My apology for accusation

stable???

With the power head adjusted 10 in from the top. The top to right & left tip is 14.5 lbs. the top to back tip is 12 lbs the TTF is 23 lbs. On my 520 the right tip is 12.5 lbs the left tip is 8.2 lbs I don't understand the difference.
My neighbor has a Central Machinery floor drill press the R & L tip is approx 11 lbs. the TTB tip is 9 lbs the TTF is off a 30 lb scale. So to answer the question. it"s more stable than Central Machinery .

Sorry I misremembered where I saw the post. But thanks for the inspiration, I think.

Jerry and Glenn, nice dedicated drill press! Is the basic process to remove the headstock, then disassemble everything, cut the bench tubes then put it all back together? I'm thinking of doing the same but I will leave the bench tubes a foot longer. Also, I assume it is no longer possible to put the dedicated press in horizontal drilling mode after the surgery. This is not an issue for me, just curious. Thanks for your help.

Look closer!!!! The headstock is reversed on the way tubes(as is the carriage/table). i.e. if 'lowered' to horizontal, the headstock and table would be upside down and under the way tubes.

Not very useful there!:D

Key word is 'dedicated'.

Based on other conversions I've seen I was thinking of having my headstock and table face outward rather than inward. Might need some ballast across the bench tubes for stability against tipping forward. I think then I could possibly still lay it down for horizontal boring. But with the way tubes longer than the bench tubes, well I guess I won't really know till I play around with it.

As I understand it the bench tubes are different sizes for different year models so I am addressing my 1954 SS only. The base will accept up to 2in dia tubes. So I scrounged a length of 1 1/2 inside dia black iron pipe from the junk pile in back of a local pluming shop. The pipe has a OD dia of 1.9XX in. The original bench tubes have a dia of 1.7XX in. I considered putting it together with the head stock installed in the conventional configuration but I always had a problem with the table and way tube flex on my 520. Besides if I need the extra length for drilling I can always use my trusty SS 520. For horizontal boring I feel the 520 table has more hold down options because of the "T" track the 1954 table does not have these options.

There are flat spots on the under side of the main that will accommodate the aux table brace. The length of the bench tubes was determined by the placement of the table brace on the main table flat spots.

As a note: The way the bench tube clamps and mating surface are designed I think something less than 1.7XX dia tubes can be used.

Works for a Model 10, but not for a M5/V/7.

There have been two different bench tube sizes. Early greenies had 1 7/8" od tubes and larger holes in the end castings. More recently they have all been 1 3/4". The id has varied from the robust 10E/R to thinner walls on newer models. All way tubes have been 1 3/4" od.

I made an ER lathe way extension set-up, by cutting the 2X6 bench boards, so that the Shopsmith ER leg braces met in the middle. The only ER part I had to change, was to drill out the threads in the center of an ER tie-bar. Only thing mounted on the shortened base, a pivot base, way tubes, tailstock mounted loose, carriage, and a tiebar at the top end. A tailstock knurled screw will attach the extension to my regular ER, with another tailstock mounted over the gap, to align the rig. Gives me over 7 feet by 15 inches, of spindle capacity.

I'll do the same thing, except put a headstock and motor on it, for a dedicated drill-press.

I'm thinking of using my last ER to make a faceplate lathe, with the headstock backwards, hanging over the left end of a shortened base. That one "MAY" have shortened way tubes.

I can see why you all have no "issues" about cutting Mk-X way tubes, they're still printing them. they haven't made way tubes for MY stuff, since Harry Truman was in office. (And, my ER tubes are {almost} 1/4 wall thickness.) Find that on a Mk-Whatever.

I consider cutting 10E/R tubes a cardinal sin!!!!!:eek:
