« Part 12: The Rails Part 13 of Split Roubo Workbench series Part 14: The Chop - updated »

Marc recommends a hard species of wood for the parallel guide. A hard maple board would have been nice but i don’t have any. I do have several pieces of jatoba that I bought from a dude with a trailer of cut offs at a local WW show. I thought about cherry but it is about the same hardness as soft maple on the Janka scale. Plus, the jatoba matches american cherry quite nicely.

Here is a piece that is damn near the final dimension. But this stuff is HARD.

I took it down with the scrub. With this wood I took baby bites.

Then I tried to take down the high spots with the Jack. I don’t have pic but my winding sticks demonstrated twist. I finally got it flat. I struggled here.

I further flattened with the jointer but re-introduced some twist. Once I got thought that out I gave up on removing a 1/4” for final thickness. So, off to the bandsaw. FYI, the woodslicer blades for Highland Woodworking are quite impressive.

Then flattened with the jointer

After cutting to final dimension, I cut the tenon at the table saw making sure to leave it fat. That will trimmed with a block at the time of fitting it in the tenon.

The resaw cut-off made a nice template for the holes. Then it was time to make a toast to my LJ buddies.

Concerning the end of the parallel guide. The plan comes with a template for a double ogee. like this…..

Its nice but this bench doesn’t speak double ogee to me. As a design element, it seems out of place. I see something angular and simple but haven’t committed yet.

Man you are burning the midnight oil. I tore up two perfectly fresh irons on that stuff. It is HARD!. The Parallel Guide will last forever. And the template you made will to.
Nice update.

The alcohol is becoming your signature product placement. The bench is going to be awesome. Well done.

Jatoba is one of the harder woods I’ve worked. A sharp plane will do it, but it has a severe dulling effect.

Yea Shane, I am going to tone that down. That is not what i am about. I don’t drink very often but it seems that when I do, my woodworking “stuff” seems so cool. I am inspired to take a picture. Plus, a lot of my beer pics are the same ones that have been posted before.

I am not saying you are a lush…more that maybe an advertising/promo deal could be in the works. Maybe some commision checks or at least free product.

Oh, that would be awesome. With the hand cases that I do I could definitely give testimony for SawStop but a microbrew sponsor… cool is that?

please drink responsibly. (which means only if you have a sawstop). :-)

Is that glass a 1/4 full, or 3/4 empty?

Nice job on the guide. I never worked with jatoba. It looks like a nice tote material.

If anyone is not familiar with the Janka Hardness scale here is a nice introduction and graph.

Don, it would make a great tote material. It looks a lot like american cherry except a more open, varied grain pattern and the color is a tad more golden.

I love the new tagline, Lysdexic!

Appreciate the resaw blade advice and the discussion of jatoba. That sure looks alot like the stuff I used for a vice chop months ago. Cherry looking, very wild ‘grain’ and harder than all get out…nice guide, I agree the dbl ogee wouldn’t fit. Almost there!

Nice to see all the progress lately Scott, I bet your loving being able to use that wagon vise already.

That is some brutal stock prep. But I bet the fine shavings came easy.

Actually Ryan, nothing about this board was easy. If you look at the first pics, I would think that it would be easy to use a jointer and, using the already flat surface, plane out the saw marks. I tried that and it was taking forever. That is when I switched to the scrub. that removed the material but introduced twist. I knid of chased my tail from there.

I need much more practice flattening with hand planes.
