I was asked by a lady to provide her with the two 20" tubes for a lathe extension for the ER.

Here's my issue. Should I cut the two tubes from 1 way tube leaving me a 12" section? Or should I cut 20" off two tubes leaving me a pair of 32" tubes?

I could use a shorty ER. But looking at past posts it's generally agreed that 32" is to short for a Mark V. I couldn't find any shorty ER posts.

I have both the "A" and "B" SPT adapters and want to still use them. I also want a reasonable drill press.

Has anyone done a shorty ER? What's your advice on tube length?

Why do I want a shorty? I have a very small shop. My cheap HF drill press is shot and I want a more accurate one. I never turned a spindle, only bowls. My ER is almost always used as a table saw but have never needed the entire width of the machine.

Any thoughts or has anyone done a shorty ER?

If anything, the ER has need for more 'length' than the MV because the tubes need that extra length sticking out for attaching tail stock and aux tables and adapters.

I will not at this time go into my mantra re cutting "10" tubes.

Hi Tom.

In the Photo section on the 10ERusers Yahoo group there is an album showing a 30" shorty.
https://groups.yahoo.com/neo/groups/Sho ... /314755240

It looks like he had to modify the pivot base, and he also has a second carriage that has been cut down to make the drill press mode work.

A couple of things to keep in mind regarding the lathe extension.

- towards the end of the 10ER production they changed to thinner walled way tubes (the same as are used on the Mark 5/V's), so you will need to know which tubes
the customers 10ER has to make the adapter plugs the right size.

- the flip side of that fact is that you could use Mark 5/V tubes to make the lathe extension.

It seams to me that the reason we make shorties is to create a specialty station and drive SPT's in a smaller foot print. To me it doesn't make much sense to make a 10ER shorty unless you have the "A" and "B" adapters as you have.

JPG and Ron eluded to it and I will echo it. Please do not cut 10ER thick wall tubes. They don't make them any more so the supply is limited. Even if you have original thin wall 10ER tubes I would hesitate to cut them . I would get MK V tubes and cut them. They will work just fine.

As requested by Tom in a PM, here is a picture of Dave Eatwell's 10ER Shorty with 30" tubes that was posted on the Yahoo group.
I have collected all of the photos he posted and the text of the associated thread into a .pdf file. it can be downloaded from this link.

Interesting but that is a lot of hacking for just a few more inches of height on the drill press. Perhaps the 30" should be 34"?

Anyway thanks for sharing that, too bad we could get a few more of those people to come over here to the forum to share on an on going basis.

I agree. I am not sure why one would want to do that.

I suspect the 30" came from only having to cut one way tube in half.

I was just checking and Dave Eatwell left the Yahoo group back in 2013

If Tom (aka Hog Winslow) makes a 20" lathe extension for his customer, then he can make his Shorty 40" long. That would probably negate the need for modifying the pivot base and cutting down the second carriage, and should also leave room for a speed changer, which the 30" model doesn't seem to have room for.

Apparently it was made to a customers specifications for doing small work.

Hi Tom,
Which way is she going to make the extension? I'm just curious. I have seen an extension on a second short bench (first picture) using a base and arm to mount it with sleeves over the tubes. This way it wouldn't matter which thickness the tubes are. The other way (second Picture) was inserts in the tubes connecting them to extend from the existing tubes with a tie bar for the "floating" end to attach the tailstock. Although the original used the same thickness tubes, this could also use thin wall to thick wall tubes if the sleeves are machined to fit each tube end. That would also save on weight hanging out past the base end. Either way the extension has to be "locked" to the Model 10 somehow.

As for making a 10ER shorty, play around with the parts on a standard length Model 10 to see what length would work for your needs. Unbolt the headrest to move it and the other parts closer to see what works. If you cut 20" off either Model 10 or Mark V way tubes you'll be down to 32" left. I'm not sure where the 60" way tube length came from. Both the Model 10's and Mark 5/V's are 52". Even the Mark V bench tubes are not that long.

P.S. Haven't talked for a while, hope all is well with you.

I turned mine in to a dedicated sanding station. I can use the saw if I want but to be honest, I never liked the shop smith table saw.
