Hi,

I am working on my workbench, and I have come across a problem. I am planning on using those hex bolts that screw into a cylindrical threaded "nut" to hold horizontal stringers to the table legs. In order to do that, I have to be able to drill down into the end grain of the stringers for the bolt.

I have access to a floor-standing drill press, but I can't see a reasonable way to orient the stringers vertically, on end, for this bore.

I began to wonder whether there is some kind of jig I could make to fix a hand electric drill in a horizontal position with a little fence along which I could feed the stringers to do this bore.

Any ideas or suggestions?

Many thanks,

George

If you know anyone close with a Shopsmith, you could hit them up for a little favor. Or go on Craigslist & find a cheap old used one for yourself. The horizontal boring feature is great…but then, I'm a Smith nut…actually it's great even if you're not a Smith nut. -SST

I agree with Tom above, find a friend with a shopsmith. This is one of the few woodworking tools that can precision drill horizontally.

This is one application in which the ShopSmith excels over ever other reasonably priced alternative. This is one of the reasons I still have my ShopSmith despite the fact I use it for very few other applications.

Guys,

Thanks for all these great suggestions. I took the first one. I was boring 5/8" holes. Don't know whether this was right or wrong, because the bolts are, nominally, 1/2", but I thought to allow a little "wiggle room" since most of the force is compression.

I drilled starting in the leg. Bored with a 1 1/8" Forstner for the washer and bolt head recess, then switched to the 5/8" twist bit and went through the rest of the leg.

Back to The Home Depot, I found just what I was looking for…a huge "ship auger" by Milwaukee, 5/8" with full width screw along its entire length that I thought would enhance alignment. I squared up the stringers in the table legs (they have little 1/2" x 1/2" x 4" tenons that fit mortises in the legs). I began boring with the twist bit and was able to get pretty far down the stringer, but not all the way. Then, I switched to the big auger and it finished the job.

I'm making my way back to the shop this evening to bore holes for the cylindrical "nuts" and should know pretty soon how it came out.

Thanks for all your help and suggestions!

George
