Duplicate a benchrest stock

[wvlongshot]

Excluding setup time, how long does it take to duplicate a benchrest style stock in say laminated walnut/maple? I know there's all kinds of variables, but just a rough idea of actual time of the router being run.

A stock, is pretty much a stock to me on a duplicator. When i use pattern stocks that are already configured, actual cutting/inletting takes 2-3 hours.
Scribing and rough-cutting the blank another hour or so.

Honestly, I've only ever used mine to run my own stocks from custom patterns I design, but there would be additional time needed for a one-off setup.

My actual run time on a MBR style 700 inlet is hour and a half to hour 45 minutes. Normally have another half hour layout and cut on bandsaw and another half hour or so once it's off the duplicator till it's all cleaned up and ready for us to ship out.

A lot depends on which duplicating machine you’re using, too.

So if you got the stereo hooked up, coffee pot plugged in, and the bathroom unpacked....

Have you set up your shop yet?

I have 2 Don Allen duplicators. They work really well and are accurate.

Thanks guys for the info. As if I don't already have enough to do, kinda thinking about toying with one.

Short answer: NO
Still getting the last details done to make wifey happy. I got as far as buying two wire shelving units from Home Depot, put them together and filled them with my unpacked boxes. I’m having trouble locating a place to buy the machinery I need. Quality machinery, that is. Might get started next week. Thanks for asking.

I will second what Josh said," A LOT depends on the machine you have".

I don't know the accuracy of the Allen machines, but it is my understanding you have the ability to make an accurate inlet on them. They are top of the line machines.

With the machine I use to do the outside, I am able to keep the accuracy within .006 which is fine for the profile, but is not up to my standards for the inlet. I have a second machine which I have modified just for inletting. More busy work, but less hand work to get the inlet to what I want.

The profile of a common benchrest stock is a simple pattern to duplicate. However, completing a copy that has most of the work done to the final profile, and inletted accurately is a lot more complicated.

I suppose inletting would matter more to me if I gave a crap about it, every stock I've ever made is intentionally overcut on the inletting to allow for bedding.

.006? Your stocks must look a hell of a lot better than any other stock I've seen come off a duplicator looking rough as hell and requiring hours of sanding.

I intentionally oversize and shim my tracing styluses so the outside of the stock is cut oversize to allow for all the required sanding. Thousandths, is not even in my vocabulary when it comes to wood...

Pretty much what I do too.

Huge difference between a stock made on a cnc router and a duplicator. I will not work with one that was made on a duplicator any more. Id look into a cnc router.

What's your reason for this statement?

Sorry, I didn't explain correctly.

If I would inlet with the machine I do the outside with, the best I can do on ONE side of the inlet is plus or minus .006. That can be a total of .012 across an inlet. That means I would have to inlet approximately .010 smaller on each side of the inlet to make sure it didn't get too large. As the machine cuts, it flexes the stock slightly. The outside is not the problem. I needed something to get me closer on the inlet so I didn't have to do so much hand work.

When I don't care about bedding showing, no problem, however, an action can be inletted for a wood to metal fit at the top and still allow for bedding. At that point, thousandths matter.

Time and aggravation. It takes me many times longer to put an inlet in a stock that is not straight and shaped the same on both sides. You have to cheat it to make it look right and it never really will be. A straight stock with equal shaped halves only takes a few minutes to setup and tram in and the inlet will be straight and level because you have something to work off of. When you set a stock up in the mill and tram the top and find center the inlet should not drift and the trigger guard should come out centered. Thats not been my experience with stocks made on a duplicator. I inlet about 50 a year, and have worked with most of the more popular stocks. But not every one of course. This is just my general experience.

Unless something has changed. I have not talked to him in a while but I will edit my post if thats no longer the case.

I painted 3 stocks for Bob this past summer through our conversation it sounded like things were going good.
I could be wrong. I hope not!
I lost his cell # when I busted my phone. I should call the business #

Ok I just spent 2 hours talking with the "NEW"
owner of xringstocks Jason.
Great guy, very knowledgeable and sounds like he'll be a pleasure for everyone to work with.
He has an extensive background in cnc machining and business.
Looking forward to the future of xringstocks.

As far as duplicating a stock, wouldn't it be as straight as the pattern?
