Looking to make some
staked furniture...sawbench, stools and chairs etc... with
legs that involve tapered tenons and tapered mortises.
After some skill building, the first project will be a staked sawbench with a future eye to a staked chair. The designs are based on the readings and plans from The Anarchist's Design Book by Christopher Schwarz. |
||
|
The tapered mortises will be made with a pilot hole (minimum of 7/16 inch) drilled on the Nova drill press...angled using the shop built drill press table angle jig. |
 |
|
| The pilot hole may also be made
with hand brace and augers...I plan to try the hand cut pilot
holes... I have 1/2" and 5/8" Wood Owl 7.5 inch Ultra Smooth Tri-Cut augers on order. |
 |
|
|
Then a hand bored tapered hole
will be made using the pilot hole as a guide.
The taper tool will be the Veritas
Pro Taper Reamer.

| The reamer is
set at 12.8° and is the complement of the Veritas Tapered Tenon Cutters |

|
| Sharpening the tenon cutters. According to Manual... The high-carbon steel blade is supplied with a 30° bevel. As supplied, the cutting edge is adequate for rough work in most woods; however, accuracy and surface finish will be improved with additional sharpening. Start by lapping the back of the blade and then proceed to honing the bevel. A 1° to 2° micro-bevel honed on the final edge will strengthen the edge and reduce your sharpening time. |
The backs were no where near
flat...image shows two OEM blades.
The 30° bevel was quite striated...the work honing had been rough...  |
|
| This is the striated bevel... |

| This is the honed bevel... |  |

First use of tools: Used Veritas taper cutter 5/8" on an oak 1-inch dowel... |
 |
|
| First tapered tenon... |
 |
|
| I drilled a through 1/2 inch
pilot hole with a brad bit on the Nova DP...into a 1.75 inch
thick CTD slab of maple. Then ran the Veritas 5/8 inch pro taper reamer into the pilot hole using a hand brace. This was all at 90 degrees. |
 |
|
| Rough finished tapered tenon and
tapered mortise... |
 |
|
| Tapered tenon in tapered mortise... |  |
|
| After reading up on adjustments, etc. I re-tapered the
tenon with a 1/2' unit with a sharpened blade. I started the taper holding the unit and twirling the cutter like sharpening a pencil. Much better cutting action with sharpened blade. |
 |
|
| Then I placed the cutter in a vise and tried it that way...worked well |  |
|
| The tapered tenon... |  |
|
| Friction fit was so tight that it held the block easily |  |
|
| At the skinny end...the show end the 1/2" hole-tenon connection left a gap... |  |
|
| Checked for square...pretty close in left-right plane... ...but it was off by about 5° in near-far plane. |
 |
|
| Tried again with a new 1/2" drilled pilot hole and reamed a
new conical hole...trying to pay careful attention to square in
the world, but... ...gap still there, off square still there, re-tapered the tenon...still there. |
