Default pantograph

Hi all,
I may be posting in the wrong place but the pantograph seems to fit in the "fixtures"arena. Please don't hesitate to correct me if that's a bad guess OK?
Getting ready to build a small Pantograph for my Dremel tool and would appreciate any suggestions/advice before I get started.I'm adapting/modifing plans downloaded from an article about a kit and/or plans from a company listed as "Bench-Craft".The article appears to be copied from an old book and it has complete plans as well as offering parts or a complete kit for sale. As I'm new here not sure if I should include the link. Anyway I've not cut any pieces yet and thought I'd ask for advice first (usually do it the other way around,LOL).
Thanks in advance,
Don,BP

Did you have any success?
I am also wanting to combine pantograph and dremel, i think it will be a good combination.

I spent the last hour searching for a pantograph for the dremel, but didn't have much luck. There were a few examples but nothing I would waste my time on. I have a full size pantograph from Milescraft and the thought ran through my head, "why not use the Milescraft as an example and downsize it by 50% or so and adapt it for the Dremel?" All it consists of is metal tubing and hardware to hold it together. Actually no heavier than the Dremel is 3/4 or 1 inch dowel rod could be used. The base plate to hold the Dremel could be made from 1/4" acrylic by cutting the hole the same size as the dremel nose without the screw on attachment and then use the screw on attachment to fasten the tool to the base plate. Just to clarify, I have the 4000 model Dremel so I am not sure if all Dremel's have a removable nose piece and if not another way to fasten the tool to the base plate would be in order. If you don't have a Milescraft Pantograph there are several pictures of it online that could be used as an example. In fact, later on today I will take a picture of mine and layout the measurements of each part on the picture to post in this thread.

When something is advertised as being foolproof there is always a better class of fool that comes along to prove them wrong.

Here is picture of pantograph with measurements and other info. There is a video on You Tube showing set-up and operation of the pantograph that will also be of help. Just search for Milescraft Pantograph.

If I can be of further help please ask.

Smudge,
Sorry for the slow comeback but havn't been on here for a while.Yes it works great,I'll take some pics and post them soon.The only little problem I had was getting a stylus/cutter combination for the tight areas of my origional pattern.
The finished piece is a pattern for a mold for casting an aluminum plaque. Once I figured out that some really tight areas would have to be finished with an X-acto knife,it was a breeze to do.
Don't think I'd change the pantograph as it seems to work well and was an easy build. There was a short"learning curve"but also not much of a problem....
More to come...

Think I mentioned finding an article about the pantograph earlier but you might try googling " Making and using a Carving Pantograph" that's where the article was that had a plan which I then modified to fit my purpose. Thought it needed beefing up in a couple of places and I only wanted the 50% reduction mode. The changes made were to prevent any twisting between members and stiffen the stylus so I could make several passes at different depths to reduce stress on the cutter. Mine also has nylon bearings at each pivot making the whole operation smoother.Check out the pics and let me know if I can be of any help...

Hi blindpig

Nice Job , but did you know that you can buy the rig below for a song off ebay for about 80.oo, it will make a 1 to 1 copy and copy just about anything and make signs easy as 1,2,3..

You could call it a ski jig on wheels so to speak
That should get Harry off his chair

Hey Bob,
Wow! that's a really neat carving machine,good to know about it,thanks.
In my case I needed the reduction and already having the dremel tool ,only have about $11.00 invested in bearings and shafts plus some scrap wood etc. Glad there's "more than one way to skin a cat" LOL.....Actually that's what's so cool about this forum.

Don,
Cheers for the reply, i also am in need of the reduction at this stage, although i will be building a replicating rig next. [if all goes well!]
The rig you have built is almost exactly the same as my scribblings!
Just hope mine looks/performs half as well as yours.
Rather than mount the Dremel itself, i am planning on using the Flex shaft on mine as will keep the weight down and hopefully lower stresses on the pantograph.
Will hopefully be beginning production next week so will show progress if any!
