Stefan Leon Kelly -> Rosette tile carriage (Sep. 29 2019 2:41:33)

I came up with this jig to do away with the need to chisel a taper on either side of each individual Rosette tile. You load a Rosette log into the jig, fix it in place with the bolts, align the log by sight from either end to make sure the side of the log protrudes evenly from the jig along the length, run it along the fence & past the table saw blade, turn the log around & repeat for the other side. The angle needed for the tile angles is set into the wedges beneath the “log platform”. There is a strip of abrasive along the base of the platform to grip the log. Once you have tapered the entire log you can saw off the individual tiles afterwards.

Cool jig and even cooler saw! I’ve wanted one of those for years.

You wouldn’t happen to do wooden ship modelling as well, would you? I think the saw was originally developed for that world.




Stefan Leon Kelly -> RE: Rosette tile carriage (Sep. 29 2019 7:15:07)

Ha ha! Well spotted, you’re right it is a cool saw & no I’ve never built a model ship before. It’s unusually well-engineered, precise enough for very fine rosette work & not a spot of plastic in sight! You wouldn’t be disappointed if you bought one, its a fine saw.




estebanana -> RE: Rosette tile carriage (Sep. 29 2019 16:29:19)

Cool jig, but I can do it in 2 minutes or less with a piece of paper, a compass, a bench hook and a block plane. Which are always on my table. Maybe a straight edge too. Once you use a compass to draw a circle ⭕️ and locate the tile in the center of the rosette you can radiate lines from the center to intersect the outside of the tile edges. When you see the drawing you can pretty quickly hit it by eye with a plane.

But don’t mind me, I shouldn’t even be here. It makes my limbic brain spasm and my eyes retract into my head like a feeding shark.

Pshawww....that’s nothing, man. I just scrape them into shape with the same broken beer bottle I used for dry shaving that morning. 30 seconds, tops!

But I’d sure love to have one of those saws.

After which you have your breakfast of a bowl of razor blades and bull's blood.

I came darned close to meeting the elusive target of 30s for both dry shave *and* stick taper, combined, but had to back away from it a bit. Taper was OK, but I was getting too many comments about my face.




Stefan Leon Kelly -> RE: Rosette tile carriage (Sep. 29 2019 20:50:43)

That’s an interesting idea, I would have never thought to use a plane, I think my tiles would crumble if I was to try that. I used a similar method once, sighting it up with a diagram only I used a chisel, it took me a lot longer than 2 mins tapering all the tiles individually though, but I am a slow worker. I don’t make enough use of my shards but I do use the bottom of the bottle to magnify the tiles. I too steer clear of bulls blood running up to this painstaking feat, your right to leave it until afterwards as a rewarding treat.

I think Stephen means run the plane longitudinally along the side of the log before cutting it into mosaic tiles. It shouldn’t crumble. If you use a shooting board you can angle the plane iron to get the desired taper. Another method, if you have a plane you don’t mind doing this with, is to clamp the plane upside down at the bench with a slightly angled blade. Dragging the stick longitudinally over the blade will establish some taper, which will increase in angle with each subsequent swipe. Then you can sneak up on the desired taper.

Yes, like a proud Masai warrior drinking the blood of his cows he replenishes his bodies salt.




estebanana -> RE: Rosette tile carriage (Sep. 30 2019 0:10:27)

Yeah pretty much Rob. Jigs are pork mostly.

A lot of non essential to tools are created on account of not understanding the full breadth of usage of the existing tools.




RobF -> RE: Rosette tile carriage (Sep. 30 2019 15:29:31)

Arrrrrrgggghhhhh!!!!

That may be the sound the proud warrior makes as he runs into battle, but it’s also the sound I make when I cut myself dry shaving in the morning. The bull’s blood is simply consumed to replenish the loss of my own.




Stefan Leon Kelly -> RE: Rosette tile carriage (Sep. 30 2019 15:52:21)

Bulls blood to one side for a mo!, books I had read suggested trimming each tile individually so I assumed that was what some people were doing so I suggested it as a possible alternative to that. It was planing the log longitudinally & matching it to a diagram first that lead to this jig, not ignorance of it, I misunderstood your post. I didn’t like tapering the logs with a plane because imperceptible errors would mount up & send the tiles off course, I could just nudge it back on track with a chisel but I thought I would eliminate the variables by taking advantage of the precision of my table saw & fence (sorry to rub it in Rob), now it tracks perfectly. It doesn’t take absolute necessity to feel inspired to create a jig, I actually look for an excuse to for the love of it & see it as a creative pursuit in & of itself.

Another thing I like about that saw is the affordability of the blades. If I add up what I’ve spent on specialized thin kerf blades for my old Rockwell/Beaver table saw I could have almost bought the Model Machines saw with the savings. And I still don’t have a 1mm blade!




Stefan Leon Kelly -> RE: Rosette tile carriage (Sep. 30 2019 16:51:07)

True enough, they are very affordable, less so for me when ordering them from the States with import duty etc though.




estebanana -> RE: Rosette tile carriage (Sep. 30 2019 17:26:45)

Yeah I suppose. It’s more German than German. I just don’t understand making jigs for invented problems. I never reached the conclusion that this was a problem, because I plane the tile loaf a bit and tiles fit.
When I read David Pye’s book I was already quite biased against ‘workmanship of certainly’ which in many ways I still consider the enemy of the people.

I feel like I’m a nihilist of guitar making.
