Precision Matthews PM-728VT CNC conversion

Let me ask your thoughts on fixture plates like the SMW https://saundersmachineworks.com/collections/smw-fixture-plates/products/precision-matthews-pm-728vt-aluminum-fixture-tooling-plate.


Should I go for a conventional 4” machine vise (ordered, but can cancel) or a fixture plate with their accessories and small vise? Thanks man.

That's a nice plate to have but it's something you can make yourself later on. I bought 2 5" vises and plan to make a plate similar to the one your referring to which I call "T" plate. I keep the vises on the machine and when I need the plate I use vises to secure it. Similar to this pic.

I very much like the idea of making it later. What vise do you recommend, as a top of the line hobbyist item — I know it’s like asking about the tallest midget, but I am sure you get what I am saying.

I looked at the 4” Kurt but at $600 would definitely not be able to afford two. So two at around 250-300 would work with this plan.

You might want to check out the Glacern vises. I have a 4” on my mill and it’s really well done.

I purchased two 5" vises from Precision Matthews and are pretty decent. Not the top of the line but they work.

I am very tempted to cancel my current vise order (backordered to 3/26) and get a Glacern 4" standard vise.

Question: if I want to add a second vise (to hold the fixture plate, for example, or long stock), should I order both upfront and ask Glacern to match their height? Or can I add hte second later and not worry about the possible height discrepancy?

Check out teco vises too. When I bought my 6" glacern, the teco was similarly priced, maybe a couple $$ cheaper, but I don't remember exactly. Don't get me wrong, I'm happy with the glacern, but when I bought my new mill, the seller gave me 2 teco vises with it. They are much bigger, beefier and heavier. I use all 3 just the same, but I prefer the teco.
 
Glacern is having a sale right now. 5% and 10% off. Just received an email from them.

I went on their website but didn’t see anything about the sale. Meanwhile MSC direct sells the 4 inch Kurt vise for about the same price [500 some dollars] so That’s what I’m going with. I had an order with Kurt themselves who are backordered until late March, while MSC had them in stock, so I switched the order.

Meanwhile I had emergency surgery last Monday and now I am convalescing at home, but can’t work in the garage and the project is on hold probably for as long as another week.

Got the Kurt DX4 and installed, and indicated it. Looks liek a fine piece of kit, although for the price I would have preferred an integral chip shield to protect the lead screw. The next step will be to fabricate a base for it.

What suggestions do you have in terms of anchoring to the concrete floor? This is a residential garage with a standard, non-tension concrete slab. What diameter screw to use? I am thinking of using 5/16" x 3" Tapcon screws from Home Depot, unless y'allz recommend otherwise.
