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 

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 

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!            

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

[Rob.Wilson]

Hi Pete ,,,,,,,,  those scrappers look very pro    dont forget to show us the results of your scrapping

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  . 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 .

[Pete W.]

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!!!

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 . 



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

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

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!

Mark

[Rob.Wilson]

  Thanks Mark  ,,,,,,,,,but i dont think there is a quality control manager , due to there is no actual quality to control

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

[Rob.Wilson]

Hi Pete , the tips look well fixed  I have bummed some mahogany from Mick to make handles 


Hi Lads , I managed to finish off the arbors today , spent most of the weekend sorting out my shops and its still not done 

All done . 




cutters the wrong  way round 





The arbors will hold up to a 1/2" wide  cutter .




Now back on with the mill

Very nice Mate
Clever how your camera can do matt and shinney on one setting

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?

[NickG]

 :bow:Rob, you've probably said this before but how do you mask parts of a component when plating?

[micktoon]

Top job Rob  , ...........one of the best jobs in the world would be quality control manager in your shop...............just sit drinking tea ( at home ) knowing there is no point even going into work , never mind looking at anything as you know everything is under control.......................the only quality being ..................Top Quality

 Keep up the good work.

Cheers Mick

Nice work Rob.

[NeoTech]

Uhm, so you boys ever considered knitting.. it seems like a fairly acomplishble hobby.. 

Rob.. you must do a surface finishing tutorial.. now.. *point towards whatever forum section*

Hi Peter ,  I went for 20 degrees 

:bow:Rob, you've probably said this before but how do you mask parts of a component when plating?

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


Cheers Rob

[PeterE]

Thanks a lot Rob! 

Your nicely made tools are a real inspiration, and they do create tool envy

[vtsteam]

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.

[Rob.Wilson]

Thanks Peter and Steve 

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


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
