The Spindle Drilling Guide allows you to easily drill spindle mortises in chair bow and arms. The "offset" design allows you to drill centered spindle mortises in arms up to 6" wide, and from 5" to 30" above the seat.
You can also use the Spindle Drilling Guide to drill blind spindle mortises from underneath, like for a crest rail and for other non-chairmaking operations; such as casework, stairs, etc.
You can see it in action on my YouTube channel https://www.youtube.com/user/thetexwood, or my IG feed/IGTV at "barton.kyle".
The Spindle Drilling Guide includes the Spindle Drilling Guide and one drill bushing of your choice. Please let me know if you need custom dimensions for a particular use case.
Please note: If you add any accessories for the Spindle Drilling Guide with your order (e.g, additional Drill Bushings, Pointer, or Stiletto Drill Bits), I will refund to you any overages on the shipping charges.
