Until what splits? The plastic? That's why I put a tight fitting brass ferrule on the end 😁

Edit: oh, the top where the pad screws in. Yeah, I'm sure the screw will strip out first. But to be honest, I'm still finding it more comfortable at the height I'm setup to not use the pad.
However, to scrape the 45 on the straight edge I'm forced to clamp the work piece to the bench. So I may be forced to use the pad.

looking great Shawn!
the edges are always the hardest to get flat.
i always try to treat the edges very carefully
i lift up slightly when i approach the edge, or stop short altogether- leaving the edge intentionally high, then knock the edge down

Thanks Mike. I had started trying to be more cautious around the edges. So i didn't wind up with that ring around the parameter.

Nothing wrong with Sandvicks they work well.
The technique is different than with Armstrongs and the feel is different.
Sorry I can't explain it better.
You may find on other sites individuals who disparage the Sandvicks.
My scraping mentor told me to use the best scraper for the job.
They work differently due to the cutter/blade shape. A different radius (if you choose to add one) will also make a difference. Note: sometimes straight might yield the best results.
Factory handles also contribute to a different feel from what you've made.
Nothing against a shop made handle.
Not at all. More metal, more wood, steel vs aluminum handles, tubular vs flat stock, shorter vs longer.
A different handle and a different length will feel and work differently.
As will how you position yourself to the work, as well as the type of metal, and specific objectives of the task.
The above is only my learning mode opinion.... If 4gsr is mentoring you, then you are likely in great hands!!

I'm hoping to load out my Cincy TM 1D tonight at 10pm when the fork arrives.
It's been raining for 3weeks, and had light snow this morning. Am hoping we can get this done and then unloaded safely on Saturday!!

That's scary!  Lol.  I'm trying to help or corrupt Shawn.  Yep, not one scraper is a one size fit all.  I've always been a Sandvic user, it's what I pretty much learned on.  Used to have one dad made from a old power hacksaw blade.  I don't remember what happen to it after the carbide tip broke off of it.  Wish I had it today.  Oh well.  I'm too lazy to make any new ones now days.  Thanks Uglydog!  Hope your move is going good.  Ken

i have antique High Carbon Steel Scrapers, Anderson Scrapers with carbide and HSS blades, and 2 Sandvik scrapers.
i use different scrapers for different things.

i do enjoy the feel of the Anderson scraper with a carbide blade as well as my Sandvik scrapers- they both move a lot of metal, with some effort

I've already discovered how I want to change my scraper and that I'd like to make two or three more of different sizes and shapes.
I ordered a 2000 grit diamond disc wheel to make a grinder.
I'm starting to understand what I need to change to do what I need done in my setups and conditions.
My vise is very nice, solid, and handy, but it's quite high. My scraper is too long for up there. And bolting a drill press vise to my bench is too low for my height and back.
But, scraping angles I clamp in a wooden handscrew clamp, so I need a medium length handle.

And I MIGHT understand which radiuses I need on the carbides.

Here's my lapping wheel. Quick and dirty. It laps the tip at about neg 5 degrees.



A friend of mine has a Anderson with a HSS blade he cut down to about 5/8" wide from where it leaves the handle. He uses it for pin pointing on small dovetails and such. It has a really tight radius end.

Nice. I think you've shown me that before. Nice and simple.

I like it!   At work we call it Mexican engineering -and that isnt a slam - its a reference to the absolute ingenious solutions they come up with out on the factory floor when faced with a problem and little to no resources.

Yeah, down here it's called "Southern Engineering".  We have to be careful with our words now days. :(
