Thread: Douglas repair

Nice work Phil and good job on the video, I haven't even got that far myself.

Dave

A pretty stylish little production there on YouTube Phil. I reckon Steven would be applauding your efforts.

BT

ps. Have you ever posted photos of your cross drilling rig?

Thanks Dave, I still have a couple of things to do yet. There is a new sliding block set up in it at the moment ready to be machined

Thanks Bob, even though I know you are lying through your teeth
Quietly confident I haven't posted any pics of the cross drilling rig but I will on the weekend. Hell, I could make a movie

I am definitely not bullsh.tting Philip. I am impressed with your machining, cinematographic and editorial skills.

Hi Phil,

Great video, I enjoyed watching that, it told the story well, except for one tiny criticism..... There was no video of the shaper running.... I'm looking forward to seeing the shearing cutter in action..

The 5/16 x 7/16 HSS for the Armstrong shaper holder arrived in the mail the other day, and the granddaughter, took the parcel outside and she was throwing the bits of steel around the back yard...

Regards
Ray

HI SW,

Nice video, I too would of liked to see your shaper in action. I used my the other day to clean up some vice jaws, great fun.

Cheers Ben.

Phil
Enjoyed the great video, well done.
I would have absolutely, no idea how to complete a video like you have accomplished.
A few weeks back my camera "croaked" packed it in, it was time to get a new camera.
Purchased a Nikon Coolpix, along the lines of BT, & his suggestion to get this camera.
Been learning how to stear it, must get & take some photos soon !
regards
Bruce

Hi Bruce,
well done on the camera purchase but as you haven't taken a pic of the camera then it didn't happen

Well I tried the shear tool today and although I still have to work on the angles a bit and perhaps a keener edge, I have to say I am not entirely disappointed with the results.
Needless to say there is a video of the shaper in action (another bad one) with the results at the end.

Shaper Shear tool trials - YouTube
ps let me know if the files are too big to download.

Phil, these tools work best with a small DOC; I use around .2mm tops. That's eight thou to you. It's really just for finishing. You should be able to get a satin look. Here's mine in action. Will see if I can do a sketch of the tool.

Hi Bob,
here are the pics of the cross drilling rig.
All that is required is a piece of 1" shaft in the chuck to align the rig on centre height and the DRO on zero for doing drilling on a PCD.
The rest is (hopefully) self explanatory.

Thanks Bryan,
I knew they were supposed to have a small depth of cut and that is what I thought I was doing.
In the end I could barely tell if I was turning the handle and it seemed as if it was still too deep.

Phil

Looks pretty good Phil, you can go straight from shaper to scraping.

Josh was getting mirror finish off the shearing tool the other day, I think it was curved and very sharp.. he mentioned that for cast iron he thought the edge should be flatter, not curved as much as for steel, but like Bryan said the DOC needs to be very light.

Ray

It's harder than I thought to draw the shear tool in sketchup. I could take a photo, but John Hill has already done it, and mine is based closely on his: ArtfulBodger.net: Shaper: Cutters. As you've figured out, a medium feed is ok because it's a broad-nosed tool. A finely honed edge does make a difference - you notice as soon as it dulls. You'll suss it out Phil, you're not as silly as you look . Let us know if you have specific questions. Or post a pic of your tool if you want comments on that.

Nice work on the vids by the way, and on the shaper repairs too. I love how quiet your Dougie is.

PS: I use a dial indicator on my tool slide. Try 4 or 5 thou DOC.

I remember Josh saying about the curved face now. Mine is flat so I will put a curve on it and see how that goes.

Hi Bryan,
I see the face on John Hills' is curved as well. I went with the 45 deg. instead of 25 deg as he specifies so I will give that a shot as well.
The bit of work I did has obviously put the gears back in alignment by a long way and my only regret is not taking more care in the first set up in the 4 jaw of the bull gear.
I'm still kicking myself as I now realise it could have been even quieter, although it is pretty damn quiet now.
I will regrind the tool and post a pic for your perusal.

Phil

Looking real good Phil

Nice repair and wow, Bryan is right that machine sounds sweet as, so quiet!

The vids are looking good to, nice production work there.

I have only tried the shear tool once, i was still getting lines like a pointed tool would give. What gets me is which way to mount the cutter, with the nose grind marks going with the cut or perpendicular to the cut?

I also get gear noise in the cut, i have to spent some time one day and count it and work out which gear it is coming from.....
