First attempt at bench running elliptical moulding

[Cisco]

Thanks to the info on this site and a few others I made my first attempt @ bench running some elliptical moldings.

That looks really smart mate, are you self learning, or at college?

 

[flynnyman]

Nice work

 

[Djr]

Yes nice work pal

 

[Davy sned]

Tidy looking piece of work keep the pics coming

Thanks for the comments!

Basically self taught. No college or training ,went to work when I was young after leaving school. Been installing interior stone for the past 3 decades so I have experience in figuring s**t out and have been on jobs were guys were installing fibrous plaster and running in situ, thought I would give it a go.

You should be really proud of that as a first attempt. I have been teaching my self bits of insitu running, I'm really enjoying it! Are you going to do any other decrative pieces?

 

[choppa]

Lovely bit of work

 

[Nicm]

Good work,full respect,

 

[Danny]

Thats tidy (not that I know anything about fibrous)

 

[puddove]

keep up the good work ; bang tidy

A few progression shots. Finished moulding, keystone and mold, and my little helper

looks good fella,
but defiantly the long way round,
ellipse can be run quickly, easily and to a perfect ellipse using a trammel.

Unfortunately a trammel will not work for this application, I can mark a perfect ellipse with the trammel but I could not use it to run moulding as the major and minor axis have an extreme offset. The major axis is over 180cm and the minor axis is about 19cm. Because the trammel uses pivot points sliding through a preset tracks and not true radius running the knife noticeably would drag through the run skewed once it is off the major and minor axis center points. I attached a cad screenshot to visually explain it, not sure if I am explaining it good enough. In the screenshot you can see the three colored points the knife would run using a trammel. The yellow indicates major axis center pint where the moulding is 107.95mm wide, at the cyan colored line point the knife is running skewed and the moulding is now @ about 101.6mm, at the green colored line point the moulding is now @ about 92mm, as you continue through the run the knife would correct itself When parallel to the major axis. The white lines are the radius angles the knife should be at.

yup with you on that

Sorry guys, it wasn't my intent to confuse, just wanted to point out some of the limitations of using a trammel with an oblong ellipse. I try it again with a less confusing drawing.

Cheers

Hahaha I think it is a case of not having any idea about it at all (thats me especially)

 

[mikeadams1985]

cisco, i get ya, it becomes off square so to speak and the more off square the narrower the mould gets.
had that before with a huge mould we had to run but it was a random shape so was a c**t to run without going offsquare

Good job

 

[Vincenzo dupris]

Good job

I run this curve on a glass table

Sorry for the two year wait. Some install photos.

Looks great work
..fitted cornice and mouldings but making is something I've never got involved in but looks interesting work

two years but worth the wait

 

[Danny]

Looks great

Total respect, nice job.

Inspirational, love it and enjoyed the photos.

I've never seen that orange flexi-curve before, has it a name? I'd like to get one. Also, is it mini castors I can see on the side of your horse?
