Re: Jessem's new dowelling jig
I noticed that some dowels were loose on my paralign, but I have dowels from two different sources and there is slight difference in their diameter so I assumed it was just the dowels. Upon reading the above I went and tested the drill bits.
One that comes with the paralign is indeed a little larger than the true 3/8" bit. The dowels from my "thinner batch" are very loose inside hole drilled with the Jessem drill but they are nice and snug with a true 3/8".
As for the other jig, I was considering it solely because it also offers 1/2" option which is great for heavier joinery. I spend some time looking for reviews and the only one I found was overall positive, but with one negative remark about clamping the jig to the material. As shown in the promo material the clamping is in reality too weak to keep the jig in place while a hole is being drill - the jig moves defeating its purpose. This is not a serious issue as two, and stronger clamps could be used.
I settled for paralign since the main reason for me buying the other one would be the 1/2" capacity, which is available only as an add-on to the 3/8" default configuration. So at the $150 price point I decided I'd be better off with the $160 (on sale) paralign. For the occasiona 1/2" dowels I will use my old self centering jig. Not as convenient but does the job.
