Very nice. Would love to see pix after it's powder coated.

Regards

P.S.: How do you like your Sky Hook? Do you use it much?

I used the Sky Hook every day for the first 3 days that I had it, and I use it about once a week. I will be using it later tonight.

Anything that can prevent a back injury is worth it’s weight in gold.

My aunt and uncle just took away the bench. I will post pictures of it after it has been powder coated white.

Indexing Plates

Today in my shop I made Indexing plates. I've drawn up hexagonal and octagonal plates for 1" and 2" stock. These plates allow you to place 2,3,4,6, or 8 features around a part. They are used to register the part in 45,60 or 90 degree increments.




A couple of shots of the build... I used 3/8" mild steel plate




Blending in the crotch area




Demo setup ... plates are used for alignment only no cutting forces act on them.




Drill-press mode

Thanks for looking Guys.

I did up a quick video of the build and demo.

I will make drawings available for these at my store.

Complete drawings for the four plates, build notes and demo setups. In the form of a digital download PDF. no waiting, no postage. $4 US Available Feb 23

those look neat Joe, but I don't understand how you can center different diameter shafts relative to the flats. Is each plate designed around a specific diameter shaft? Or is it some combination of an offset hole and the specific angles of the pointy bit?

 

[rwm]

They are not for centering. Just clocking of angles. These could replace a collet block for larger diameter work. Centering could be done by the vise.

Hey matthemuppet

It can be a little hard to get your head around but the work doesn't need to be centred in the indexer. The Index is just mounted to the work with a set screw (much like a lathe dog) and provides surfaces at exact angles to use a square against to insure that the rotation is correct. I'm showing two sizes a 1/4" - 1" and the larger one has a capacity of 2".

 

[mattthemuppet2]

so you need to rezero whatever axis you're using every time you rotate the part?

 

[Doug Gray]

1. attach indexer plate to work and leave there
2. place work in vice an use square to index one face of indexer plate perpendicular to mill table
3. mill flat or drill hole or mill slot, what ever
4. release vice
5. rotate work to next position again using square to align to next face of indexer
6. tighten vice
7. mill next feature etc etc

Hope that helps

 

[mattthemuppet2]

doh, brainfart, no need to rezero as the work relative to the vise/ cutter is the same, the plate is just used for clocking the work. Which, erm, someone might have mentioned already :O

Today i started a quick project, i need to paint couple of wheels, and from prior experience they are much easier and quicker if i can spin the wheels. Some time back i modified a old wheel bearing that i can attach in my bench vice. But the wheels that i need to paint are for a Lada niva, they have 3,5" centre bore and 5x140mm bolt pattern, too big for the wheel bearing so i decided to make me an adapter. The idea is i can bolt the adapter to the bearing and the bigger wheel on it. Couple of days ago i welded the centre on this plate and today i chuck it in my lathe and machined it. The plat did got bent from the heat of welding I did drill and tap the holes with a M8 tap and bottled it in place, now i have a ton of prep before paint.
