How to use the microadjustment

Note: To have a better understanding of this technique, you might want to check the modifications that we made to the endstops.

  1. With the swivel hard against the stop, set the stop to a dimension that's smaller than the nominal dimension by an amount that you think is suitable (E.g. how much macro-adjustment you need).
  2. Back the swivel paying attention to the gauge on the micro-adjustment knob and go pass the nominal dimension.
  3. Take a cut, measure using the method of your preference and adjust accordingly.
Recommended The saw is loud, we recommend hearing protection.
Mandatory Please wear goggles or a face shield
Recommended We recommend the use of a respirator
Recommended Use all available guards

Date Description Workaround Proposed Remediation
- Blade change pin bending over time Still works until it breaks Lathe replacement from tool steel
- Blade plate is slowly deforming Still works Manufacturer replacement or cnc replacement
- Sliding fence has slop at main pivot being loose in extrusion Saw has to be manually tuned with 5 cut method for high accuracy cuts. Machine uhmw spacer to reduce slop
- Blade guard damaged by reseller demonstration, design deemed unsafe due to catching material. Blade guard removed New guard to be CAD and laser cut
- Slide is not smooth operating - -
- Sliding fence angle gauge stickers worn off Measure angle manually with other tools Replacements CAD and laser cut/etched in <1mm stainless steel
- Arbour thread is not clean and hard to manage - -
- Rise and fall lock never worked lever removed -
- Scribing blade bearing is totally seized, stopping the saw operating Part is currently removed needs new bearing or total manufacturer part replacement
- People treat the handles that secure the sliding table to the machine as adjustable points when trying to operate the machine. This results in the sliding table becoming uncalibrated. none Replace handles with bolts
Date Modified By Description Remediation Cost
- Joshua H Rise/fall and angle handles fell apart machined some adapters and used a surpus handle from the A331 <$5
- Joshua H Ratcheting handles that secure the sliding table extension broke replaced by better ones from ebay ~$40
- Joshua H Angle indication on front inaccurate shimmed with washers to be accurate -
- Joshua H Screw for changing scribing blade height was inappropriate and crashing with table surface, and wearing due to flathead design. Replaced with appropriate grub screw <$5
- Joshua H 90º fence stop for sliding table fence deemed unusable replacement mechanism designed in CAD, machined by members and installed. -
- Craig Hudson Riving knife always higher than blade, stopping joinery cuts. Riving knife modified to allow for correct height for joinery -
- Joshua H Sliding table fence scale hard to make accurate Stop at end of sliding table fence replaced with wooden block tuned to make the scale on fence accurate -
- Joshua H Sliding table fence angle lock bolt stretched and worn by overtightening replaced by parts from jig kit -
- Joshua H Sliding table clamp post unhardened and raising burrs part hardened by forge cause -
- Joshua H & Ian Redmond Rise and fall gear/worm totally worn and failed. Replacement parts ordered but incorrect due to machine revision. Fix found by rotating gear 180º to unworn section ~$150
- Ryan Marple & Ale Moré Rise and fall gear/worm totally worn and failed. Parts were milled, specifically, holes were slotted to allow the installation of a different size worm wheel. -
14/02/2021 Ryan Marple & Ale Moré The stops couldn't be calibrated with ease Crosscut endstops were modified with an adjustable bullseye -
15/01/2022 Ale Moré Planned maintenance Change the arbour bearings

The crosscut fence stops have been modified to be more accurate and easily corrected if needed. By design, the modification doesn't take into account any adjustments you make using the micro-adjustment. In other words, the bullseye is 100% accurate only when the swivel arm is hard against the fixed part of the stop. Having said that, it doesn't mean that you can't use the micro-adjustment, you just need to plan ahead (which is commonly the case with micro-adjustments).
