Broaching device

I was over at National Machine tool Co. (Cin,OH) to get some parts for one of my keyseaters which I use to cut slots in an action. We had a nice visit and the owner showed me several adaptations they had made to cut special slots for actions. By modifying the cutter profile and by making multiple passes with combinations, you can do the Mauser style action slots by this means. We didn't get into specific pricing, but by extrapolating what these devices cost new and figuring a couple of extra cutters you could get by for, say, $1,000-2,000 for a set which would do the job. Far less than for broaches and a bulldozer press. I'm thinking about trying an action which is smaller than that 50 BMG singleshot I made last winter. Multiple shallow lugs instead of interupted threads.
 
Hey papapaul

Wouldnt it be easier and cheaper if you invested into a shaper? the following pics i lifted off the web somewhere and show a similar desired profile that you are looking for........food for thought.

WOW...I haven't seen a shaper in 35 years...I don't even see them advertised for sale in used machinery lists..In fact this is the first anyone has even mentioned one, that I can recall. The other very useful machine I never see listed is the Sunnen Hone..
Great machines..

I am in the prossess of building this type of tooling right now for building my actions. it's the only reason i bought my shaper. as soon as i get some results i will post them with pics.

I had two big shapers and two planer at the same time. A six foot planer and a 12 foot planer. You can machine the complete interior of a mauser style action on one. As far as the item you show. It seems similar to the breech block on my 50 bmg single shot. It can cut one of those with the keyseater in about 10 min. Every job shop in the country (at one time) had a shaper. Mainly because rotary tooling was expensive and didn't last very long. Shapers used singlepoint cutters you could sharpen with a bench stone or bench grinder for free. In those days they had lots of cheap help called apprentices and lots of skilled people called machinists. You needed both to do any amount of work with shapers. I wish I had room for a decent sized shaper, but I don't.

And.. Yes you are correct.
 
K Battenbough, just curious, where on the net did you find those pictures?

OSHA is looking at these

Spent a few minutes of my life running vertical slotters/shapers. You can tell in a heartbeat who spent time on one. We all had a scale with a chunk taken out of it from trying to measure a keyway with the ram still in operation. :eek: :D

I worked for a used machinetool dealer. (1967-73) They had shapers there and had one set up to use. I never had the oportunity to learn to use it but did observe it making things from time to time. There was an old guy named Marsh who use to run it and the other machines in the machine shop there.

I was refering to all the flat belt machines without guards of any sort when I made the OSHA comment. probably somone's hobby I am guessing.

Whilst of no use to those stateside.

I am sat not two miles from a very lightly used Elliot shaper.

Sat in a friends garage after the demise of his late father.


Any UK side guys interested please let me know - Kev, I am in the same county as you.
 
I ran a Planer at Bay City Shovels

Also know as Jackson and Church, up in AuGres, MI. I don't miss it... She was a big one. don't remember the size exactly. Something like 5' x 15' long. Made some mean looking chips. Planed 2/3 of the backside of this part, called a Barrel, round. The other side was milled and slotted. Which held a part called the J-channel. Which when bolted to the Shuttle...Etc... Threw those planes of the decks of aircraft carriers. Long story. Sorry.

I shouldn't say I don't miss it. If I get unemployed.:eek:
 
Shapers

We use a Shaper all the time, to cut internal keyways in couplings, tiller hubs, or anything else. We single point keyways instead of using a form tool.

We broach keyways up to 5/8 wide, anything over that goes in the Shaper

The Shaper we have is an old 24 inch stroke G&L, probably made in the 40's, but it still cuts a dead straight. My Dad saved it from the scrap heap back when I was in High School, re-scraped the ram and ways, tightened everything up, and mounted a new motor. One of the first things I learned was how to set up jobs on a Shaper, whether it was plaining a flat surface, or cutting internal Keyways.

We use to have a big Ohio Shaper, it had "Dreadnought" cast on the ram. We bought it from a used machinery dealer to do one contract. We had to cut some 3 inch wide by 1.5 deep, 30 inch long keyways in some big rudder frames. The bores were also taperd 1 inch in 12. It had a 42 inch stroke, we scrapped it out about 10 years ago, didn't have any use for it after that one job............jackie

I am in Baghdad at the moment and probably wont get a chance to look at your shaper until the new year, do you know what size it is? I already have an elliot 14hr, but maybe interested if you have an 18" and in good nick.

Cheers

I bought a 7" South Bend shaper off of e-bra some five years ago with the vise for around 700.00 bucks, for the home shop guys like me they are worth there weight in gold if you have a need.

Lots of information about there care and feeding on the net and clubs for trading parts.
 
When I first started selling on ebay about 9 years ago it was crazy. I could buy an 8" logan shaper at auction locally for $50 (and get laughed at) and sell in on ebay for $850. Same for Atlas and SB 7s. I bet I sold 10-12 of them. Gradually people caught on and you had to pay more for them, and got less and eventually there wasn't enough difference to make it worthwhile. Plus, we just don't have the same kind of auctions anymore.
 
Hi Kev


hope all well over there.


The machine is a 10M, it is in dry store and not seen use for a few years.

When you return let me know and I will mail some pictures.

Last time is saw it in use, it was working fine.
