Circa 1950’s when men were men and miter saws weighed 280 lbs lol this baby has some cast iron. I regained a measure of sanity and backed off buying the giant 18” RAS which I didn’t have room for anyway. This Delta Milwaukee Multiplex 40-B was just about the right size and space. Some guy purchased a storage locker and this was inside. For a saw that’s older than me (I’m 51) it looks pretty good.


2HP 110 or 220 switchable
1” arbor takes 12” or 14” blades
15” cross cut capacity at 2” thickness

Why? I shopped modern sliding miter saws a couple of times, I saw a lot of the same complaints regarding accuracy and repeatability…I WILL drop kick a tool like that out of my shop into the yard so buying one just a very bad idea for me.

This Multiplex 40-B had a few things going for it. 14” blade that will get the job done on thick stock if that day comes, until then 12” blades are fine. It has lots of cast iron, I worked in a machine shop when I was younger I likes me some cast iron. Even the base is cast iron (Tim the tool man Roh Roh Roh). It has a nice compact stand I can put on a mobile base. 2HP should be enough power to get the job done. Did I mention it has lots of cast iron? I wanted a saw rigid enough to cut accurately on the first try and 100th try not something I’d have to use body English on to get a square cut. If this saw can’t do it what saw can.

I was surprised the cabinet wasn’t a rusty bucket this will clean up nicely during the restoration.

What’s with the red paint, maybe part of a process to make sure operators checked everything for tightness before using. The red paint will have to go.

That blade guard is about 1/4” thick aluminum.

Huge score Darthford! I’ve never trusted sliding radial arm saws for accuracy.I kinda like the red paint, It makes it pop.

Here’s some pics of one a guy restored, it looked like this when he started. I’m off to the store to buy a wrench big enough for that arbor nut 1 5/8” dang.

Back in the day, tools were built to last forever if taken care of. Todays tools along with everything else are designed as “throw aways”. Nothing is designed to last a long time. It’s all about sustaining a market and creating new ones. Congratuations on your find. I am always looking for old iron. Anything prior to WWII is a good deal.

That’s the thing Ron I would gladly buy a modern sliding miter saw if someone made a quality cast iron accurate saw but nobody does, its all flimsy aluminum and plastic. I can’t wait to put this saw into use it won’t be a show piece.

A cast iron miter saw would be a ridiculous concept. The whole point of a miter saw is that it is reasonably portable. If you require more heft, you want a radial arm saw – like the one you bought.

Put another way: heavy cast iron miter saws do exist. They are called radial arm saws.

Lets agree to disagree, a lightweight miter saw that can’t make a reliable cut with consistency is utterly useless imo but that’s just me.
