Getting back to gun building:
I'm new at this myself and have taken a slightly different tack. I invested in several good videos, which I have watched time and again. I also assembled several kits, those "cheap, nasty, Spanish" things that at least get you working hands on. And, from a purely financial standpoint, if you really screw up on one of these, you aren't out a whole lot.
I figured rather than starting with a project costing several hundred dollars, I risked ruining a 75.00 kit. And basically the worst I could end up with was a ruined stock, so the rest of my investment was still safe.
Now that I've got some better parts, I see why people so strongly recommend the higher quality (and priced) items. But the first projects were for practice and I made mistakes that cost me a lot less. I also took more risks (cutting a dovetail into a barrel worth a few dollars is much less stressful than trying your first dovetail on two hundred dollars worth of fine steel). And stoning and polishing a rusty old Jukar lock until it works almost as smoothly as a fine Chambers has it's own kind of reward.
Now I'm doing my first "raw" build of a stock, and it's going on the same little Jukar pistol that I first built. Yes, it's a lot of work on a cheap gun (the darned thing has probably cost me hundreds of dollars in the past year
) but when I do put out the money for a Chambers kit (I already have my eye on one) I'll have some background and experience to bring to the building of it.
Just my opinion...
