Question: Some of the same reviews for the 4210 appear for the 4212
Document: In reading the several reviews posted on Amazon, I decieded to go with the Porter Cable 4212. Well,that decision was a good one and the Reviews were right on with the praise of the DoveTail machine. Simply put, "great", and so convenient with the new locking handles. Much improved from some years ago when the adjustments were not "so easy."
I have seen several reviews stating the instructions are next to worthless. I don't understand this because my jig had plain and very well written instructions. I was also able to download the supplemental instruction manual which gives instructions on various decorative dovetails and box joints that can be created with the jig. I originally bought the 4212 but bumped it up to the 4216 model to cut 1/4 inch dovetails and box joints.
I have never used a dovetail machine before. Using Porter Cable 4212 is easy, my first attempt produced results far better than I expected. I was able to make tight fitting joints with very little practice. The 4212 is a well made and easy to use. The initial setup is not as complicated as some reviews indicated. The most important thing I could recommend is to read the manual and become familiar with all the different parts and functions.
In honesty the other reviews just don't do this justice. I really wasn't prepared for how solid and heavy it was.The 4212 comes with two templates allowing for dovetails, blind dovetails and dado cuts. Also included in the package is the router bits for dovetailing and straight cuts in addition to the relevant template guides. What's not obvious is that this unit is intended to routers using 1/2&#34; router bits whereas I have a router that uses 1/4&#34; bits.
I purchased the P-C 4212 jig primarily to help me make drawers quickly and accurately. Before buying it I was worried that the jig would be too fussy or time consuming to set up properly, or that it might not make good joints. After reading lots of reviews I decided to take the plunge and I am happy to say that  my fears were mostly unwarranted. So far the performance of this jig has been excellent. The manual is well written and the instructions are easy to follow and precise.
PC makes this DT jig in three models: 4210, 4212, and 4216. The differences are the number of templates included. Otherwise, they are the same. Review the specs for each to be sure you are getting the template or templates you require.As usual, this is a solid PC product: simple and straightforward. I made a box to house the jig, templates and tools and it doubles as a stand to raise the jig off the workbench to a more convenient height.
Item arrived promtly from Amazon. Jig worked perfectly. Set up was easy. Learning curve is quick. Easier that other jigs I own. Have only used for half blind, but other dovetails appear to be equally easy.
I must admit that as I read these reviews, I was prepared for some poor instructions and difficult setup.Scanned the instruction and went through a half dozen attempts without clean joints.
For the price it is an excellent jig. Besides the great reviews given in Amazon, other wood working magazines rated it very highly as well. Like any tool you have to practice with it to appreciate it and I do! I have to agree with other reviewers that the manual is terrible. (hence the 4 stars instead of 5) I did not experience any shipping damage problems that others reported.
Again, something not provided.6) The instruction manual leaves something to be desired and makes no mention of a supplemental manual available online from PC.With regards to the lack of positional feedback on the jig, based upon pictures, reviews, and articles, these criticisms seem applicable to many dovetail jigs on the market, others pertain to the quality of manufacture.
Answer: yes
