I ripped six 14' x 5 3/8" wide x (planed) 2" thick African mahogany into ~4mm thick strips using a Freud Diablo D1040W 10-1/4" blade with a .063"kerf. (VERY little waste with that 1/16" kerf). I made a pass, then flipped end-to-end and did it again. In a couple of hours I had all my planking. Marked all the lumber for book matching the decks (left and right). I set up my table saw quite accurately so 90 degrees WAS 90 degrees. That way I was able to get 6 planks from each board.

Another good suggestion. Thanks. Did both of you just use the mahogany for the entire deck and stain it different colors?
Also, I have read a little in the forum about this, but even though the instructions call for encapsulating the deck boards with a couple of coats of epoxy followed by UV varnishes, did you do this? It seems like it goes against my grain (no pun intended) to use epoxy on expensive hardwoods.

Sorry about all the questions, but now that I am back on the project finally, and looking at the beautiful boats you all have done, would like mine to look as good if possible.

I HAD that exact same Rikon, sweet machine, sold it before I left Marietta still in the box for 900 bucks...dang I want it back!! (Only so much room in the truck!)

The epoxy protects the wood, the varnish protects the epoxy!

I put that Sh*t on everything! Something about epoxy, probably an false sense of security, but I would bet it is better to have than to have not.

Bunch of guys will chime in on this, just hang out a bit....

Good luck, and we like pics! :o :wink: :!: :P

One thing that you must never do is ask your better half to tail out for you it just does not work,learn how to do it all yourself....

Yes, it is a good saw, but have recent bad experience making xmas gifts with the Rikon drifting in some padauk so have lost my confidence! :) As stated earlier , think I set side bearings too far up on blade and ruined the set. Been off Monaco project for about a year now due to things, but back full blast, attempting to get finished by June or July. Just retired. Currently fairing and starting battens, okoume ply on order, hondouras mahog on floor for planking, needs resawn, switched to white oak for battens. Frames are hondouras . Spending time back on this great forum , learning and asking.

Probably in wrong thread, but wondering if I can emulate the wonderful finishes seen in the photos of the Monaco by so many excellant builders. If these finishes (piano looking finish) can be obtained still after applying a coat or two of epoxy?

And no, my wife won't tail either, so learned to make one man jigs and supports. :roll:

BTW, a previous old post I made suggested ebony for strips on deck. I just had a piece in my hand at the yard this morning. Gold would be cheaper! He charged me for just the ebony dust I wiped off the piece. Someone earlier suggested wenge, which also looks good. Still thinking .

Have the pc blade on order that Billy c recommended .

Thanks to all .

fredt you will achieve those type finishes faster by encapsulating the decks with epoxy rather than building up varnish from the start

You will get that Rikon on track I am sure. Generally it is not the saw, it is the set-up of the saw. That is critical. And don't expect ANY bandsaw to saw evenly with a fence locked in a location parallel to the blade orientation....they will all drift differently with each different blade you put on, so you have to run those test pieces each time.

Thanks SS, will be receiving new blade by Friday , going to spend lots of time setting up. The fence is a good point. I am making a 8" high and will set it up according to what the new blade drift is.

If I recall, I cut my last veneer close to the fence, instead of on the outside of the piece, may have also been part of the problem. I may also be over tensioning. I've watched people cut 1/16" veneer with this saw, all I need is 5/16" at this point. I will be doing lots of testing prior to sawing the mahogany .

...yes, the PC series
Billy C, got the new band saw blade in , 2/3 tpi as you recommended. Really worked great, and I spent a little more time relearning my saw and proper set up. Was able to easily slice 1/8" and 3/16" practice veneers.

Thanks for the tip.

I love wenge and use it on my guitars all the time. Depending on how you cut it, can show a beautiful straight grain, or an even more beautiful wild grain. It bends well with heat and proper backing support, but is a very splintery wood. My only concern, much like padauk (which I also use and love on my guitars) is how porous the wood is. From a finishing standpoint, both woods take an extra application or two of pore filling to get that glass finish. I like to use silica in my epoxy for a clear-looking pore fill, and usually take 3-4 applications on my guitars to get all of them filled on both Padauk and Wenge. Pores that deep will show discoloration if you don't adequately mix your epoxy....will show white or grey silica unless lightly and/or perfectly mixed. If you use a tinted solid, say using a dark or black tinted paste (purchased or hand made using wood flour), it will almost look like ebony when sanded back to the wood. Otherwise, love the stuff.....Have a wenge jumbo guitar ready to bend the sides.

This is a case where the saw is more able than the operator! :roll:

:lol: I have 40 plus years using wood working equipment and I still make mistakes but it boils down to practice just be careful machines have no mercy they will eat even the pros if they get careless. I know this first hand I am missing the tip of one finger to a joiner :roll: :( 8)
Don't be afraid to attempt anything. You might surprise your self in the attempt.

After the service in 69, I embarked in the lumber industry . Old school lumber yards , old school mills in each lumber yard. Most of the workers were known by their nicknames, like 1 finger, 3 1/2 finger, etc. OHSA started about then, and attempted to make us put guards on everything, which caused more accidents!

I am fortunate to have a few nice tools collected during my construction of my home. that was 5 years ago and I am attempting to refamiliarize myself with them, hence my statement "my tools are better than the operator" :oops:

My Monaco project, a once in a lifetime dream for this old man, is causing me to relearn, which ain't easy :lol: Ready to start first plywood lam this week.

You are very right. I need to keep practicing on some of this equipment, especially the bandsaw to get my mahogany planks started soon.

If you have worked for that long around woodworking machinery, and only have that tip gone, you qualify to be a real expert, and one who respects the equipment, but not afraid of it. That's a beautiful thing.

Thanks
