Delta 700 Scroll Saw Restoration, and Upgrade

Rate this topic

Recommended Posts

Thanks for the comments everyone, and sorry for the delay in getting this finished.

 

I've been dealing with a case of the creapy crud (cold with flu like symptoms) for the better part of a week now.

So when I feel more up to it I'll be sure to "getter done" and give what will be close to the final update of progress.

Hi everyone,

 

It's been awhile since I last did an update on this, so here we go.

 

I had put this on hold while I determined which side to mount the drive on. I have came to the conclusion that it will be mounted as it is now. Due to a surprise aquisition offered by a member here (my heartfelt thanks go out to him) it will be mounted back to back with the bandsaw that compliments this scroll saw.

I will be mounting both on a later model scroll saw stand that I will be putting a wood top on to make it long enough for both saws.

 

So when I get the stand stripped, painted, and the wood top on, it will be time for a test flight of the 700 scroll saw. I'll be posting pictures as work progresses.

As always I am impressed with the work you guys do with these older machines. I just love watching this stuff take place. Wish I had the extra room, I would definitely get involved with this.

Larry -

 

 

That's some very nice work. It looks like you had a few pieces that were pretty rough when you started out.

Were you able to salvage most of it or did you need to remake some of the parts?

That's a beautiful looking saw.

Randy,

 

The saw is a combination of parts from two 700's, plus parts from later model Delta saws. Some of the parts were made from scratch so I could adapt the later model parts to the 700. I used as many original parts as I could. Both saws were pretty rough, I used the best parts from each of them.

Thanks Shane,

 

This saw was my first restoration, and I think it came out rather well myself.

 

 

I'll be using the same color scheme for all of my " Old Delta's ", It was your Universal Woodworker restoration post that inspired the color scheme! I think it looks great on these smaller machines.

Hi Larry

 

I have just bought a Delta scroll saw,looks very similar to yours( great job by the way) and no sooner do i get it off my truck and put it in my garage that the upper chuck busted on it. I was wondering were would i find an upper chuck for my Delta?  If you could help me out i would greatly appreciate it.

 

 

Thanks very much,

 

 

 

Benjamin

Hi Benjamin,

 

Ouch!

 

 

I looked for better than five years to find a good upper chuck for my 700.

Almost all of the 700's I've ran accross have the upper chuck broken or missing.

They do turn up on ebay once in a while, usually as the complete plunger assembly with the head casting.

The ones I've seen went for more than I paid for both of the saws I started with.

The chucks on these machines are made out of cast Zamak, which is a type of pot metal.

Original replacements have not been available from Delta since the early 1960's.

I believe the last catalog listing was 1962.

I tried posting wanted to buy listings on other websites without success.

There is a product called Muggy Weld that others have used to weld cast Zamak parts with.

It is similar to brazing but requires less heat.

Sorry I can't be of more help.

Benjamin,

 

It may be possible to use the lower chuck from a later model 1200/1440 saw to replace the upper chuck.

They are a direct replacement for the lower chuck.

As you know both the upper, and lower plunger tubes are round on the 700, I would have to check if they are the same size.

I got the lower one I used for about $12.00 plus shipping on ebay.

The upper plunger parts I used came in a box of miscellanious parts I picked up somewhere along the way.

It would require adding a washer, and the indexing pin to accomplish the blade indexing.

Otherwise you could do like I did using the parts from the later style upper plunger assembly.

Having a machinest friend would make turning the later style bronze bushing down much easier than turning it down by hand, like I did. Much quicker also.

Ted,

 

Are you missing the plunger, or the piston disc?

Heres a few links to the manual.

The manuals are from different dates.

Ted,

 

I thought I had a spare, but can't find it at the moment.

So I pulled the one out of my saw, to get the measurements for you.

It appears to be made of a phenolac type composition, but I don't see why you couldn't use an acrylic or brass rod in its place.

I don't have a caliper handy, so the measurements were done with a steel rule.

The diameter is 1/2", length is 1 3/16"
