Chips a flyin, and apparently some bullets :-O
Well, round one with making a threading indicator went Bust. I have never made a worm gear using an Acme thread (no Wile E. Coyote jokes please, it is a real type of thread) The last worm gear I made was just to see if I could do it and I used a standard American threading for it, and the hob I used was a tap. This go-round, I made the hob using the threading feature on the Southbend (one learning curve down, and what a learning experience it has been, and still is.) I went ahead and did my math and that was all good but I did not gash the blank. The goal is to have 32 teeth on the gear. That covers 4” of the lead screw and (the theory anyways) is to take up slack and backlash in the indicator so that you can more accurately cut threads. Well, that blank is ruined by 35 teeth and the center is rough as hell and the teeth are walking all over each other there. The outside edges are fine (excepting that whole 35 tooth issue) and the gear even travels well. (surprisingly!) BUT, it measures out 4 and 3/8ths of the leadscrew, and while that means its taking up more back lash, it would not be accurate between cuts. (It may be, but I don’t even want to try and figure out how that math would work for the indicator knob.)
So, I am back at the layout bench with a new piece of stock. This one is going to get another step added in to the procedure. I will mount it to the rotary table and drill out 32- 1/16” holes on the outer line then machine it down to where the holes are cut in half. (can you cut a space of air in half or is that you open it up by half? Oh, that line of thought will get me second guessing whole levels of learning. LOL)
Now, for those that wish to see things in action, you are going to have to wait. I totally failed at the picture taking thing this round. I will start with what I am doing in the mornin’. There will be another post up with pics. Especially for China to show his dad. I am sure that Mr Syndrome will get a kick out of what the machine is producing for itself.
Now, on to current events. I was informed about some incidents at some gun shows that struck me as possible problems in the greater picture. I don’t have links nor the inclination to go looking for them at this time, but what I heard about could be played out as conspiracy tactics. People getting busted with loaded weapons at gun shows. People shooting themselves while loading their new .45 in the parking lot of a gunshow, etc. No conspiracy here in my opinion, but the media is going to play up how ‘dangerous’ gunshows are. Sadly, I can’t say I have heard one incident at a gunshow in several years until recently. Seems to me that so many noobs grabbing up guns are making mistakes with at least one (several actually) of Col.Coopers rules of safe gun operation. The only way you screw up and shoot yourself is if you have your booger hook on the bangswitch and its pointing at something you value (IE YOU!) Bang, two rules busted and that doesn’t even take into account that loading your gun at a gun show is just showing how immature and impatient you are. Maybe someone needs to do a little growin up before they go getting a ‘big ugly’ for whatever reason: potential gun grab aside.
Watch the media and see if they play this one out (like I expect they will). If not, I would wonder why as it would fit into their gungrabbing agenda perfectly. Or, if not, it was due to the fact that not enough blood was spilled (the more likely reason they won’t touch it)
Anywhoo’s, sleep for a few than back to the shop after taking the Voo out chasin squirrels in the morn. Talk at ya sometime tomorrow (with pics, I swear.)
