Table Crank Retrofit for Delta Rockwell DP

Rate this topic

Recommended Posts

Does anyone have a good source for a mechanism that will raise and lower the table on my Rockwell Delta DP. A hand crank? Right now I have nothing, but a sore back by lifting the table by hand. I have literally almost blown my back out by forcing that table up by twisting and raising it by hand, I need a crank. Or a new DP, and I am not ready to fork those bucks out, plus I like my ol DP!

John,I rigged up a scissor jack on the one I had before and on this one I have a HF Electric trailer hitch jack, but it is 12v. so have to have a battery and trickle charger.

I know what you mean ,they are back killers.

Herb, I am sorry, I am having a hard time envisioning a scissor jack, is the jack resting on a platform raised off of the base?

Yes,I made a platform box to set on the base, then set the scissor jack on that ,I had to make up a wooden plate to flatten out the bottom of the upper table because of the cast iron ribs etc.for the jack to lift on. I also found that the jack has to be mounted tight against the column,sideways,  as it binds the table when raising and lowering, and I had to apply hand pressure down on the front lip of the table when raising and up on the front lip when lowering.

 

To eliminate the binding on your table you might consider attaching a cleat under your existing table to cantilever a small platform to the rear of your table to add some weights to counter balance the weight of the table.

 

I put a hand wheel crank on the jack to raise and lower it. Hope this helps.

 

The electric trailer hitch jack is taller and I don't have as much height adjustment as i would like. I use the battery to counter balance the table.

It is a vintage WWII  Atlas. I love it, it has a 4 1/2" quill travel. I did a thread on this forum awhile back on refurbishing it.

 

If you use a scissor Jack, you might be able to rig up an old drill motor to raise and lower the jack.

Just saying.

another option i have seen is using a weight (counter-weight) and a cable and pulley to essentially "remove" the weight of the table from the equation; making it very easy to raise and lower the table and then lock it in position.

@John Morris...late getting to this party but your request challenged me because both my late 60's Craftsman and early 40's Atlas drill presses both need something too. @Dadio's idea and creation is awesome but me being the scrapper and tightwad I am, kept me looking and thinking...just hadn't followed through on anything yet...you motivated me to do a little looking so I found these two ideas worth considering. I really like the 2nd link idea and may consider some variation of that as my first option.

Operation Ward 57 Challenge Coin Display Project

We are a woodworking community with an emphasis on sharing and learning the skilled craft of woodworking and all of its related disciplines. Our community is open to everyone who wishes to join us. We support our American veterans and active duty, being a veteran is not a prerequisite to join. Join us now!

Objective

Air Force Command Center Plaque

Of course just like most online woodworking communities we are centralized in the arts, crafts, and trades that are woodworking. But, we have another focus in our Patriot Woodworker community, we are the only woodworking community that was founded on our care and concern for our disabled veterans.

Volunteer

Patriot Woodworker Volunteers

The Patriot Woodworkers are an all volunteer community, from the staff and hosts who run our online woodworking community to the members who frequent our forums, you'll find volunteers in all of us. We are not on a payroll, unless you consider the spiritual rewards gained from volunteering, as compensation.

Education

Logging

One of the many projects we are working on is a wiki for our online community. A wiki is a great way for woodworkers and enthusiasts to share their knowledge to others, and to impart their knowledge for others to learn from, and utilize as well for their own benefit. We hope you'll consider being a wiki contributor.
