Combo Kit - Stretcher and Seat Drilling Guides

$450.00



This Combo Kit includes both the Stretcher Drilling Guide Mk III and the Seat Drilling Guide Mk II. These Guides allow you to easily drill holes in chair legs for stretchers, and in chair back posts for arm rests (from 4-1/2" to 12-1/4" from the bottom of the seat); and also easily drill holes in chair seat blanks for leg, arm post and spindle mortises.

You can see them in action on our YouTube channel: https://youtu.be/MiXCBSvGQ7k & https://youtu.be/5BiI3kRUz6g

These Guides require a drill capable of accepting 1/2" shank drill bits; and a 1/2" shank brad-point bit with a long center-brad to work correctly for acute angles. We sell these type of drill bits under our Trident Drill Bit line (link: https://bbcustomtools.com/listing/733888113/trident-drill-bit). This Guide should work fine if you are already using these types of "chairmaking" bits with a 1/2" shank.

The Stretcher Drilling Guide Mk III includes the following:
Tapered Base with Threaded Rod and 1/2" Rod End Bearing
Center-Finder
1/2" Drill Extension - 18" Long

The Seat Drilling Guide includes the following:
Seat Drilling Guide Mk II with Threaded Rod and 1/2" Rod End Bearing
Set-Up Block/Angle Gauge
1/2" Drill extension shaft - 10" Long

You can also upgrade to the 10" 12-Point Drill Extension for the Seat Drilling Guide - very useful for reaming with the Guide. What sets the 12-Point Drill Extension apart from our standard 10" drill extension is the 1/4” 12-point bolt at the end of the extension. That provides increased torque and purchase, making it easier to ream with a socket adapter in your drill—especially useful for reaming in hardwood seat blanks. More importantly, it allows you to use a 1/4” socket wrench or box wrench for hand-reaming with Seat Drilling Guide, so you can sneak up on that perfect fit.

Notes:
1. The Stretcher Drilling Guide is made for a 6 degree reamed holes. Please let us know if you use a different reamer (Lee Valley Reamer, 11 degree reamer, etc.) We should be able to accommodate you.

2. The Drill Extension comes with a flat machined on one end of the shaft for the 1/2 coupler. Drill bit is not included.

3. If you want to use the Stretcher Guide in smaller diameter mortises that are reamed after drilling a 1/2" hole; please check out the "Arm Post Base for the Stretcher Drilling Guide" under the Accessories category.
