Toothed Foreplane.

Hi Stewie

Another masterpiece from your superb stable!

The finish is stunning...you sure have a lot of fine woods in your neck of the...um...woods! :mrgreen:

On the subject of "toothing" irons...Back in the days when I made guitars it was common practice to use a toothing iron to thickness very thin sheets such as rosewood backs and spruce fronts by hand and I found that the best angle for me was about 55 degrees as you have. But it still worked pretty well in an old Malloch of Perth coffin smoother body i found it in...

It's got a fine set of gnashers....

...and is made by Sanderson and Sons - Sheffield

I must admit...I originally thought their only function was to work difficult grain and it was only later when I had a chat to my cabinetmaker neighbour that he told me he used his for roughing the substrate prior to veneering.

Anyway...lovely plane...superb finish and attention to detail I've come to expect from you my friend. =D>

I'm late to this thread; how did you choose the bedding angle?

All the 19th and 20th C toothing planes I've seen bed at 80 to 87 degrees (i.e. very close to vertical).

BugBear

Hi bugbear. Process of elimination. I have previously built toothing planes bedded at 55, 60, & 90*. For the purpose of dressing the surface of curly grained timber IMO the 55 performed this task best of all 3. Keep in mind that the single irons I am using are tapered 3* so the actual approach angle is 52*.

Stewie;

Interesting; one might reasonably assume that they had the angle right (back in the day) by the same
empirical process, for the task they were performing.

My tentative conclusion is that you're doing a slightly different task (or different timbers, those damned eucalypts) from the
makers of the old near-vertical toothing planes. A different enough task that a different bedding
angle is optimal.

BugBear

Hi bugbear. We certainly have our fair of demanding timbers to work with here in Aust. I have always maintained great admiration of earlier traditional woodworkers for their knowledge & deep understanding of their trade. Much of the focus with my work it centred around replicating the techniques and tooling that were used back then. There are some tasks where modern machinery does make precision work a little easier, but I try and use that equipment sparingly. I find it much more enjoyable in the workshop when there's no high pitch noise and dust to contend with. Thank you for the information you forwarded me. Its an interesting read.

regards; Stewie.

I suspect that the higher angle Planes were intended for roughing up the wood surface prior to veneering. The lower angle being more suited to removing material on figured woods i.e. avoiding tear out.

I suppose people could have been slipping toothing blades (which were available separately)
into a smoother or jack with a "normal" bedding angle.

I've never found one like that though. Anyone?

Thanks Jimi. Its great to hear you found similar results with your toothing iron bedded at 55*(Middle pitch). The fined combed versions work really well. Not sure I would enjoy using the more coarse modern toothing blades that have been on the market the last few years. Too much work involved to remove the deeper grooves .

Sounds about right Mignal. Tend to think the traditional tpi of combing on these blades had some additional role to play as well.

Its quite possible bugbear. Rational thought process.

Looking at your nice clear photo I reckon that's Sanderson Bros. & Co.

The Sheffield Indexers site gives this

"Sanderson, Brothers & Co (, Merchts. Steel converters and refiners).
Address: 66 West St & shear steel manfrs, Attercliffe forge, tilt & rolling mills, in 1837.
Recorded in: Whites Directory of Sheffield & Rotherham - 1837."

Knew you could find it Prof!!!

Thanks...and thanks for the chat on the phone!

Just accepted a very good offer to purchase this toothing plane.

Now why does that not surprise me!
