It's an upside down "L" shape, how about a sacrificial block that turns the "L"
into a block?

Hi
I would do it about the same way you did it first, with a few changes.
First, clamp it as high as possible on the vertical part. Get rid of the
cylinder, or if the vise is not clamping properly without, use a thinner
one (say 6-8 mm diameter) placed as close to the upper lip as possible.
I would send the .dxf to the laser shop and collect the cut-and-bent parts
in a few days. Some parts are not worth machining when there's a far easier
practical solution.

Hi all,
Everyone has their own favorite way of workholding. Without good work
holding nothing good follows. Thin angle stock I clamp in the vise with
a rectangular block as suggested below. However, my most common approach

The whole point of the exercise is to learn how to use LCNC and the CAM

the laser shop in the first place.

John,
Two suggestions:
1. I have experienced the same symptoms in the past, and it turned out
to be the bolts securing my Y axis nut (which has a square flanged base)
moving under the inertial load of the table.
2. My approach to machining the part might be to not cut the box section

I'm traveling for work today so can't dig deeper until tonight or tomorrow.
Thanks for the suggestions. Sent from my Samsung S10

Hi Marcus,
Too late to play with the machine but your point #2 raises some questions.
I did first square off the ends of the box and bring it to within 0.001" of the
target size.
With the rough edges scraped off I then mounted it in the mill horizontally,
cut the two slots and then cut the width

How does one know what size tabs and how many?
I view this as a mystical black art.
For me, the basic idea is to
(a) support the part to prevent damage when it separates from the
parent, to stop it catching the cutter for example. In that case,
