The kit components appear to have been spotted with a 90 degree drill and I have been finding it easier to align them initially with the same tool and then switch to a drill bit. The spotting drill can also countersink the hole if necessary. I use a ViseGrip type clamp on the drilling table but do like your setup and wish you would zoom out so we can get a more general idea of it.
Hello sir, In 0.40 you use a disc, larger than the workpiece, to position the workpiece in the chuck. Does this disk have special properties (magnetic) for example? If so would you have a link to buy it. Where did this disc have it machined to allow the part to protrude for machining? I hope for an answer and in that expectation my cordial greetings. P.K.

Hi Dana, thanks for your question. If there is any misalignment between the drill spindle and the spotted hole the drill bit will bend slightly to try and align itself with the spotted hole. If you keep going like this the hole will end up being on a slight angle, but if you loosen the clamp once the drill is cutting full width the part will move across to align itself with the drill instead. The trick is to loosen the clamp just enough so that the part can shift sideways but not start spinning. When you loosen the clamp you need to stop any drill pressure and let the drill bit sit just above the surface in the hole. Hope that helps.
Thank you for the response, it makes prefect sense. I have seen this before but never had a clamping mechanism flexible enough to make small changes on the fly.

How much yours system
I like the way you hold the part being drilled, but I don't understand why you loosen and tighten the bolt as you proceed.
