Broaches SUCK

Guide bushings are an expensive PITA

Same here! lol

Hahahaha same

I just saw the video where Adam purchased one. Its a good machine. We have broached several dozen key ways on it. I even used it to scrape in a repair I made on an internal spline that was damaged. Thanks for watching the video. The Ole Man

mike's video is a little squished. maybe you can pillarbox instead of squishing

I ended up with a Davis Keyseater after researching both them and these Morrison machines. The Davis uses the multi-tooth broach cutters which are much more expensive new. Luckily I was able to get almost every size used for a great price. The Davis machines can use a limited size bushing to do bigger bores, so no higher cost there. The Davis machine can do a keyway like the one in this video in about 2 minutes, way faster than this Morrison single cutter can. Plus the Davis strokes much faster.

This work could be done with a shaper however I believe the setup time to be less. The advantages I see for keyways again has to do with the amount of time to set up, it also takes very little power and the foot print is very small. I have seen these machines with attachments for doing internal splines, taper bores etc. and plan to make a few attachments when we get time. I believe the advantage the machine has over a broach is that a keyway can be put into a bore regardless of the size of the bore or the size of the key. What I mean by this is that if you had an odd ball bore like 2.264 the machine doesn't care where as if you were using a broach it wouldn't be a standard size like 2.250 so you would need to make a custom broach guide. Also the size of keyway as compared to the bore is endless. You could put an 1/8" keyway or slot in a 3" bore for example with the machine, again with a conventional broach and broach guide that wouldn't be possible with a standard set and would require some custom work. Again all this could be done with a shaper but I believe the setup time would be longer. We don't currently have a shaper in our shop but would love to get one but would still keep this machine.

@@MamcoMachining Got it, thanks for explaining.

@@boomblooka if you got creative you could do a lot of shaper operations on one of these, you could make gears if you had the patience! Those tools look very much shop make able out of standard HSS stock.

So glad you found us again! And yes it is a very neat way to do this task.

Thanks for watching the video. The same company makes newer hydraulic units but the are pricey especially for a small shop like ours since its not used very often. The Ole Man

It does that by design. The table moves the part out of the way on the return stroke, like a clapper on a shaper. Notice that it moves away then just as the cutting stroke starts, it returns to its position. Also notice the control at the operators lower left moving in in time with the table.

Thanks for watching video. Yes I would agree great machine. You advise advise about not hand feeding is well taken. I always use the auto feed and as mentioned in the video I even baby it a bit and disengage feed after a few strokes so that the cuts can catch up a bit to keep from exerting to much pressure on the cutter. They also have an adapter plate to cut keys in tapered hubs. I have been looking for a used one to have on hand. We plant to take the table off in the near future to clean up the ways and gib. But really for what we do it works great. Again thanks for watching The Ole Man
