Eleon - Self Centering Dowel Jig with Elongated Jaws and Extra Wide Clamp - Durable Aluminum Alloy Dowel Drill Guide - Blue

Only suitable for end grain dowels. Not useful for face dowels. Returned it for a refund and purchased another type that also allows face dowels.

This Dowel jig exceeded my expectations. I’ve had others in a similar price range and no longer use them, because accuracy saves money and is the most important aspect, especially when using expensive wood species, as there’s no room for errors. It is clearly built to a high precision, no sloppiness in its moving parts whatsoever, very accurate in its alignment, hefty in its weight, and well packaged. The company stated that they are considering selling replacement inserts in the near future, as there’s no doubt that the screw in inserts will wear down with repeated drill bit usage. The jig itself should last a lifetime of use, as long as you take care of it and treat it as the precision instrument it clearly is. Furthermore, Amazon sent me a returned used item, and the inserts were worn down. I contacted the manufacturer and spoke with Ryan who quickly rectified the issue. Bravo!! Another reason to purchase this jig.

Great piece of equipment

I purchased this jig to install some floating shelves that needed a perfectly centered metal dowel. One end of the dowel or post screws into a wall stud while the other slides into a drilled hole in the shelf. I used it for 5 shelves and for the first four it worked perfectly. However for the fifth, it became off centered and my drill bit kept going off center and drilling through my shelf on either the top or bottom. The instructions told you what you might need to do if this happens to ‘readjust’ the jig, but so far I haven’t been able to successfully make the proper adjustments. I’ll keep trying to adjust but kind of funky adjustment process. If I can figure out how to properly adjust this thing, I’ll come back and give it 5 stars.

Before doing anything else with this jig, perform the adjustment procedure mentioned in the October 9, 2024 review by Cainiac. Basically, I did that by tightening, tweaking the centering adjustment, loosening, and re-tightening the jig on a 3/4" thick piece of lumber like I was planning to drill the 3/4" side. I did that until I was sure that the jig was appropriately centered before locking everything down as Cainiac suggested. I have been edge-drilling plywood that is about 0.473" thick for dowels and cam lock screw holes. So, the holes have to be centered or the pieces will be ruined. The accuracy has been consistently great, which allows me to quickly drill all the holes with a minimum of difficulty. The jig is very functional and a great value. The only thing that I would like to see in addition to what it already does would be inserts to accommodate more drill bit sizes to allow for uses beyond just doweling.
