I still taste sawdust from the night I finally quit crawling on the cold floor under my Bosch RA1181.
The bit dropped mid-cut, the cabinet door blank wobbled, and my temper snapped.
I jammed a flashlight between my teeth, squinted at the tilted motor, and thought, There has to be a better way.
A week later a lift sat on the plate, and every job since has felt smooth.
Today you get the road map I did not have.
No vague hype.
Just plain talk that guides you from first question to final turn of the crank.
By the end you will set perfect bit height from above the table and lock it solid on the first try.
Why a Lift Matters on This Table
The built-in height adjuster on the Bosch 1617 fixed base works, yet it flexes when you push heavy stock.
A lift swaps that shaky scheme for a lead screw and carriage that glide.
Spin the handle on top, the motor slides in tiny steps, then a lock holds it tight.
Nothing drifts.
The change sounds small, but you feel it fast.
Cut lines stay crisp.
Repeat cuts match day after day.
Bit swaps happen above the plate, so your knees stay clean.
Quick Gains You Feel on Cut One
- Fine moves that repeat turn the crank one full circle, the bit rises about one millimeter.
- Zero guesswork set the dial to zero at test depth, come back next week, dial the same mark, cut fits again.
- Faster bit changes slide the collet above the plate, pop the wrench, swap, done.
- Flat plate the insert stays flush, so stock glides with no snags.
Those four perks shave minutes from every setup and wipe out lurking errors.
Start With Fit A Simple Compatibility Check
The Bosch RA1181 uses a plate that is smaller than many aftermarket lifts.
Grab a ruler before you click Add to Cart.
- Plate opening
The cavity measures about 11-1/2 inches by 9-1/8 inches.
Corners show a 3/8 inch radius.
A cardboard template helps when you test. - Motor body
Most lifts aimed at this table clamp a round body that reads 3-1/2 inches in diameter.
That covers Bosch 1617, Porter Cable 690, DeWalt 618, Makita RF1101, and many more.
Measure your motor, read twice. - Insert ring options
If you use guide bushings for templates, pick a lift that packs a ring drilled for the common 1-1/4 inch guide. - Above-table access
The lead screw sits dead center.
You will drill a single hole through the aluminum top so the crank drops in.
Leave clear space for that handle.
Once those four points line up, the rest feels easy.
Three Lifts That Make Sense
1. O Skool RTS017 Drop-In Ease
This plate was cut for the Bosch RA1181 and its sister RA1171.
Slide it in, twist three cam wheels, done.
Why it shines
- Smooth crank with zero backlash, so no wiggle when you stop.
- Dial ring resets to zero, great for batch work.
- Five insert rings, one accepts guide bushings.
- Simple lever lock that bites hard with a quick flick.
Who loves it
Any woodworker who wants plug-and-play speed and runs a mid-size motor.
2. JessEm Rout-R-Lift II Fits With A Trim
Many shops praise this lift for silky travel.
The plate is just a touch wide for the Bosch cavity.
Sand or rout one-sixteenth inch from each long side, keep the 3/8 inch corner curve, drill new holes, and it sits flat.
Why it shines
- Carriage rides on guides, so the motor stays square.
- Micro height shifts feel like turning a safe dial.
Who loves it
Makers who already own the unit or plan a future upgrade to a larger table.
3. Full-Size Lifts Incra Mast-R-Lift, Rockler SL
These lifts boast beefy plates and extra bells, yet they need a fresh top with the larger standard opening.
If you crave that path, bolt a new top to your stand and slide the Bosch fence over.
Install Walk-Through From Empty Opening to First Cut
Tools on hand
Straightedge, small square, tape, pencil, corded drill, countersink, step bit, hex keys, flat file, shop vac, thread locker, and a calm playlist.
1. Clear the Deck
Unplug the table.
Pop out the stock plate.
Dust the ledge so no chip hides under a corner.
2. Dry Fit the Plate
Set the new plate in place with no screws.
Check flush with a straightedge.
If one side sits high, back off the cam wheel or leveling screw.
3. Mount the Motor
Pull the fixed base.
Wipe the aluminum body.
Slide the motor into the lift carriage until the shoulder kisses the stop.
Tighten bolts in a star pattern.
A drop of thread locker keeps them from walking loose later.
4. Level the Plate
Turn each corner screw until the surface meets the straightedge.
Run a scrap across the seam.
Feel with your fingers.
Your skin tells the truth.
5. Drill the Crank Hole
Place the template if the lift comes with one.
Use a step bit so the hole edges stay clean.
Deburr top and bottom with the file.
6. Zero the Dial
Insert a straight bit.
Raise until it just kisses a setup block.
Spin the index ring to zero.
Write common moves on tape stuck to the fence face.
Now fire the switch and take a shallow pass in scrap.
Feel how steady the motor stays.
Smile a little.
Tips That Save Time and Wood
- Keep a scrap of hardwood that rides the plate seam; any lip means adjust.
- A light wipe of dry polytetrafluoroethylene on the lead screw blocks dust buildup.
- Store insert rings on a peg at eye level so you swap fast.
- Set fence first, then sneak height, never the other way around, it cuts setup time.
Joinery Examples That Prove the Lift Pays
Picture a stack of stile blanks ready for cope cuts.
Set the bit height once, lock, cut every end, they match.
Next day you cut rail cheeks on a sled.
Half turn up, lock, push, perfect.
Need grooves for floating panels?
First pass sits shallow.
Quarter turn down, final depth done.
You waste no test pieces.
Clean Edge Profiles Without Burn
Round overs shine when height is spot on.
Raise the bit until the bearing just kisses the face.
Lock.
Run every edge.
Not one burn line shows, because the motor never droops mid-run.
Multi-step crown molding bits also behave.
Start one pass light.
Crank the last hair for the final sweep.
Surface stays glassy.
Care and Feed for Long Life
Dust is the enemy, not wear.
Each session end, brush lead screw threads, vacuum, done.
Once a month, add one drop of dry lube on the screw, run the carriage up and down, wipe off extra.
Check clamp bolts at the same time.
They may settle in the first few weeks.
Confirm plate flatness with a straightedge at every season change.
A quarter turn here or there keeps it perfect.
Common Hiccups and Quick Fixes
| Symptom | Fix |
|---|---|
| One corner sits proud | Back off that corner screw, snug the opposite side |
| Height drifts | Tighten lock lever another notch |
| Dial mark shifts over days | Check that insert ring is seated tight |
| Fence seems off center | Align using etched center lines on the plate |
Fast Answers to Ongoing Questions
Will a JessEm lift really fit the Bosch RA1181?

A Quick Story From My Bench
I built a white oak vanity last spring.
The frames needed perfect cope and stick joints.
I set zero on the dial, made a test cut, raised two full turns, cut again, fit like a glove.
A week later a spare rail was needed.
I dialed the same two turns, the fresh piece fit the old mortise with no tweaks.
That tiny dial saved me from a rerun of the whole setup.
