Thread: Scraping Projects

Yikes.....even ground it is not very flat is it. Its funny how spotting doesn't photograph very well. You think you have really even spotting and you look at the pic and go "what the ####"
With a granite plate, whats the plan for the CI one? Marking out like Joe's?

Hi Ewan,
I might have to use the real camera in future instead of the phone. The CI plates intended use is for marking out on account of I have nothing flat at the moment apart from the rock and the owner is probably going to want it back at some stage
That reminds me, I must follow up on the granite from the school.

Isn't the guy in the first video teaching flaking?

I'm almost ready to say done. and move onto the next side and square it up.

Does anyone else have a stick problem with the canode 2243 or it just me?

Hi Josh,
I havent used canode that much, mostly Marco blue™. I thought sticking just meant your blue was to thick for the level of finish you were at? When getting down towards the end I can't roll out new blue thin enough not to stick. So I'd spot then wipe it off the workpiece and spot again. Though thats one good thing about the heat, makes it easier to roll the blue thinner.

It says he worked at Moore tools, in the book Foundations of Mechanical Accuracy it says moore tools are scraped with a half moon method... Starting next to the high spot, curving into the high spot then moving out of the high spot gradually...

Yes, I do too, I think Stuart nailed it. I have only been using the canode Phil gave me, I have not tried the Marco yet. It has been so bad that I have lifted the little carbatec plate off the bench.....

I get that too with the canode. That's why I don't like it. When we first brought that Canode in from the States. I was redoing a long skinny gib of a Zayer mill. I swear it was bending the gib getting it off the plate.

I always had this in the back of my mind. With the likes of Rich King using the contrast yellow. It always about contrast. I don't get that either, I figure I can read the just blue better. I always wondered if putting the contrast yellow on, sort of lubricates the work piece, so you don't get that sticktion, and some how that makes it better.

Regards Phil.

I tried it a few different ways. super light blue, so much so that it takes the blue right off the plate. added yellow it helped a little but then stuck hard again. it seems to be the bonding of the canode to itself, added more blue to see what that would do same problem even worse. I can feel it get "thicker" and sticker the more blue that get transferred to the part. I'll estimate it takes about an extra 10-15kg of force to free it from the plate. I think I need chase up some of Marco Über Blau™.

Have we decided what's happening on Saturday Morning. I think I'll be passing by your place.

I have plenty of it mixed up.

I watched the video at the library .

He doesn't explain what the orange substance is , he applies it onto the work face - It looks like the rubbing compound you polish old duco with on cars ?

And, he didn't check to see if the face he was scraping is exactly 90 degrees to the other face ? These are just observations for a novice ..Mike

Yeah I think so, I just had a quick word with Ray, we would both like to come along so we will follow you up in the ute. Does that sound ok?
