Jack from Russia

Project description
Jack’s project was a Mechanical Linkage set.
Firstly we made a prototype for him as per his drawings required, but we found some problems.

Problems
1) There was no linkage effect.
2) The tube were loose even though all bolts are very tightly, also up and down plate had big gap .
After researching the drawings with the prototype, we got the solution as follow

Solution
1) The hook was too short to connect the shaft —-enlarge the hook length(3.5mm) to make sure it can connect the shaft correctly
2)The tube increase the process of Knurling and reduce outer diameter then it will be tightly and there is no gap between the plates.

Jack ordered 500 sets of Linkage Set after solved the problem , all of the parts worked well .
We are happy that helped Jack shorten the time for new products to appear on the market.
