I have order the M5 x 0.8mm version of the kit and requested expedited shipping with PR370214P through ecommerce.

Hello,

Kevin and Tom have arrived at JLab and have started laying out the aluminum pieces that will attach the exit window to the RICH.

To mark the aluminum to be able to drill holes, they bought a tool called a transfer screw set. The transfer screws are inserted into the existing threaded holes on RICH, the aluminum placed in the correct position, and tapped with a hammer. This accurately transfers the hole locations to the aluminum for drilling.

While test fitting the aluminum, we found that the existing threaded holes on RICH are sized for M5 screws. The plans for the exit window involved using  M8 sized screws and the transfer screw set sent is for M8 sized threaded holes.


DSG will search online for a M5 transfer screw set and have it shipped as soon as possible.

As a contingency plan, we have already talked to JLab Machine Shop and they would be able to machine a make-shift transfer screw set out of set screws. This machining would take about one day and cost ~$300. We will arrange the work with Machine Shop first thing in the morning if we are unable to find a set of M5 transfer screws online.

Best regards,
Tyler
