Roll Pin Removal?

Hi,
Have another question for the experts. When you raise the tubes to a vertical position it pivots on a shaft. In the end of this shaft appears to be a roll pin. If I read correctly this pin is removed by driving completely through. This pin is rusted so before I start driving I want to be sure this is correct. Is this correct and is there an easy way, proper position or just lube it up and go for it?

Thanks in advance,
Doug

Get the right size pin punch before you start trying to drive that roll pin out. If you mess it up, you may never get it out.

I'd tell you what size to use but I don't know and I don't have one I can measure.

Dusty,
Thanks for the quick reply. NEVER sure is a long time. You sure give a fellow a lot of confidence:D

Thanks
Doug

No expert yet, but I did what you are doing just last week with a rusty pin. I sprayed some PB Blaster in there and let it sit for a little bit, then used a hammer and punch. Be sure you watch where the pin lands as mine hit the floor and I had to completely clear out my shop to find it.

I just looked and it was a 5/32 punch that I used.

When I was restoring my Mark 5, I didn't have a pin punch, or a punch of any kind. I used a nail as a punch. Actually, I used several nails because they kept bending. When one bent too much, I threw it away and grabbed another one. I just kept going like that until the roll pin was out. I used a little bit of Kroil penetrating oil first.

Pin is in hand. Shaft and pin are clean. Now for the legs and casters. UPS delivered a new to me set tubes today also. Look great. May get everything clean and start putting back together in a few days.
Thanks for all the help

GOOD. That was the reaction I wanted. Believe me, if you mess that pin up you may never get it out. This is one time where you tap it out. You do not drive it out. Finesse. Tap, tap, finesse, tap, tap, finesse, tap, tap, success.

How likely are you to mess up the roll pin? Aren't they made out of hardened steel? I'm definitely not saying you're wrong, but I didn't "finesse" any of the ones I removed and there was never a mark on them. They were certainly harder than the nails I was using to drive them out. I was more concerned with messing up the lock knobs and such that I was driving the roll pins out of rather than the roll pins themselves.

I'm not arguing. I'm just stating an opinion based on experience. But if you spread that roll pin or mushroom the end of that roll pin...it is all over. You can not get to the other end to drive it back.

I did mushroom one pin once.

I just ground off the mushroom and out a slight taper on it using a strip sander and it went back in with about the same effort as the others.

Just offering a work around.

The correct size punch is much better advice and a much better solution.
