Glen and fellow mechanics, a few questions:
I'm about to make a set of these carpet feet this weekend for a GC4 table I just purchased (not delivered yet).
1. Can you tell me the exact diameter the leg levelers are?
I measured the GC4's at my local pool room, but I could not get a very accurate diameter because the vertical part of the leg obscures the center. I did not have a tailor's tape measure with me to measure the circumference either. I estimated the diameter at 8", but again, I couldn't get the tape measure right over the center with the tools I had with me.
2. I read the earlier post, but just to double check, the bottom of the GC4 leg is completely flat? And that's why a second backing piece of wood is not required to keep the nail heads from moving?
3. 7/8" is the target number for the nail's exposed length? (I might use thicker wood as I want my table taller)
4. Regarding the angle iron bracing for the GC4 frame: I have some scrap angle iron from years ago in my shop that has the holes punced in it every inch. Is this type suitable for the bracing? I think the one you have in the picture posted where you made your own holes might be a slightly thicker gauge metal.
5. Again regarding the angle iron bracing on the GC4: I crawled around my local room's floor looking under their GC4 tables. They have the same frame as in the picture you posted, that needs the bracing. I felt the wood of the cross member and the long member, and they were not planer. They were off maybe a 1/32" inch or so. I obviously do not know if they were planer from the slate side of the joint.
It is my understanding that GC4's (I could be wrong) are assembled at the factory, then while assembled, the top of the frame is planed smooth and planer. Then they are disassembled and shipped. This means the bottom of the frame can have steps at the joint areas, but the top would still be planer.
So my concern is if we now put an angle iron brace on the bottom of the joint, the top of the joint will have a step, and the bottom would be planer. Maybe none of this matters as the slate is on shims anyway? Can you set me straight if this matters or not? I've never seen the slate installed on a table, so I'm not sure how important it is for the frame to be planer.
6. It looks like you are using lag bolts for the bracing? What size are they? I'm going to make a HD trip to pick them up...
Thank you.
