Chopper - WIP + a folder. UPDATE CHOPPER FINISHED!

I couldn't really think of anything else to do to fix my screw problem except to make the liner thicker. I thought a brass liner would be cool but I was too impatient to wait until i could get some. So i just added another ss liner to each side. It looks alright, looks just like 1 piece of steel. To make the liner lock work ill have to cut away the inner piece on the locking side. But I'll cross that bridge when i get to it.

Here's how its looking-

You could always do a little file work between the two pieces of steel. I think that no matter how hard you try that it will always be evident that there are two pieces there, so you might as well run with it and make it look like it was planned right from the start.

Yeah, I'll have to figure something out.

Thanks vic!
 
That Chopper is a BEAST!!!!! Hats off to ya :)
 
Bit of an update on the folder-

Working out where the stop pin will go by marking out it's open and closed position.

Next I'll probably cut in the lock.
 
You know, if you anodized the Titanium it would have more contrast. Maybe 18v dark bronze, or 72v gold? It wouldn't quite look like two different, non-matching metals next to each other.

The liners aren't titanium, they're 400 series ss. Can't remember which off the top of my head.
 
Yeah, I didn't bother saying anything because a thong is a whole other thing in america. Ha ha.
 
Ah, sorry, I thought you were using the Ti for the liners. Getting two pieces of steel to look like one is hard. Perhaps if you spot weld them together after you cut the lock? If you move them apart they won't line up again. I'm loving your chopper, BTW.

I remember calling them thongs until the mid 80's. Oddly enough, right until I hit puberty. Then the became flip-flops and thongs were introduced. I like the new thongs better!
 
haa ha I'm sure you do like thongs zaph. I don't really mind if you can see that it's two pieces. it doesn't look bad.
 
I didn't have time to post it last night but i got the lock cut and it's working good with zero blade play. Next i'll have to takle the ball indent.

Grinding out some space for the lock to move.

Working out where the lock should be cut.

Cutting the lock. Some people say to put the cut off wheel in the drill press and use a milling vice to slowly wind it in, back and forwards. but this is the 2nd i've done freehand with the rotary tool and i seem to get a straight enough line.

This is the most nerve racking part, getting the cut out exactly right. I cut it undersized with the rotary tool then filed about 2 strokes and put it together to check. I just kept doing it like that until it it fit. It's annoying putting it together to check all the time but it's better than taking to much off!

It works! What a relief. It's locking in to the blade at around the thickness of the liner.

Thanks for taking the time to post all this. I really enjoyed seeing your progress and I'm looking forward to the final product!
 
Tim,
That's looking really good! Lockup looks nice and solid and your lock cut is straight as an arrow this time. Very clean, what did you use to cut this one?

You inspire me to try a folder:thumbup:
 
Thanks jonny. I think everyone should at least try a folder. Theres a lot of satisfaction and triumph when each step comes together and works. Also a lot of yelling when things don't work.

I just free handed with a rotary tool with cut off discs to cut the lock.
 
Hey, thanks Neil!

I got onto the ball detent today. I also rough ground in the main bevel.

Drilled the hole 1.6mm hole and tapped the little ball bearing in. (thanks to Zaph for enlightening me to the free ball bearings inside old computer fans.)

Then with the ball in a put the folder back together and open and closed it a few times so when i pulled it apart again the ball has left a nice marking. I then drilled the hole at the end of that line. (which i forgot to take a photo of -_- )

I couldn't really tell if the ball detent was working because the blade was binding a bit of the liners but once i ground the bevel in, it freed up and now the ball detent sucks the blade in like a champ.

Oh i also forgot to mention i put some brass washers on the pivot.

Next I think I'll cut away a bit of the liner opposite of the lock so i can get a better/easier push on it. Then I'm on to bolsters! which I've never tried before.
