Power Rack

[harlequin]

Hi,

I'm going through the process of building up the power rack as detailed in SS, just wondering if you can enlighten me...The bolts you use - can't get them.

Did find some suitable 35mm steel in the rack at college made a set of pins. With the bolts do you put a nut on the back end, or are you relying on the length sitting through the c channel to prevent the pin slipping when lifting the weight on and off?

ta for any info

I can get them. Why can't you? They are held in place with a nut. There is a picture on the pdf: http://startingstrength.com/files/po...n_rippetoe.pdf

I could order them through the local hardware shops, but because I live in rural australia we don't have a decent range of imperial and the price is ridiculous.

I made my own as scrap steel as it doesn't take much to make two pins, well not when tacked on to building a rack - feel free to read that as I'm too cheap to buy something when I can make it.

Is there any reason why the top bar is reduced in size down to 1 inch to go through the channel?

The bolt sizes appear to be different between the pdf and the drawing in the 3rd edition - please note I can't read imperial sizes to save myself I live in metric land.

The top bar is necked down to fit through a hole in the channel, which has 1.5 inch OD sides, less the thickness of the face. I don't see the bolt dimensions on the PDF. But I can help you read it.

It is a SIX INCH LONG AND ONE AND ONE-EIGHTHS INCHES IN DIAMETER BOLT. WITH A NUT THAT FITS IT.

Hope that helps.

I found some and I live in rural WA. Or was. Price was something like $20 at most.

The bolt needs a shank that's 50 mm long and the diameter needs to be whatever you drilled the holes, I used 30 mm rod. The rest is irrelevant.

In other words,mate, 150 mm long bolt and either a 28mm or 29 mm bolt as the 1.5" falls at ~28.5 mm

Rip,

Is the updated drawing ready?

There has to be enough slop in the hole diameter that the pins can drop two holes from front to back.

Rip,

Not yet. I will prod him when I get back.

I forgot about that. It was a while ago. IIRC I drilled my holes 31 or 32 mm. 32 I think.
