Stretcher Drilling Guide Mk III

$225.00


The Stretcher Drilling Guide Mk III allows you to easily drill holes in chair legs for stretchers, and in chair back posts for arm rests, from 4-1/2" to 12-3/4" from the bottom of the seat.

You can see it in action on our YouTube channel: https://youtu.be/vY1sGFprGj0

This Basic Kit includes the following:
Tapered Base
Threaded Rod with two jam nuts
Center-Finder
1/2" Drill extension shaft - 18" Long
1/2" Coupler - To connect the shaft to your 1/2" shank drill bit
1/2" Rod end Bearing

This 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.

Also, this Guide requires 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.

Notes:
1. The 9-1/4” threaded rod supplied with the Guide is long enough for almost all chair designs - allowing you to drill mortises from 4-1/4” to 12-3/4” off the bottom of the seat. However if you are making a bar stool, you may need a longer a threaded rod. You can simply make you own from really available 1/2-20 threaded rod, or you can purchase additional lengths pre-cut threaded rod from us. Please see the accessories product category.

2. The Drill Extension comes with a flat machined on one end of the shaft for the 1/2 coupler.

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.
