There hasn't been a lot of other users sharing information about this machine, so I thought I'd share my experience so far with it and Quality Machine/Precision Matthews. It took about a month to receive. In stock, time needed to install the DRO, Road Runner Freight over a week in Transit to CA. Not bad. Tracking by RRF was lacking, but I supposed those companies aren't FedEx.

I wish I had a photo of it prior to uncrating, but the guy bringing it down on the liftgate was scaring the crap out of me. The pallet wasn't clearing the floor of the truck, and he was jogging it to get it past the floor while not having it tip over. If it had, my machine, driveway and house would have sustained damage.

But, it landed nicely and in fine shape. I had to take the crate apart to inspect it and get it in the garage on the driver's pallet jack (remember to tip your delivery guy and tell him you will before you ask him to go above and beyond) but we got it inside and safe. From there I had to chop the pallet so my neighbor and I could get it on the floor using my HF 2-T engine hoist. Note: my floor is very smooth, but the cast iron casters do not roll easily or spin well at all when loaded. No surprise, I supposed, but I can't complain for the price. The crate was made of high-quality materials.

Checking the work envelope, a 5 gallon pail fit easily. For a size comparison, the now disbanded trio of the PM, my Benchmaster and my Grizzly G0704 now living up in Sacramento.

A 4" Glacern vise fits this table very nicely. I do need a speed handle, though.

The motor is 3hp 3phase. There was an option for a single phase motor, but that was half the cost of a VFD. Having very recently installed a VFD on the Benchmaster after learning about them via Tubalcain on Youtube (and really enjoying how it turned out), the step-pulley/VFD seemed like a no-brainer (not to mention $1k cheaper, much more simple than variable speed and in stock.) Programming the VFD takes some learning, but rewiring the motor was simple enough. I bought switches and a box from Wolf Automation and made a bracket out of a bit of brazed and painted bed frame and scrap. Currently it's got a start button, reverse/jog button, speed pot and e-stop. The VFD is temporarily mounted on the wall, but I intend to box it up at some point. Wiring is via 18g seven-conductor solid strand sprinkler wire (made in USA, actually) that I picked up at Home Despot. I needed eight wires, so I ran one extra wire next to the seven and wrapped them up in tape and loom.

I'm not thrilled with my switch arrangement and programming as is, but it's easy enough to change how it's set up at some future date. For now, it's smooth and powerful. I've drilled half a dozen holes in some scrap steel, and it's so much more robust than the Grizzly (I know, obvious.) I can't fit a Bridgeport with my low ceiling (I still curse the builder who's surely been dead for decades) so this was the biggest alternative I could find. I considered the Grizzly 8x30 Rockwell (?) clone they sell, but lack of adjustment for the Y axis killed my interest. Plus the overall height was taller than this one when packed for shipping and I was worried about getting it inside.

As mentioned, the crate was very well made of quality materials. So much so that I salvaged what I could and made myself a new 3'x5' bench of which 80% or so was shipping materials with the rest of the 2x4s coming from my old bench. The rest was staples, nails and firewood (which I found this evening burned extremely well.)

My experience with Quality Machine was very positive. Matt answered all of my questions and gave me a bunch of parameters he suggests for the VFD (which I wanted to install/program myself.) Road Runner Freight delivered with no damage that I can find and I got a new bench out of it. My only gripe is the DRO isn't here because I'm told the last batch had issues and were returned. But better than sending defective stuff, and I can certainly read dials well enough to get some things going. I'd like to build a boring head as a first or second project.

Hey Ray, what's the run-in procedure for this rig? The manual has four pages of "Don't operate while blind, stinking drunk", "Don't operate with long hair or jewelry", etc. but no mention of a run-in procedure. Any idea? I emailed Matt earlier, but probably after business hours. Thanks for any help here. Edit: Matt says no real break-in needed, just start using it.

Thanks for the review/experience. I don't know how I missed this thread.

Now that you have used it for a while what is your experience/impression of it?

No break-in required really. That's not a sump type head so just lube the obvious moving/rotating components. I would recommend a good cleaning with rubbing alcohol followed by a complete lube (way oil) when first getting it. After that, just use it. I don't recall if yours was outfitted with a one-shot oil system. That makes life a little easier.

They are really nice machines and we sell them mainly to machine and prototype shops. We sell them and never hear a word from the customers afterward -which is always a good thing. Outside of the hobby group (I actively promote outside of this forum) this is my #1 requested/sold piece of equipment. We also sell a lot of the 1340GT lathes at the small end and various huge lathes/mills at the high end.

Long story short, this is a pro-line piece of equipment.

Mike,

I'll see if I can get something interesting together for you this weekend. I can tell you that it's all positive compared to the Grizzly I had and the BPs I've used.

Not sure what I'll tackle the next few days, but I've got a spouse asking for kitchen window replacement or repair ($$$$$ vs. my labor plus $20), and some people coming forward asking for bicycles. Maybe I'll be moving into one of you guys doing some work on the side, too.

Here's the completed PM bench for starters:

That would be awesome Ryan. I would love to see some chips coming off of that thing. It is getting me even more excited to get mine up and running.

Unfortunately, I had some minor surgery this morning and have nothing better to do than sit here and read forums and watch youtube videos for the next couple of days. I haven't had this kind of "down time" in quite a while. I busted butt getting the shop cleared out of customer work to gear up for today because the wife won't let me even step foot in the shop due to the drugs.

Nice looking workbench also Ryan.

Mike.
 
Nothing too thrilling for you, Mike. I was rehabbing wood windows and building bikes for most of the weekend, but I used the 935 for some RC aircraft building for my dad. He asked me to mostly complete a landing carriage for him, so I did. Handy skills for that sort of thing.

Current setup:

I'm not crazy about the yellow, but the controls seem to work well and are in a good location.

My solution to getting each side high enough to drill for the axles.

Ready for wheel collars and to mount to the fuselage. Darn good thing I've got a 3/4 ton mill to get this heavy work done.

I also used the last bit of the shipping container from the 935 to close off a window I'm refurbishing. Lots of work, but not much money to fix up old windows. Especially compared to what replacements cost. Wow. Something to be said for deferred maintenance, though. The glaze is easier to remove.

Stripped and ready for some repair work. And I only broke one pane of glass to get here.

I sure like weekends.

I think that is the most interesting setup I have ever seen. That is some real ingenuity there. And most importantly, it worked.

Admittedly, the BenchMaster horizontal would have made for a much more simple operation, but the Y travel stopped working properly, so I think there is some chip removal needed. In retrospect, the setup/take-down for the vertical might have not taken much less time than fixing the BM, but it worked.

Ryan,

That brings back memories. I repaired a lot of those over the years back in my remodeling days. Repaired more old double-hungs than I care to think about. It's amazing how much abuse the old growth wood windows will take compared to modern wood windows.

Oh and nice machine too!

Jay
