Czech Tension clamp height

[petercoffey]

I have 2 Czech Tension machines & just sold one...the buyer complained that the clamps are too high in relation to the stringbed height...I have strung about a hundred rackets with each machine without noticing anything out of the ordinary. When I string the mains the string is almost to the solid part of the clamp & when I do the crosses the mains sometimes touch the clamps between the teeth...The buyer says the clamps should grip in the first 1/4 " of the teeth & no deeper...I think that's nuts and he's just looking for a reason to return the machine...Both my machines have the same height on the clamps..

They are the single action...anybody else have Czech machines & is this even an issue? Thanks

The lower the better. On the Gamma clamps the string can go below the valley of the tines on mains. On crosses the mains keep the cross string from going any lower.

Two things to say about this:

1. If the guy bought the machine after having a good look at it-it's not your problem.

2. I would think the clamps were made to work on the machine as they are. It is hard to imagine Czech making all these machines with badly engineered clamp height.

The only thing I have ever heard about the Czech clamps is that the single action clamps can be a real problem to work. Adjust them to where they hold the string nicely and then they are too hard to open and close. Adjust them so that they open and close nicely and they don't hold the string.

Let him know he is better off having someone else string the frames.

cRaZy :shock:

The buyer says the clamps should grip in the first 1/4 " of the teeth & no deeper.

Says who? The string should sit in the clamp as deeply as possible. Otherwise, the clamp may not hold the string under tension.

I have strung on a couple of Czechs so I have some experience with them.

As noted above the single action clamps had a reputation for crushing strings, being hard to adjust and/or not clamping too well. The dual action had no such issues. If you are confident that clamps were okay when you sold him the machine, then as far as you are concerned, the clamps are okay. End of story.

I think your buyer has no idea what he is talking about. Is he new to stringing? If so, that would explain his confusion.

I had strung at least a hundred frames on that machine... it was purchased from the original owner who did maybe 10 frames on it...I never had to do any adjustment on them except to adjust for gauge..found them very easy to work with... bought another czech machine that needed alot of work to get it as smooth as the first, but it was a matter of adjusting to the correct tolerances.. it's still not quite as smooth as the first machine but close enough... I've now done about a hundred rackets on the second machine...again with no complaints from me or my customers. I had read that the Czech machines had a few issues when they first came out relating to the hold down system, but that was addressed in the later versions...I thought it would be money better spent than just buying an eagnas or a glide bar machine. I think I made the right choice. preferring it over my friends neos.... It was a sweet machine... not sure why he didn't dig it.

Did you modify that machine? I have never seen a Czech like that.

Most are all silver and have those weird yellow mounting supports. Are you sure it is a Czech, doesn't seem to say Czech Tension on it although some of the parts, like the adjustment knobs look very Czech-ish to me.

All the Czechs I have seen looked sort of like this style wise. This is a table top but the upright ones had a similar design in terms of colors.

I didn't like the plain gray so I painted it http://tt.tennis-warehouse.com/showthread.php?t=296180 ... other than that...I found some replacement nylon inserts for the head/throat supports, so I replaced those...It's totally stock otherwise & it is the one pictured in the manual I have... the second machine I have has yellow cones but they are hourglass shaped (I milled some new ones out of nylon similar to those on the first machine to replace them... much more solid).. I think there were complaints about the yellow cones in your picture so they went to the yellow hourglass style then they updated the machine with the metal/nylon supports... at least that's what I can figure from the articles I've read

Yes, I had the hour glass yellow things, too.

What is the model number of the upright? Is it FS 750?

Looks better painted red and I like the mounting you did. Looks like an Eagnas now.

One thing I recall about those machines was how HEAVY they were.

So, was it a Tru Ten or a Czech or do you think they were the same machine branded differently. Look very similar.

Mine said truten on the post.. can't really find a model # on it anywhere

I've seen a couple different ones as well, not sure where they fit in the time line

very heavy...seem to be well made...solid. I think the Czech was for Europe & the TruTen was imported for US same machine

I'm guessing the machine I sold was one of the last they made before trying to rebrand for Wilson (as the Prestige Stinging machine) & then finally folding
