Just printed the MacDaddy v2.0 frame. Next is the sling and brace mount, feed ramp and whatever else I'll need. If you've printed this before, what do you recommend watching out for?

Should be mostly smooth sailing from here. Don't force any pinholes on the receiver -- ream them first. Especially the front takedown screw.

You can get metal feedramps from several vendors if printing one feels sketch or you encounter feed issues: https://www.avesrails.com/Mac-Daddy-Feed-Ramp-Aluminum_p_50.html?applypromo=index

I need to find a tap kit. Figure I might as well buy one if I'm going to be doing this more often. Any recommendations?

[–] TheShittinator 2 points 2 months ago (1 children)

Honestly? Most of the time it's pins held in place by springs or clamping forces from a nut on the other end. And when we do thread into plastic, you either ream undersized and send a machine screw in -- the friction will heat it up and it'll mold threads into place -- or we melt in brass heat-set inserts. A tap kit doesn't have much application for most builds.

Get you some good sets of imperial and metric drillbits. You'll want them to drill through metal later on, so nab some nice cobalt ones.

Well I've got plenty of drill bits that's for sure. If this continues I'll have to end up investing in a drill press. I recently did the heat-set inserts for a GPU cooler that I printed, it was surprisingly cathartic. I'm hoping to have the money to buy the rest of the shit for the MacDaddy within the next few months. Definitely looking forward to having something that I "built".
