Pin into lower triple style, like the last one.

I got one from Lockhart-Phillips.

+1 on last one.

Pin in triple you can do fork work  Also, IMO, more stable.

The under the fork end style make me very nervous.
Even on a lift where there's a wheel clamp holding the rear.
Too many degrees of freedom, and falling off a stand is a calamity

If you have a *secure* way of holding the rear
Two jackstands and a piece of pipe and a scrap of hose
Raise front with dodgy under-fork stands
Pipe under H cylinder with hose as a pad, supported each side on a jackstand
Remove dodgy under-fork stands
Commence fork work

Awesome
Thanks guys, do any that you know of have a 7mm pin. Aftermarket trees

You might check T-Rex: https://www.t-rex-racing.com/Triple-Tree-Stands-s/439.htm

You can buy individual pins and swap them out for whichever bike. Not sure how their measurements work, though.

7mm pin?

Got a picture of the bottom of your stem?
Title: Re: Front paddock stands
Post by: Pinion on April 11, 2020, 10:39:27 AM
13mm is the smallest pin i can find

I don't remember the size pins on the Pit Bull I had,  but way bigger than 7mm.  What lower triple is that?
Title: Re: Front paddock stands
Post by: Pinion on April 11, 2020, 11:36:56 AM
AEM
It's an 8mm hole
Might just go with the one with pins in the bottom of the forks
Title: Re: Front paddock stands
Post by: Speeddog on April 11, 2020, 11:43:30 AM
Yeah, you gotta go fork bottom style
Title: Re: Front paddock stands
Post by: Pinion on April 11, 2020, 11:49:33 AM
I'm gonna confirm the lightech span, I like it because it's fixed with pins in the bottom
I can just use my bursig if I need to deal with fork work

Why not have a pin custom turned?

Was thinking of that too
Like the idea of the tree stand
Not a fan of the bursig is stand either. Always in the way

IME anything less than 3/4" pin will bend on an under-triple stand

You may very well be correct, but T-rex sells a 12 mm pin.
Title: Re: Front paddock stands
Post by: Pinion on April 11, 2020, 04:02:03 PM
12mm is close to 1/2”
8mm is less then 3/8”
It will not be strong by any means,
Not sure how much the pin is used for,lift as is stability
Title: Re: Front paddock stands
Post by: Speeddog on April 11, 2020, 06:13:08 PM
I made a pin from a 12mm or 1/2" bolt, cant remember which.
It bent.
Not a 12.9 or grade 8 bolt, but not crapola.
Title: Re: Front paddock stands
Post by: ducpainter on April 11, 2020, 06:16:16 PM
OK...so why not bore out the stem?
Title: Re: Front paddock stands
Post by: Pinion on April 12, 2020, 03:17:48 AM
That, I think I would very away from. Things are made a way for a reason.
Hmmmmm......... paddock stand I want vs life, that is a hard one

That's pretty dramatic. [roll]

The Ducati stem has a big honking hole, and it's perfectly safe.

Some things are the way they are for no good reason at all.

Is the fancy stem thick alloy Vs a hollow steel tube?
Title: Re: Front paddock stands

Get a pin turned out of cold rolled steel and post photos of results!

I had to do the same thing for my previous S2R (don't have a new triple tree stand yet).  Worked out well!  Granted, I was going bigger instead of smaller....drew it up in Fusion 360 and had a friend of my father in law fab it.

I was actually thinking titanium
I think anything that's not cast might work
Title: Re: Front paddock stands
Post by: Howie on April 12, 2020, 04:47:14 AM
Keep in mind the stress on the pin is on the way up and down.  Speeddog's 12mm. bent and 8mm. is a lot smaller.

Yes
Also consider cast is much weaker then rolled, titanium has higher stress values
Honestly if you consider using a valve, nipping it off and drill out a receiver
I have used a valve out of a 350 to adjust coil over compression on off road truck on the trail

I think we need to send this to This Old Tony and see a pin made.

Here's my 2 cents since I use the last front lift in your original post; the pin question aside, I've used the lower section with a 1/2" dia. x 2' piece of solid mild steel rod through the front wheel spindle and same way on the rear SSS also for more stability; is doesn't allow for wheel work like that; but is more stable than the pin.

With the pin its less stable, and note; the stand can rotate if you not watching it all the time; as it did on me once, while I was working on the front breaks; I caught it as she went over on top of me; but had momentum and weight as it went down gently on top of me got a little pinned and squished and wrenched my back trying to stop it. I believe they recommend using a back stand to help stabilize and I have used the same rod with jack stands on the rear and front triple pinned. Also its nice that with the pin you can remove the front wheel.

I think the under triple stands for the bikes with adjustable steering stems hooks the lower triple.
