Craig said, Did you glue your arm plates together in pairs and gang drill/ream them as one per the build notes? Using my mill DRO on each plate, I ended up with one spacer pin hole that was out by a smidge and had to re-drill the two arms spacer pin holes as a pair.

Most often a smidge becomes part and parcel of any project and doesn't interfere with the final outcome. Just saying!

Ain't that the truth!

If you can do a higher risk operation before you invest a lot of time in machining, it makes sense to do it in that order. It certainly lowers my stress level to do things that way.

More truth! Been there, done that too! Feel exactly the same way!

But it's still funny!

Stress??? This is too fun to be stressful, for me its not about the part I am making, its the journey of making it that is the fun part that's where I get the enjoyment so naturally I want to do the new/most difficult part first because it will bring the most reward and continue to build my skills. I will when possible do a practice run on more difficult/unsure tasks to build confidence for a final usable product.

Yes I glued the arm plates together, but on one pair the glue let go when I was clamping it in the vise and this resulted in a small misalignment of the holes. A little filing took care of it. If I were to do it again I would put a small tack weld on the arms.

Just wondering what kind of glue you used?

I still can't weld worth crap. So I'm also wondering if a pair of sacrificial clamping screws wouldn't be just as effective. They could be removed when they are no longer required and the holes drilled out to become decorative weight reducing features.

I wonder if gluing the arm plates together, and then to a sacrificial aluminium plate would work. Then the arm plates could be clamped to the aluminium plate?

I’m very impressed with the way Joe Pie uses fixtures on his YouTube videos.

I used standard superglue. To release the glue just heat the parts with a propane torch. Use a wire buffer wheel to remove any residual glue

I'm not a fan of superglue. It requires a super tight fit.

If I were doing it, I'd use epoxy which will also let go with a little heat.

Still leaning toward screws......

I generally like Joe Pie. Sometimes he can be a bit snotty, but he knows his stuff and so I can forgive him for it. Like most youtube authors, his videos are also too long.

Yes, he is a fixture wizard!

This 3/8" O1 tool steel hinge pin did my tap in:mad: Doesn't look good for salvaging the hinge pin either.

Get a good TIG and you'll change your mind.
