Custom-Made Stringing Machine Parts

If I had the equipment... but I don't. I can CAD with the best of 'em, though

.

The diabolo certainly forces the string into line with the plates, but that's the ONLY reason I use the diabolo, and it puts the gripper a good few inches further away from the turntable. I've done test-pulls on many strings and concluded that gripper marks only manifest with mine after three or four pulls (and we shouldn't be pulling the same string three or four times anyway!).

the sheet aluminunumium piece is actually 18mm thick. which i think mean we can bypass the mill and go straight to a waterjet.

let me talk to my machining friend to see how much that will cost...

Well, if it's cheaper for each of us to get one, I'll design mine if he/she is amenable

certainly will save raw material cost as 2 L's can fit into a rectangular block better than 1 L. only slightly better though.

an alternative would be a custom shop.

custom CNC shop will charge less for more pieces. but they also charge an arm and a leg if there are many cuts.

i roughly tried to price something like this and it came out to US$80/each for a quantity of 2 pieces.

How much would it cost if there is a demand for more than 10 pieces?

Pete are you interested? do you use your WISE anymore?

We can infer from his query that he uses at least eight of them

10 pieces is $27.xx each
6 pieces is $31.xx each
5 pieces is $33.xx each
4 pieces is $36.xx each
3 pieces is $41.xx each
2 pieces is $50.xx each
1 piece is $80.xx each

something like that. i am just doing a rough drawing. the more detail i add, the higher the cost.

this is for custom CNC milled part.

more params to be tweaked as well.

Mark A, any chance you can make a CAD drawing for the piece? my CAD skills dates back to the early 1990s. there are places who can give us a quote for CNCing the part if we give them the DXF file.

kwun, if you can email me a dimensioned drawing or photo (even a hand-drawn sketch would do), I can reproduce the original and do some mock-ups of the proposed mod.

I'd rather not go into the guts of my WISE if I can possibly avoid it - I just took the cover off and I don't fancy messing with anything I found underneath...

I certainly agree to that!!!! Cheers Michal^^

+100 I couldn't agree more

I had the pleasure of testing some of these recently - picture below. Much the same as the Pilot/Combo version, but they have the added advantage of lowering the racket by 8-10 mm, giving a more horizontal pull from the tensioner.

great pics Mark ....
how do you compare to the original side-support ?
do you still have 360 degree of Wise2086 ?

Mark: What do you thing about tennis/squash issue?

WISE still has 360 rotation, and the shaft clearance is roughly 1/4 inch.

Mark: What do you thing about tennis/squash issue?

The V-shaped version is excellent for tennis, but squash needs a much longer "throat" to reach the narrwo end of the racket - I'll draw something up in CAD to illustrate when I get a minute
