Walker Turner Drill Press - Speed Chart

[freebo86]

So I've rebuilt my Walker Turner Drill press over the last month. Unfortunately the unit did not come with the top cover that covers the pulley or the 3rd (slow speed) pulley.

I am in the process of fabricating something to make my own 3rd pulley but was looking around and I see most drills have a speed chart that shows the belt setup and what RPM that achieves.

Ideally I'd like to produce something similar and print out however no idea where this was once on this Walker Turner press. Typically these are on the pulley covers but looking at pictures online of the Walker Turner presses the way the cover is shaped I don't think that was ever the case.

Anyone have suggestions where to stick this chart to? Or if someone has the original chart what it looks like that would be even better!

Sorry, should have stated this in the original post. Its a 1-944. Guess its the WT-900 series, floor model which I believe is the 20" model.

900 series is 15". Do you have the slo speed attachment?

Photos?

Unfortunately the press did not come with the slow speed attachment. It came with foot control attachments though (which I have no use for). See link for Google Photos Album of my restoration of it. The wiring was pretty messed up so I replaced that and cleaned and greased all parts. Installed new proper 3 prong plug as the original was completely busted up and also had to install a new ON/OFF switch. The drill press base was also replaced by someone over the years by a base marked "Canadian Blower and Forge", the base is massive.

I would like to make my own slow speed attachment but struggling to understand on where to install the bearings for the pulley rod. The pulleys I've sourced locally come with a 5/8's bore which is way to small to house a bearing within the bore. I guess thats something that perhaps the Garage Journal community can shed some light on!

There is calculators online to determine the bit RPM speed by knowing the pulley sizes, motor speed etc. so I can figure those out fairly simply. Its really coming up with the slow speed attachment.

This might be a good place to start.

Back to your original question. They never had a chart. I would simply make a copy of the belt arrangements from the manual and hang it on the machine.

An alternative to a slow speed attachment is adding a VFD. When I restored my WT900, I used a 220v, 3/4 hp, 3 phase motor and a basic VFD. Even at low speed, the larger motor provides plenty of torque. It provides infinite speed adjustment on 110v house current. I'm very happy with it.

Think I saw your picture in one of the other threads I was reading and appreciate the input. I would rather stay away from a VFD and having to change the motor out.

There is local pullies that are <$20, based on calculations I should be able to get down to 270-280 rpm with this. But the bearing issue comes into play.

I saw a slow speed attachment on eBay today and they show up from time to time. You could scoop that up or make notes on it and try to fabricate one.

As for the tag, WT did have one for slow speed attachments. It went on the top belt cover. Picture is below.
