There are times when I need to lock the trigger on my drill. Growing up I used my dads drill and it had this feature. Many drills do not have a lock on the trigger or at least I haven't seen any. Maybe it is too dangerous, like the drill can take off on you. I made mine very safe and can be taken off easily and in an instant.
For this project I will use some leftover hardwood flooring. I think oak and Brazilian cherry look good together. I cleaned up some pieces on the table saw. I always cut a little bit extra in case I make a mistake.
The pieces are glued with Titebond and clamped over night. I now can take some measurements of the drill handle. Of course this will be different from drill to drill.
I used a forstner bit to drill out the area that fits around the drill handle. The piece is placed in a small clamp and with the drill press I drill a hole, this will be for the bolt.
A router and a round over bit is used to soften the edges, this will also help the jig fit the drill. With my extra piece of hardwood I use a hole-saw and make a small wheel. I then add a nut and bolt and screw it into the block and it is ready to go.
