Brown. It looked like auto grease and had the same consistency, but was sort of tacky.
A Cheap Temporary Fix...
I have a Flex 940 that is about 8 years old, and one of my ConeLock clamp bases stripped out and would no longer lock down. In an attempt to fix it, I tried to disassemble the clamp to figure out which part needed to be replaced. As I was doing this, I found that the "channel nut" that fits into the slot on the base was locked/stripped into place and that I could not easily unscrew it. Using two lock grips, I tried to force it, and the entire bolt sheared in half!!! Here's an exploded view of the results:
I e-mailed Maxline/Eagnas to find out how much it would cost to replace the parts, but did not get a reply in a timely manner. Meanwhile, I really needed to string my racquets as I had broken the strings in all my personal frames and wanted to get back out on the court (without having to pay for a tennis store to string the racquets).
After reading through this thread, I made a short trip down to our local Lowe's Home Improvement store and purchased the following items:
138188 Metric Wing Nut 8MM-1.25 for $1.09
138144 Metric Flat Washers 8MM for $0.80
138129 Hex Head Bolt 8MM-1.24X50MM for $0.92
138182 Metric Hex Nuts 8MM (5) for $0.76
The total spend was $3.86 with tax.
When I got home, I used some WD40 and lock grips to get the old "channel nut" off of the broken bolt. I then used the new bolt, 2 of the new washers, 2 of the new nuts, the old swivel base, the 4 old top washers, and the new wing nut to reassemle the base. Here is a view of what I put together and how it looks assembled:
The new mechanism now clamps on and off by a simple turn of the wing nut and seems to work fine. I've strung 2 racquets since trying this and the base locks down like it should.
To note, I only string about 25 or 30 frames per year, so I don't heavily use the machine and I don't care about speed when stringing. I do look at this as a temporary solution until I can do a more permanent one that might work better. If I was stringing professionally, perhaps the wing nut would not be fun or efficient to use. However, it sure was cheap, and I thought I share in case someone else runs into a similar jam.
Flex 940 Turntable Wobble
I've had a Flex 940 for nearly five years and it's been a really reliable machine. I've used a Wise on it since the first week.
My only real complaint with the 940 is that the turntable continually wobbles. It seems I have to take an Allen wrench to the main bolt under the turntable every 3-4 frames to tighten it, only to have it loosen (and wobble again) after a few more frames. I've tried Lok-tite, but that didn't seem to work very well. Does anyone know of a viable solution to stop this wobbling??
I know this thread is a little old maybe the user is still on here I was wondering how this set up buying from McMaster went?
His last post was in July of 2010 but he does accept emails maybe you should send him one if you want the answer
I'm going to resurrect this thread...
I had the stripped thread issue on my Flex 940, so I bought exactly what was suggested here. I did have to drill out the base a little to fit the 3/8" instead of 8mm, and I also got a pair of 3/8" ID fender washers from Loews just because I thought it needed them.
But, it all works great!! Easier to tighten because of the thrust bearing and smoother too. Maybe I'm imagining it, but I think there is less drawback as well. Thanks TT forums!
