Stretcher Drilling Guide Mk III

$175.00



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 theses types of bits under our Trident line of drill bits. 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. Please add the "Machined Flat for Set-Screw" item under the accessories category if you would like a flat machined onto the shank of the the drill bit(s) if ordered with the Guide. This flat is for the set-screw of the 1/2 coupler we provide with our drill extensions (one "item" is needed for each flat you want machined).

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