i assume you have oiled the crap out of your clamps already? i think the major diff between the switch/fast is that the switch uses a conical surface to pull the bottom T-piece up. the advantage being two thing: - the angle of the cone needs lighter action to engage - the rotational ability means that the bottom piece (the T cross section brass piece) doesn't need to rotate, and thus can have a larger surface area result in less binding. the whole conical piece actually never rotate with respect to the table, only the clamp base does. whereas in the fast action design, the whole thing including the bottom piece rotates, and therefor the bottom piece is shaped that way, but that doesn't provide a lot of surface area for lube to work. to be honest though, the idea and design of the clamping mechanism is really good. but for some reason the design or the machining of the T-piece, or the design of the "track" is lacking. the track is really just part of the extruded Aluminum turntable, with some sort of hardened surface. that surface just don't slide very well against the annodize base of the clampbase. either that, or they need to rethink the geometry. maybe raise the track a little.
I don't have anything against the tracks, it seems to go smooth enough for me. What I do not like is that the quick action base pretty much makes you turn a screw to tighten the base and prevent it from moving. That takes efforts and it even makes the turntable bounce back and forth, which I hate. I like the idea of being able to lock the base with just a flick. I have no tools or machinery here. I will have to find them, which shouldn't be too hard considering I'm in an engineering school
another idea is to cut and glue a piece of teflon sheet at the bottom of the base, and forget about oiling the top of the track.
OK so I don't know if i am unluky or what but .. i have a delema with the machine ALREADY...!!! after about 10 rack mostly at 26~32 lbs... now i am experiencing a rocking of the turn table .. not exesive but it rocks about 2mm up and down... i have double and triple check the 4 bolts in the center they are all tight.. and the bearing bolt are tight aswell... anyone else got this or is it just me @!@
@Kwun and other experts Does anyone knows: 1) Are the Gamma clamps 12mm just like the Eagnas ones? 2) Are Victor clamps for 7030,7031 12mm as well? 3) If the Gamma Switch Action Cam-Lock Clamps fit into the tracks on the typical Eagnas/Victor7026,7027,7031/Pro'sPro turntables? 4) If the entire Gamma turntable fit into a typical Eagnas/Victor7026,7027 horizontal tension bar? Thanks
Gamma clamps are 12mm. I wouldn't be surprised if every piece from Eagnas could fit on Gamma machines, the machines are just copies. I don't know about Victor machines.
That will depend on what turntable to what machine... i have notice the 4 bolt in the middle of both machine and they are pretty similar... i can measure it if you need.
10 already!! in which direction is the rocking? you said up and down, you get it by lifting it straight up and down? or the edge of the table is rocking up and down if you rock the whole table sideways? i think if i try to rock the table sideways, i get around 0.5mm of play at the outer knobs. but that's about it.
i tried the clamp only .. not the base.. maybe one day if i am bored enough to take them apart lol :S
@Biggy Yea i also saw the 4 bolts n nuts and would be great if you can measure them at your convenience. If best you can try to interchange them and let us know I m hoping i can buy a Gamma turntable to upgrade my spare Eagnas
I've always thought the cone (and the bit that contacts it) could have done with some vertical machining marks - this way they'd still be easy to engage, but the machining marks would add some sideways friction to stop the base turning under lock. It'd be almost impossible to convert the locking type to the spring type - the lock type has a lever that engages directly with the brake pad underneath, while the spring type engages the pad via a cam shaft and a cam follower.
