Just purchased and used for the first time. Easy set-up. low vibe saw. Converting to 220VAC makes the extension cord small and you don't have a lot of power loss. It is 13Amps at 120VAC but only 6.5 at 220 so a cord with 14 or 16 gauge is more than adequate. I store the saw in the garage and roll it out when I need it a 25f extension cord is perfect and with 220 VAC power only has to be 16 gauge. Nice. With 120 V I'd need a 10-12 gauge cord or would lose power.. The fence guide is not as smooth as it could be but with a bit of sweat to align it it works OK. Blade adjust is smooth. I wish it came with a dado insert. It is not hard to make your own but a saw of this capacity is a great tool for those cabinet dados. I also make butcher block cutting boards and this has plenty of power to cut through 8/4 maple. Over all I am happy with all my Rigid equipment and do recommend it to others. It does seem that Home depot is reducing many items from their stock though. Just try and find a spindle sander. Even this product was difficult to find in store. Is something going on?
leecraft makes both. About 33 bucks each. Some people say they bought them directly from Rigid through home depot at the order desk for $25. I only found that out after I bought mine on amazon. I don;t even know if they are still available through HD but it would be worth a try in store. They are not on the web site.
I haven't seen a pre fab unit but you could easily make one from 14 5/8 x 27 inch 3/4 melamine glue ups mounted as shown on the extension insert page. All you need to do is rout out the hole for a router plate. MCLS makes a 1 1/4 inch top that can be cut down but there are no pre fab brackets for the 4512 But because there are holes in the extension tops and the end bracket you could fabricate something to mount the router table level with the 4512 top and use the rip fence with a box fence plate attached or just drill some holes and use your MCLS fence. You can" rigid 4512 router table" and see some photos.
