaks into the wood.

Areas where the grain is very tight, even the first coat shows a little gloss. I add more coats until the wood shows a uniform gloss. On average, it takes 5 coats to get there.

After that, I buff each face with 600 grit and 000 steel wool.

Next up is the top coat.

Since these stools will see heavy use, I wanted a heavy finish. When looking for a heavy finish, my rule is “add coats until you don’t want to add any more”. That took 4 coats. I’m pretty sure that I have a good durable finish on these parts.

After the top coats, I buffed each face with 000 steel wool and the applied a coat of paste wax and polished each face. I figure the wax will help with any clean up when I do the glue up.

I am really pleased with how the pieces look at this point. The appearance is great and the polished wax gives a really nice feel to each part.

Now I have to get ready for glue up. I have to confess that this step has caused me a great deal of pondering for the duration of this project. The main choice I have is do I glue up sub assemblies or do I glue up an entire stool at once? I am interested in your opinions on this one…

Gluing assemblies has the benefit of allowing the use of wood glues with shorter open time as well as less confusion and stress during glue up. The down side is if any assembly ends up a little out of square or twisted, it will be very difficult to correct it later on.

Gluing the entire stool is a much more complex process. I would expect to use epoxy to allow a sufficient open time. It would also require a really good fixture and clamping technique to ensure the stool is aligned.

More than up to my high expectations Steve.The finish looks top notch. I can think that the glue-up will be a challenge. I would try to determine which parts, if any, can be glued up separately without the danger of misalignment, or at least where slight misalignments might not be a significant problem.

I would also rehearse a full all at once glue-up. I can see that the pre-finishing is a big advantage in terms of clean-up and good coverage, but it may make clamping a bit difficult due to the possibility of messing up the finish, so you need a really well thought out plan.

I did have one idea that might help. Have you ever thought about using cargo straps with ratchet fasteners to clamp with? These are easy to pad where they contact the wood and the ratchet can produce a huge amount of clamping pressure. I have used them myself with excellent results and they are safer than steel clamps with regards to the finish. You might have to use angled pads to prevent slippage on angled areas.

Having seen how you work, I have no doubt you will have success with the glue-up, and I don’t think you really need advice on this, as you will figure it out yourself. I am looking forward to seeing your stools finished. I’m sure they will be very beautiful.

My Gosh.
What a project. The glue up would scare me too. Sorry I don’t have any hints.

Thanks guys!

Paul – I am really looking forward to just the dry fit where all these pieces come together.

Mike – Thanks! You are right – I will be trying several dry clamp setups before I bring out the glue. At this point, what is another 10 hours? I have been thinking strap clamps and very smooth clamping blocks – probably masonite. They will need to cover a large area and maybe need to be shaped in some cases.

Steve – At least I’m in good company ;)

Roger – Thanks! stay tuned …

I also can’t wait to see the final stools.

On similar projects in the past, I have done the clamping with about 1” wide strips that I had cut from an innertube. I have various lengths ranging from five feet to fifteen feet. The rubber innertube won’t harm the finish and the clamping strength is great. Also, there is no problem with the “clamp” slipping.

Stretch the rubber tight and wrap aroung the legs of the stool three or four times.

Thanks for the idea Ampeater! I have a few old bicycle inner tubes that would work great.

You’re on a roll Steve – keep going! Those parts are looking great! Only you can gauge the glue up process – and I’m sure you will go the right way….Enjoy.

Thanks Jeff! You’re right – I’ll figure it out after a couple of dry fits and test clamp set ups. Actually, I’m looking forward to solving the puzzle.

Thanks Lew!

I have been pretty patient letting this project take its course as time allows, but I have to admit that all these pretty parts is getting me fired up to do some assembly!

That is an absolutely beautiful finish and I have every confidence that you will accomplish the glue up with equal finesse. Can’t wait for the finished stools!
