Better drill press vise?

Throwing this out there @David_R8 - if you have an old larger throat C clamp you could probably “salvage” yourself an acme screw

And a nut to sleeve in as well. Interesting idea!

OOPS my bad. here's joe's build video for the follower rest:

Another recycle source is the screw from a scissors jack.

The last Acme tread rod I needed( for a cannon barrel elevation jack) I purchased from a local Bolt Supply House establishment . They had a large selection (1/4"-1 1/4") of the rods & corresponding nuts in regular stock.

Why does it need to be ACME thread?

 

[DavidR8]

From what I know Acme is stronger due to the thread form.
Truthfully it probably wouldn't make much differenence for this application.

Thank you sir, that is genius. I happen to have two pieces of 6" x 24" x1/2" phenolic.

So would the commercially made follow rest buggered the threads or was it more a matter of not being able to get in that tight with the pre-made rest?

Of course a "cannon barrel elevation jack" ! I think we need a picture of that historic alarms @historicalarms

 

[Dabbler]

right.

Why does it need to be ACME thread?

Acme threads don't bind up as bad as pointed threads when being advanced or loosened under pressure ...less friction than to the larger area of a thread with longer slope to a thread crown and also less thread count per inch reduces engagement per inch of object but retains strength .

David R8 - I think Fastener Force has Acme rod, don't know the cost but would be the quickest to get going if there are no shoulders required.

Sorry I missed this post Mike. I'll give them a call today.

Doubleboost posted a video yesterday cutting a acme for a cross slide.

 

[DavidR8]

Holy smokes, I just got a quote for 1/2-10 Acme rod.
$64.61 delivered for 12....







FEET!

Cut off what you need and sell the rest by the foot?

That's what I'm thinking

I've had pretty good luck with those guys.
Did they tell you what class the thread is?

 

[DavidR8]

I don’t actually but I will ask.

 

[YotaBota]

I'm just curious about the class, for what you are doing is the class important?

 

[DavidR8]

I don’t ‘think’ so honestly. Anything will be better the 6B class thread that’s currently in the vise body.
