I'm beginning to think Rob has a fly cutter fetish! 

Interesting looking collection of scrapers there.  The yellow one looks like one you would take with you for a night on the town in NCL.  I'm guessing that is for getting into dovetails and other tight spaces?  I too would like to see some of the home made ones.

Any chance of a photo of your shop made scrapers  :poke:

Rob

Sure - here they are. Obviously not as posh-looking as your stuff as I only have a cheap camera without all the special effects yours has got  :D

The one with the short tip and new handle I made by silver soldering a carbide slip gauge to a steel shank. The others I made after buying a bunch of different-shaped tips off eBay. The sqauare one i made for scraping rust off ways etc but at the moment it's doing serious duty stripping 70 years of paint of my Monarch lathe. The rounded one is a bit too small a radius for scraping but that also makes a great paint scraper for internal curves.

Hi there, Rob,

I was looking at your photo of the cast iron slab being fly-cut and noticed the clamps holding the slab down to the table.

They look very much like the gizmos I've seen listed for sale on eBay and described as face-plate jaws (no names - no pack-drill!).

Thing is, the 'buy-it-now' price for those face-plate jaws seems awfully expensive!   :scratch:   :scratch:   :scratch:   :scratch:

Do they have some hidden mechanism that's not visible in the seller's photos or are they hyper-strong or what?
Best regards,

Pete W.

If you can keep your head when all about you are losing theirs, you haven't seen the latest design change-note!

Hi Pete ,,,, Face plate jaws are normally sold in a set of four , with each jaw having its own adjustment, just like a four jaw chuck ,  , making a set for my CUB lathe is on my too do list  :dremel: . The ones I am using on the mill have one fixed jaw and one moving jaw , basically your mill table becomes one big vice .

The sets you looked at on Ebay were probably a VERY LARGE set .

Hi there, Rob,

Thank you for your explanation.

The jaws I saw on eBay were described as 8 inch and another as 6 inch - I thought that referred to the size of the faceplate but I guess it really refers to the size of the jaw!!!   :bugeye:   :bugeye:   :bugeye:   :bugeye:   :bugeye:   :bugeye:

Came home today from work to fined a parcel sitting there for me  :)  Pete had very kindly made me two of his carbide scrapers .




Being the impatient git that I am I was straight into the shop to try them out ,they still need handles making .  :palm:



Result , they are far far superior to the HSS ones I have been using , they cut like a dream   :med:

Pete had lapped a 5 deg neg rake , my crappy camera skills dont do justice to the edge ,but  I can say is its a  lot better than my scraper sharpening .



One of the two has a thinner blade , just the job for getting into dovetails .




Thanks again Pete ,,,,,,,,,,,,,I really owe you one  :beer:

Rob,

Considering that the chinese probably melted down a DS&G, or a Weiler, etc for the iron to make that 626, I would only be fair if you took that saddle to your furnace, and cast a Wok :)

Your work is inspirational for us. Maybe the quality manager of the Chester 626 plant (someone had to sign the certificate right?) should be sent a link to this thread!

Nooo problemo!

I would have cut file tangs on them but I was worried they might come out of the packaging in the post.

I hope the tips stay put - I had no idea it would be so hard silver soldering them on with butane gas. Had to cheat a bit to get enough heat from the canister but I won't say how coz it wasn't exactly a right and proper thing to do :)

A flycutter is also on my list of tools to do, but I have not found a figure for the angle of the face/toolbit. It looks like more than 10 degrees but not so much as 20.

Rob, what angle did you choose for the smaller one just above?

Hi Peter ,  I went for 20 degrees  :thumbup:

Hi Nick ,,,,,,,, I used good old PVC tape  to mask these parts ,there are allot of other ways to mask parts for plating .

Wow, Rob, what kind of plating is that?

Neotech, I'm with you, it would be great to learn how to achieve better finishes on what we make. I certainly could use help with that.
I love it when a Plan B comes together!

Thanks Peter and Steve  :beer:

Steve the plating is my home brewed Nickle plate , just something I am messing with  :zap:


Well I managed to straighten up the Y way bearing surface  on the knee.



Now both surfaces are on the same plain , no bend , flat and square both ways with the Z . And the compound now has no rock to it .  :)




Just need to fit the dovetail and make some tapered gibs  :dremel:

Rob
