After more than one month of trial and error with my RDT design crossbow, I decided to build a "classical" match target crossbow, and to put "on hold" the RDT design. In order to do so, I ordered a 95lb (and a 150lb too) taiwan bows, and start working.
The stock will be 1''x2'' section and 30'' long made from solid 6060 dural I'm planning to use 0.2 inch diameter arrows that will slide on a teflon rail inserted into the aluminum stock. I already milled the stock in order to accommodate the teflon rail:
The trigger mechanism will come inserted (dead fit) in the 0.5'' groove (with clearance for the trigger lever):
The limbs will be fitted into a "riser" and will be hold by these bushings: (machined from aluminum)
The infancy stage of the shoulder rest:
I'm also planning the use non-optical sites siding on dovetail tracks and adjusted by fine threads (i don't have at disposal micrometer threads) (i'm working on the design now)
There are 3 trigger options that i'm debating about which to use:
1. "classical" excalibur style:
2. A russian forum inspiration model (the original model was also posted by IVO on "trigger section"). I used ball bearings for increased smoothness:
3. a simple romanian design with both holding bolts above the rail (much easier to fit into the small groove left for the mechanism): (I've seen this mechanism working greatly on a 170lb crossbow)
And if we are talking about precision crossbow, these are the tools that i'm working with for acquiring this:
In the last picture there is not the rail inclined with 0.1 degrees, but the holding table
