I already asked this question several years ago I ask it again to check if anything has changed since the last time;
Did anyone of you mounted a 3HP motor (from Steel City or not) on his R4511.
I have been thinking about his since day #1 had the saw, I never yet did it but I am still thinking about it.
Did any you replaced the fence?
I cannot get the fence to not move all over the place when I tight it.
I am thinking about buying a 3 HP cabinet saw, Amazon has a very good deal on a SteelCity but I am still hesitating
Thanks

I know a number of people have upgraded the fence to a T2 or Biesemeyer. I have the stock fence on mine with the addition of UMHW, but I’ve never had tightening issues with it.

Can’t say anything about upgrading the motor, but I am intrigued about the possibility.

Brandon I contacted SteelCity to have price on the motor from them, I have no answer yet.
When I have an answer I shall post it.
The best would be to know the motor frame size to ship around for one but I am too lazy to take my motor out since I built a cabinet around my saw and that would be job to get it out.
Do you have an easy access to the motor on your saw?
If yes, can you get the specifications from it?
In addition I built a router table on my table saw,as a right extension table but it does not really work as well as I would like and I am thinking about mounting a cast iron router table to replace it.
Which leads me to thinks that it would be easier and may be cheaper to replace the whole thing.
Thanks.

If you can get a look at the plate on your motor there
is usually enough information on there to look up the
specs of the particular motor online. Motors obviously
vary in size, so the main thing is to make sure you don’t
get a motor which is too large.

Loran, As I wrote above for me to get the motor is a major project as my saw is “enclosed” in a cabinet. This why I ask if anyone else has an easy access to the motor to look at it for me.
Thanks

I’ll see what I can do about looking at the plate.

Thank you
What is important is the “frame”.

b2rtch,

I am restoring a 4511 as we speak. I looked for a motor plate on mine and could not find one. I also installed a Biesemeyer BC30 fence on mine. Solid as a rock. IMHO the stock fence on the 4511 is a POS. I will probably install a router table extension at a later date. If I ever have to replace my motor, I will also look into getting a 3hp at that time. Keep an eye out for my restoration post once I am finished. It will have a sequence of photos detailing my restoration.

I Just received this information from SteelCity for the parts and price to transform a 1 3/4HP to a true 3HP:

Hello
The motor is OR70428 and I believe it will work. There are more items to change for it to become a true 3hp system. However, you may be able to use just the motor and change the plug. I have pasted the info below. I had this saved for the other machines listed in RED and just added the R4511 after reviewing the manual briefly. We take visa or MC and I have included the CC form for use by email or fax.
Item Code (Part #) quantity Serial # Product Number (Internal Information) override unit price
change 1.75 to 3 hp 35600 35903 35911 only and R4511
OR70428 1 3 HP MOTOR $349.99
OR70148 1 3HP Pulley wider style pulley to match motor and belt $14.99
OR91762 2 1/4×1/4” set screw for larger pulley .99 each $1.98
OR70144 1 spacer fits onto blade arbour shaft to accommodate pulley $6.99
SC10391 or OR70147 1 belt multi V belt for new pulley and motor $14.99
OR70143 1 3HP Pulley wider style pulley for the arbour $11.99

I typically advise against going over 2hp with a motor upgrade for a 1hp to 1.5hp saw, but many of the Steel City/Orion made saws are made to accept either, so as long as they’re confirming it’s ok, no reason not to if you’re willing to spend the money.

Many times good alignment and the right blade can make a huge difference in how powerful the saw feels, but I assume you’ve done all that you can. A fence change should also be a nice improvement.

Is it worth the money or should I buy a bigger saw?
Now this is my question.
I only pay $299.00 for the saw brand spanking new, add to that 473.91=772.91.
If I was to buy a new 10” cabinet saw I would have to basically double that money.
In addition I could use the motor from the table saw on my band saw.
Or I could sale this saw for more that I pay for and buy a new one.

it all boils down to one thing and one thing only – what you want to do.

Having power in your motor is one thing…. transmitting that power to your blade is another. The rigidity of the frame work also comes very much into play.

all the 3 HP saws I’ve seen have …

1. three sheeve pullies
&
2. very robust trunions

I, personally, would upgrade my saw to a package that was designed from the ground up to transmit that level of power to a sufficently rigid frame, that wouldn’t flex under the increased loading.

All of the single phase 3 HP motors I’ve seen are really expensive. You could put a lot of time and money into this “upgrade”, only to find yourself unhappy with the outcomes.

My vote is buy a nice new saw. You can only put so much lipstick on a pig.
