This project started with getting the ‘kit’ from Harbor Freight, as a ‘starter’. I did not feel that, for the price I
could not produce what came in the kit. The MDF table top itself is very nice and solid, about 1.25”
thick, and the overall layout of the table is good. It goes without saying (my opinion) – there are some items that deserve addressing and correction, then this top will be a good addition to the shop drill press.
Mounting does not match my table
This was expected to be the biggest issue, I was not disappointed…. This was corrected by re-dilling the ‘pockets’ on the table that hold the 5/16” ‘T’ nuts. As delivered there are two pockets located along the centerline on the ‘X’ axis. With them in line with the centerline, the top will not be secure unless
additional pockets and supports are added (found this out the hard way, see ‘my screw-up’ in picture 2). The best solution for securing the movement on both the ‘X’, ‘Y’ and ‘Z’ axies was to relocate the holes so there is more separation between them, and there are more of them. The 4 pockets were cut so the pocket spacing is as large as possible with my drill press table, which will provide more stability attaching the two tables together.
’T’ Track on table surface is poorly installed
Initially there were 3 countersunk #8 sheetmetal screws holding the track(s) onto the MDF. Left as it was, it would only be a matter of time before they would pull out, probably right in the middle of some project. The 3 sheetmetal screws were replaced w/8-32 hurricane nuts and 8-32×0.5 machine screws, in pocket recesses on the bottom of the table.
A ‘Cross’ ‘T’ Track is Needed
A third piece of ‘T’ Track needs to be installed along the ‘X’ axis so that a third holddown becomes
available. The mounting of the ‘T’ track is the same as the other two ‘T’ tracks.
Fence Poorly designed not shown
This is a very ‘poor’ excuse for a fence that might be used for something other than decoration. There is a stop block but there is no ‘T’ track for it, it simply uses a groove cut in the mdf, sad….. The first order of business will be to re-route the slot where it is, and install ‘T’ track in the slot. The holddown will then fit nicely on the tabletop ‘T’ track.
Following is the url for a place to get the ‘T’ nuts, referred to here as Hurricane Nuts (I have no idea for the name change). I stumbled across them while searching for something else. This place has them in 3 sizes, 8-32, 10-32, and 1/4-20. I predict once you use these, you’ll never go back to the ones at the Big Box Store. Plus they average out to 0.12 each….. A bargain!!!
