Clausing 8520 Riser Block Help

[opsoff1]

I am (attempting to) fabricate a column riser for a Clausing 8520 series mill. Trying to duplicate the riser made by Bill Gruby & Joeuser01 in this thread; Riser Block. I posted this on the WTB section, but thought I would duplicate it here too - Looking for a 4-5" long section of pipe - probably DOM, not sure of the alloy - but looking to weld it to A36.


TIA

This place has 1020 DOM Tubing in various sizes and should work good for your application: https://www.metalsdepot.com/steel-products/steel-round-tube-dom

There are a lot of DOM tubing suppliers nationwide, so look around.

Appreciate the lead - I checked on pricing for the 6" OD x .50" wall at 4" long - $192. + shipping. Trying to get out of this a little cheaper.
Probably need to haunt some shops for drops.

Could you perhaps cut up pieces of your plate to make a welded up hexagonal or octagonal riser?

A square (basically) would work also - just a different method - may be worth pursuing vs trying to source that size of pipe.

I looked at that - is that type of pipe/wall thickness strong/rigid enough for the application? Wall thickness is .280 and no idea what type of steel it is.

Have not used it in that type of application as of yet, so I could not say.

I have, however, made a Machining fixture for a H-53 rotor guide that used 3/4 × 2 x 16" long steel flat stock, pin aligned in place, then welded to 18" diameter by 1" thick rings for reworking. Worked out Great! Just thinking. Sizes are approximations, as I have the particulars in a notebook.

Perhaps something like these used up 4 inch wide cast / semi-steel stand up forklift load wheels would work? Do you have a local salvage /scrap yard?
