« Part 1: Introduction and Background Part 2 of Decked Out Ridgid Model R4511 Table Saw series Part 3: Improved Dust Collection »

The Herculift mobile base supplied with the saw worked well, but it wasted a lot of space under the cabinet:

In addition, the heavy (~200#) granite top and cast iron mechanism made the saw feel top heavy and somewhat unstable when moving it, due to the small caster footprint. As others have done, my solution to this condition was to redesign the mobile base with a wider caster footprint:

The wider footprint distributed the weight much more evenly and made the saw feel very stable.

The improved mobile base is a 3/4” plywood box, sized to fit the saw cabinet base, with 10” outrigger panels on each side for mounting 3” diameter double locking casters. The double locking casters were sufficient to prevent movement of the saw in use. Much of the time, locking them was not necessary. Provisions were also made for a full length drawer in the cabinet.

The outrigger panels were supported by integral gussets in the front and back panels and an additional gusset at each caster location. Dust covers were added to improve appearance and eliminate debris accumulation.

The mobile base was also designed to accept modular storage cabinets on both sides.

In case you are wondering, the mobile base and other parts were painted with Rustoleum Hammered Paint, No. 7218, Dark Bronze.
Many folks have commented that the paint makes the wood look like metal!

An integral dust collection duct was also incorporated into the top of the mobile base. Other dust collection features will be discussed in a following section.

Please stay with me, there’s much more to come…...........

Paul, I am trying to build a mobile base for my r4511, can you give me the approximate measurements of the front and back pieces? By the way, great job on this, my Herculift has been problematic and is difficult for me to adjust as it is hard to work on the concrete floor.

I love what you did to the saw!! I bought one of these saws as soon as they come out and have loved it but the base has give me problems ever since i got it! I have a small garage that I use for everything so I’m moving stuff around all the time. I have a concrete floor which is uneven bad so every time i move the saw it gets out of square a little cause it drags bad.. Could you give me some measurements on the base and also the dust shoot please.

Hi Willy,

I am unable to attach the drawings to this message. However, if you send me a personal message with your personal email address, I will send them to you in a .pdf format.

I would recommend using 5 inch double locking casters instead of the 3 inch ones I used—it will make it easier to roll around on your uneven floor.
With the 3 inch casters, my table top is about 37 inches from the floor—increasing the caster size will raise the top another inch. If that is a problem, alter the height of the base to compensate. Also, check that the 5 inch casters will swivel 360ยบ without interfering with the cabinet.
I don’t really have any design information about the dust chute—the opening in the back is dimensioned to fit a sheet metal right angle duct fitting. See the photos in the dust collection section of the blog.

Best regards,

Hi Paul,

I just bought my first table saw this weekend: a used R4511. The leg stand is pretty beat-up and high unusable, so I was scouring the net for a solution and came across your great design. I was wondering if you might be able to send me the PDF you’ve mentioned in the other comments here? As a new user to lumber jocks, I’m unable to send private messages, but my email address is (my lumber jocks username)

Thanks in advance!

Have your say...
