I tried the Rollie's Dad Method to check spindle alignment, and fully extended the ram of the tailstock to check angular/horizontal alignment. Spindle vertical...
WOW!!! Thanks for all of the responses! I've tried a few things to attempt to make this work. I played with the 3 pots at the board. The middle pot seemed...

Does anyone have any extra acetal lying around that they want to get rid of? I figured I would ask before ordering any. I am looking for anything from...
I made a pair of cylinder squares per an article in HSM from years ago. When I was checking the squareness, I found my "Import" "machinists squares" I had bot...
I need to build some folding ramps for my trailer. The trailer is for transporting my tractor. My tractor weighs 4500 lbs. The gross weight of the trailer will...
I don't know the formulae, either. Is something found in a calculus book, I'm sure. Look under caternaries. Your weak point here in this plan is your...
Are you proposing to have a 36" axle made out of 1.25" steel rod, supported at each end? And then mount two 14" sleeves on it, each of which will take one ramp...
That's actually quite good. To fix it, you generally shim the back. Also, make sure the quill is allignened translationally (or whaterver) wit the headstock....

I am not sure if I understand the question fully. if you have a folding ramp. one section overlays the other and is of heavy stock, the force on the pivot...
If you build them like car ramps In a triangle fashion your pipe will be fine. My trailer has 1/2" solid rod with dom tube for the pivot. I have loaded a...

One trick I notice ramps for dozers use is to have legs that extend from nearly at the hinge to the ground when down. That way, when the trailer "sits down"...
A simple calculation for deflection of a 36" x 1.25" steel bar with 2500 lb load in the centre suggests about 0.63" deflection if the ends are free, and about...
Hi James, Just out of curiosity, what kind of trailer is it? Is it double axle? I have a 5000 lb. machine tool I need to get a trailer for. I haven't reviewed...
Sorry I meant fold up ramps. Not folding ramps. ... From: dave_mucha To: 7x10minilathe@yahoogroups.com Sent: Monday, January 02, 2012 7:35 PM Subject:...
This will be part of the design. The triangle will also act as a truss for the ramp as well. The problem comes when the ground is either not firm or the...
I think it does. Since that does not include the 14" section of tube. Could you do the same calc with a 22" length of 1.25" steel. I would think considering...
JB, It is a home made job. I stripped a 26' camper off the trailer. Shortened it to have an 18' bed. Then added some additional cross supports. James ... From:...
