3" caster upgrade

Re: 3" caster upgrade
The 3" wheel radius minus the original wheel radius? Yes, I know the geometry of the wheel hardware means that is probably not correct. So, the actual off set would be nice to know.

If SS had included dimensions this problem would have been averted.jsburger wrote: ↑Wed Jan 11, 2023 4:05 pmI had a discussion about this with Mike Young years ago. The original paper templates were correct. At some point they started reproducing them on an in house copy machine. That changed the size of the templet making the dimensions incorrect. The correction was the metal templet.

Re: 3" caster upgrade
I consider the offset to be 1 3/4". Offset being defined as the distance from factory location of a hole to the location of that same hole after the upgrade. Offset being measured along the centerline drawn through the mounting holes (on the angle of the leg). I said 1 3/4" (aka 1 23/32 on the drawing).

Re: 3" caster upgrade
The SS legs are a fairly organic shape so, measuring from what to where and at what angle might be a challenge for some users.dusty wrote: ↑Wed Jan 11, 2023 7:06 pmIf SS had included dimensions this problem would have been averted.jsburger wrote: ↑Wed Jan 11, 2023 4:05 pmI had a discussion about this with Mike Young years ago.

Re: 3" caster upgrade
The template should be easy to measure.
On the legs, measure along the center line of the holes.

Re: 3" caster upgrade
Tis more complicated than that. More than the wheel diameter changed. The caster stem and cage and axle etc. also affect this. Maybe you just said that by referring to geometry. Also the hole's center line is skewed from vertical.

Re: 3" caster upgrade
Dusty,
As always, a great drawing. Your drawing replicated the SS template. I wasn't sure why you were getting 1-9/16" but from your drawing I see that is the actual height change while accounting for the angle. 1-23/32" is the distance between the original holes and the new ones for the 3" casters on both the paper template and metal drill guide I have.
As for drilling the holes slightly higher, personally I would not. I don't believe you would gain any additional stability by having the wheels even higher off the ground when the Retractable Castor assembly lowers the bench legs to the ground. Doing so would result in less clearance when the bench legs are moved off the ground. When the bench legs are lowered to the ground there is just enough clearance on mine to rotate the wheels by hand.

Re: 3" caster upgrade
I agree wholeheartedly that when the wheels are up the machine must rest FIRMLY on the ground. Obviously, to far up voids the lift and thus the purpose of thr wheels. Strike a happy midground..chapmanruss wrote: ↑Thu Jan 12, 2023 11:30 am Dusty,

Re: 3" caster upgrade
Dusty,
Just an fyi...but the SS premium casters have quite a bit of play in them. For example when I checked mine yesterday, yes mine are firmly resting on the ground BUT there is no weight on them. I could easily push on the wheel to "cant" them inwards because the swivel mechanism allows this. I am just pointing this out that straight vertical measurements here will only get you so far because the casters when not bearing a load can deviate off of the vertical axis quite a bit. In other words, this may or may to be accounted for in your measurements/drawing. Until there is some preload on the casters, the casters have quite a bit of side-to-side play but can still be firmly on the ground, yet not bearing any of the Mark V load.
